I think the easiest way before messing up with middleware or whatever is to simply create a model for your logged emails and add a new record if send was successful.

Thanks Amyth for the hints. btw the commands is a bit different, i will post a 10x tested result here. Using south 1. setup the model python manage.py schemamigration models --initial dump data if you have to python manage.py dumpdata -e contenttypes -e auth.Permission --natural > data.json syncdb python manage.py syncdb python manage.py migrate models load the data back into the db python manage.py loaddata data.json Afterwards, you may use python manage.py schemamigration models --auto python manage.py migrate models after every change you made in the models schema A few notes 1. Unloading the database and reload it is essential, because if not doing so the first migration will tell you already have those models. 2. The -e contenttypes -e auth.Permission --natural parameter in dumpdata is essential otherwise exception will be thrown when doing loaddata.

You could run each each domain site independently using their own settings. This way you can control how much they share using the same codebase. Create separate settings for both sites. Where each of the settings specify a different ROOT_URLCONF and any extra setting required such as ALLOWED_HOSTS. Create two separate URL files for each site so you can specify exactly what URLs you want to make available for that given domain, make sure this is specified in each ROOT_URLCONF setting. Run each site as a separate instance using the settings you have already created. Example using the development server. python manage.py --settings package.settings.site_a

From your description, you will need to use (something like) django-guardian. Default Django permissions only apply to models(/tables). You cannot give someone permission to edit a specific article, category, comment or tag (only all articles, all categories, etc).

I'm starting to use django and read a lot of documentation in the last days. I also read about the permission system as well as about other systems like django guardian package. I'm trying to implement a multi-user blogging system and I'm not sure if I shall use django permissions or something else, like django guardian. Is there a rule of thumbs? Is migrating easy (starting with standard permissions and later on something else). Thank you!

Pyenv choose virtualenv directory

Short answer: You can’t, as far as I know. It wouldn’t really work either, right? If you use pyenv virtualenv to install a virtualenv into a repo, and you clone that repo to another machine… how would pyenv on the new machine know to take control of the virtualenv in the repository? Also, “you probably shouldn’t do that”. Virtualenvs are not 100% decoupled from the underlying Python installation, and aren’t really all that portable. And do you really want to litter your repositories with a bunch of easily replicated junk? The “right” way to go about things is probably to to maintain a requirements.txt for pip — that way you can easily reproduce your development environment wherever you clone your repo. That all said, there’s nothing stopping you from using plain old virtualenv to create a virtualenv anywhere you like, even if you installed virtualenv into a Python interpreter under pyenv control. That virtualenv itself will of course not be administered by pyenv, but you can still use it as you always did…

I just began to use pyenv to manage my python versions, and began to use the pyenv virtualenv plugin to manage my virtualenvs, and so far, I have loved it. One thing I miss however, is that with virtualenv, you could actually place virtual environments in repository directories so that your repository was a completely reproducible environment. Does anyone know of a way to choose the directory of your virtualenv in pyenv?

When are create and update called in djangorestframework serializer?

I finally understand how the .create() and .update() work in Serializer (especially ModelSerializer) and how they are connected to Viewsets (especially ModelViewSet). I just want clarify the concept more clearly if someone comes to this question. Basically, the 4 methods CRUD in ModelViewSet: .create(), .retrieve(), .update(), and .destroy() will handle the calls from HTTP verbs. By default, the .create() and .update() from ModelViewSet will call the .create() and .update() from ModelSerializer by calling the .save() method from the BaseSerializer class. The save() method will then determine whether it will call .create() or .update() in ModelSerializer by determining whether the object self.instance exists or not.

I'm currently implementing djangorestframework for my app RESTful API. After playing around with it, I still do not clearly understand what .create(self, validated_data) and .update(self, validated_data) used for in the serializer. As I understand, CRUD only calls the 4 main methods in viewsets.ModelViewSet: create(), retrive(), update(), and destroy(). I also have already tried to debug and print out stuff to see when the .create() and .update() methods are called in both ModelViewSet and ModelSerializer. Apparently, only the methods in ModelViewSet are called when I do the HTTP verbs. However, for ModelSerializer, I don't see any calls in those 2 methods. I just want to know what are those methods used for in ModelSerializer since I see that people override those methods a lot in the serializer.

When dealing with multiple languages, the way for debugging is regular debugging in one and remote debugging in the other... I'm guessing the ant debug uses the regular java debug which supports remote debugging, so, you can probably try that (although I haven't tried it here to confirm).

I have a set of Python scripts that sets up various parameters/properties for ANT script based on various conditions that are checked in the Python scripts and then invokes/executes the appropriate ANT build script. I initiate the Python script from my Eclipse IDE. I have the PyDev plug-in installed in Eclipse. I am able to debug the python script but cannot debug the ANT scripts, maybe because it doesn't get invoked as 'Run ANT Script'. Is there a way to debug an ANT script initiated by Python (or any other mechanism for that matter)?

What is the difference between creating db tables using alembic and defining models in SQLAlchemy?

Yes, you are thinking about it in the wrong way. Let's say you don't use Alembic or any other migration framework. In that case you create a new database for your application with the following steps: Write your model classes Create and configure a brand new database Run db.create_all(), which looks at your models and creates the corresponding tables in your database. So now consider the case of an upgrade. For example, let's say you release version 1.0 of your application and now start working on version 2.0, which requires some changes to your database. How can you achieve that? The limitation here is that db.create_all() does not modify tables, it can only create them from scratch. So it goes like this: Make the necessary changes to your model classes Now you have two options to transfer those changes to the database: 5.1 Destroy the database so that you can run db.create_all() again to get the updated tables, maybe backing up and restoring the data so that you don't lose it. Unfortunately SQLAlchemy does not help with the data, you'll have to use database tools for that. 5.2 Apply the changes manually, directly to the database. This is error prone, and it would be tedious if the change set is large. Now consider that you have development and production databases, that means the work needs to be done twice. Also think about how tedious would it be when you have several releases of your application, each with a different database schema and you need to investigate a bug in one of the older releases, for which you need to recreate the database as it was in that release. See what the problem is when you don't have a migration network? Using Alembic, you have a little bit of extra work when you start, but it pays off because it simplifies your workflow for your upgrades. The creation phase goes like this: Write your model classes Create and configure a brand new database Generate an initial Alembic migration, either manually or automatically. If you go with automatic migrations, Alembic looks at your models and generates the code that applies those to the database. Run the upgrade command, which runs the migration script, effectively creating the tables in your database. Then when you reach the point of doing an upgrade, you do the following: Make the necessary changes to your model classes Generate another Alembic migration. If you let Alembic generate this for you, then it compares your models classes against the current schema in your database, and generates the code necessary to make the database match the models. Run the upgrade command. This applies the changes to the database, without the need to destroy any tables or back up data. You can run this upgrade on all your databases (production, development, etc.). Important things to consider when using Alembic: The migration scripts become part of your source code, so they need to be committed to source control along with your own files. If you use the automatic migration generation, you always have to review the generated migrations. Alembic is not always able to determine the exact changes, so it is possible that the generated script needs some manual fine tuning. Migration scripts have upgrade and downgrade functions. That means that they not only simplify upgrades, but also downgrades. If you need to sync the database to an old release, the downgrade command does it for you without any additional work on your part!

I could create tables using the command alembic revision -m 'table_name' and then defining the versions and migrate using alembic upgrade head. Also, I could create tables in a database by defining a class in models.py (SQLAlchemy). What is the difference between the two? I'm very confused. Have I messed up the concept? Also, when I migrate the database using Alembic, why doesn't it form a new class in my models.py? I know the tables have been created because I checked them using a SQLite browser. I have done all the configurations already. The target for Alembic's database and SQLALCHEMY_DATABASE-URI in config.py are the same .db file.

Email API for connecting in a marketplace?

What you're describing would be handled largely by your backend. If this were my project, I would choose the following simple route: Store the messages the buyers/sellers send in your own database, then simply send notification emails when messages are sent. Have them reply to each other on your own site, like Facebook and eBay do. An example flow would go like this: (Gather the user and buyer's email addresses via registration) Buyer enters a message and clicks 'Send Message' button on seller's page Form is posted (via AJAX or via POST) to a backend script Your backend code generates an email message Sets the 'To' field to the seller Your seller gets an email alert of the potential buyer which shows the buyer's message The Seller then logs on to your site (made easy by a URL in the email) to respond The Seller enters a response message on your site and hits 'Reply' Buyer gets an email notification with the message body and a link to your site where they can compose a reply. ...and so on. So, replies would have to be authored on-site, rather than as an email 'reply.' If you choose to go this route, there are some simple 3rd party "transactional email" providers, which is the phrase you'd use to find them. I've personally used SendGrid and found them easy to set up and use. They have a simple plug in for every major framework. There is also Mandrill, which is newer but gets good reviews as well.

I'm looking into what it would take to add a feature to my site so this is a pretty naive question. I'd like to be able to connect buyers and sellers via an email message once the buyer clicks "buy". I can see how I could do this in java script, querying the user database and sending an email with both parties involved. What I'm wondering is if there's a better way I can do this, playing monkey in the middle so they only receive an email from my site, and the it's automatically forwarded to the other party. That way they don't have to remember to hit reply-all, just reply. Also their email addresses remain anonymous. Again assuming I generate a unique subject line with the transaction ID I could apply some rules here to just automatically forward the email from one party to the other but is there an API or library which can already do this for you?

Django model for datetime availability

On the item's model, add two datetime fields, for example "bookedStart" and "bookedEnd". And have a function isBooked() that checks if a given datetime or the current datetime is in that time frame, and return True if it is, or False otherwise. If the users should be able to add multiple time frames (at once) when an item is available or not, you can make a separate model for it, for example BookedItem, and add in it start and end datetime fields, and foreign fields to the user and item. And again, a isAvailable() or isBooked() function.

can one spider handle multiple items and multiple pipelines?

30,448,526

python,web,scrapy

Item refers to an item of data that it's scraped. You can also call it a record or an entry. Spider is the thing that does crawling (starting requests and following links) and scraping (extracting data items from responses). They can schedule whatever amount of requests and extract whatever amount of items as you want, there isn't any limit. Item pipelines are an abstraction to process the items that are extracted by a spider. The idea is that you can combine different "pipes" through which the data items will come through, and then you'll arrange them in a way that will accomplish whatever you need. Examples of use cases for pipelines are applying validation constraints, saving data into a database, doing some clean-up on the data (e.g., remove HTML tags), etc. So, recapping: Spiders extract data items, which Scrapy send one by one to a configured item pipeline (if there is possible) to do post-processing on the items.

CSRF verification fails when trying to login in an already logged in application Django

This is to be expected. The login operation rotates the CSRF token, otherwise it would be possible to use the token from outside the authenticated session. Hence what happens in your case: Retrieve login page in Tab 1 (with unauthenticated "form" CSRF token) Retrieve login page in Tab 2 (with unauthenticated "form" CSRF token) Login in Tab 1, CSRF "cookie" token gets cycled server side, browser cookie gets updated Try to login in Tab 2, sends new cookie (tabs do not separate sessions), but old "form" token. Second login request is rejected (because "form" token and "cookie" token mismatch). This is an interaction between the fact that using multiple browser tabs do not separate sessions and the fact that the login operation cycles the "cookie" CSRF token sent to you by the server. Any page loaded before the login operation that takes place in the same session (e.g. in a different browser tab) will now have an incorrect CSRF "form" token.

Flask is a relatively simple web framework. It will suit your need to get the user-submitted text into a python function, without too much boilerplate code or complexity. There are alternatives, most notably Tornado. I do wonder why you would stack two REST interfaces on top of eachother. Do you need the node.js application for specific reasons? If not, you can simplify your architecture.

I'm trying to build a sentiment classifier web app, but I don't understand who to connect the machine learning component with the web app. I've built the client-side web app that's running on a NodeJS server, and I've trained a sentiment classifier that saved as a Python script. My goal is to have users submit text on the web app, send it to the Python script, classify, and send the result back via JSON. How should I setup the Machine Learning-Web App pipeline? One suggestion was to load the Python script in Flask, and use Flask as a REST API. It seems as though using Flask would be overkill since I only need to do one task.

This seems like a bad idea. Out of the box, the information architecture presented by the admin interface is going to be very flat where views essentially mirror what's in the database 1:1. I can imagine a slim subset of users in internal IT apps or similar where that may be appropriate but the compromises in usability are serious, without modifying the admin interface so much that you'll probably wish you had done your app the traditional way by the time you were done. If usability and information architecture are not serious concerns or requirements for your app, then you may proceed apace.

I am about to begin work on a project that will use Django to create a system with three tiers of users. Each user will login into the dashboard type interface (each user will have different types of tools on the dashboard). There will be a few CRUD type interfaces for each user tier among other things. Only users with accounts will be able to interact with the system (anyone visiting is greeted with a login screen). It seems that many people recommend to simply modify the default Admin app to fit the requirements. Is this an ideal solution and if so, how do I set so the admin interface is at the site's root (instead of admin/). Also, any documentation on in-depth and secure modification of the admin interface (along with the addition of different user tiers) would be appreciated.

I am creating a Django site that will have 4 types of users; Super Admin: Essentially manages all types of users UserTypeA: Can login to site and basically will have a CRUD interface for some arbitrary model. Also has extra attributes (specific info that only pertains to TypeA users) UserTypeB: Can login to site and has extra information that pertains specifically to TypeB users, also can create and manage TypeC user accounts UserTypeC: Can login to site and has extra information that pertains only to TypeC users. Noting that I plan on creating a custom interface and not utilizing the built-in admin interface. What would be the best method for implementing this user structure? I would prefer to use Django's built-in authentication system (which manages password salting and hashing, along with session management etc), but I would be open to using some other authentication system if it is secure and production ready. EDIT: Also, my plan is to use 1 log-in screen to access the site and utilize the permissions and user type to determine what will be available on each user's dashboard. EDIT: Would it be possible to accomplish this by using an app for each user type, and if so how would this be done with a single log-in screen.

First, the server setup: nginx frontend to the world gunicorn running a Flask app with gevent workers Postgres database, connection pooled in the app, running from Amazon RDS, connected with psycopg2 patched to work with gevent The problem I'm encountering is inexplicably slow queries that are sometimes running on the order of 100ms or so (ideal), but which often spike to 10s or more. While time is a parameter in the query, the difference between the fast and slow query happens much more frequently than a change in the result set. This doesn't seem to be tied to any meaningful spike in CPU usage, memory usage, read/write I/O, request frequency, etc. It seems to be arbitrary. I've tried: Optimizing the query - definitely valid, but it runs quite well locally, as well as any time I've tried it directly on the server through psql. Running on a larger/better RDS instance - I'm currently working on an m3.medium instance with PIOPS and not coming close to that read rate, so I don't think that's the issue. Tweaking the number of gunicorn workers - I thought this could be an issue, if the psycopg2 driver is having to context switch excessively, but this had no effect. More - I've been working for a decent amount of time at this, so these were just a couple of the things I've tried. Does anyone have ideas about how to debug this problem?

Running complex calculations (using python/pandas) in a Django server

I assume your question is about "how do I do these calculations in the restful framework for django?", but I think in this case you need to move away from that idea. You did everything correctly but RESTful APIs serve resources -- basically your model. A computation however is nothing like that. As I see it, you have two ways of achieving what you want: 1) Write a model that represents the results of a computation and is served using the RESTful framework, thus your computation being a resource (can work nicely if you store the results in your database as a way of caching) 2) Add a route/endpoint to your api, that is meant to serve results of that computation. Path 1: Computation as Resource Create a model, that handles the computation upon instantiation. You could even set up an inheritance structure for computations and implement an interface for your computation models. This way, when the resource is requested and the restful framework wants to serve this resource, the computational result will be served. Path 2: Custom Endpoint Add a route for your computation endpoints like /myapi/v1/taxes/compute. In the underlying controller of this endpoint, you will load up the models you need for your computation, perform the computation, and serve the result however you like it (probably a json response). You can still implement computations with the above mentioned inheritance structure. That way, you can instantiate the Computation object based on a parameter (in the above case taxes). Does this give you an idea?

I have developed a RESTful API using the Django-rest-framework in python. I developed the required models, serialised them, set up token authentication and all the other due diligence that goes along with it. I also built a front-end using Angular, hosted on a different domain. I setup CORS modifications so I can access the API as required. Everything seems to be working fine. Here is the problem. The web app I am building is a financial application that should allow the user to run some complex calculations on the server and send the results to the front-end app so they can be rendered into charts and other formats. I do not know how or where to put these calculations. I chose Django for the back-end as I expected that python would help me run such calculations wherever required. Basically, when I call a particular api link on the server, I want to be able to retrieve data from my database, from multiple tables if required, and use the data to run some calculations using python or a library of python (pandas or numpy) and serve the results of the calculations as response to the API call. If this is a daunting task, I at least want to be able to use the API to retrieve data from the tables to the front-end, process the data a little using JS, and send it to a python function located on the server with this processed data, and this function would run the necessary complex calculations and respond with results which would be rendered into charts / other formats. Can anyone point me to a direction to move from here? I looked for resources online but I think I am unable to find the correct keywords to search for them. I just want a shell code kind of a thing to integrate into my current backed using which I can call some python scripts that I write to run these calculations. Thanks in advance.

AWS doesn't "know" anything about your content. The webserver that you install will be configured to point to the "root" directory in which index.html (or something equivalent) should be. Since it depends on which webserver (django, flask, Jinja etc) you install - you should lookup its documentation!

You can't reuse the Users service authentication across different applications. A possible solution could be using a OAuth2 (or a similar mechanism) - create an application (or use one of you existing applications) which will be the authentication provider. Each application will redirect to the authentication provider where the user will get authenticated, and then redirected back. If the user is already authenticated, they will not need to authenticate again when switching applications. This way you won't be able to use the Users service on the end applications, only in the provider, so you will need to rely on another way to store the currently logged in user in each application (like datastore+memcache).

Django app is actually a python package that follows the Django convention. Django-admin startapp is just a helper command to create the files in that convention. If you want to create an app without using startapp, then can create a folder and create __init__.py file and create the necessary files(for views and models). And you should include it in the INSTALLED_APPS. That's all.

I know how permissions/groups/user work together in a "normal" way. However, I feel incomfortable with this way to do in my case, let me explain why. In my Django models, all my users are extended with models like "Landlord" or "Tenant". Every landlord will have the same permissions, every tenant will have other same permissions.. So it seems to me there is not interest to handle permission in a "user per user" way. What I'd like to do is link the my Tenant and Landlord models (not the instances) to lists of permissions (or groups). Is there a way to do this? Am I missing something in my modelisation? How would you do that?

How to import a 3rd party Python library into Bluemix?

The cause for this problem was that I was not correctly telling my Python app the needed configuration information when I pushed it out to Bluemix. What I ended up having to do was add a requirements.txt file and a Procfile file into the root directory of my Python application, to draw that connection between my Python app and the needed libraries/packages. In the requirements.txt file I specified the library packages needed by my Python app. These are the file contents: web.py==0.37 wsgiref==0.1.2 where web.py==0.37 is the version of the web.py library that will be downloaded, and wsgiref==0.1.2 is the version of the web server gateway interface that is needed by the version of web.py I am using. My Procfile contains the following information: web: python .py $PORT where myappname is the name of my Python app, and $PORT is the port number that my Python app uses to receive requests. I found out too that $PORT is optional because when I did not specify $PORT my app ran with the port number under the VCAP_APP_PORT environment variable for my app. From there it was just a matter of pushing my app out to Bluemix again only this time it ran fine.

I would recommend you use a separate process for your app that will receive REST commands (use Pyramid or Flask), and have it send messages over RabbitMQ to the real time part. I like Kombu myself for interfacing with RabbitMQ, and your message bus will nicely decouple your web/rest needs from your event driven needs. Your event driven part just gets messages off the bus, and doesn't need to know anything about REST.

I am working on a Python 2.7 project with a simple event loop that checks a variety of data sources (rabbitmq, mongodb, postgres, etc) for new data, processes the data and writes data to the next stage. I would like to embed a web server in the application so it can receive simple REST commands, for shutting it down, diagnosis etc. However, from reading the documentation on the available web servers it wasn’t clear if they will allow the event loop described above to function outside of the web server’s event loop. Ie. it looks like I would have to do something like launch the event loop using a REST call and have the loop live on an io thread, or similar. Can someone explain which embedded server (cherrypy, bottle, flask, etc) / concurrency framework (tornado, gevent, twisted etc.) are best suited for this problem? Thank you in advance!

I've got a template for a subject.html page and a view that loads from the url appname/subject/subjectname what I need to do is apply particular css to style the page according to the subject accessed. for example if the user goes to appname/subject/english I want the page to be "themed" to english. I hope I've made myself clear, also I would like to know if there is a way I can add actual css code to the stylesheet and not have to change attributes one by one from the back-end. thanks very much!

PayPal doesn't have a way for people to sign up entirely through your site, although there are some ways to facilitate the process. You'd probably have to call PayPal to get access to some of those as they are aimed primarily at larger businesses. However, don't neglect the easy/automatic assistance that PayPal gives you: you can pay to any email account, and if that email is not already active on a PayPal account then the payment will be waiting for them when they activate that email into an existing or new PayPal account. So you can onboard merchants to your site and leave the PayPal signup for later, when money will be waiting for them to claim. Psychologically, walking away from money is harder than than deciding not to start processing :).

1) I am not very familiar with Python, but for the .net application you will likely want to push change notifications to it, rather than pull. The system.net.webclient.downloadstring is a request (pull). As I am not a Python developer I cannot assist in that. 3) As you are requesting data, it is possible to create some errors of the read/write while updating and reading at the same time. Even if this does not happen your data may be out of date as soon as you read it. This can be an acceptable problem, this just depends of how critical your data is. This is why I would do a push notification rather than a pull. If worked correctly this can keep data synced and avoid some timing issues.

I am writing a client-server type application. The server side gathers constantly changing data from other hardware and then needs to pass it to multiple clients (say about 10) for display. The server data gathering program will be written in Python 3.4 and run on Debian. The clients will be built with VB Winforms on .net framework 4 running on Windows. I had the idea to run a lightweight web server on the server-side and use system.net.webclient.downloadstring calls on the client side to receive it. This is so that all the multi-threading async stuff is done for me by the web server. Questions: Does this seem like a good approach? Having my data gathering program write a text file for the web server to serve seems unnecessary. Is there a way to have the data in memory and have the server just serve that so there is no disk file intermediary? Setting up a ramdisk was one solution I thought of but this seems like overkill. How will the web server deal with the data being frequently updated, say, once a second? Do webservers deal with this elegantly or is there a chance the file will be served whilst it is being written to? Thanks.

Well, that really is not how it works. Each view is separate and is only called from the URLs that map to it.

I was wondering how to call my index(request) function thats in views.py upon every page reload. Currently index(request) only gets called when the app originally loads. Every other page reload after that calls another function in views.py called filter_report(request). The problem I am running into is that 85% of the code in filter_report(request) is also in index(request) and from my understanding you don't really want 2 functions that do a lot of the same stuff. What I would like to do is take that 15% of code that isn't in index(request) but is in filter_report(request) and split it into different methods and just have index(request) call those other methods based on certain conditionals.

You should track migrations. The only thing that you must keep an eye out for is at branch merge. If everyone uses a feature branch and develops on his branch then the changes are applied once the branch is integrated. At that point (pull request time or integration time) you need to make sure that the migrations make sense and if not fix them.

Suppose you write a Django website and use git to manage the source code. Your website has various instances (one for each developer, at least). When you perform a change on the model in a commit, everybody needs to update its own database. In some cases it is enough to run python manage.py migrate, in some other cases you need to run a few custom SQL queries and/or run some Python code to update values at various places. How to automate this? Is there a clean way to bundle these "model updates" (for instance small shell scripts that do the appropriate actions) in the associated commits?

The main advantage of using a Cloudant/CouchDB library is that you write less code. This can be significant in languages like Java where Rest and JSON handling is very cumbersome. However working with Rest and JSON in python using standard libraries is very easy. However, the main disadvantages of using a Cloudant/CouchDB library are: you have less control over the interaction with Cloudant which may make things like session management and http connection pooling much harder. You don't get to learn the Cloudant API as this is abstracted away from you by the library. Some libraries allow you do to things which can be problematic for scalability such as py-couchdb's functionality for creating temporary views. Libraries may not implement the full Cloudant API so you may end up having to make Rest/JSON calls to access these features not implemented by the library.

I have a very basic CGI based front end hosted on an IIS server. I'm trying to find the users within my shop that have accessed this site. All users on the network sign on with their LAN (Windows) credentials and the same session would be used to access the site. The python getpass module (obviously) returns only the server name so is there a way to find the user names of the visitors to the site? The stack is Python 2.7 on IIS 8.0, Windows Server 2012

What you can do is lock the slot for the booking once the payment is initiated. That way you only "lose" availability for a few moments. The lock can be done on the same centralized system that holds the rest of the information. For instance you can scale up the application servers but keep a single entry point to the data source. You release the lock once the payment is declined or confirm.

I have a Django Model class for a booking slot. Once we have all the auxiliary data and payment is ready to be made, we get a live availability and allocate a booking. This whole last step of the process takes a couple of seconds (mostly waiting on the payment provider to clear). In theory two payments coming through at once could double-book a slot. That's all handled by a single function Booking.book(). Is there any sane way I can limit so that only one instance can work at once and others are queued? The deployment design is initially pretty simple but there could be scale to multiple servers eventually. What's the proper way of doing this and what are its downsides?

I want to create a view having a form, But the form should not show any fields. In the view I has to be able to confirm/accept the object and thus change the status field of the object. I guess I can make a simple view inheriting from FormView without creating any input fields, find the object in the dispatch method, and change the status field in the form_valid method. But I wondered if it's better to use UpdateView since it has already implemented get_object, etc. I have to use this approach many times, so I want to do it right the first time.

This question can be answered by another question: What is the difference between procedural and object oriented programming? Class based views provide you the power of OOP. Code becomes reusable and abstract. The modularity improves. Performance wise, I guess there is no difference between a class based and a function based view. It all depends on with which you are more comfortable. Both are just meant for different styles of programming.

You can only start or stop AWS RDS instance of single availability zone instances. For your case, you will have to check if the multi-AZ option is enabled or disabled. Incase your database is in Multiple availability zone, the best way would be to take the snapshot and restore it.

Ok so I found the problem. as patrys sugested in a comment the file didn't use UTF-8 as encoding. To change that in pycharm I had to go to file->settings->editor->file encodings and change the file encoding for tests to utf-8. After I did that I had to go into the file and re eddit the § as they have now turned into question marks. However it still didn't work. I found out that I also have to change it to UTF-8 down in the right corner of pycharm. For some reason tests is the only .py file that was affected by this (even though I deleted the original tests.py file and remade it).

When I run my tests I get a syntax error: SyntaxError: (unicode error) 'utf-8' codec can't decode byte 0xa7 in position 0: invalid start byte The cause of this seems to be that I use a § in a string on line 62. I'm using python 3.4.2 for the project and have used § elsewhere without getting a error. I got a friend to open the project as well, on his screen the § in tests.py showed up as question marks, but this was only in the test files, in the other places it had been used it showed up as normal. I got him to change the § that were showing up as question marks to § on his pc and it worked, which is really weird. How would I go about fixing something like this on my computer though? I can't really get him to load up the file and insert special character every time I want to use them in tests. edit: So I found out pycharm for some reason had set only tests.py to a encoding other than utf-8. I changed this to utf-8 and it then showed the § I had written as question marks. However swapping them out for § did not work for me. The reason is that for some reason even though the encoding is set to utf-8, pycharm still displays latin1 for me and type latin1 characters instead of utf-8. I've tested on 2 other computers (1 mac, and 1 windows 8.1 same as the one I have problems with) where it correctly displays utf-8. On those computers my § still appear as question marks, but if i change it on the other computer it now appears as Â§ on the computer with the problem. So my problem now is to get pycharm to properly use UTF-8 instead of latin 1.

Of course, I want to name it cool_project: my mother told me that Hungarian notation is bad and that the name cool_project is much better than any of cool_project_web etc. But now I have a collision. As long as I try importing cool_project (the backend one) from django/cool_project/views.py (the views.py of the main Django app) a frontend package is being imported. Is there any way to import backend project in this case? I tried to add full path to backend package (sys.path.insert(0, "/home/.../...")) but it didn't help. Or maybe there is some well-known naming convention which helps avoiding such collisions?

As @dirn stated, that is the nature of file uploads. You have two options to get around this. Save the uploaded file temporarily (especially if its large) while you prompt the user to fix the input error (as suggested by @dirn). This would require extra logic to purge files (assuming the user decides they don't want to submit form anymore or they go to a different page, etc) Validate your form using javascript so that the file only uploads when the form is actually valid (wtforms doesn't really help you much with this option)

Django Group and Permission applies on model itself. So for a specific entry of document if you want to give access to user in that case you need to change your schema of Document model. Just add a users_who_can_read=ManyToMany(Users), users_who_can_write=ManyToMany(Users), and at your view.py when a user is trying to load a page just check if he is in users_who_can_read or not. I think it should solve your problem without much problem.

I could see this being posted to the UX SE (ux.stackexchange.com I think?) site, or they might already have a question there touching on something like this. But personally I would probably lean toward either a dropdown selector with different types, or keeping the separate searches as-is. And I think I'd lean more toward the dropdown box - that doesn't seem unreasonable to me for a search interface. I guess one question would be - could there be any expectation to want results from more than one of the tables in the same search? If that were the case I could see implementing your unified search idea even though it would mean querying multiple tables. Or some sort of additive interface where you select the tables you'd want to query.

Not sure if this question is better suited for a different StackExchange site but, here goes: I have a search page that searches a number of different type of things. All (at the moment) requiring a different input field for each type of search. For example, one might search for a school or district name, a class name, a staff member email address, etc. I have 9 different 'type' of searches each with their own input field on the search page. I've already concatenated one of these (a username and UID search) but I'm wondering if it makes sense both design (user friendly) and performance wise to bring these all into one input field (and therefore one singular search) These different types are of course a number of different tables, so it would have to query a number of different times for each type, just for one search. Any ideas? or should I just keep it how it is? I could add a drop-down menu to choose a different 'type' of search but that seems just as messy. I'm already doing this for my navbar when not on the main search page (which also happens to be the home page) My project is written in Python with the Pyramid framework.

python,search,search-engine,pyramid

What happens to your search interface if the application changes? This is a very important aspect. Do you add another search type? A search returns matches on the query string. A result set can contain different entities from different types. Then your search/resultset interface could apply filtering based on entity type or entity facets (examples: Ebay, Amazon) Learn from Solr/elasticsearch and add-on projects. Faceted search is what users are used to these days. The concept of separating data storage (RDBMS) and full-text search engine is much more powerful and extendable compared to writing complex queries spanning multiple tables. Any larger internet company (Ebay, Facebook, Amazon, Instagram) can tell stories about using the patterns. Separating storage from search offers scalability, flexibility. Instead of writing query/search code, better learn how to feed these search engines from any data store. This is much more powerful & fun, I promise.

Wouldn't there be security issues at letting an external site dictate what your db's structure looks like? A problem of any kind (or a man in the middle attack) could completely modify (or destroy) your database without you doing anything. I'd say it's better to have API versions than what you're asking for. I'd prefer to have 2 concurrent versions running at the same time, to let the time for the API consumers to update their schemas, than force automatic updates of their schemas and data. And in general, if possible, I'd only use a single API version, taking care to always keep a compatibility with older implementations. But I'm just saying that for general public API, I don't know how open your API should be and how close your developpements (API and consumer) are, so I may be completely out of your scope!

I'm struggling with how to keep models in sync between my main application project, and this new Django project for the API... product development may continue in the application project that necessitates models changes, and I'd like those models changes to be propagated to the API project. Is there a way to point to, or import, models from a different Django project?

python,django,database,naming-conventions

The default convention is better and cleaner to use : It avoids any table naming conflict ( As It's a combination of App name and Model name) It creates well organized database (Tables are ordered by App names) So until you have any special case that needs special naming convention , use the default.

I'm working on GPIO stuff in Python, need to register the fd on epoll, since gevent monkey patched the python select library, there will not be select.epoll if monkey.patch_all(select=True), so here comes two questions: Will be consequence that the monkey.patch_all(select=False)? Or does Gevent provide its own epoll register stuff? Thank you in advance.

Python Relative Imports Only Work With Django

python,import

You can't simply execute main.py from dir2; you'll need a script of sorts that lives outside your whole app package, and then if you import app.dir2.main, you'll get app.dir1.utils as well through the relative import. Create a script that does from app.dir2 import main, then run that outside the app package. And use the from ..dir1 import utils in structure in main.py, with 2 leading dots. I can't give you the exact reason why this is, but I think essentially any script/module executed inside a directory is not going to look up the directory chain to see if it's part of a module. That is, the main.py module will not look into the app directory and think "hey, I'm part of a module, and I can (relatively) import dir1 as well.

Hi I use Django frequently and am constantly using relative imports along the lines of from .models import XXX for XXX in a models folder or from . import views for a file named views.py in same directory and it works fine there. But when I create my own Python application with a directory structure such as: app/ containing __init__.py, dir1, and dir2 dir1/ containing __init__.py, utils.py dir2/ containing __init__.py, main.py then say inside of main.py in dir2 I do from .dir1 import utils or even from ..dir1 import utils I get an error like: ValueError: Attempted relative import of non-package Which I don't understand as there is an __init__.py in all the directories. Why does it always work fine in django projects but not when I start my own python project from scratch? What should I be doing to import something like this? Obviously absolute imports are not preferred, but I can't get relatives to work. All the answers on SO and other sites that I have found never seems to provide a solution, or at least one that worked for me. Can someone please just tell me what the correct way to do an import like this is? Import a python file from a directory that is a sibling of the directory which contains the file I'm calling import from. Help would be much appreciated. Perhaps for once we can get a nice short answer that is actually to the point. All I really need is for someone to show me what I should be using to do this import, and secondarily explain why I don't get this error in django but get it here. I just want to get the imports working, every time I start my own python application outside Django (because it isn't web based) I have this issue and every answer I find is no help. EDIT: The problem I'm having is importing files from anything but a child directory or files within the same directory. The places I have the issue are when the file I need is in a sibling or parent directory. I need help making the import work for that.

Creating a centric REST API for a mobile and website application

Actually I doesn't make great sense. From my experience I know that mobile apps and web pages even if use the same backend very often require completely different set of data, and - (I know premature optimization is the root of all evil) - number of calls should be minimized for mobile applications to make them running smoothly. I'd separate mobile API from classic REST API, even with prefixes, e.g. /api/m/ and /api/. There're really many frameworks in a number of technologies. E.g. spring, django-rest-framework, express.js. Whatever you like. Token authentication will be the best choice. For both web and mobile. For REST in general. It shouldn't be a matter for you now.

What version of choco did you use to install PhantomJS (and what version of PhantomJS)? I believe we corrected this issue in most cases, but it is on newer versions of choco - and you need the shim to be generated in that newer version (which means install or upgrade, but we are adding a shim regen command).

I have some Python Selenium nose tests running on Windows 8 with PhantomJS. I installed Chutzpah (PhantomJS) via Chocolatey. When I run the nose tests, a "ShimGen" process appears and lots of "PhantomJS is a headless WebKit with JavaScript API (32 bit)" processes appear and use 50+mb of memory and never close. This causes a lot of stuck PhantomJS processes in memory. This eventually brings down the server.

I'm having problem on json output of scrapy. Crawler works good, cli output works without a problem. XML item exporter works without a problem and output is saved with correct encoding, text is not escaped. Tried using pipelines and saving the items directly from there. Using Feed Exporters and jsonencoder from json library These won't work as my data includes sub branches. Unicode text in json output file is escaped like this: "\u00d6\u011fretmen S\u00fcleyman Yurtta\u015f Cad." But for xml output file it is correctly written: "Öğretmen Süleyman Yurttaş Cad." Even changed the scrapy source code to include ensure_ascii=False for ScrapyJSONEncoder, but no use. So, is there any way to enforce scrapyjsonencoder to not escape while writing to file. Edit1: Btw, using Python 2.7.6 as scrapy does not support Python3.x This is as standart scrapy crawler. A spider file, settings file and an items file. First the page list is crawled starting from base url then the content is scraped from those pages. Data pulled from the page is assigned to variables defined in items.py of the scrapy project, encoded in utf-8. There's no problem with that, as everything works good on XML output. scrapy crawl --nolog --output=output.json -t json spidername Xml output works without a problem with this command: scrapy crawl --nolog --output=output.xml -t xml spidername I have tried editing scrapy/contrib/exporter/init.py and scrapy/utils/serialize.py to insert ensure_ascii=False parameter to json.JSONencoder. Edit2: Tried debugging again.There's no problem up to Python2.7/json/encoder.py code. Data is intact and not escaped. After that, it gets hard to debug as the scrapy works async and there are lots of callbacks. Edit3: A bit of dirty hack, but after editing Python2.7.6/lib/json/encoder.py and changing ensure_ascii parameter to False, the problem seems to be solved.

Python Module in Django

python,django

Definitely go for "way #1". Keeping an independent layer for your service(s) API will help a lot later when you have to enhance that layer for reliability or extending the API. Stay away from singletons, they're just global variables with a new name. Use an appropriate life cycle for your interface objects. The obvious "instantiate for each request" is not the worst idea, and it's easier to optimize that if needed (by caching and/or memoization) than it's to unroll global vars everywhere. Keep in mind that web applications are supposed to be several processes on a "shared nothing" design; the only shared resources must be external to the app: database, queue managers, cache storage. Finally, try to avoid using this API directly from the view functions/CBV. Either use them from your models, or write a layer conceptually similar to the way models are used from the views. No need of an ORM-like api, but keep any 'business process' away from the views, which should be concerned only with the presentation and high level operations. Think "thick model, thin views" with your APIs as a new kind of models.

I am building my first Django web application and I need a bit of advice on code layout. I need to integrate it with several other applications that are exposed through RESTful APIs and additionally Django's internal data. I need to develop the component that will pull data from various sources, django's DB, format it consistently for output and return it for rendering by the template. I am thinking of the best way to write this component. There are a couple of ways to proceed and I wanted to solicit some feedback from more experienced web developers on things I may have missed. Way #1 Develop a completely standalone objects for interacting with other applications via their APIs, etc... This would not have anything related with django and test independently. Then in django, import this module in the views that need it, run object methods to get required data, etc... If I need to access any of this functionality via a GET request (like through JavaScript), I can have a dedicated view that imports the module and returns json. Way #2 Develop this completely as django view(s) expose as a series of GET/POST calls that would all call each other to get the work done. This would be directly tied in the application. Way #3 Start with Way #1, but instead of creating a view, package it as a django app. Develop unit tests on the app as well as the individual objects. I think that way 1 or 3 would be very much encapsulated and controlled. Way 2 would be more complicated, but facilitate higher component re-use. What is better from a performance standpoint? If I roll with Way #1 or 3, would an instance of the object be instantiated for each request? If so this approach may be a bit too heavy for this. If I proceed with this, can they be singletons? Anyway, I hope this makes sense. thanks in advance.

I've been successfully using go for months - last night my app started 404 page not found errors but only on pages that use Templates. Those that don't use the Template system work fine. I re-installed the Go sdk and discovered that the Guestbook demo ( also uses Templates) doesn't work either. ... and then I noticed that links to the log files weren't appearing on the Instance page of the dev console - but when I click the "default" link it displayed the guestbook templated page that I had just requested and got the 404. It seems that the system can't find template folder and that is causing the 404s My configuration seems to have broken and I haven't been able to figure out why - hope someone can help... ...After messing with environment variables and stuff for a while with no success, I ran "test_Python" file. These all generated Errors: test_too_big_rewrite, module_test, python_sandbox_test all generated errors - the process hung up on "test_serve" This is causing my problems? Is there a way to correct? Uninstall and reinstall Python? Will I have to uninstall/reinstall Go SDK ? thanks!

I want to be able to test this functionality in my functional test in selenium, but I don't know how I would go about it. I obviously don't want to wait a day for the test to finish either.

Yes that's a way to parse HTML into a DOM tree. If other people don't do that, they might have other requirements. In general your idea is not bad, it might require more CPU time then other testing method (for example regular expressions. But if it fits your needs for testing, just do it. Performance it rarely a problem at testing time.

Is the solution simply to xml.dom.minidom.parseString the bytes of response.content? I couldn't find any examples of people doing this online or in Django manuals or tutorials, which makes me wonder if there's a reason for not doing it this way? If it's bad practice and there's a better way to do this please can you say why and what?

I tried to use xvfb to create a virtual display but it did not worked, tried all solutions on some answers here but nothing changed. So i saw pyvirtualdisplay library of Python but it seems like helpful with tests written in Python. I'd like to know that if I am able to run test suites that i wrote in robotframework (which are .txt formatted and could be runnned via pybot) via Python so i can use pyvirtualdisplay?

php,python,ios,server,backend

No it should not cause an error, you are requesting the server with an HTTP method(POST) which serves every request from a new user as a new request because HTTP is a stateless protocol it doesn't save user states(unless you are managing user sessions explicitly) So if 100 users are requesting at the same time, they are different, each request is different and same will be the response(different) for each user. And as others said, its completely dependent on the server how it handles the request.

Pickle files is good way to load data in python. By the way consider using the C implementation: cPickle. If you want to scale, using pickle files. Ideally you want to look for a partition key, that fits for your data and your project needs. Let's say for example you have historical data, instead of having a single file with all historical data, you can create a pickle file per date.

I am working on my first web application. I am doing it in Python with Flask, and I want to run a piece of Python code that takes an object, with Pickle, from a (binary) file of several MB which contains all the necessary data. I have been told that so using Pickle in a web app is not a good idea because of scalability; why? Obviously, for a given purpose it's better to take just the necessary data. However, if I do this, with an Elasticsearch database and in the fastest way I can, the whole process takes about 100 times more time than if I take all the data at once from the binary; once the binary is unpickled, which will take at most one second, the computations are very fast, so I am wondering if I should use the binary file, and if so, how to do it in a scalable way.

Developing directly in production environment is highly discouraged. You should develop locally using version control systems (git) and test suites to check everything works before the deploy. Once you've checked everything works, you can pull changes from the remote repository to apply the modifications or use something like jenkins for continuous integration. But, if you still want to modify your code directly in the cloud. Pycharm is a nice IDE that allows you to work with remove projects. I don't know if this is possible with Sublime.

Check the redirect URL. I had wrongly specified redirect URL along with client ID while making post request. For Facebook redirect URI is optional. Try removing that and it will work fine.

This option was removed because you can explicitly add id field to the create and edit forms.

Previous version of Flask-Admin had a hide_backrefs option which could be set to False if you wanted to show them in the admin view. The current version seems to have it no longer. Does it go by some other name? If I want to display backreferences in the admin list view, is there a better solution than just manually setting columns_list?

TypeError: SetStrength() missing 1 required positional argument: 'strength'

python,oop

That method is defined as def SetStrength(self, strength):. That means that, in addition to the self which is passed automatically, you need to provide an additional argument - in this case, the new strength value you'd like to set. It works very similarly to setName, which you call with an argument on the previous line. That said, the code you're working with is Java/C++/etc. code translated into Python, which balloons the size of the code for no good reason.

Can Java Web Start be used to run server-side programs?

Java WebStart will install a desktop application into the cache of the client. That will run on the client not on the server, however you can easily create a webapplication as a service, i.e. on Tomcat. The webapp will be able to receive client requests, i.e. via RMI, RESTfull service or webservice, call the proprietary programm and return the results.

I have a Java application that needs to run the proprietary software PowerWorld on the server and then return output to the client side Web Start window. Is this possible? How do I go about doing this? I am using Apache Tomcat to run the server. My Java code uses Runtime.exec() to run a Python script that runs PowerWorld. I made sure that the python script, powerworld file and java app are all in the same directory and reference each other using relative file paths

If you are using the runserver command, you will see the output of print-statements in that command prompt, like a live logging.

I'm a near-total newbie to Django, and am trying to debug a piece of code which is returning a null list to a template even though it should be returning a list with items in it. Is there any way to print the list to the console from within views.py for debugging purposes? I obviously can't run python views.py as the info I want is stored in a SQLite database, but if I try to include a print statement within the view I'm using, nothing prints when I refresh the page (and the server contacts my code). Is there a solution? I've looked around for a long time and can't find anything.

Require the user to change their password on first login?

In short, yes. You need to know which users need to change their password. If you don't want to use a custom User model, I would recommend having another model to store the users that need to change their password. You would add the users to this table upon user registration/creation. Then you could write a very simple middleware to check the current logged user (place it after AuthenticationMiddleware in your settings.py). If the user is flagged as requiring a password change, you could force a HttpResponse (in the middleware) to a custom view with a PasswordChangeForm (which comes out of the box in Django, in django.contrib.auth.forms.PasswordChangeForm), after which you could remove the flag to the user, and redirect them to the home page.

Selenium is really designed to be an external control system for a web browser. I don't think of it as being the source of test data, itself. There are other unit-testing frameworks which are designed for this purpose, but I see Selenium's intended purpose to be different.

You could use different settings files, let's say settings_client_1.py and settings_client_2.py, import common settings from a common settings.py file to keep it DRY. Then add respective database settings. Do the same with wsgi files, create one for each settings. Say, wsgi_c1.py and wsgi_c2.py Then, in your web server direct the requests for client1.djangoapp.com to wsgi_c1.py and client2.djangoapp.com to wsgi_c2.py

I'm hoping to be pointed in the right direction as far as what tools to use while in the process of developing an application that runs on two servers per client. [Main Server][Client db Server] Each client has their own server which has a django application managing their respective data, in addition to serving as a simple front end. The main application server has a more feature-rich front end, using the same models/db schemas. It should have full read/write access to the client's database server. The final desired effect would be a typical SaaS type deal: client1.djangoapp.com => Connects to mysql database @ client1_IP client2.djangoapp.com => Connects to mysql database @ client2_IP... Thanks in advance!
