I had the same error. Running scrapy in a virtual environment solved it. Create a virtual env : python3 -m venv env Activate your env : source env/bin/activate Install Scrapy with pip : pip install scrapy Start your crawler : scrapy crawl your_project_name_here For example my project name was kitten, I just did the following in step 4 scrapy crawl kitten NOTE: I did this on Mac OS running Python 3+

Now in order to to run my server on port80 I need to use "sudo" which does not execute in the context of the virtual environment, raising errors (i.e no module named django ...) Is there a way to get "sudo" to execute in the context of the python virtual environment?!

Coookies are your answer. They will work for any URL for the same browser. assuming your user has agreed to use them. An alternative would be to tag the links with parameters, but that is specific to the link and could be shared with others.

Load data on startup

It seems that what I am looking for doesn't exist. Django trusts the user to deal with migrations and such and doesn't check the database on load. So there is no place in the system where you can load some data on system start and be sure that you can actually load it. What I ended up doing is loading the data in ready(), but do a sanity check first by doing MyModel.objects.exist() in a try: except: block and returning if there was an exception. This is not ideal, but I haven't found any other way.

I have a file with a bunch of data common between several projects. The data needs to be loaded into the Django database. The file doesn't change that much, so loading it once on server start is sufficient. Since the file is shared between multiple projects, I do not have full control over the format, so I cannot convert this into a fixture or something. I tried loading it in ready(), but then I run into a problem when creating a new database or migrating an existing database, since apparently ready() is called before migrations are complete and I get errors from using models that do not have underlying tables. I tried to set it in class_prepared signal handler, but the loading process uses more than one model, so I cannot really be sure all required model classes are prepared. Also it seems that ready() is not called when running tests, so unit tests fail because the data is missing. What is the right place to do something like this?

I assume that your models look something like this class Contest(Model): ... something ... class Picture(Model): user = ForeignKey(User) contest = ForeignKey(Contest) ... something ... So, Picture.objects.filter(user=user) gives you pictures by a particular user (don't have to specify _id, filters operate on model objects just fine). And to get contests with pictures by a particular user you can do pics_by_user = Picture.objects.filter(user=user) contests_by_user = Contest.objects.filter(id__in=pics_by_user.values_list('contest', flat=True)) There might be an easier way though

User Signup is a standard feature provided by Odoo, and it seems that you already found it. The database selector shows because you have several PostgresSSQL databases. The easiest way is to set a filter that limits it to the one you want: start the server with the option --dbfilter=^MYDB$, where MYDBis the database name. User data is stored both in res.userand res.partner: the user specific data, such as login and password, are stored in res.user. Other data, such as the Name is stored in a related res.partner record.

From the documentation: When a user attempts to authenticate, a connection is made to the LDAP server, and the application attempts to bind using the provided username and password. If the bind attempt is successful, the user details are loaded from the LDAP server and saved in a local Django User model. The local model is only created once, and the details will be kept updated with the LDAP record details on every login. It authenticates by binding each time, and updates the information from LDAP (as you have it configured) each time. The Django user won't be removed from Django's user table if removed from LDAP; if you set multiple auth backends to also using the Django default auth, the user should be able to login (perhaps after a password reset) if removed from LDAP. If you look in your auth_user table you will noticed users using Django auth have their passwords hashed with pbkdf2_sha256, and the LDAP users passwords do not.

I am using django-python3-ldap for LDAP authentication in Django. This works completely fine but whenever an LDAP user is (successfully) authenticated the user details are stored in the local Django database (auth_user table). My question now is when the same (LDAP) user tries to authenticate next time, the user will be authenticated by LDAP or by the default Django authentication (since the user details are now stored in the local Django database)? If the user is authenticated using local Django database then the user can still able to get access even after the user is removed from the LDAP server? This is a real concern for me?. If this is the case is there a way, so that the LDAP user details is removed from the database (auth_user table) everytime the user is logged out and created every time the user is logged in?. Any help in the right direction is highly appreciated. Thank you for your valuable inputs.

Are "dummy URLs" required to make function calls to Flask from the front-end?

python,flask

As others mentioned, you can secure the endpoint so that a user has to provide credentials to issue a successful request to that endpoint. In addition, your endpoint should be using proper HTTP semantics if its creating / updating data. i.e. POST to create a drink, PUT to update a drink. This will also protect you from someone just putting the URL into a browser since that is a GET request. TL;DR Secure the endpoint (if possible) Add checks that the proper request body is provided Use proper HTTP semantics

I am making my first web app with Flask wherein a database of drinks is displayed on the front-end based on selected ingredients. Then the user selects a drink and an in-page pop-up appears with some drink info and a button "make", when the user hits "make" it calls some python code on the back end (Flask) to control GPIO on my raspberry pi to control some pumps. Does this "make" need to call some route (e.g. /make/<drink>) in order to call the python function on the back end? I don't like the idea that any user could just enter the URL (example.com/make/<drink>) where is something in the database to force the machine to make the drink even if the proper ingredients are not loaded. Even if I did checking on the back end to ensure the user had selected ingredients were loaded, I want the user to have to user the interface instead of just entering URLs. Is there a way so that the make button calls the python code without using a "dummy URL" for routing the button to the server?

Faster Google App Engine Managed VM deploys (Python compat env)?

Well, in general, 10 minute deployment isn't that bad. I use AWS Elastic Beanstalk and it's about the same for a full deployment of a production environment. However, this is totally unacceptable for your everyday development. Since you use docker, I really don't understand, why not to spin up the same container on your local machine and test it locally before releasing to staging? If that is not an option, for some reason, my second bet would be updating code directly inside the container. I've used that trick a lot. As Python a dynamic language, all you need just a fresh copy of your repo, so, you can ssh into your container and check out the code. That said, the feedback loop will be reduced to the time of committing and checking out the code. Additionally, if you set up some hooks on commit, you don't even need to check out the code manually. All in all, this is just my two cents and it would be nice to hear more opinions on that really important issue.

We're using Google App Engine (GAE) with Managed VMs for a Python compat environment, and deployments take too much time. I haven't done strict calculations, but I'm sure each deployment takes over 10 mins. What can we do to accelerate this? Is this more a GAE or a Docker issue? Haven't tried deploying Docker in other platforms so I'm not sure standard/acceptable deployment times. Having to wait so much to test an app in the staging servers damages our productivity quite a bit. Any help is appreciated. :)

If you have only a handful of reoccurring descriptive dates, the easiest thing to do would be to create a dictionary that can translate them to the explicit dates you want whenever they pop up in your data. If you have arbitrary descriptive dates or a large number of them, however, it seems that, as was discussed in the comments, NLP is the way to go.

I have some data that has descriptive dates (e.g., Monday before Thanksgiving, Last day in February, 4th Saturday in April) as part of describing start and end times. Some of the dates are explicit (e.g., October 31st). I want to store the descriptive and the explicit values so for any year I can then calculate when the exact dates are. I did some searching and came up short. This feels like a common thing, and someone must have solved it. I'm also curious if these kinds of descriptive dates have a proper name. As in the tags, my app uses Python + Django. Thanks!

Heroku SQLAlchemy database does not exist

Old question, but the answer seems to be that database_exists and create_database have special case code for when the engine URL starts with postgresql, but if the URL starts with just postgres, these functions will fail. However, SQLAlchemy in general works fine with both variants. So the solution is to make sure the database URL starts with postgresql:// and not postgres://.

Is it acceptable to use two includes for the same base url routing schema? e.g. - I have allauth installed which uses r'^accounts/', include('allauth.urls') and I want to extend this further with my own app, which extends the allauth urls even further. An example of this would be accounts/profile or some other extension of the base accounts/ url. Is it fine to do the following? r'^accounts/', include('myapp.urls') In additon to: r'^accounts/', include('allauth.urls') As far as I can tell both will just be included with the base url routing schema and it will just look for the allauth urls first?

Suppose that I have django models such A ->B ->C ->D in the default database. C is a foreign key in D,similarly B in C and C in A. On the deletion of the object A,the default behaviour of Django is that all the objects related to A directly or indirectly will get deleted automatically(On delete cascade).Thus, B,C,D would get automatically deleted. I want to implement deletion in a way such that on deletion of an object of A it would get moved to another database named 'del'.Also along with it all other related objects of B,C,D will also get moved. Is there an easy way of implementing this in one go?

Is there a way to load video files via Django but them serve them using a different server? You should define what you mean by "different server". but I assume, you mean different project that is not written in Django. Since video files land in file system ( if you design so), you can access them as you want if different project is running on the same server. otherwise you would need some file sync between servers. if you want to distinguish which video file belongs to which object in db, I would insert the object name into filepath. if I didnot fully answer your question, let me know below

In your case, I think the better is to put your two models in one app.

Recently I've been making a few test projects in Django and while I've found the structure to be better than that of other Web Frameworks, I am a little confused on the concept of different 'apps'. Here is a test case example: Suppose I have a simple CRUD application where users post a picture and a title, with a small description, but I want other users to have the ability to create a review of this picture. Seeing as both the "Post" and "Review" models in this case require CRUD functionality, would I just have two models in the same app, and associate them with one another? Or have two separate apps with different urls.py and views.py files? I have a hunch I've been doing it wrong and it should be just two models, if this is the case how would I go about writing the urls and views for two models in the same app? Thanks and any input is appreciated!

If you wanna set this for all website users you need to set them to portal users. Also, you can set under Users->Preferences->Home Action set to Website. UPDATE For signup new users you need to create template user account and check portal options for that user. Next, go to Settings->General Settings under Portal Access find Template user for new users created through signup choose your template user.

Using CodeDeploy ValidateService Hook with Python Application

I would loop in the ValidateService hook, checking for the condition you expect, OR just sleep for 60 seconds, assuming that is the normal initialization time. The ValidateService hook should do just that: make sure the service is fully running before continuing/finalizing the deployment. That depends on your app of course. But consider a loop that pulls a specially designed page EG http://localhost/service-ready. In that URL, test and confirm anything and everything appropriate for your service. Return a -Pending- string if the service is not yet validated. Return a -OK- when everything is 100% Perhaps loop that 10-20 times with a 10 second sleep, and exit when it returns -OK- then throw an error if the service never validates.

I have an heavy app hosted on AWS. I use CodeDeploy & Code Pipeline (updating from github) to update the servers when a new release is ready (currently running 6 ec2 instances on production environment). I've setup the codedeploy to operate one-by-one and also defined a 300 seconds connection draining on the load balancer. Still, my application is heavy (it loads large dictionary pickle files from the disk to the memory), the process of firing up takes about ~60 seconds. In those 60 seconds CodeDeploy marks the process of deployment to an instance as completed, causing it to join back as a healthy instance to the load balancer - this might cause errors to users trying to reach the application. I thought about using the ValidateService hook, but i'm not sure how to in my case.. Any ideas on how to wait for a full load and readyness of the application before proceeding to the next instance? This is my current AppSpec.yml version: 0.0 os: linux files: - source: /deployment destination: /deployment - source: /webserver/src destination: /vagrant/webserver/src permissions: - object: /deployment pattern: "**" owner: root mode: 644 type: - directory - object: /webserver/src owner: root mode: 644 except: [/webserver/src/dictionaries] type: - directory hooks: ApplicationStop: - location: /deployment/aws_application_stop.sh BeforeInstall: - location: /deployment/aws_before_install.sh AfterInstall: - location: /deployment/aws_after_install.sh ApplicationStart: - location: /deployment/aws_application_start.sh

So I have a neural network in tensorflow (python2.7) and I need to retrieve its output using Java. I have a simple python function getValue(input) which starts the session and retrieves the value. I am open to any suggestions. I believe Jython wont work cause tensorflow is not in the library. I need the call to be as fast as possible. JNI exists for Java calling C so can I convert with cython and compile then use JNI? Is there a way to pass the information in RAM or some other way I haven't thought of?

The two locations are separate origins in HTTP language. By default, they should not share cookies. Before trying to figure out how to pass cookies around I'd try to set up a front end web server like Nginx that would proxy requests between two different backend servers. Both applications could get their own path, served from www.abcd.com.

In a server, I have a pyramid app running and I plan to have another tornado app running in parallel in the same machine. Let's say the pyramid app is available in www.abcd.com, then the tornado app will be available in www.abcd.com:9000. I want only the authenticated users in the pyramid webapp to be able to access the tornado webapp. My guess is somehow using cookie set by the pyramid app in tornado. Is it possible? What is the best way to do that?

Handling time consuming requests in Flask-UWSGI app

As an option you can do the following: Separate the heavy logic from the function which is being called upon @route and move it into a separate place (a file, another function, etc) Introduce Celery to run that pieces of heavy logic (it will be processed in a separate thread from the @route-decorated functions). A quick way of doing this is using Redis as a message broker. Schedule the time-consuming functions from your @route-decorated functions in Celery (it is possible to pass parameters as well) This way the HTTP requests won't be blocked for the complete function execution time.

Am running an app with Flask , UWSGI and Nginx. My UWSGI is set to spawn out 4 parallel processes to handle multiple requests at the same time. Now I have one request that takes lot of time and that changes important data concerning the application. So, when one UWSGI process is processing that request and say all others are also busy, the fifth request would have to wait. The problem here is I cannot change this request to run in an offline mode as it changes important data and the user cannot simply remain unknown about it. What is the best way to handle this situation ?

After so many struggle I found one solution, want to share it with you. Hope you will like it. open <your python location>\Lib\site-packages\django\core\management\commands\runserver.py and find one code where it deal with self.addr. if not self.addr: self.addr = '::1' if self.use_ipv6 else '127.0.0.1' It sets default address to 127.0.0.1 change it to '0.0.0.0'. Now, if you run your server with only command ./manage.py runserver It will run on 0.0.0.0, even from visual studio. Good luck.

I can access it from other origin when I run it through command prompt as python manage.py runserver 0.0.0.0:8086. But, in visual studio auto debug, it runs on 127.0.0.0. I want to configure visual studio to run the server on specified ip (ie. 0.0.0.0). So, that debugging will be easy. I have tried with setting default port and address from site-packages\django\core\management\commands\runserver.py. and also able to set default port in visual studio property of the project. But, unable to set the default ip. Can any one help me to configure the ip 0.0.0.0 as default not the default one (127.0.0.1) in visual studio. Thanks in advance.

I am using a custom Django runserver command that is supposed to run a bunch of cleanup functions upon termination. This works fine as long as I don't use the autoreloader: by server catches the KeyboardInterrupt exception properly and exits gracefully. However, if I use Django's autoreloader, the reloader seems to simply kill the server thread without properly terminating it (as far as I can tell, it doesn't have any means to do this). This seems inherently unsafe, so I can't really believe that there's not a better way of handling this. Can I somehow use the autoreloader functionality without having my server thread be killed uncleanly?

Python in Knime: Downloading files and dynamically pressing them into workflow

There are multiple options to let things work: Convert the files in-memory to a Binary Object cells using Python, later you can use that in KNIME. (This one, I am not sure is supported, but as I remember it was demoed in one of the last KNIME gatherings.) Save the files to a temporary folder (Create Temp Dir) using Python and connect the Pyhon node using a flow variable connection to a file reader node in KNIME (which should work in a loop: List Files, check the Iterate List of Files metanode). Maybe there is already S3 Remote File Handling support in KNIME, so you can do the downloading, unzipping within KNIME. (Not that I know of, but it would be nice.) I would go with option 2, but I am not so familiar with Python, so for you, probably option 1 is the best. (In case option 3 is supported, that is the best in my opinion.)

I'm using Knime 3.1.2 on OSX and Linux for OPENMS analysis (Mass Spectrometry). Currently, it uses static filename.mzML files manually put in a directory. It usually has more than one file pressed in at a time ('Input FileS' module not 'Input File' module) using a ZipLoopStart. I want these files to be downloaded dynamically and then pressed into the workflow...but I'm not sure the best way to do that. Currently, I have a Python script that downloads .gz files (from AWS S3) and then unzips them. I already have variations that can unzip the files into memory using StringIO (and maybe pass them into the workflow from there as data??). It can also download them to a directory...which maybe can them be used as the source? But I don't know how to tell the ZipLoop to wait and check the directory after the python script is run. I also could have the python script run as a separate entity (outside of knime) and then, once the directory is populated, call knime...HOWEVER there will always be a different number of files (maybe 1, maybe three)...and I don't know how to make the 'Input Files' knime node to handle an unknown number of input files. I hope this makes sense. Thanks!

So I've been working on scraper that goes on 10k+pages and scrapes data from it. The issue is that over time, memory consumption raises drastically. So to overcome this - instead of closing driver instance only at the end of scrape - the scraper is updated so that it closes the instance after every page is loaded and data extracted. But ram memory still gets populated for some reason. I tried using PhantomJS but it doesn't load data properly for some reason. I also tried with the initial version of the scraper to limit cache in Firefox to 100mb, but that also did not work. Note: I run tests with both chromedriver and firefox, and unfortunately I can't use libraries such as requests, mechanize, etc... instead of selenium. Any help is appreciated since I've been trying to figure this out for a week now. Thanks.

Are you trying to say that your drivers are what's filling up your memory? How are you closing them? If you're extracting your data, do you still have references to some collection that's storing them in memory? You mentioned that you were already running out of memory when you closed the driver instance at the end of scraping, which makes it seem like you're keeping extra references.

Check your is_active model field. You may have set its default value to False, hence the reason it might not let you log in. If it's like this -- is_active = models.BooleanField(default=False) -- change it to True, or inspect the database and change the value in is_active for the created superuser to 1.

I have to find a solution for sharing code between two big Django projects. The main things to share are models and serializers and template tags. I've came up with 3 different solutions and I need you to find pro and cons to be able to make a choice. I'll list you the solutions I found: git submodules Create a repository where to store my *.py files and include them as a django app such as 'common_deps' Even if this is the purpose of git submodules there are a bit hard to use and its easy to fall into traps. python package Create a python package to store my *.py files. It seems to be the best option to me event if that means that I'll need to change my requirements.txt file on my projects on each new release. Simple git repository Create a new repository to store my *.py files and include them as a django app such as 'common_deps'. Then add it to my PYTHON_PATH I need some advices, I haven't chosen yet. I'm just telling myself that git submodules seems to be a bas idea. Tell me guys.

I am trying to set up Oauth2 with the Mailchimp API. So far things seem to be working correctly except that after having the user login at Mailchimp, the browser doesn't redirect back to my redirect_uri. It just stays on the Mailchimp login page. For the code: I redirect the user to the authorize url/mailchimp login: authorize_uri = 'https://login.mailchimp.com/oauth2/authorize? response_type=code&client_id=%s&client_secret=%s&redirect_uri=%s' % (settings.MAILCHIMP_CLIENT_ID, settings.MAILCHIMP_CLIENT_SECRET, redirect_uri) my redirect_uri is redirect_uri = 'http://127.0.0.1:8000/mailchimp/connect' So the authorize_url redirects to the login page, and I login with credentials that absolutely work to login the regular non-oauth way. Also I see the 302 redirect with the code I need in my logs, but the browser seems to just refresh the Mailchimp login page and the view(I'm using django) for processing the GET request below is never triggered. [06/Jul/2016 02:31:43] "GET /mailchimp/connect?code=36ad22daa3d0f8b3804f7e340e5d50f1 HTTP/1.1" 302 0 I have no idea what I'm doing wrong...

For example: /usr/local/lib/python2.7/dist-packages/scrapy. For example if it is at '/PATH/TO/SCRAPY', run this command on the terminal: sudo rm -rf /PATH/TO/SCRAPY

The first approach I'd try would be to check out the last good commit and recreate the model changes in question so the migration could be regenerated and checked in. And while it's good to have a contingency plan for things like this, if it's a real concern I'd suggest evaluating your deployment process to make this issue less likely.

I need to setup a Heroku app (python) which would perform scheduled tasks that include fetching a set of data (.csv an .html) files from other Heroku app (ROR) and returning a result back to that app. Also it should be restricted only to my app to be able to connect to the ROR app because it deals with sensitive information. There would be from 20 to 100 files each time so I want them to be compressed somehow to transfer them quiclky (to avoid bothering the server for too long). I'm interested in possible ways to accomplish it. The first thought is to send HTTP GET request to the ROR app and fetch the necessary files yet it generally not secured at all. Would SCP work in some way in this situation or you have any other ideas? Thanks in advance!

How to save spaCy model onto cache?

python,caching,spacy

First of all you, if you only do NER, you can install the parser without vectors. This is possible giving the argument parser to: python -m spacy.en.download parser This will prevent the 700MB+ Glove vectors to be downloaded, slimming the memory needed for a single run. Then, well, it depends on your application/usage you make of the library. If you call it often it will be better to pass spacy.load('en') to a module/class variable loaded at the beginning of your stack. This will slow down a bit your boot time, but spacy will be ready (in memory) to be called. (If the boot time is a big problem, you can do lazy loading).

The {{ form }} statement is relative to Django template. Django templates responsible for rendering HTML and so do React, so you don't have to mix the two together. What you probably want to do is to use the Django form validation mechanism server side, let React render the form client-side. In your Django view, simply return a JSON object that you can use in your React code to initialize your form component.

Ideally you don't even need to clicks buttons in these kind of cases. All you need is to see at what webservice does the form sends request when clicked on submit button. For that open your developer's control in the browser, Go to the Network tab and select 'preserve log'. Now submit the form manually and look for the first xhr GET/POST request sent. It would be POST request 90% of times. Now when you select that request in the request parameters it would show the values that you entered while submitting the form. Bingo!! Now all you need to do is mimic this request with relevant request headers and parameters in your python code using requests. And Wooshh!! Hope it helps..

I am trying to embed the exact form that appears in the Django admin when I edit a model in a different page on my website. My plan is to have an Edit button that, when clicked, displays a modal with the edit page inside of it. The issue with using a ModelForm is that this particular model has two generic foreign keys. The admin handles this perfectly, providing the ability to add, edit, or remove these objects. If I could embed the admin page (with its HTML or perhaps my own), that would be all I need. Thanks!

required field difference in python file and xml file

38,368,546

0

227

python,openerp

The difference is that in the python .py when you set a fields required argument to True, it's creates a NOT NULL constraint directly on the database, this means that no matter what happens (Provided data didn't already exist in the table) you can never insert data into that table without that field containing a value, if you try to do so directly from psql or Odoo's xmlrpc or jsonrpc api you'll get an SQL NOT NULL error, with something like this `ERROR: null value in column "xxx" violates not-null constraint On the other-hand if you set a field to be required on the view (xml) then no constraint is set on the database, this means that the only restriction is the view and you can bypass that and write to the database directly or if you're making an external web service you can use Odoo's ORM methods to write to the database directly If you really want to make sure a column is not null and is required, then it's better to set that in the python code itself instead of the view.

If you don't have any important data in your test or production databases your can use fresh initial migration and it will be appropriate solution. I've used this trick a lot of times and it works for me. A few thoughts: sometimes, first you need to create migrations for one of your local application and then for all the others; to be sure that all be ok you can commit your migrations and backup you db before you run ./migrate with empty db. NOTE: to speed up your tests you can try to run in memory tests and/or run tests with sqlite if its possible.

I have an app with 35 migrations which take a while to run (for instance before tests), so I would like to squash them. The squashmigrations command reduces the operations from 99 to 88, but it is still far from optimal. This is probably due to the fact that I have multiple RunPython operations preventing Django from optimizing other operations. All these RunPython operations are useless in the squashed migration because the database is empty. In Django 1.10 the elidable parameter will allow to skip them in this case, but still, a lot of clutter remains. What I had in mind for the squashed migration was closer to the initial migrations Django generates, hence my question: Is it advisable to use a fresh initial migration as a squashed version of a long list of migrations? How would you do that?

I can suggest a way to handle that situation but I'm not sure how much will it suit for your scenario. Since you are trying to use a wifi network, I think it would be better if you can use a sql server to store commands you need to give to the vehicle to follow from the web interface sequentially. Make the vehicle to read the database to check whether there are new commands to be executed, if there are, execute sequentially. From that way you can divide the work into two parts and handle the project easily. Handling user inputs via web interface to control vehicle. Then make the vehicle read the requests and execute them. Hope this will help you in someway. Cheers!

For a college project I'm tasked with getting a Raspberry Pi to control an RC car over WiFi, the best way to do this would be through a web interface for the sake of accessibility (one of the key reqs for the module). However I keep hitting walls, I can make a python script control the car, however doing this through a web interface has proven to be dificult to say the least. I'm using an Adafruit PWM Pi Hat to control the servo and ESC within the RC car and it only has python libraries as far as I'm aware so it has to be witihn python. If there is some method of passing variables from javascript to python that may work, but in a live environment I don't know how reliable it would be. Any help on the matter would prove most valuable, thanks in advance.

Ethics Using a bot to get at the content of sites can be beneficial to you and the site you're scraping. You can use the data to refer to content of the site, like search engines do. Sometimes you might want to provide a service to user that the original website doesn't offer. However, sometimes scraping is used for nefarious purposes. Stealing content, using the computer resources of others, or worse. It is not clear what intention you have. Helping you, might be unethical. I'm not saying it is, but it could be. I don't understand 'AucT', saying it is bad practice and then give an answer. What is that all about? Two notes: Search results take more resources to generate than most other webpages. They are especially vulnerable to denial-of-service attacks. I run serveral sites, and I have notices that a large amount of traffic is caused by bots. It is literally costing me money. Some sites have more traffic from bots than from people. It is getting out of hand, and I had to invest quite a bit of time to get the problem under control. Bots that don't respect bandwidth limits are blocked by me, permanently. I do, of course, allow friendly bots.

I recommend you to pass a parameter like login/?next=pageA.html If the login fails, you could then forward your parameter next to /login again, even if the referrer points now to /login. Then when the user will successfully log in, you could redirect if to pageA.html that will be held in your next parameter. You will indeed need to check if your parameter next is a valid one, as someone could copy-paste or try to tamper with this parameter.

I'm adding authentication to an existing pyramid project. The simplest form that I'm currently trying (will be expending later) is for all pages to raise HTTPForbidden. The exception view is /login, which will ask for login details and, on success, return HTTPFound with request.referer as the location. So far so good, this does what I want, which is bringing users back to the page they were trying to access when the login page interrupted them. Let's call this Page A. The login page is a simple HTML form with a submit button. However if the user mistypes username or password, I want to return to the login page with an error message saying "Wrong password" or similar. When that happens, request.referer is now the login page instead of Page A. How do I 'store' Page A (or rather its URL) so that, when the user eventually succeeds in logging in, they find themselves back on Page A? Is the session used for things like this, and are there non-session ways of implementing it? I don't (yet) have a session for this simple page, and am trying to avoid adding different components in one pass.

If you are using only javascript and don't feel like a framework is the solution, you'd better rewrite your python script using javascript. These two languages have a lot in common and most of the stuff are transferable. Calling python from javascript would most likely not going to work that great. Again, unless you share your python script(which is encouraged in SO because text only question does not quite fit in here), all answers are opinion based.

I'm wondering if there's a good way for me to incorporate Python scripts into my current website. I have a personal website & my own server that I have been working with for a while. So far it's just been html / css / javascript. I have made a Python script in the past that uses another website's API to retrieve something that I would like to display on my website. I've only used Python from the terminal to take input and spit out results. Is there a way for me to run a Python script from javascript through Ajax to get some content back? I don't really want to use a framework like Django or Flask because I feel as though those are mostly for entire projects. I only want to use one Python script on one page for my website. Is this even something I should do? Any advice would be great.

I completly agree with you about Django, but I think you can give a chance to Flask, it is really light and I can be used for many porpouses. Anyway if you want to call a python scripts you need a way to call it. I think you need a "listener" for the script for example a service or a web service (for this reason I think Flask can be an really easy solution). Be careful about calling the script, a web service can be reachable from the frontend but this can not be done from a "standard" script. My suggestion is take a look at Flask is more light that you think.

I'm wondering if there's a good way for me to incorporate Python scripts into my current website. I have a personal website & my own server that I have been working with for a while. So far it's just been html / css / javascript. I have made a Python script in the past that uses another website's API to retrieve something that I would like to display on my website. I've only used Python from the terminal to take input and spit out results. Is there a way for me to run a Python script from javascript through Ajax to get some content back? I don't really want to use a framework like Django or Flask because I feel as though those are mostly for entire projects. I only want to use one Python script on one page for my website. Is this even something I should do? Any advice would be great.

How is Flask-Login's request_loader related to user_loader?

python,flask,flask-login

I need to make this clear. This is the reason why you shoud use request_loader with flask_login. There will be a lot of @login_required from flask_login used in your api to guard the request access. You need to make a request to pass the check of auth. And there will be a lot of current_user imported from flask_login, Your app need to use them to let the request act as the identity of the current_user. There are two ways to achieve the above with flask_login. Using user_loader makes the request to be OK for @login_required. It is often used for UI logins from browser. It will store session cookies to the browser and use them to auth later. So you need to login only once and the session will keep for a time. Using request_loader will also be OK with @login_required. But it is often used with api_key or basic auth. For example used by other apps to interact with your flask app. There will be no session cookies, so you need to provide the auth info every time you send request. With both user_loader and request_loader, now you got 2 ways of auth for the same api, protected by @login_required, and with current_user usable, which is really smart.

I apologize in advance for asking a rather cryptic question. However, I did not understand it despite going through a lot of material. It would be great if you could shed some light on this. What is the purpose of a request_loader in flask-login? How does it interact with the user_loader decorator? If I am using a token based authentication system (I am planning on sending the token to my angularJS front end, storing the token there and sending that token in the authorization-token header), will I need a request_loader or will a user_loader (where I check the auth header and see if the user exists) suffice?

I think the best if you run Errbot in a container is to run it with a real database for the persistence (redis for example). Then you can simply run backup.py from anywhere (including your dev machine). Even better, you can just do a backup of your redis directly.

How Do I Authenticate OneNote Without Opening Browser?

If this is always with the same account - you can make the "browser opening and password typing" a one time setup process. Once you've authenticated, you have the "access token" and the "refresh token". You can keep using the access token for ~1hr. Once it expires, you can use the "refresh token" to exchange it for an "access token" without any user interaction. You should always keep the refresh token so you can get new access tokens later. This is how "background" apps like "IFTTT" keep access to your account for a longer period of time. Answer to your updated question: The initial setup has to be through UI in a browser. If you want to automate this, you'll have to write some UI automation.

I want to create a python script that will allow me to upload files to OneNote via command line. I have it working perfectly and it authenticates fine. However, everytime it goes to authenticate, it has to open a browser window. (This is because authentication tokens only last an hour with OneNote, and it has to use a refresh token to get a new one.) While I don't have to interact with the browser window at all, the fact that it needs to open one is problematic because the program has to run exclusively in a terminal environment. (E.g. the OneNote authentication code tries to open a browser, but it can't because there isn't a browser to open). How can I get around this problem? Please assume it's not possible to change the environment setup. UPDATE: You have to get a code in order to generate an access token. This is the part that launches the browser. It is only required the first time though, for that initial token. Afterwards, refresh token requests don't need the code. (I was calling it for both, which was the issue). That solves the problem of the browser opening each time I run my program. However, it still leaves the problem of the browser having to open that initial time. I can't do that in a terminal environment. Is there a way around that? E.g. Can I save the code and call it later to get the access token (how long until it expires)? Will the code work for any user, or will it only work for me?

Ok, have a class based view that passes a query_set into my AssignedToMe class. The point of this class based view is to see if a user is logged in and if they are, they can go to a page and it will display all of records that are assigned to their ID. Currently, it is working how I want it to but only if a user is logged in. If a user is not logged in, I get the following error 'AnonymousUser' object is not iterable. I want it to redirect the user to the login page if there is no user logged in. Thank you in advance. Please look at the screenshot

We have implemented a simple DynamoDB database that is updated by a remote IoT device that does not have a user (i.e. root) constantly logged in to the device. We have experience issues in logging data as the database is not updated if a user (i.e. root) is not logged into the device (we log in via a ssh session). We are confident that the process is running in the background as we are using a Linux service that runs on bootup to execute a script. We have verified that the script runs on bootup and successfully pushes data to Dynamo upon user log in (via ssh). We have also tried to disassociate a screen session to allow for the device to publish data to Dynamo but this did not seem to fix the issue. Has anyone else experienced this issue? Does amazon AWS require a user (i.e. root) to be logged in to the device at all times in order to allow for data to be published to AWS?

You need some kind of mutex. Since your operations involve the filesystem already, perhaps you could use a file as a mutex. For instance, at the start of the operation, check if a specific file exists in a specific place; if it does, return an error, but if not, create it and proceed, deleting it at the end of the operation (making sure to also delete it in the case of any error).

I'm usually a huge proponent for DRF. It's simple to implement an easy use case, yet INCREDIBLY powerful for more complex uses. However, if you are not using Django models for all your data, I think JsonResponse might be easier. Running queries and manual manipulation (especially if it is only a single endpoint) might be the way to go. Sorry for not weighing in on the other part of the question.

I’m currently working on improving a Django project that is used internally at my company. The project is growing quickly so I’m trying to make some design choices now before it’s unmanageable to refactor. Right now the project has a two really important models the rest of the data in the database that supports the each application in the project is added into the database through various separate ETL processes. Because of this the majority of data used in the application is queried in each view via SQLAlchemy using a straight up multiline string and passing the data through to the view via the context param when rendering rather than using the Django ORM. Would there be a distinct advantage in building models for all the tables that are populated via ETL processes so I can start using the Django ORM vs using SQLAlchemy and query strings? I think it also makes sense to start building an API rather than passing a gigantic amount of information through to a single view via the context param, but I’m unsure of how to structure the API. I’ve read that some people create an entirely separate app named API and make all the views in it return a JsonResponse. I’ve also read others do this same view based API but they simply include an api.py file in each application in their Django project. Others use the Django REST API Framework, which seems simple but is slightly more complicated than just returning JsonResponse via a view. There is really only one place where a users interaction does anything but GET data from the database and that portion of the project uses Django REST Framework to perform CRUD operations. That being said: Which of these API structures is the most typical, and what do I gain/lose by implementing JsonResponse views as an API vs using the Django REST Framework? Thanks you in advance for any resources or advice anyone has regarding these questions. Please let me know if I can add any additional context.

Would there be a distinct advantage in building models for all the tables that are populated via ETL processes so I can start using the Django ORM vs using SQLAlchemy and query strings? Yes, a centralized, consistent way of accessing the data, and of course, one less dependency on the project. Which of these API structures is the most typical, and what do I gain/lose by implementing JsonResponse views as an API vs using the Django REST Framework? In general terms, JSON is used for data, and REST for APIs. You mentioned that Django-REST is already in use, so if there's any tangible benefit from having a REST API, I'd go with it

Storing entries in a very large database

python,django,database,postgresql,saas

Store one at a time until you absolutely cannot anymore, then design something else around your specific problem. SQL is a declarative language, meaning "give me all records matching X" doesn't tell the db server how to do this. Consequently, you have a lot of ways to help the db server do this quickly even when you have hundreds of millions of records. Additionally RDBMSs are optimized for this problem over a lot of years of experience so to a certain point, you will not beat a system like PostgreSQL. So as they say, premature optimization is the root of all evil. So let's look at two ways PostgreSQL might go through a table to give you the results. The first is a sequential scan, where it iterates over a series of pages, scans each page for the values and returns the records to you. This works better than any other method for very small tables. It is slow on large tables. Complexity is O(n) where n is the size of the table, for any number of records. So a second approach might be an index scan. Here PostgreSQL traverses a series of pages in a b-tree index to find the records. Complexity is O(log(n)) to find each record. Internally PostgreSQL stores the rows in batches with fixed sizes, as pages. It already solves this problem for you. If you try to do the same, then you have batches of records inside batches of records, which is usually a recipe for bad things.

I am writing a Django application that will have entries entered by users of the site. Now suppose that everything goes well, and I get the expected number of visitors (unlikely, but I'm planning for the future). This would result in hundreds of millions of entries in a single PostgreSQL database. As iterating through such a large number of entries and checking their values is not a good idea, I am considering ways of grouping entries together. Is grouping entries in to sets of (let's say) 100 a better idea for storing this many entries? Or is there a better way that I could optimize this?

I'm trying to read from a Google sheet say every 2 hours. I have looked at both the API for Google sheets and also the Google Apps Script. I'm using Python/Flask, and what I'm specifically confused about is how to add the time trigger. I can use the Google Sheets API to read from the actual file,but I'm unsure of how to run this process every x hours. From my understanding, it seems like Google Apps Script, is for adding triggers to doc, sheets, etc, which is not really what I want to do. I'm pretty sure I'm looking in the wrong area for this x hour read. Should I be looking into using the sched module or Advanced Python Scheduler?Any advice on how to proceed would be very appreciated.

How can I run Deep Dream on Android

Short answer is no. Google deepdream is an iPython notebook with dependencies on caffe which itself has several dependencies. There is however no reason why someone couldn't develop a similar tool for Android. There is an app called dreamscope for producing these kinds of images that is available for android, but I would presume they do all of their image computation in the cloud.

I am trying to speed up my website. So at the moment, controller fetches data from database, do calculation on data and display on view. what I plan to do is, controller/action fetches half the data and display to the view. Than come back to different controller/action and do calculation on data and display data on screen. But what I want to know is once I fetch data and display on screen, how do I go back to controller automatically(without any click by user) to do calculations on same data.

How are Django channels different than celery?

Django channels gives to Django the ability to handle more than just plain HTTP requests, including Websockets and HTTP2. Think of this as 2 way duplex communication that happens asynchronously No browser refreshing. Multiple clients can send and receive data via websocket and django channels orchestrates this intercommunication example a group chat with simultaneously clients accessing at the same time. You can achieve background processing of long running code simliar to that of a celery to a certain extent, but the application of channels is different to that of celery. Celery is an asynchronous task queue/job queue based on distributed message passing. As well as scheduling. In layman's terms, I want to fire and run a task in the background or I want to have a periodical task that fires and runs in the back on a set interval. You can also fire task in a synchronous way as well fire and wait until complete and continue. So the key difference is in the use case they serve and objectives of the frameworks

Other answers, greatly explained the diff, but in facts Channels & Celery can both do asynchronous pooled tasks in common. Channels and Celery both use a backend for messages and worker daemon(s). So the same kind of thing could be implemented with both. But keep in mind that Celery is primary made for and can handle most issue of task pooling (retries, result backend, etc), where Channels is absolutely not made for.

Maven build with Java: How to execute script located in resources?

The maven path for all the artifacts is not the same that gets generated when you run it or export the project. You can check this by exporting the project as Jar/War/Ear file and viewing it via winRAR or any other tool. The resources should be in jar parallel to com directory if its a jar project, but you can double check it.

I am building my Java project with Maven and I have a script file that ends up in the target/classes/resources folder. While I can access the file itself via this.getClass.getResource("/lookUpScript.py").getPath(), I cannot execute a shell command with "." + this.getClass.getResource("/lookUpScript.py").getPath(); this ultimately ends up being ./lookUpScript.py. To execute the shell command I am using a method that is part of my company's code that I can get to work fine with any command not involving a file. Is there a standard way of accessing files located in the resources area of a Maven build that may fix this?

sending dynamic html email containing javascript via a python script

Sorry, but you'll not be able to send an email with JavaScript embedded. That is a security risk. If you're lucky, an email provider will strip it before rendering, if you're unlucky, you'll be sent directly to spam and the provider will distrust your domain. You're better off sending an email with a link to the chart.

at the first place, I could not help myself with the correct search terms on this. secondly, I couldnt pretty much make it working with standard smtplib or email package in python. The question is, I have a normal html page(basically it contains a that is generated from bokeh package in python, and all it does is generating an html page the javascript within renders a nice zoomable plot when viewed in a browser. My aim is to send that report (the html basically) over to recipients in a mail.
