There is no way to delete it from the Terminal (unfortunately), but you can delete it directly. Just log into the admin page, click on the user you want to delete, scroll down to the bottom and press delete.

This may be a duplicate, but I couldn't find the question anywhere, so I'll go ahead and ask: Is there a simple way to delete a superuser from the terminal, perhaps analogous to Django's createsuperuser command?

No need to delete superuser...just create another superuser... You can create another superuser with same name as the previous one. I have forgotten the password of the superuser so I create another superuser with the same name as previously.

Import Data Efficiently from Datastore to BigQuery every Hour - Python

There is no full working example (as far as I know), but I believe that the following process could help you : 1- You'd need to add a "last time changed" to your entities, and update it. 2- Every hour you can run a MapReduce job, where your mapper can have a filter to check for last time updated and only pick up those entities that were updated in the last hour 3- Manually add what needs to be added to your backup. As I said, this is pretty high level, but the actual answer will require a bunch of code. I don't think it is suited to Stack Overflow's format honestly.

Currently, I'm using Google's 2-step method to backup the datastore and than import it to BigQuery. I also reviewed the code using pipeline. Both methods are not efficient and have high cost since all data is imported everytime. I need only to add the records added from last import. What is the right way of doing it? Is there a working example on how to do it in python?

I made a new report on OpenERP, for stock module, which uses the product.product model, like the default one which is Stock Level Forecast. Now, what is the problem I have, I need this report to be shown on "Location Structure->Physical Locations->Warehouse->Analyze current inventory" It is showing there, no errors, everything's fine, but my problem is, because this report is tied to product.product I need to show some product fields (already declared on report) and the location_id of the warehouse I'm querying. Obviously if I loop over the current location on my report, it throws an error, because this is a stock object, and not from product. So, my question is, how can I bring all product fields into stock, to effectively report all product fields AND stock location at the same time? I guess I should make a related field, or a one2many there, but I'm very confused at this point. Any ideas? I hope I explained myself, if you need the code please let me know I'll edit my question then. Thanks in advance!

Django field that is a hybrid of text file upload and/or text box

Regardless of the method of input chosen, the data would be stored as a text column in the backing database. In that case, I would use a regular CharField. It just makes more sense. In the form, use 2 not required fields instead: key_text and key_file. Overwrite clean() to make at least one required. Then overwrite save(...).

I'm trying to see if this is possible: a Field object that is rendered as both a file upload prompt as well as a text box. Since my app deals with SSL certificates and keys, it makes sense to allow the user to either upload a key/cert file, or paste the key/cert in directly. Regardless of the method of input chosen, the data would be stored as a text column in the backing database. This would purely be for convenience's sake.

By others, do you mean someone on your local network or someone on internet. On local network its very easy, instead starting the local developmnet server by python manage.py runserver you can do python manage.py runserver 10.1.0.123:8000 (assuming 10.1.0.123 is your system's ip), then people on you local network can access http://10.1.0.123:8000 to see your site. If you want to show it to someone on internet, then either you host it on something like heroku, or another cheap and quick method if to configure your router to divert the specific port to your machine and give that person your dynamic ip. This only applies if you have a router like in a home dev setup. You can go to google and just type what is my ip and get your dynamic static ip

A bit of a beginner question.Iv just started learning Django and can pretty much create basic stuff .Now when I want to access my website on my computer I just type in the local URL and I can access the site,other links etc. If I want to show this to someone else how would I do it?..They wouldn't be able to just type in the local url so what would they need to do to access it?Also If someone asks me to create an API for them what exactly does it mean?I'm a beginner with web technologies so any help would be appreciated! Thanks.

Usually you have a webserver (Apache, nginx...) before that. Depending on the webserver and OS it can be rather easy to deactivate a site. For example Ubuntu + Apache configure a default host that returns only 503 Service Unavailable configure a site configuration with a VirtualHost with the actual WSGI setup for the webservice activate the website with a2ensite <name> and service apache2 reload activate the website with a2dissite <name> and service apache2 reload But there are very many other solutions to your problem.

i'm new in all of webservices and more webservices with python. I tested bottle, ladon, flask and django REST framework... With different opinions but all working more or less fine. Now i need to have something like a admin view to start or stop these services. Looking these frameworks i cant find anything about it. I searched here and neither. So i was looking for something like admin django view where i can start o stop a service. Which framework or technology do you recommend me? thank you.

For the exact same reasons than you used the django-admin for the admin instead of writing views, forms and templates from scratch: less work tested and approved by many other developers therefore more secured DRF has a really nice architecture. When you use it, you'd think "that's how I would have done it" (the truth is "this is how I wish I would have done it"). DRF also let you browse/test the API via HTML. 'External developers' who wants to use the data from my website on their own website? Yes For me to get a nice overview of my data (even though the admin does this job good)? Admin is better indeed for that. Use the create, read, update and delete functions in ajax calls on different pages on my website? Yes Or should all views that get data from a model get the data through an API to check permissions etc.? You don't have to get data through your API (is that what you mean?). I've never setup an application this way. That being said, you can do it, start by building an API both for you and external developers especially if you're going to use a lot of Javascript.

I have been looking at django-tastypie and django-rest-framework. What is the advantage of using an API? I've thought of following use cases. Which use cases is an API primarily intended for? 'External developers' who wants to use the data from my website on their own website? For me to get a nice overview of my data (even though the admin does this job good)? Use the create, read, update and delete functions in ajax calls on different pages on my website? Or should all views that get data from a model get the data through an API to check permissions etc.? I have read some of the documentation for both APIs but it's still not completely clear to me. Django has request.is_ajax() and Django 1.7 introduced JsonResponse so I cannot see why a big complex framework could make a better job sending and receiving json but I guess I'm wrong based on the number of developers who use the api frameworks :-D

I am trying to setup token based authentication in python. using Django/DRF. but this is more about http in general i think. When users put in username/password I return to them their token via JSON. The client then can post the token in HTTP Header for me to check. My problem is I want the token to persist in the header automatically, just like cookies. When the server says "set-cookie" to browser (Chrome/FF), the browser will automatically send up the cookie without me actually doing anything. Is there something I can do with this token? I have tried storing it in header: "Authorization", but the browser didn't return it. Is there something like "Set-Authorization"? thanks

Web application + Mobile App Python/Django architecture

android,python,django,architecture,django-rest-framework

I don't use Django but I am currently using Angular with Flask as my REST backend. I think the hybrid approach is useful if your app benefits from caching rendered content. An example would be something like a blogging site where you may store Markdown but render HTML and thus the content is largely unchanging. If this content is shared across many users it can be very beneficial to generate once on the server and serve it to many clients. However if your reasoning is that because mobiles are relatively under-powered server-side rendering will improve the render time, this does not necessarily hold true. Serving the JSON data model will typically result in less network traffic (obviously dependent on browser caching) which is important for mobile client responsiveness. For my own part I prefer to render on the client and keep the server-side rendering to some very minimal templates. I find this results in a much better REST API that I can then use to provide external developer access or plug in other client UIs. My client code lives on the client side in Angular, my REST interface is clean, and security is always uppermost in my mind because I have to assume that the client code is potentially hostile. That said I can see a use for server-side rendering even with Angular. For content that is fairly static it would be great to generate this server side, cache it, and then ngInclude it.

I'm starting a new side project in order to learn some new technologies and I have several doubts about the architecture I should use. My idea is developing an app both for web and for mobile (Android app mainly), so I think I need to implement the following: REST API service (with django-rest-framework). Web application (with django). Android app. After researching over stack overflow and Internet I have found 3 main "architectures" for the web part (server-rendering, client-rendering, and an hybrid model). In first place my idea was using the client-rendering model (with backbone or angular for the web client). However, I have seen that the hybrid model is a better choice. So here are my doubts: 1) Could I use django for server-rendering the web application pages? 2) Does Django web app "use" the API or the API is implemented using the same "library" as the django web? 3) Could/should I use a client framework (angular, backbone) for the web client (being server-rendered) ? Thanks in advance, and sorry about my short knowledge about django, etc.. This side project is just for that, to improve my knowledge about all this stuff.

We are thinking to move away from Django and separate the backend and frontend. The backend is straight forward as I have done it plenty of times by exposing it as a Python RESTful API. Whats new to me is the thin client part. Theoretically I could just write HTML and plain javascript to talk to the API. Is there a macro-framework that would help me to achieve that? Beside AngularJS, what other thin client frameworks could I utilise without reinventing the wheel?

Assuming you will be using a REST-based setup you might want to look into using ssl certificates and use https for verification and signal protection. For a simpler solution, use a pre-shared-key and put it in the header of the request. With that said your setup will only be as safe as your key management. Encryption and information security is hard. Good luck!

An alternative is to get the element[n] that you need in your view, and pass it to the template directly. Generally speaking, It's a better approch to pass to the template the data that you're going to actually use. So why pass a full list to use only one item of it?

If you need to store each row as a separate entity, it does not matter how you create these entities - you can improve the performance by batching your requests, but it won't affect the costs. The costs depend on how many indexed properties you have in each entity. Make sure that you only index the properties that you need to be indexed.

Using Methods Each handler class has methods with names like get and post, after the HTTP methods GET and POST etc. Those methods are functions that handle requests. Each request to your server will be routed to a request handler object, which is a new instance of some request handler class. So, a request handler instance is created per request, and is garbage collected once its HTTP response is sent. By inheriting from webapp2.RequestHandler, your handler classes get a bunch of functionality out the box for free. For example, handler instances will have the data from the HTTP request parsed into dictionaries and bound to self as self.request.headers and self.request.body automatically. The webapp2.RequestHandler class also provides self.response, which is what you write your response data to. Once the new request handler instance is initialised, the inherited __init__ method calls the method that maps to the HTTP request method, so assuming a GET request, it calls self.get. The webapp2.RequestHandler class doesn't implement those methods; your derived class does. Responding Neither print nor the return value of the handler method are used here. You do not 'return a response' with this framework; you write the response to the request handler instance's (inherited) self.response property. Your instance inherits self.response.out.write (which is aliased to self.response.write), which concatenates its argument to the body of the response, initially an empty string. Note: You can call self.response.clear to clear the response body. When you return from your handler method - get or post etc. - the return value is ignored. The framework uses the state of self.response to automatically create and send a HTTP response for you. There's a bunch of subtleties that the framework takes care of behind the scenes too. Classes Over Functions The main advantage is in inheritance. Normally, you'll create a single BaseHandler class that derives from webapp2.RequestHandler. The BaseHandler class will contain the core functionality for your actual handlers. It might include some logic for converting data into little JSON packages for a Web API, for example. All of the classes that actually handle requests would then be derived from your BaseHandler. You want a custom base class for your handler classes to derive from mainly so you can edit that base class. You want that base class to inherit from webapp2.RequestHandler so that all your handler instances inherit the framework magic. There is enough slight of hand to make the whole thing confusing, but it is easy to make sense of once you get it, and does save a lot of trouble. Technically, you could achieve all of the above just using functions and dictionaries, but Python is classically object oriented, so it would be painful and weird.

I'm a beginner and am wondering why we use self.response.out.write instead of print, and why we use classes, instead of functions, for the request handlers in the first place. Are there any special reasons?

Check whether element is clickable in selenium

You can use webElement.isEnabled() and webElement.isDisplayed() methods before performing any operation on the input field... I hope this will solve you problem... Else, you can also put a loop to check above 2 conditions and if those are true you can specify the input text and again you can find the same element and you can get the text of the webelement and compare that text with the text you entered. If those matches you can come out of the loop.

I'm able to verify whether or not an element exists and whether or not it is displayed, but can't seem to find a way to see whether it is 'clickable' (Not talking about disabled). Problem is that often when filling a webform, the element i want may be overlayed with a div while it loads. The div itself is rather hard to detect as it's id, name and even the css is flexible. Hence i'm trying to detect whether or not a input field can be 'clicked' or 'filled'. When the overlaying div is present, the field cannot be filled by a regular user (As the div would overlay the input field and not allow the user to fill it) but it can be filled by selenium. I want to prevent that and only allow selenium to fill it once the user can also fill it.

(Using PyCharm 4.0) Go to Tools --> Deployment --> and either select an existing server connection or create a new one. Under the Mappings tab, you can associate a local path with a remote path. I keep my Django project folder mapped to the one on the server. Once you hit OK, go back to Tools --> Deployment, and you should see a bunch of options available to you that were greyed out before, such as: Upload to [server name] Download from [server name] Sync to Deployed to [server name] Automatic Upload I find Automatic Upload handy for when I want the changes in newly saved Django files reflected on the server within seconds of hitting save.

I have an existing django project on an AWS instance. I have copied my Python files to my local machine. PyCharm is configured to use the Python interpreter on the remote machine. The django file references are, naturally, not resolved by PyCharm, since the django files are not on the local machine. Is the usual procedure to copy all the django files from the remote server to my local machine. Or is there another way to get PyCharm to know where to look to resolve the django references?

I'm writing a Django app that uses a management command to pull data from various sources. The plan is to run this command hourly with cron, and also have it run on user command from a view (i.e. when they add a new item that needs data, I don't want them to wait for the next hour to roll around to see results). The question is: How can I set up this command such that if it is already currently running, it won't execute? Is there some place where I can stash a variable that can be checked by the script before execution? My current best idea is to have the command monitor stdout for a while to make sure nothing else is executing, but that seems like a hack at best. This is the only task that will be running in the background. I'm basically trying to avoid using Celery here.

One approach might be: set up a database on a server on the internet program your app to save data to that remote database set up a webservice program the webservice to read data from the database and serve it as an html page For extra credit implement a REST style API which retrieves and serves data from the database create an ajax webpage which uses the API to fetch and display data (so you don't have to refresh the page constantly)

I'm trying to figure out how to have a real time data displayed on a webpage through the use of an android app. For example, users are using android app and are scored (answering questions). My webpage will display the scores in order in real-time. Iv come to the conclusion to use Redis, but what exactly do i need for this to function? Do i need a web socket where my web page will communicate with. This socket could be python where it accesses the database and then responds with the scores in order? Im struggling to find out how exactly this would work as this is new to me. What exactly should i be looking for (terminology etc)? Thanks

If it's an anchor tag, then just GET/POST whatever it is. The timer between links appearing is generally done in javascript - some sites you are attempting to scrape may not be usable without javascript, or requires a token generated in javascript with clientside math. Depending on the site, you can either extract the wait time in msec/sec and time.sleep() for that long, or you'll have to use something that can execute javascript

Rails app to work with a remote heroku database

I don't see any problem in doing this, as far as rails manages the database structure and python script populates it with data. My advice, but just to make it simpler, is to define the database schema through migrations in your rails app and build it like the python script doesn't exist. Once you have completed it, simply start the python script so it can start populating the Database (could be necessary to rename some table in the python script, but no more than this). If you want to test in your local machine you can one of this: run the python script in your local machine configure the database.ymlin your rails app to point to the remote DB (can be difficult if you don't have administration access to the host server, because of port farwarding etc) The only thing you should keep in mind is about concurrent accesses. Because you have 2 application that both read and write in your DB, would be better if the python script makes its job in a single and atomic transaction, to avoid your rails app finding the DB in an half-updated state. You can see the database like a shared box, it doesn't matter how many applications use it.

I have built an application in python that is hosted on heroku which basically uses a script written in Python to store some results into a database (it runs as a scheduled task on daily basis). I would have done this with ruby/rails to avoid this confusion, but the application partner did not support Ruby. I would like to know if it will be possible to build the front-end with Ruby on Rails and use the same database. My rails application will need to make use MVC and have its own tables on the database, but it will also use the database that python sends data to just to retrieve some data from there. Can I create the Rails app and reference the details of the database that my python application uses? How could I test this on my local machine? What would be the best approach to this?

There are a lot of different ways of generating pdfs from a django webpage in python2. The most clean, probably, is pisa and reportlab. These do not work for python3 though. So far, the only method I've had success with is to render the template, write it to a file, and then use wkhtmltopdf via subprocess.popen. This works alright, but it doesn't load any of my static files, such as css and images. Are there any proper solutions? can wkhtmltopdf read my staticfiles from the command line, in some way, or is there a library like pisa/reportlab, which supports python3? I haven't been able to finde such a library

After reading through and trying out various forum suggestions and spending solid time in Google, I've settled down with paramiko. It does exactly what I wanted and works like a charm for now. On click of a button on my website, running on server1, I make a request to run a python script. The python script uses paramiko to make SSH connections to server2, runs the necessary command and writes a response to a plain/text file. This plain/text file is rendered back to the request through django form as a response. This looks a little dirty now and there are more things to look into like, what happens if the command took very long time to execute or it erred out for some reason. I haven't spent time in figuring out answers for all those questions, but eventually will.

Have you checked your host's server logs to see if it's giving you any output? Before asking here, a good idea would be to ssh to your host, if you can, and running the program directly, which will most likely print the error in the terminal. This is far too general at the moment, there are so many reasons why a CGI request can fail ( misconfigured environment, libraries not installed, permissions errors ) Go back and read your servers logs and see if that shines any more light on the issue.

href="#" just refreshes the page when you select the link, for example if it was href=#top" when you select the link you would be brought to the top of that same page. You are probably doing it correctly, you can use driver.find_element_by_link_text('some text') or driver.find_element_by_partial_link_text('some text'), but clicking on that element is just routing you to that same page.

Coding in Python 2.7. I have a crawler I setup and it works perfectly fine when driven by FireFox, but breaks when driven by PhantomJS. I'm trying to click on an element with href="#" The crux of the issue is that when the FF driver clicks on this element with the # href, it performs the javascript action (in this case revealing a hidden part of a layer), but when PhantomJS does it, it either doesn't perform the click or it does click it but # just reloads the same page (I can't tell which one). I've tried everything I can think of, including multiple ActionChains and clicking element by element all the way down to this one with the link. Nothing seems to work. Any ideas?

You might have downloaded the wrong version of PyDev for your python version (2.7.5 or something is my python version, but I downloaded PyDev for version 3.x.x) 1) Uninstall your current version PyDev 2) you have to install the correct version by using the "Install New Software", then uncheck the "Show only newest software" or whatever it is. Then select the version that matched your python version, and install :)

I have a Django 1.6 project using Gunicorn+Nginx. I have cloned it to my web server (DigitalOcean) and it looked fine and the site was working. Then I made some changes on the projects in my PC and pushed to GitHub. Then I downloaded the updates by using git fetch -all and git reset --HARD. The project in the server side was successfully overwritten (I confirmed this by opening the file where there are changes). However, when I open my site in the browser, it only reflected some of the changes. Specifically: the HTML/CSS part is updated as the newest version; BUT, the urls.py and settings.py still followed the old setting. For example, I created a "/login" url in the newest version. But when opening the browser, it showed error. It seemed that it is still reading the setting.py and urls.py of the old branch. I tried git branch, it showed that I am currently working on the master one, which is the newest one; I also try restarting the Gunicorn and Nginx. Nothing different observed. Could anyone please enlighten me? Really appreciate any help.

Hi there so my question is probably about best practices when organizing ViewSets and the corresponding Routers in Django Rest Framework. According to the official documentation, the routers should be stored in the urls.py and the viewsets should be stored in views.py. My idea of an approach would be having the viewsets in a separate file like for example viewsets.py so that we don't end up mixing the normal Django views and the DRF Viewsets in the same file, improving readability. The same would go for the routers where we would creaate a file called routers inside each app and register then with the main Default router instance. These are my thoughts, but i am not sure how to: 1º Do this the proper way (the registering of the viewsets routers and all, should i place DefaultROuter in the __init__.py ?) 2º Is there a better approach? Basically i want to separate the logic per app and inside each app separate by django views and DRf viewsets

The Django Admin select menus use the unicode value of the model instance to populate things like menus. Whatever your __unicode__ method returns should be what is in the select menu.

At the moment there is no straightforward way to do this. But some workarounds can be found. For example, since Processing's python mode is using Jython language (Python on JVM) you can do the following: Compile the Jython code to Java bytecode Decompile Java bytecode to real Java code Use processing.js to make the sketch run in a webpage Of course, there are chances that the generated Java code will not be 100% Processing code, thus will not be converted to Javascript by the processing.js library.

The title says it all. I spent a lot of time designing a sketch in Processing using the Python language. Now, I would like to put the sketch on a webpage. Of course, I could just translate the sketch from python language to javascript and use a javascript library for processing. However, this would be a very lengthy process. As such, do you know if there is a way to integrate a python sketch in the website? If yes, how to do that? Thank you in advance!

I have a working Django 1.6 project using sqlite deployed in Digital Ocean, Ubuntu. I use Git to update my project on server side. (Git clone and git pull thereafter) My question is: every time after I update my database locally (e.g. added some new tables), how can I synchronise with the server one? Using git pull results in conflicts that cannot be resolved. I can do it using git fetch --all and git reset --HARD. But it doesn't seem to be the correct way. Any help is greatly appreciated! Thank you in advance.

SQLAlchemy ORM: safely passing objects between threads without manually reattaching?

Session.merge() is enough and should do what you're after, but even then it gets fiddly with threads. You might want to rethink this. Pass the primary key(s) to the worker instead of the objects, and then handle object loading and the actual work in the worker itself. No messing around with threading and open/closed sessions that will eventually lead to headaches. Once the workers can deal with the objects separately, you could even move the workers to a separate process (similar to what Celery does).

I'm working on a multithreaded application that uses the SQLAlchemy ORM. It already uses scoped_session with the thread as its scope, but we are having some issues when we pass an ORM object from a worker thread back to the main thread. Since the objects are attached to the worker thread's session, when the worker thread is shut down, we start getting DetachedInstanceErrors on those objects. Is there a way I can generically tell the ORM objects to detach/reattach themselves to the correct session as needed? We spawn a new thread whenever we have a slow operation that we don't want locking up our UI, so putting the reattach code in everywhere we spawn a new thread would be a mess. I think we also need to be able to clone the ORM object when we spawn the thread, so that we can have one in the main thread and one in the worker thread. I see a "merge" but no "split". Is this possible?

As soon as I made this regular Python file into another custom command file, it worked for what I needed.

I have a custom django admin call that I am able to successfully call from the command line using: python manage.py mycustomcommand. Therefore, the directories are setup with the necessary init files in 'management' and 'commands' folders, and I have listed the apps under INSTALLED_APPS in my settings file. When I try to run the command from another file and use call_command('mycustomcommand') is says the command is an unknown command. How does it work from the command line but not from call_command? I ran get_commands() from 'core.management' and my command is not listed there. Do I need to do something more so that it can be found? If it matters, I am trying to call mycustomcommand from an app directory that is different from the app directory where the custom command lives. All my app directories have the correct structure and are in INSTALLED_APPS. All my googling seems to suggest it should just work and I've tried all reasonable suggestions to no avail. Thanks for any insight.

You can try replicating what "works for me". Create a solution containing: python project (ironpython) C# project Add a reference to desired oracle library (Oracle.DataAccess.dll) to C# project using the standard VS mechanism. C# project should also contains a post build step to copy the resulting dll and pdb into the place where python script can find it. In my case root of the python project. Your python project is selected as Startup Project. I use Ctrl-F5 and F5 to start it. In both cases things work as expected. In debug mode I am able to set and hit breakpoint in python and in referenced C# module. I can see the oracle library being loaded (Output window of debugger). However: The stack traces are C# only. Visual Studio 2013 Update 4 together with PTVS 2.1 crashes on occasions when debugging.

I want to debug separate pieces of my application in Visual Studio 2012. I have C# executable which works with Oracle.DataAccess dll. It works fine. Within it IronPython runtime is invoked and it works fine too. Within these IronPython modules object from main C# application is invoked and it works fine with Oracle dll. If IronPython script is invoked standalone then it works fine and uses C# object fine as well. However in this case C# object doesn't see Oracle dll. To debug IronPython scripts I have to create separate Python solution so I cannot configure my C# solution. So I do not have control of C# references. GAC has right Oracle dll but how to tell C# dll to use it? Vise versa if I'm in C# solution where I can manage the references then I cannot add py files and debug them. In what way can I configure VS to be able to run/debug my application with dual entry C# or IronPython separately?

You can hardly hide the secret keys from an attacker that can access your server, since the server needs to know the keys. But you can make it hard for an attacker with low privileges. Obfuscating is generally not considered as a good practice. Your option 5 seems reasonable. Storing the keys in a non-source controlled file allows to keep the keys in a single and well-defined place. You can set appropriate permissions on that file so that an attacker would need high privileges to open it. Also make sure that high privileges are required to edit the rest of the project, otherwise, the attacker could modify a random file of the project to access the keys. I myself use your option 5 in my projects.

I have a Django app that uses some secret keys (for example for OAuth2 / JWT authentication). I wonder where is the right place to store these keys. Here are the methods I found so far: Hardcoding: not an option, I don't want my secrets on the source control. Hardcoding + obfuscating: same as #1 - attackers can just run my code to get the secret. Storing in environment variables: my app.yaml is also source-controlled. Storing in DB: Not sure about that. DB is not reliable enough in terms of availability and security. Storing in a non-source-controlled file: my favorite method so far. The problem is that I need some backup for the files, and manual backup doesn't sound right. Am I missing something? Is there a best practice for storing secret keys for Django apps or App Engine apps?

A solution I've seen is to store an encrypted copy of the secret configuration in your repository using gpg. Depending on the structure of your team you could encrypt it symmetrically and share the password to decrypt it or encrypt it with the public keys of core members / maintainers. That way your secrets are backed up the same way your code is without making them as visible.

http://www.example.com/soe/?param1=val1 this is current url and I want to access variable {{param1}} in django template. (Django 1.7) I know there are already many threads available for this problem but all of them are using ContextProcessor.(or render_to_response) I'm simply using return render(request, template, {}) and dont want to use ContextProcessors. One way to solve this problem is I pass the value of param1 when rendering, I mean return render(request, template, {'param1': request.GET.get('param1')}) but I'm just wondering If I can access this variable in template itself? because there might be 10 parameters.

Django best user model design

First, if you want to use email as username, use the Django custom user functionnality. It works well. Then, note that it's not because you created your own User that you can't extend it with a Profile. So, a good solution could be : Create a Django custom User without trying to add specific fields to it (the one and only purpose here is to use email to log instead of username). Create a PatientProfile class that have a one-to-one relatioship (blank=True) with User class. This way, a patient that can log in will be related to a User instance and will use this instance for this purpose. On the other hand, the patient who can't log in won't be related to any User instance. In the end, there's no problem to use OneToMany relationship with PatientProfile for what's you want to do.

Probably some of you would tell that is a recurrent topic, but after reading many articles, it still seems very ambiguous to me. My question is about the best way to use and to extend the User model preserving the authentication (and others) mechanisms available in Django. However, I prefer to describe my design: There are users (Patients) that can sign up providing basic info (first name, last name, birth date, gender, email, password). Preferably, email should replace the username. When a Patient is in the application, it can register a new Patient (imagine a member of the family), but email and password are not required because they won't log into the system. For the first part, Django doc propose to extend User with a OneToOne relation to a Profile. However, to replace username by email they propose then to create a custom User extending from an AbstractUser, as well as an associated UserManager. The second requirement is like doing a one-to-many relation from users to users. So, according to Django, which should be the best strategy: creating a completely new user model and the one-to-many user-user adding an specific attribute that distinguish between main users and family members? OR extending Django User with a Profile and then a one-to-many relation profile-profile? Which option preserves the best the benefits of Django user authentication and model administration? Thank you for any comment, suggestion, example.

The installer downloaded and built the Python and libxml2/libxslt components necessary to remedy the terribly out-of-date (and vulnerable) versions included with sles11sp3. System packages needed for the build were: gcc-c++ make readline-devel libjpeg-devel zlib-devel patch libopenssl-devel libexpat-devel man All installed via zypper. I'd advise not using sudo for the install. If you want to, you'll need to create the plone_daemon and plone_buildout users and the plone_group group in advance due to oddities in SUSE's adduser implementation.

I'm trying to install plone 4.3.4 on a SLES 11 SP3 64bit server via the Unified Installer.

I find that rather strange as in the description of the unified installer it is said "The new Zope/Plone install will use its own copy of Python, and the Python installed by the Unified Installer will not replace your system's copy of Python. You may optionally use your system (or some other) Python, and the Unified Installer will use it without modifying it or your site libraries." on the Plone-Website. So - what am I doing wrong??? I've just tried adding the parameter --build-python but had to find out that the libxml2-devel and libxslt-devel libraries that are available for SLES-11-SP-3 are sadly not up-to-date enough 2.7.6 instead of 2.7.8 and 1.1.24 instead of 1.1.26 respectively. So no joy there either. :-( Is there any way to install the current version of plone on SLES 11 SP3 64bit? Kate

Each project will have an assigned manager. Any number employees can enter time for a project. Once employees send their timesheet to be be approved, each respective manager will only get that portion of the timesheet for which time was charged to the project they managed. They should be able to view each project and the employees in them.

I haven't had any problems with slow performance on SQS, but then again it maybe that the be the nature of my apps don't count on sub-millisecond response times for items in my queue. For me the work done on the items in the queue contributes more to the lag than the time it takes to use the queue. For me the distributed, highly available and 'hands-off' nature of SQS suits the bill. Only you can decide whats is more important: a few more milliseconds of performance in a non-redundant system that you need to support yourself, or the 'queue as a service' offerings of AWS. Not knowing you application, I can't say if the perceived extra performance is a necessary trade off for you.

You do not have to do more than you have done, however, you should make sure that you do not have the server from your previous project running, for one. To confirm, are you at the point in the tutorial where you have run django-admin.py startproject mysite . You have also run python manage.py migrate. Also, make sure that you are running python manage.py runserver such that the manage.py you are running corresponds to the manage.py in your new tutorial project. That is, check which directory you are running from.

Why doesn't uWSGI listen on IPv6 interface, even if system is 100% IPv6 ready? As far as I could see there aren't parameters nor documentation covering this issue.

I started a new project a few months back using Django 1.7. The company has decided to settle on using Django 1.6 for all projects. Is there a nice way to downgrade from Django 1.7 to 1.6? Are migrations the only thing I have to worry about? Are the changes between the two versions large enough that I need to rewrite the app? I was hoping to just change the version in the requirements.txt and then install south and create new database migrations.

Ok, figured it out. What I needed to do was prefix my location with redis://. This is specific to the django-redis library and how it parses the location url. That explains why when I manually set up a StrictRedis connection using the python redis library I was able to connect.

I've got a django project using django-redis 3.8.0 to connect to an aws instance of redis. However, I receive ConnectionError: Error 111 connecting to None:6379. Connection refused. when trying to connect. If I ssh into my ec2 and use redis-py from the shell, I am able to read and write from the cache just fine, so I don't believe it's a security policy issue.

I have a Django project and I did the following: Added a table with some columns Insert some records into the db Added a new column that I didn't realize I needed Made an update to populate that column When I did a migrate everything worked just fine. The new db column was created on the table and the values were populated. When I try to run my tests, however, I now bomb out at step 2 above. When I do insert, I believe it is expecting that field to be there, even though it hasn't been created at that point yet. What should I do? EDIT: More info I first made a class, class A and did a migration to create the table. Then I ran this against my db. Then I wrote a manual migration to populate some data that I knew would be there. I ra n this against the db. I realized sometime later that I need an extra field on the model. I added that field and did a migration and ran it against the database. Everything worked fine and I confirmed the new column is in the database. Now, I went to run my tests. It tried to create the test db and bombed out, saying "1054 - Unknown column [my new column that I added to an existing table]" at the time when it is trying to run the populate data script that I wrote. It is likely looking at the table, noticing that the third field exists in the model, but not yet in the database, but I don't know how to do it better.

This happened to me because I faked one migration (m1), created another (m2), and then tried to migrate m2 before I had faked my initial migration (m1). So in my case I had to migrate --fake <app name> m1 and then migrate <app name> m2.

Unless the new column has a default value defined, the insert statement will expect to add data to that column. Can you move the data load to be after the second migration. (I would have commented, but do not yet have sufficient reputation.)

The answer is yes. Just simply setup your fb canvas url to this: https://yourdomain.com/your-allauth-url/facebook/login/?process=login With this, your canvas app visitor will go through the allauth facebook login process. If the user has connected to your app it will redirect him/her to the login redirect url you have specified in your settings. Otherwise it will just ask him to allow the facebook connection.

I'm building a small RESTful API with bottle in python and am currently experiencing an issue with character encodings when working with the request object. Hitting up http://server.com/api?q=äöü and looking at request.query['q'] on the server gets me "Ã¤Ã¶Ã¼", which is obviously not what I'm looking for. Same goes for a POST request containing the form-urlencoded key q with the value äöü. request.forms.get('q') contains "Ã¤Ã¶Ã¼". What's going on here? I don't really have the option of decoding these elements with a different encoding or do I? Is there a general option for bottle to store these in unicode? Thanks.

Running Out of Threads: UWSGI + Multithreaded Python Application with GeventHTTPClient

python,multithreading,uwsgi,gevent

Mixing non-blocking programming (geventhttpclient) with blocking one (a uWSGI thread/process) is completely wrong. This is a general rule: even if your app is 99% non blocking it is still blocking. This is amplified by the fact that gevent makes use of stack switching to simulate blocking programming paradigms. This is like cooperative multitasking, and it is managed by the so called 'gevent-hub'. Unfortunately, albeit your greenlets will be able to make http requests they will be never terminated because the gevent hub will never run again once the request is over. If you want to maintain the geventhttpclient approach you have to set uWSGI in gevent mode, but you need to be sure that all the modules and techniques used by your app are gevent friendly.

I'm currently running a python web API that is NOT multithreaded with much success on the uWSGI + NGINX stack. Due to new operational needs, I have implemented a new build that includes multithreaded requests to external data sources. However, when I deploy this new multithreaded build under uWSGI with --enable-threads, after a few minutes, the machine runs out of available threads. I was able to isolate the issue to my usage of geventhttpclient for my external HTTP requests by monitoring the thread count using ps -eLf | grep <process id>| wc -l. I have currently 2 worker threads (two external requests) in my application, so as I noticed, every time I hit/make a request from my API, the application thread use count increases by 2. If I swap my use of geventhttpclient with the standard python Requests module in just one of these worker threads, the thread count only increases by 1. NOTE: I am using HTTPClient.close() to close the connection within each thread. This leads me to suspect that geventhttpclient creates new threads that do not terminate when used in multithreaded uWSGI applications. Is there an easy way around this chokepoint? The performance of geventhttpclient is exceptional in non-multithreaded uWSGI applications, so I would love to continue using this. Thanks and let me know if I can provide any more information.

It's a python build step. print("""\ xxxx yyy ") It works many times, but not all the times - it messes up the next step when it fails. I'm not sure how to debug, but maybe I should just add a step that displays the contents of a text file on the console output log. I can't find such a plugin? thank you!

Run Python script in background on remote server with Django view

I'd humbly reccomend the standard library module multiprocessing for this. As long as the background process can run on the same server as the one processing the requests, you'll be fine. Although i consider this to be the simplest solution, this wouldn't scale well at all, since you'd be running extra processess on your server. If you expect these things to only happen once in a while, and not to last that long, it's a good quick solution. One thing to keep in mind though: In the newly started process ALWAYS close your database connection before doing anything - this is because the forked process shares the same connection to the SQL server and might enter into data races with your main django process.

I have a python script on my raspberry-pi continuously (every 5 seconds) running a loop to control the temperature of a pot with some electronics through GPIO. I monitor temperature on a web page by having the python script write the temperature to a text file witch I request from java script and HTTP on a web page. I would like to pass a parameter to the python script to make changes to the controlling, like change the target temperature. What would be the better way to do this? I'm working on a solution, where the python script is looking for parameters in a text file and then have a second python script write changes to this file. This second python script would be run by a http request from the web page. Is this a way to go? Or am I missing a more direct way to do this. This must be done many time before and described on the web, but I find nothing. Maybe I don't have the right terms to describe the problem. Any hints is appreciated. Best regards Kresten

Sound cards are for playing audio, not sending data. You can't rely on an arbitrary signal not being altered by the hardware, much less the software. For example, many sound cards have a capacitor in series with the output to filter out DC bias. If you try to pass a DC-biased (or very low frequency) signal through such a sound card, it will be distorted. And there's nothing you can do about it at the software level.

We have a python program which outputs specific waveforms over the audio to drive an LED, for an easy and cheap robot programming device. With the windows systems that we've tested everything works fine, but on some systems the waveform seems to be altered. We've used the control panel to disable any 'enhancements' for the audio output endpoint but it doesn't seem to help. So, is it possible, using python, to instruct Windows to play audio unchanged? Or do some of the audio gurus here have another theory of what could be affecting the audio?

Any change made directly in the OpenERP/Odoo GUI is not written back to the module and will overwritten in the next module upgrade. Use those direct changes only for experimenting or fast prototyping. Changes you mean to be final should always be made in your module files.

SO i'm using Open ERP 7 and wanted to make a custom module. I've put everything into PyCharm to edit parts there, but sometimes I edit some forms or add some fields with in OpenERP itself under the Database structure. Any changes I make under the Database Structure (e.g adding a field) won't show up in my PyCharm. Is there a way to keep them both in sync? Thanks in advance
