Django: Unit Test Fixtures not loading in VSCode Debug Mode
I have written some unit tests with Django, with fixtures set up. I want to debug these tests and have a configuration on VSCode to do this... { // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "Django: Test Unit Case", "type": "debugpy", "request": "launch", "args": [ "test", "apps.students", "-v 2" ], "django": true, "autoStartBrowser": false, "program": "${workspaceFolder}\\server\\manage.py" }, ... ] } I have my FIXTURE_DIR configured correctly, as when I run the command py manage.py test apps.students, the fixtures load and give no error.

Why does django override css variable name from db?
I'm taking over a django+react project from a guy who left the company, but this is the first time I work with django so I'm somewhat clueless. The project is a status management page with calendar and stuff (sqlite3 as db). Possible statuses (like In Office, or Sick Leave) and their corresponding data is stored in db, including color for the status. The color was previously stored as a css hex string without the # (got prepended later by code). But the color values are used at multiple places, so they were copy-pasted many times. Since the colors might change, I wanted to get them all together, so I created css variables like '--in-office-color: rgb(whatever)', and changed db to contain the strings 'var(--in-office-color)' and so instead. Now when I want to return it in a view like this: class SomeView(APIView): def get(self, request): //... data = { /* other profile data here */ "statuses": {i.id: {"name":i.name, "color": i.color} for i in Statuses.objects.all()} } return Response(data) Then in the response some css variables are ok, and some got changed. The two problematic ones are "--in-office-color" which changes to "--in.office-color" and "--home-office-color" also changed to "--home.office-color" (whilst "--out-of-office-color" remains unchanged for example) … -

What is pytests equivalent to setUpTestData in Django?
I have seen TestCase.setUpTestData which improves test speed quite a bit in my case. I typically prefer pytest fixtures instead of the TestCase classes. However,when I make a session-scope fixture which does data preparation needed for all tests with the fixture, I get RuntimeError: Database access not allowed, use the "django_db" mark, or the "db" or "transactional_db" fixtures to enable it. I followed https://stackoverflow.com/a/72261942/29412366, but that had no effect. How can I store and re-use a DB state within a Django application when testing using pytest? I use an in-memory sqlite3 DB. I tried https://stackoverflow.com/a/72261942/29412366 : @pytest.mark.django_db @pytest.fixture(scope='session') def thing(django_db_setup, django_db_blocker): del django_db_setup # Cannot be used with usefixtures(..) it won't work with django_db_blocker.unblock(): print('sleeping') Thing.objects.create(thing='hello') and expected the test to run successfully + save time. Instead, I got the RuntimeError mentioned above. (function-scoped fixtures work fine, but then I don't save any test execution time) -

Images not displaying after deploying Django app to Render, but they work locally
I’ve deployed my Django application on Render, and while everything works perfectly locally (including images), the images are not displaying after deployment. The other static files, like CSS and JavaScript, are loading fine, so I believe the issue might be specific to serving media files. Here’s what I’ve checked so far: MEDIA_URL and MEDIA_ROOT: I’ve configured the MEDIA_URL and MEDIA_ROOT in my settings.py as follows: python Copy Edit MEDIA_URL = '/media/' MEDIA_ROOT = '/mnt/data/media' # Path to Render persistent disk Persistent Disk: I’m using Render's persistent disk and confirmed that the images are correctly uploaded to the server. File Permissions: I’ve checked the file permissions, and they seem to be correct. However, despite all this, the images are not showing up on the live site. Can anyone help me figure out why the images aren’t displaying on Render? Do I need to adjust the configuration for serving media files, or is there something I missed in the deployment process? Thanks in advance! I’ve deployed my Django application on Render, and while everything works perfectly locally (including images), the images are not displaying after deployment.

Is there any way to handle this error I'm facing with my Django project?

Django imported database -- am I doing it wrong? Is Django not fit to purpose here?
So perhaps I'm missing something conceptually, or simply doing it wrong. Or, worst case scenario, "that's not what Django is for" :-/ I have set up my Django instance to fully take advantage of an external database which contains, amongst other things, all of my iTunes (no, not Music) data, with an extensive changelog. That's tangential to my question but I wanted to throw it out to show that I'm not a complete beginner (I even have it set so Django doesn't mess w/the external read-only database, which is a bit of a feat). What I'm trying to do is import this into Django models in my actual Django database, to take advantage of the Django admin, preparatory to creating a web app around all of this. I've set up the Django models, and created some (SQLAlchemy) routines to ETL my data into three tables (Songs, Artists, Albums). I have a lot of data (783122 songs from 59445 albums by 97562 artists), but that shouldn't overload a robust framework like Django, I wouldn't think. So the data's imported & I've set up a basic admin which should simply show the songs inline when I go to the admin page for … -

Saving data to the database in django
I am working on a website to recommend stocks on the stock market, based on historically reliable trading strategies. When running the server, I can't see any of the data which is supposed to be shown on the website. Looking into the db, it appears that most of the data is not being saved to the db. There is also another problem, which may be related: When running the code, I am getting the company name for the last stock which is being looped through, but for the others there it just says 'None'. I would be grateful if anyone can help me with this. Here is the code to loop through each stock: def compile_queue(self): from stock.models import Stock list_of_stocks = Stock.objects.prefetch_related("stock_data", "strategies", "recommendations").values('ticker')[0:101] for i in list_of_stocks.values(): try: #Update db with new data ticker = i.ticker stock_object = Stock_Class(ticker) self.list_of_operations.append(lambda i=i: stock_object.update_data(i)) # Get strategy objects moving_average_strategy = Moving_Average_Strategy(ticker) rsi_strategy = RSI_Strategy(ticker) bollinger_band_strategy = Bollinger_Bands_Strategy(ticker) # Add strategies to the queue self.list_of_operations.append(lambda:moving_average_strategy.apply_strategy()) self.list_of_operations.append(lambda:rsi_strategy.apply_strategy()) self.list_of_operations.append(lambda:bollinger_band_strategy.apply_strategy()) self.list_of_operations.append(lambda:stock_object.set_recommendations(i)) except Exception as e: print(f"(Trading_System.py) The required actions for {i} could not be run due to Error: {e}") Here is part of the code which gets the data for a given stock and … -

only works on first try with listening to keystrokes on input form field using jquery listener
Here is the basic situation: I want to be able to listen to user input on a text input box, the code will use ajax to check the entry after a pause of 5 seconds, against the cached answer. The check works just fine on the first try (after 5 seconds). But if the user blurs out to another field, then tries a second time to enter the correct answer, editing the same field, nothing happens, the ajax request is not performed. The listener seems to have disappeared or stopped working. Here's the code on the template side: let ajax_call = function (endpoint, request_parameters) { $.getJSON(endpoint, request_parameters) .done(response => { ...... }) //response handling }; answerInputs.on('keydown', function(){ answer = $(this); setTimeout(function(){ var answer_seq = answer.data("sequence"); answers[answer_seq] = answer.val(); var request_parameters = {'answers': JSON.stringify(answers), 'idList': JSON.stringify(idList)} // if scheduled_function is NOT undefined, cancel the execution of the function if (typeof(scheduled_function)!='undefined') { clearTimeout(scheduled_function); } // setTimeout returns the ID of the function to be executed scheduled_function = setTimeout(ajax_call, delay_by_in_ms, endpoint, request_parameters); }, 5000); }); -

In this example: @action( detail=True, methods=['POST'], name='Duplicate one resource', url_name='duplicate', url_path='duplicate', ) @transaction.atomic def duplicate(self, request, pk=None): foo = self.get_object() # gets foo foo_bars = foo.foo_bars.all() # gets a queryset of FooBar new_name = self.append_copy_suffix(foo.name) new_foo = foo.copy_instance(name=new_name) # code below print(foo, new_foo) FooBar.objects.bulk_create( [FooBar(foo=new_foo, bar=foo_bar.bar, stuff=foo_bar.stuff) for foo_bar in foo_bars] ) return Response(self.get_serializer(new_foo).data, status=status.HTTP_201_CREATED) def copy_instance(self, **kwargs): """ Method to copy a model instance More info here: https://docs.djangoproject.com/en/3.1/topics/db/queries/#copying-model-instances :param kwargs: additional parameters to update :return: the duplicated resource """ new_resource = self new_resource.pk = None for k, v in kwargs.items(): setattr(new_resource, k, v) new_resource._state.adding = True new_resource.save() return new_resource This works pretty well in Django 3.1, but in Django 3.2, the related resources are not created for some reason. Things that I noticed in debug and printing the values: When I print the foo and new_foo, they are the same one (new_foo). foo_bars is empty. Maybe because the foo and new_foo are the same one before the bulk_create and the foo_bars is just a queryset that was yet to be …
