Optimize Django tests with preloaded database
I am trying to reduce my CI usage and make my code cleaner by pre-loading my test database using a custom class. I had multiple files/classes that looked like this: class TestSomething(TestCase): def setUp(self): User.objects.create(...) def test_something(self): pass I converted them into: class TestSomething(PreloadedTestCase): def test_something(self): pass with a common PreloadedTestCase class: class TestSomething(TestCase): def setUp(self): User.objects.create(...) This does make the code cleaner and removes a lot of duplicate lines, but it seems to increase the CI execution time. Is PreloadedTestCase.setUp() run multiple times? If so, how can I have a common class that is run only once against the database? I looked into fixtures but it is only populating the database, I would have to query it to access my objects in the tests. -
What's the default value for a DecimalField in Django?
I'm adding a new DecimalField to my model, what value will it have by default in the database (if I don't specify the default explicitly)? amount = models.DecimalField(max_digits=15, decimal_places=3) I'm expecting it will be either NULL or 0.0 (or None or Decimal(0.000) in python), but which? Couldn't find this mentioned in the docs: https://docs.djangoproject.com/en/2.2/ref/models/fields/#decimalfield I'm using Django 2.2, but expect this is consistent across versions. -

Django 4 and Unittest loader
We use Django for an online webshop, and want to upgrade to Django 4. However, since upgrading on a test branch, we have a problem, that I will highlight here. We serve two different markets, lets call them Market A and B :) Since these two markets can have different functionalities, our INSTALLED_APPS gets populated like so: MARKET_SPECIFIC_APPS = { MARKET_A: [ 'market_a.apps.MarketAConfig', 'payment_system_a.apps.PaymentSystemAConfig' ], MARKET_B: [ 'market_b.apps.MarketBConfig', 'payment_system_b.apps.PaymentSystemBConfig', ], } if MARKET in MARKET_SPECIFIC_APPS: # If there is a market-specific app, add it to INSTALLED_APPS INSTALLED_APPS += MARKET_SPECIFIC_APPS[MARKET] However, when running MARKET specific tests for each market, only MARKET_A passes. MARKET_B now throws an error, since upgrading from Django 3.2 to Django 4 RuntimeError: Model class payment_system_b.models.payment.Payment doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. Meaning, this test is still run, and the test runner includes it in INSTALLED_APPS even tho it shouldnt. Is there any change from the Django 4 changelog im missing about this? Running these market-specific tests was working fine before upgrading to Django 4 -

Django template won't respond to css file , worked briefly yesterday
It is exactly how it sounds. My main goal is to make the css file work with django template so I can design my templates. Yesterday I tried and initially my folder structure was wrong. I placed static folder in myapp folder. Didn't work. I tried putting it in templates folder. It only worked when I had 2 static folders both in myapp and templates folder. Realized it isn't a working solution. I placed a single static folder with a css file in it in mysite folder, at the same level with myapp folder and everything seemed to work. Satisfied I left at that. Today I came back to it and it stopped working. It seems to be frozen. Not responding to the new codes. Old colors are showing but new colors aren't, which is odd. Tried changing the old colors, it won't change. Literally my css file has a class name .intro where I changed the color from purple to red, my template still showing purple which I set yesterday. My template shows no error and all the texts and divs I am adding are updating with no issue.Kind of lost where I may have gone wrong. Certainly don't … -
How to open a modal when moving a page
The currently implemented code shows the modal when clicking the button. However, I would like the modal to be displayed when moving to the main page after logging in.
