Problem with implementation of django-microsoft-auth in Django app with custom user model
I want to implement django-microsoft-auth library to my Django project and I am struggling with migrating data. The problem is that I am using Custom User model that does not contain a username field and when I am trying to run the foolowing command: python manage.py migrate I get error like this: SystemCheckError: System check identified some issues: ERRORS: <class 'microsoft_auth.admin.UserAdmin'>: (admin.E033) The value of 'ordering[0]' refers to 'username', which is not an attribute of 'user.User'. I've cloned the repository and I don't see anywhere in admin.py or in any other file that ordering is refering to a username field. My user model looks like this: class UserManager(BaseUserManager): """Define a model manager for User model with no username field.""" use_in_migrations = True def _create_user(self, email, password, **extra_fields): """Create and save a User with the given email and password.""" if not email: raise ValueError('The given email must be set') email = self.normalize_email(email) user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user def create_user(self, email, password=None, **extra_fields): """Create and save a regular User with the given email and password.""" extra_fields.setdefault('is_staff', False) extra_fields.setdefault('is_superuser', False) return self._create_user(email, password, **extra_fields) def create_superuser(self, email, password, **extra_fields): """Create and save a SuperUser with the given email and password.""" … -

How to optimize multi column indexing in Django with PostgreSQL

I have noticed an increased growth of the database allocated space and I was wondering if this is an overloading or unnecessary overlapping of indexes. -

How to find the location of a news article (i.e. the news is related to which place) from a news website?
I am making a news app that aggregates news from different news websites. I have successfully made the UI and the scrapping part is also done. But I am unable to get the location of the news article wherefrom the news is based. Suppose, the news is of Masachuttes from the USA Today. So, I need to extract the location - Masachuttes from the news website - USA Today. This is my problem description. So, I need your help in this regard. I tried the Geo-Location API but it did not work as it only asks for the user permission so it went in vain. As of now, I have no idea how to do it. Expectation is that I could scrape the loation of a particular news article of a news website. -
Override_settings not working at runtime with pytest DJANGO
In my settings.py file inside my django proyect I added a new constant ALLOW_SELF_REGISTRATION, that constant will allow or not a url in the proyect in the way: if settings.ALLOW_SELF_REGISTRATION: urlpatterns += [path( "self_registration/", views.self_registration_client, name="self_registration" ),] My problem is that I need to test when that constant is set to False in that case the url should not be added and a test to that url must raise a NoReverseMatch. I found that the override_settings is not working as expected, I do differents attemps to see if any could work, but no. Until now i tried: def test_constant_on_change_edit_urls_on_false(client): with override_settings(ALLOW_SELF_REGISTRATION=False): with pytest.raises(NoReverseMatch): response = client.get(reverse('profiles:self_registration')) If I print the value of the constant in that test is set to True (as default) and not False as it should by the override_settings context manager. I need a way to override that constant at runtime inside the tests so I can test that functionality. Also tried: @override_settings(ALLOW_SELF_REGISTRATION=False) def test_constant_on_change_edit_urls_on_false(client): with pytest.raises(NoReverseMatch): response = client.get(reverse('profiles:self_registration')) But also failed. There is any way to change that value at runtime during the tests? -
