Why does this hacky way of specifying installed_apps in Django work, but not the proper way?
My file structure is like this: and the INSTALLED_APPS in settings.py looks like this: INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "nstv_fe", "django_tables2", ] With this setup, running a script that imports a model from nstv_fe (from nstv_fe.nstv_fe.models import Show), I get the following error: # If "not ready" is due to unconfigured settings, accessing # INSTALLED_APPS raises a more helpful ImproperlyConfigured # exception. settings.INSTALLED_APPS > raise AppRegistryNotReady("Apps aren't loaded yet.") E django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. ../../venv/lib/python3.8/site-packages/django/apps/registry.py:135: AppRegistryNotReady Most of the stackoverflow questions about this are answered by setting the DJANGO_SETTINGS_MODULE environment variable to the settings file - so I tried setting it to nstv_fe.nstv_fe.settings and nstv_fe.settings, but neither worked. What I find odd is that if I go into django/apps/registry.py and manually create a list: installed_apps = ['nstv_fe'] in the Apps class, it'll run the test for the script that imports the model no problem. But if I don't manually add that line, it'll give me the AppRegistryNotReady error. This leads me to believe that nstv_fe isn't getting picked up properly in the installed apps somehow, but I'm not sure where I'm going wrong because I have it in the INSTALLED_APPS list in settings.py.

How to give an object multiple ratings (on different aspects) with django-star-ratings app?

Usar múltiplas database no DJANGO
Bem, comecei estudar django esse ano e veio uma dúvida e não consegui arrumar. O problema é que tenho várias database no mysql e algumas possuem relações entre elas.

Ai tenho outra database que faz relação com essa DatabaseName1, mas já deu ruim :( kk Já tentei: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'DatabaseName1', 'USER': 'DatabaseUserName', 'PASSWORD': 'DatabaseUserpassword', 'HOST': 'localhost', 'PORT': '5432', }, 'segunda': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'DatabaseName2', 'USER': 'DatabaseUserName', 'PASSWORD': 'DatabaseUserpassword', 'HOST': 'localhost', 'PORT': '5432', } } O user, password, host e port são os mesmo, isso é possível? -
Wagtail upgrade from 2.12 to 2.13 -- migrations not applying
I have a Wagtail project using the following: Wagtail 2.12.4 Django 3.1.11 Python 3.8.5 Postgres 12.6 I tried to upgrade Wagtail to version 2.13. When I run python manage.py migrate after the upgrade, the migrations appear to complete successfully, and they show as having completed when I run python manage.py showmigrations. However, the database tables targeted by the migrations remain unchanged, and the migrations do not appear in the django_migrations table of the database. This problem persists even if I run the specific migration with python manage.py migrate wagtailusers 0010. I have looked online for similar issues, but I haven't been able to find anything. Any advice on how I can find what is causing this issue to happen? -
