Am a new Django User and am finding difficulties making a query to my database

[Abdul-Waris Dawuda]

Hello Everyone

 

Am new to Django and am currently facing a problem trying to import a class from my models.

i get this error when i try to do that from the Shell. I am using Visual Studio. i get this problem when i run my command to import;

>>> from app.models import Artist

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File ".\app\models.py", line 8, in <module>

    class Artist(models.Model):

  File "C:\Users\Abdul-Waris\source\repos\DjangoWebProject2\DjangoWebProject2\env\lib\site-packages\django\db\models\base.py", line 110, in __new__

    app_config = apps.get_containing_app_config(module)

  File "C:\Users\Abdul-Waris\source\repos\DjangoWebProject2\DjangoWebProject2\env\lib\site-packages\django\apps\registry.py", line 247, in get_containing_app_config

    self.check_apps_ready()

  File "C:\Users\Abdul-Waris\source\repos\DjangoWebProject2\DjangoWebProject2\env\lib\site-packages\django\apps\registry.py", line 125, in check_apps_ready

    raise AppRegistryNotReady("Apps aren't loaded yet.")

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

Did you include your app in the installed apps list in your settings.py file?

Did you do the makemigration and migration after creating the model?

Check these two steps and then try again. That's what I'm suspecting given the error trace.

Well, the simplest answer is you used the python shell and not the
django shell via `python manage.py shell`.
The app not being in installed apps gives a slightly different error
and migrations have little to do with it as importing a model doesn't
hit the database.

So simply use `python manage.py shell`. Or do this:

% env DJANGO_SETTINGS_MODULE='myapp.settings' python
Python 3.6.2+ (heads/3.6:95b16a9, Jul 27 2017, 14:00:36)
