extending abstract model in Django












0














I'm using Django 2.x and OAuth Toolkit.



I'm writing an application where I need to add ForeignKey pointing to Application model of OAuth Toolkit plugin, which is defined Abstract.



According to the documentation. I can extend the AbstractApplication and then add in settings



OAUTH2_PROVIDER_APPLICATION_MODEL='your_app_name.MyApplication'


In my case, I have created my app and in models.py



class CustomOAuthToolkitApplication(AbstractApplication):
pass


class OAuthToolkitTrackingLog(models.Model):

application_model = settings.OAUTH2_PROVIDER_APPLICATION_MODEL

application = models.ForeignKey(application_model, on_delete=models.CASCADE, blank=True, default=None, null=True)
user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True, default=None)
col_1 = models.CharField(max_length=255)

created = models.DateTimeField(auto_now_add=True)


and in settings.py



INSTALLED_APPS = [
...
'oauth2_provider',
'my_app',
]

OAUTH2_PROVIDER_APPLICATION_MODEL = 'my_app.CustomOAuthToolkitApplication'


But when I run command to generate migration



python manage.py makemigrations


It gives error as



The field oauth2_provider.Grant.application was declared with a lazy reference to 'my_app.customoauthtoolkitapplication', but app 'my_app' isn't installed.
The field oauth2_provider.RefreshToken.application was declared with a lazy reference to 'my_app.customoauthtoolkitapplication', but app 'my_app' isn't installed.


How can I fix this issue?

          INSTALLED_APPS = [

          'oauth2_provider',

          So that my_app is higher on the list?
