OAUTH2_PROVIDER_ACCESS_TOKEN_MODEL Circular Dependency

[renderbox]

When trying to run migrations where we define OAUTH2_PROVIDER_ACCESS_TOKEN_MODEL as a custom model, it fails consistently.

./manage.py migrate

results in:

`ValueError: Related model 'shared.OrbitalAccessToken' cannot be resolved

Commenting out OAUTH2_PROVIDER_ACCESS_TOKEN_MODEL let's me apply all the migrations but this solution creates an unworkable solution for automatic deployments.

If after all the tables that are expected are generated and I want to run > ./manage.py migrate to make sure (I expect it to say all migrations are applied already), I get this error:

ValueError: The field oauth2_provider.RefreshToken.access_token was declared with a lazy reference to 'shared.accesstoken', but app 'shared' doesn't provide model 'accesstoken'.

I even tried wiping out my DB table & all my migrations just to see what would happen and in that case I get this error:

django.db.migrations.exceptions.CircularDependencyError: oauth2_provider.0001_initial, shared.0001_initial

Also tried setting the 'run_before' value:

run_before = [
    ('oauth2_provider', '0001_initial'),
]

but because of the dependency on migrations.swappable_dependency(settings.OAUTH2_PROVIDER_APPLICATION_MODEL) it fails.

This is with Django 1.10.7, Python 3.6.0 & Postgres 9.6

+1 for getting this solved, it's been a major headache for me

I think this is the same as #227.

[dv321]

Seems to be, there still doesn't seem to be a fix though since the run_before attribute just causes circular dependencies

[dv321]

Additionally once I've inherited from and swapped out the AbstractAccessToken any migration that attempts to delete the model fails. So now I'm locked in to just having to keep this table around in my db forever?

[jleclanche]

Sorry; I simply don't know. If someone has a solution proposal I can help look into it and merge it.

I was able to work around this by also using a custom application model. Then using run before in my migration. My custom application model doesn't do anything but makes the migrations work.

class Application(AbstractApplication):
    class Meta:
        db_table = 'oauth2_provider_application'
