Salesforce router causing issues with migrations

Hi,

Let’s start by thanking everyone working on this project : great work!

This is my first issue with the library : i’m doing some completely unrelated work in an other database (MySQL), including renaming some models. When I apply the migrations, I have a crash. It comes from the Salesforce router

  File "python3.5/site-packages/django/db/utils.py", line 291, in allow_migrate
    allow = method(db, app_label, **hints)
  File "python3.5/site-packages/salesforce/router.py", line 65, in allow_migrate
    model = apps.get_model(app_label, model_name)
  File "python3.5/site-packages/django/apps/registry.py", line 207, in get_model
    return app_config.get_model(model_name, require_ready=require_ready)
  File "python3.5/site-packages/django/apps/config.py", line 170, in get_model
    "App '%s' doesn't have a '%s' model." % (self.label, model_name))
LookupError: App 'XXX' doesn't have a 'YYYY' model.

Not sure what’s the purpose of “allow_migrate” precisely. But what’s surprising is that even by calling ./manage.py migrate --database default, the issue remains (“default” being my SQL database)

The only solution I’ve come up with is to remove the salesforce router from settings.py dynamically when applying migrations…

Any idea what could cause such issue?

Thanks

I prepared a fix hynekcer/ignore-migrations (temporarily on March 16) (EDIT: moved to PR #233 and merged f835680a), but still I need to write a test. It is not easy to write a simple test for migrations. This remains open.
