Unable to migrate: "TypeError: reload_model() got an unexpected keyword argument 'delay'"

[gregbrowndev]

Hi, I am unable to migrate due to reload_model called with incorrect arguments, specifically delay is passed in but this is not in the function parameter list.

In AlterConstraints:

def state_forwards(self, app_label, state):
        model_state = state.models[app_label, self.name_lower]
        model_state.options[self.option_name] = self.db_constraints
        state.reload_model(app_label, self.name_lower, delay=True)

Getting error: "TypeError: reload_model() got an unexpected keyword argument 'delay'".

Currently on:

• Django (1.10.8)
• django-db-constraints (0.3.0)

If its just a versioning issue can you tell me which version of Django to use? Thanks

Updating to Django (1.11.6) resolved the issue
