Hi Adam, Migrations build a fake app registry containing fake app configs for each state of the models.
They implement a small subset of features of the real app configs. See https://github.com/django/django/blob/5e32605/django/db/migrations/state.py#L119-L131 That’s why my_app_config.models_module is None in your example. -- Aymeric. > On 31 déc. 2014, at 06:01, Adam Venturella <[email protected]> wrote: > > Attempting this approach, calling : > > create_permissions(my_app_config) > > from within my migration fails to create the permissions.
