Hi Micheal, thank you for providing more information here. Django does
generate migrations that cannot be applied.
The generated migration file usually reflects what you have asked Django
to do and it can only apply successfully if it is "valid".
Here `User` is dependant on `PermissionsMixin` (it is possible that
`PermissionsMixin` has some fields defined on it for example) and
`PermissionsMixin` is dependant on your locals as this is an output of a
function ran at startup. IMO you can simplify your code to have a valid
migration generated.

If you need any support with your project, please use one of our support
channels such as the [https://forum.djangoproject.com/c/users/6 Django
forum]. It is recommended to go there first and confirm with others if
there is agreement that this is either a bug in Django or something new
Django should support.

Comment (by Michael):

 I created a minimal reproducible example:
 https://github.com/mangelozzi/djangomigrationbug

 1. Check accounts/migrations/0001_initial.py
 2. You will see this line
 bases=(plug.permpp.PermissionsMixin_factory..PermissionsMixin,
 models.Model, accounts.modelpp.NiceNameMixin),
   - It has an error ``
 3. Delete the above migration file
 4. Run python manage.py makemigrations
 5. The file above with the error will be created by the Django.

Comment (by Michael):

 Hi, there is not an error or bug in my code. Django generates code that
 cannot run. My code runs fine. Everytime I generate migrations, I have to
 manually edit them so they are runnable. This is a bug in Django.

* resolution: => invalid

Comment:

Hello!

First of all, please note that you are using a version of Django that is
no longer supported (4.0.1).
Secondly, the error seems to be caused by either:

1. a possible misconfiguration/bug in your code, or
2. the result from squashing the migrations is somehow invalid.

For the first case, the recommended approach is to first ensure whether
the error you are getting is a bug in Django itself, or not in your code.
To do that, you can follow
[https://docs.djangoproject.com/en/4.2/internals/contributing/bugs-and-
features/#reporting-bugs the bug reporting guide] and seek help in the
Django User channels to evaluate whether your problem is caused by a
configuration issue.

For the second case, we would need a minimal example of two working
migrations and their minimal models that, when squashed, would generate
the invalid result. It's important to try to narrow the models and
migrations to the bare minimum that triggers the issue, and that what's
shared in the bug is fully functional. At the very least we'd need the
migrations that were squashed down to the result you pasted in this
report.

Closing this ticket as invalid for now, but if you find a concrete bug in
Django itself or if you can provide a reproducer for the faulty squashed
migration, please let us know and we'll analyze this further. Thanks!

 Changing this line from:
 {{{
 bases=(core.djpp.permpp.PermissionsMixin_factory..PermissionsMixin,
 models.Model, djpp.modelpp.NiceNameMixin),
 }}}
 to:
 {{{
 bases=(models.Model, djpp.modelpp.NiceNameMixin),
 }}}
 Make it work fine, since `PermissionsMixin` does not define any DB fields,
 is just run time behavior, but I thought this issue might highlight an
 underlying problem.
