migration does not consistently rename field "id" to "model_id" depending on model name

[Shadi Akiki]

In the case where the model is

 class Something(models.Model):
    field1 = ...
    field2 = ...

adding a field

    something_id = models.AutoField(verbose_name='ID', serialize=False, auto_created=True, primary_key=True)^M

generates a "rename" in the migration from "id" to "something_id".

However, for

 class MyModel(models.Model):
    field1 = ...
    field2 = ...

adding a field

    mymodel_id = models.AutoField(verbose_name='ID', serialize=False, auto_created=True, primary_key=True)^M

does not generate a "rename" in the migration.

Can you confirm the issue still happens if you remove serialize and primary_key? These flags shouldn't be when declaring a PK explicitly.

I'm not able to reproduce:

$ python manage.py makemigrations
Did you rename mymodel.id to mymodel.mymodel_id (a AutoField)? [y/N]

The model:

class MyModel(models.Model):
    mymodel_id = models.AutoField(verbose_name='ID', serialize=False, auto_created=True, primary_key=True)
