Similar field names with PageUser and my custom user model

I have a similar problem as @jrief describes in #3973. We use django 1.8.2 with a custom user Model and as i tried to install django-cms 3.1.1 i got the following error:

django.core.exceptions.FieldError: Local field 'created_by' in class 'PageUser' clashes with field of similar name from base class 'Contact'

Unfortunately my custom User model already has a created_by Field. And django does not allow to override any Field attribute from the parent Model.

Since the PageUser model does not add any logic rather than the created_by Field, the best solution for me would be to swap the PageUser model like django does with auth.User. Are there any Plans to support that functionality? If not, i could invest some time and send a PR.

Or anyone else ran into the same problem and can give a hint?

This issue still exists with 3.2.5 as the PageUser model has not changed.

@yakky correctly states that a OneToOneField would be a better way to store CMS user data than inheriting from AUTH_USER_MODEL.

Another, more short-term, strategy would be to rename the field to something that is less probable to clash with a custom user model, such as page_user_created_by:

class PageUser(User):
    page_user_created_by = models.ForeignKey(settings.AUTH_USER_MODEL, 
                                             related_name="created_users", db_column='created_by')

@walterrenner PageUser is a way to add information to the User, and it’s not mean to be a User model substitute Long-term, they way to fix this is to use an explicit OneToOneField, rather than extending from the User model
