This doc <https://docs.djangoproject.com/en/1.11/topics/db/models/#multiple-inheritance> says multiple inheritance with a common ancestor can do the job. However, I've experienced an error while making migrations. Here's the error message.
> models.E005: The field '*<common-ancestor>*_ptr' from parent model ' > *<myapp>.<parent-1>*' clashes with the field '*<common-ancestor>_*ptr' > from parent model '*<myapp>.<parent-2>*'. After some googling, I fount this stackoverflow Q&A <https://stackoverflow.com/questions/31118645/django-multiple-inheritance-e005> . This solves the problem by create an explicit different parent_link in parent model to prevent collision. But it seems redundant to hold two multiple ancestor link in the child model. Is there any solution with no redundant field? -- You received this message because you are subscribed to the Google Groups "Django users" group.
