Django 3.2 makemigrations ProgrammingError: table doesn't exist for abstract model

136 Views Asked by At

I'm currently updating my website to use Django 3.2, but I use the zinnia blog which is no longer receiving updates. I'm making the necessary changes to bring it up to compatibility with 3.2 but I'm now getting the error that the AbstractEntry table doesn't exist. This is, however, an abstract table so I'm confused why it would try to find the table at all.

Full traceback:

In Meta class you have to specify managed=False to prevent orm creation
