If the data is not important, try to delete migration files from `migrations` package, drop the database tables and reference M2M relationship using strings like so:
tags = models.ManyToManyField(`Tag`) Or if the Tag model is in another app, like so: tags = models.ManyToManyField(`app_name.Tag`) Can you also share the `Tag` model and related `ModelAdmin` classes?
