Class ModelState

django.db.migrations.state.ModelState

Represent a Django Model. Don't use the actual Model class as it's not designed to have its options changed - instead, mutate this one and then render it into a Model as required.

Declaration

Documentation

Note that while you are allowed to mutate .fields, you are not allowed
to mutate the Field instances inside there themselves - you must instead
assign new ones, as these are not detached during a clone.
