Re: A lot of Problems with Migrating (conceptual)

# later in forms.py

category = forms.TypedChoiceField(required=False, choices=get_categories)

This has a similar effect to the ModelChoiceField, with the query only running when the form is instantiated, but gives you the flexibility to use whatever logic you'd like to come up with the choices for the field.

Forgot the doc link:

https://docs.djangoproject.com/en/1.11/ref/forms/fields/#django.forms.ChoiceField.choices
