Column doesn't exist when adding new field or removing a field after makemigrations or migrate command

[Gonzalo Vera]

This issues raises when you want to add or delete a field from a model and that model is used in a form before. We have here the egg-chicken problem. makemigrations parse the form (i do not why) and he detect changes on those fields and raise the error. (Bold fonts):
I fixed that issue commenting or replacing all the lines with bases.objects.all() (the compromised model) by anything or an empty string on the form. After that i ran makemigrations again, migrate, re-composed fake lines on the forms and that was right.
I think this issue could be on migrations documentation or be fixed. Also didnt found solutions on Django 3.
Thanks very much.

I'm sorry but from the current description I don't understand what kind of issue you're trying to report. makemigrations has nothing to do with forms and you cannot work with nonexistent fields. It looks like a support question, so please use as a support channel. Closing per TicketClosingReasons/UseSupportChannels.
