python - Why does Django make migrations for help_text and verbose_name changes?

Question

When I change help_text or verbose_name for any of my model fields and run python manage.py makemigrations, it detects these changes and creates a new migration, say, 0002_xxxx.py.

I am using PostgreSQL and I think these changes are irrelevant to my database (I wonder if a DBMS for which these changes are relevant exists at all).

Why does Django generate migrations for such changes? Is there an option to ignore them?

Can I apply the changes from 0002_xxxx.py to the previous migration (0001_initial.py) manually and safely delete 0002_xxxx.py?

Is there a way to update previous migration automatically?

Answer 1

You can squash it with the previous migration, sure.

Or if you don't want to output those migrations at all, you can override the makemigrations and migrate command by putting this in management/commands/makemigrations.py in your app:

from django.core.management.commands.makemigrations import Command
from django.db import models

IGNORED_ATTRS = ['verbose_name', 'help_text', 'choices']

original_deconstruct = models.Field.deconstruct

def new_deconstruct(self):
  name, path, args, kwargs = original_deconstruct(self)
  for attr in IGNORED_ATTRS:
    kwargs.pop(attr, None)
  return name, path, args, kwargs

models.Field.deconstruct = new_deconstruct
