When running:

{{{
manage.py makemigrations --empty app_name
}}}

we get a file that looks like:

{{{
# Generated by Django 5.2.4 on 2025-11-10 09:23

from django.db import migrations


class Migration(migrations.Migration):

dependencies = [
("app_name", "0123_other_migration"),
]

operations = []
}}}

I find it a bit incovenient that each time, I have to remember how to add
a `RunPython` migration: this is something that happens regularly, but
probably not regularly enough to just remember it.

Is it an idea to make a template that looks like:

{{{
# Generated by Django 5.2.4 on 2025-11-10 09:23

from django.db import migrations


def forward(apps, schema_editor):
MyModel = apps.get_model('app_name', 'MyModel')

class Migration(migrations.Migration):

dependencies = [
("app_name", "0123_other_migration"),
]

operations = [
migrations.RunPython(forward)
]
}}}

This would increase productivity a bit, but I think it will also help
users not to import models directly but use the historic models at the
time of the migration (probably something that i not always done neatly).
Furthermore the migration will by default fail (since no MyModel exists,
and therefore prevents adding an empty migration to the chain).
