Django Programming error column does not exist even after running migrations

Question

I run python manage.py makemigrations and I get: No changes detected Then, python manage.py migrate and I get: No migrations to apply.

Answer 1

My case might be a bit obscure, but if it helps someone, it is worth documenting here.

I was calling a function in one of my migrations, which imported a Model of said migration regularly, i.e.

from myApp.models import ModelX

The only way models should be imported in migrations would be using e.g. RunPython:

def myFunc(apps, schema_editor): 
    MyModel = apps.get_model('myApp 'MyModel')

and then calling that function like so:

class Migration(migrations.Migration):
    operations = [
        migrations.RunPython(initialize_mhs, reverse_code=migrations.RunPython.noop),
    ]

Additionally the original import worked until I modified the model in a later migration, making this error harder to locate.
