Re: Django "makemigrations -- update" donot working

['Adam Johnson' via Django developers (Contributions to Django itself)]

Indeed, David is right. The --update flag is intended for developing a
feature branch and adding extra changes to a work-in-progress migration.
This is why it requires the migration to not be applied.

Re: Django "makemigrations -- update" donot working

[David Wobrock]

Hi,

As you can see, the error message seems quite clear:
> Cannot update applied migration 'authentication.0001_initial'.
One cannot edit a migration that has already been applied.
To update it, you can undo it by running "migrate authentication zero" and
then run "makemigrations --update" again.

I do not think it's a bug in Django.

Cheers,
David

Do you need that '--update' parameter?

Django "makemigrations -- update" donot working

[Saifullah Shahen]

in my custom user model, initially, my model looks like this

class User(AbstractUser, BaseModelWithUUID):
phone = models.CharField(max_length=11, 
validators=[validate_phone_number])
I do command "makemigrations" which create a initial migration file

but after updating my model like this

class User(AbstractUser, BaseModelWithUUID):
phone = models.CharField(max_length=11, 
validators=[validate_phone_number])
name = models.CharField(max_length=255)

after adding a field "name" when i run "makemigrations --update" it shows a 
error:

CommandError: Cannot update applied migration 'authentication.0001_initial'.
