Migration error(Migration is applied before its dependency accounts.0001_initial on database 'default')

Question:

I’m trying to migrate my custom user model and I run makemigrations command to make migrations for new models. But when I run migrate command it throws this error :

raise InconsistentMigrationHistory(
django.db.migrations.exceptions.InconsistentMigrationHistory:
Migration admin.0001_initial is applied before its dependency
accounts.0001_initial on database ‘default’.

Trace back:

models.py

from django.contrib.auth.models import AbstractUser


class CustomUser(AbstractUser):
    """extend usermodel"""

    class Meta:
        verbose_name_plural = 'CustomUser'

I just mentioned user model in this question but still if more code is required then tell me I’ll update my question with that information. Thank you

Answers:

  1. Delete the DB
  2. Delete pycache and migrations from all the apps
  3. Make sure you have set AUTH_USER_MODEL
  4. Make migrations

I just thought I might throw in my experience with this – as a Postgres noob.

Using Postgres with the OPTIONS clause in settings.py

DATABASES = {
    'default': {
...
        'OPTIONS': {
            'options': '-c search_path=main,dev'
....
        },

It was not immediately apparent to me that Postgres searches for the table in those schema in order.

So if you are wanting to do a clean, first, initial migration into the ‘main’ schema – be sure there was no previous migration made in schema ‘dev’.

Current current migration in ‘main’ will fail because it finds mis-matched migration data in ‘dev’

Fake migrations on a project can sometimes be troubleshot using –fake

python manage.py migrate --fake
