django.db.migrations.exceptions.InconsistentMigrationHistory

Question

When I run python manage.py migrate on my Django project, I get the following error:

Traceback (most recent call last):
File \"manage.py\", line         


        

Answer 1

The order of INSTALLED_APPS seems important. If you always put your recent works on top/beginning of the list they'll always be loaded properly in regard to django.contrib.admin. Moving my works to the beginning of the INSTALLED_APPS list fixed this problem for me. The reason Kun Shi's solution may have worked maybe it ran the migrations in a different order.

Answer 2

when you create a new Django project and run

python manage.py migrate

The Django will create 10 tables for you by default including one auth_user table and two start with auth_user.

when you want to create a custom user model inherit from AbstractUser, you will encounter this problem with error message as follow:

django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency account.0001_initial on database 'default'.

I solve this problem by dropping my entire database, and create a new one. And this replaced the three tables I mentioned.

Answer 3

If you set AUTH_USER_MODEL in settings.py like this:

AUTH_USER_MODEL = 'custom_user_app_name.User'

you should comment this line before run makemigration and migrate commands. Then you can uncomment this line again.

Answer 4

Here how to solve this properly.

Follow these steps in your migrations folder inside the project:

1. Delete the _pycache_ and the 0001_initial files.
2. Delete the db.sqlite3 from the root directory (be careful all your data will go away).
3. on the terminal run:
   python manage.py makemigrations
   python manage.py migrate

Voila.

Answer 5

just delete the sqlite file or run flush the databse 'python manage.py flush' and then run makemigrations and migrate commands respectively.

Answer 6

If you are working on an empty database a quick fix could be running the migrations for the account app, before any other app migrations.

$ ./manage.py migrate account

And then:

$ ./manage.py migrate
