django.db.migrations.exceptions.InconsistentMigrationHistory


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 22, in <module>

File "/home/hari/project/env/local/lib/python2.7/site-     packages/django/core/management/__init__.py", line 363, in execute_from_command_line

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

I have a user model like below:

class User(AbstractUser):
    place = models.CharField(max_length=64, null=True, blank=True)
    address = models.CharField(max_length=128, null=True, blank=True)

How can I solve this problem?


Solution

  • Your django_migrations table in your database is the cause of inconsistency and deleting all the migrations just from local path won't work.

    You have to truncate the django_migrations table from your database and then try applying the migrations again. It should work but if it does not then run makemigrations again and then migrate.

    Note: don't forget to take a backup of your data.
