I am using Django 3.0.2 that is connected to a local MySQL database.My project current has 2 apps, 'accounts' and 'home'.
I dropped all the tables in my database after updating some of my model fields and I removed all the files in the migrations folder except __init__.py
. Trying to start the dev server shows an error: Dependency on app with no migrations: accounts
, so I ran python manage.py makemigrations
which returned this
Migrations for 'accounts':
accounts\migrations\0001_initial.py
- Create model User
Migrations for 'home':
home\migrations\0001_initial.py
- Create model Idea
- Create model Reply
After this, running the server gives a warning saying
You have 1 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): accounts. Run 'python manage.py migrate' to apply them.
Doing so gives me an InconsistentMigrationHistory
exception:
Migration admin.0001_initial is applied before its dependency accounts.0001_initial on database 'default'
Running python manage.py showmigrations
returns this:
accounts
[ ] 0001_initial
admin
[X] 0001_initial
[X] 0002_logentry_remove_auto_add
[X] 0003_logentry_add_action_flag_choices

[X] 0001_initial
[X] 0002_remove_content_type_name
home

I've tried runing the commands in different orders but it eventually comes to the same result. I can provide more details about the app if needed.

I hope you haven't cleared your model class. You can delete all files under migrations directory of your app directory excluding init.py file. You have to Drop table django_migrations. After you delete then run
python manage.py makemigrations account
python manage.py makemigrations home
python manage.py migrate
