Django: dependencies reference nonexistent parent node creating a custom user

I am learning Django this is just a personal and local project. In the middle of development I decided to change my user to a CustomUser that I created with AbstractUser.

When typing python manage.py makemigrate

I got this error:

** I have already deleted migrations files, also the db.sqlite3 file** Can you help me to solve it? I don't want to redo it :'(

thanks

I think you're getting this error because a migration is referencing a missing migration: ('products', '0002_alter_productprice_price_favoriteproduct').

So try to:

  1. Delete all migration files except __init__.py:

  • macOS/Linux:

    find . -path "*/migrations/*.py" -not -name "__init__.py" -delete

  • Windows (Command Prompt or PowerShell):

    del /S /Q */migrations\*.py

    (Then recreate the empty __init__.py in each migrations/ folder if needed)

  1. Delete compiled files and __pycache__:

  • macOS/Linux:

    find . -name "*.pyc" -delete
find . -name "__pycache__" -type d -exec rm -r {} +

  • Windows:

    for /r %i in (*.pyc) do del "%i"
for /d /r . %d in (__pycache__) do @if exist "%d" rd /s /q "%d"

then run makemigrations and migrate commands
