I am working on a Django project and encountered an issue when running the python manage.py migrate command. The migration process fails with the following error:

How can I resolve this error, and what changes do I need to make to migrate successfully?

Is there an alternative to index_together in newer versions of Django?

In Django version 5.1, index_together key has been removed which is mentioned in this doc.
https://docs.djangoproject.com/en/5.1/releases/5.1/
Check the Django version you are using and as well the Django docs for further reference.
