When using django today, I accidentally deleted a table in the database, and then no matter how I migrated, I couldn't migrate out of the table specified in the models. Even if the 0001_initial.py migration file in migrations is deleted and migrated again, even if the migration is successful, the table cannot be generated.
solution:
1. Find the django_migrations table in the database. If not, it will be automatically generated after all migrations in the terminal:
python manage.py migrate
2. Find the migration record corresponding to the table you deleted in the table, delete the app migration record, and save the table.
3. Re-migrate the database, although an error will be reported, but this must be available , if you forget this step, see step 6
manage.py migrate XXXapp At this point it will prompt:
django.db.utils.OperationalError: (1050, "XXX' already exists"), half the battle here.
4. Add --fake at the end of the migration command and try again
python manage.py migrate XXXapp --fake
5. The table is regenerated.
6. If still unsuccessful, as prompted:
No migrations to apply.
You can try to delete the migration records in migrations, and re-migrate (makemigrations), and then perform the above operations from scratch.
