Question

There are two models Groups and Students and only one table for Groups of them, the Students table was deleted.

How to make Django recreate the deleted table? If I do makemigrations it prints "No changes detected".

In django 1.7 you can try:

1. Delete your migrations folder

2. In the database: DELETE FROM django_migrations WHERE app = 'app_name'.
   You could alternatively just truncate this table.

3. python manage.py makemigrations

4. python manage.py migrate --fake

If you are working in django 1.9.5 this is the 100 % solution for this problem:

1. Delete your migrations folder

2. In the database: DELETE FROM django_migrations WHERE app = 'app_name'.
   You could alternatively just truncate this table.

3. python manage.py makemigrations app_name

4. python manage.py migrate

This works 100% for me!
