Using django 1.7.7 I want to use django\'s migration to add or remove a field. so I modified model.py and ran
python manage.py makemigrations myproj Migrations f
In my case, the migrations were not being reflected in mysql database. I manually removed the row of 'myapp'(in your case 'myproj') from the table 'django_migrations' in mysql database and ran the same commands again for migration.
