Error with makemigrations and migrate

[muneera_salah]

finally, I found the solution:
try to run these commands:

cd /edx/app/edxapp/edx-platform
./manage.py lms makemigrations reg_extension_form
./manage.py lms migrate reg_extension_form
sudo /edx/bin/supervisorctl restart lms

note: replace reg_extension_form with your folder name that have customization
