WE'RE USING MIGRATIONS!
|
|
|
|
If you make changes to this model, be sure to create an appropriate migration
|
|
file and check it in at the same time as your model changes. To do that,
|
|
|
|
1. Go to the mitx dir
|
|
2. ./manage.py schemamigration courseware --auto description_of_your_change
|
|
3. Add the migration file created in mitx/courseware/migrations/
