and CourseSectionSequence to ensure that cascading deletes will occur to delete the relation upon deletion of a foreign-keyed object. This commit is phase 3 of 4 in order to ensure a smooth deploy. The phases: 1) Add separate through models for user partition groups, add fields to point to the separate models, and start writing to those fields as well. (COMPLETE) 2) After all models have been re-generated, switch code over to use separate through model fields backed by the separate through models *and* stop writing to the original ManyToManyField field. (COMPLETE) 3) After phase 2 is deployed smoothly, remove the original ManyToManyField fields. (This PR!) 4) After phase 3 is deployed smoothly, rename the new fields to have the same name as the old fields, so new_user_partition_groups -> user_partition_groups. This PR is designed to be able to easily be rolled-back if anything goes wrong.
Open edX -------- This is the root package for Open edX. The intent is that all importable code from Open edX will eventually live here, including the code in the lms, cms, and common directories. If you're adding a new Django app, place it in core/djangoapps. If you're adding utilities that require Django, place them in core/djangolib. If you're adding code that defines no Django models or views of its own but is widely useful, put it in core/lib. Note: All new code should be created in this package, and the legacy code will be moved here gradually. For now the code is not structured like this, and hence legacy code will continue to live in a number of different packages.
