This abstract class contains most of the fields (aside from the id and foreign key to StudentModule that the subclasses need to manage). It also provides a get_history method that abstracts searching across multiple backends. Move router code to openedx/core We need to use it from cms and lms. Ensure aws_migrate can be used for migrating both the lms and cms. Handle queries directed to student_module_history vs default and the extra queries generated by Django 1.8 (SAVEPOINTS, etc). Additionally, flag testing classes as multi_db so that Django will flush the non-default database between unit tests. Further decouple the foreignkey relation between csm and csmhe When calling StudentModule().delete() Django will try to delete CSMHE objects, but naively does so in the database, not by consulting the database router. Instead, we disable django cascading deletes and listen for post_delete signals and clean up CSMHE by hand. Add feature flags for CSMHE One to turn it on/off so we can control the deploy. The other will control whether or not we read from two database tables or one when searching. Update tests to explicitly use this get_history method rather than looking directly into StudentModuleHistory or StudentModuleHistoryExtended. Inform lettuce to avoid the coursewarehistoryextended app Otherwise it fails when it can't find features/ in that app. Add Pg support, this is not tested automatically.
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.
