This is a clone (copy) of CSMH's declaration and methods with an added id of UnsignedBigInAutoField We should be able to delete the save_history code, but needs testing. Add error logging when capa failures happen Put StudentModuleHistory into its own database Bump out the primary key on CSMHE This gives us a gap to backfill as needed. Since the new table's pk is an unsigned bigint, even for people who don't consolidate CSMH into CSMHE, the lost rows are unlikely to matter. Remove StudentModuleHistory cleaner
