title: Refactor Timelogs structure to use foreign keys.
merge_request: 8769
author:
Use normal associations instead of polymorphic. We can't properly use foreign keys on columns that are configured for polymorphic associations which has disadvantages related to data integrity and storage. Given we only use time tracking for Issues and Merge Requests we're moving to the usage of regular associations. 2017-01-25 20:16:09 -05:00			`---`
