As a pre-requisite for being able to query the database for objects that are expired, I need a way to express date comparison on the 'deleted_at' field which is common for every Watcher object. As they are coming from mixins, I decided to implement these filters with a syntax borrowed from the Django ORM where the field is suffixed by the comparison operator you want to apply: - The '__lt' suffix stands for 'less than' - The '__lte' suffix stands for 'less than or equal to' - The '__gt' suffix stands for 'greater than' - The '__gte' suffix stands for 'greater than or equal to' - The '__eq' suffix stands for 'equal to' I also added a 'uuid' filter to later on be able to filter by uuid. Partially Implements: blueprint db-purge-engine Change-Id: I763f330c1b8ea8395990d2276b71e87f5b3f3ddc
