The previous query which uses a subquery in combination with the OR
condition results in the PG planner unable to leverage the indexes we
have available. Instead, the PG planner would loop through each user
record and execute the subquery once per row. As the number of users on
a site increases, this query becomes more and more expensive to run
leading to the query timing out once a certain threshold is reached.
In the new query, we remove the OR condition which allows the PG
planner to the existing indexes more effectively. We also improved the
subquery by removing an unnecessary join against the groups table.
Since `group_users` rows are cleaned up when a group is destroyed so there is
no need for the inner join on the `groups` table.
Adds support for polymorphic bookmarks in the serializer extensions
and preloaders for bookmarks.
Specs are skipped for now for the serializer but they do
work without the use_polymorphic_bookmark guard in the plugin.rb
After a topic is closed, the assignment is not deleted but becomes
inactive. When this happened, it was not removed from the assignments
count or list.
There is an active flag for assignments. It is used to bring assignments back when topic is reopened.
However, when assignment is inactive, it should not be displayed on assigned list or search.
Post should be always unassigned when deleted. They are hidden, and it may cause a lot of confusion. For example, when a user wants to assign topic, and it cannot be done because existing assignment to deleted post.
When topic is closed, we mark assignments as "inactive". Then when it is reopen and setting reassign_on_open is enabled, we bring back previous assignments.
We were already using custom fields for archive message and move to inbox. I changed custom fields solution to use active flag on Assignment model
When an assigned post is deleted, we should not error. For now, assignment object is left untouched to not lose information when post is `undeleted`.
We can change that behaviour later if we decide that assignments should be deleted as well.
When an assigned post is moved to the new topic, it becomes topic assignment.
When an assigned post is moved to an existing topic it stays post assignment
Change `topic_id` to polymorphic approach (In the next step we will allow assigning to individual post)
`topic_id` column is still used for efficient display of assigned users on topic list (to avoid scanning posts)
On the group assignment page, we should be able to display
- all topics assigned to that group + to user belonging to that group
- all topics assigned directly to group
- all topics assigned to individual user
Ability to assign groups.
To assign group, user must have a right to send a message to that group.
In addition, 2 jobs were introduced, - AssignNotification and UnassignNotification to inform interested users in the background about the new assignment.
- Makes a best attempt at being random and assigning people who haven’t been assigned for a long time
- Uses timezones and holidays
- Allows to define a minimum delay between assignments
- Creates a post if no one is available

Plugin triggers a N+1, and the N+1 protection breaks search
everywhere
StandardError (Attempted to access the non preloaded custom field
'assigned_to_id'. This is disallowed to prevent N+1 queries.)
