Expose user_ids in groups for approvers list
Context
(Identified in https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/9003)
There is a UX requirement to show the members count inline with the groups selected in the "Merge request approvals" settings.
What's the problem?
::API::Entities::Group
does not provide this information. We need to expose a list of user id's so that we can calculate the count of unique members in a list of groups and users.
Options
Option 1: Form the server, expose user_ids
in ::API::Entities::Group
.
Maybe we can exclude this by default, but only expose it if a certain flag is present (i.e. ?scope=full
)?
Option 2: From the client, request group/:id/members
for each group.
This will have a noticeable performance hit on the client. We can potentially optimize this by memoizing the calls, but that also comes with a memory tradeoff on the client.
Proposal
Let's go with option 1 and expose user_ids
from ::API::Entities::Group
.
