Earlier the API endpoints related to user_group accepts and returns a
field `can_mention_group_id` which represents the ID
of user_group whose members can mention the group.
This commit renames this field to `can_mention_group`.
This commit removes "@" from name of role-based system groups
since we have added a restricion on having user group names
starting with "@" in the previous commit as they look odd in
mention syntax.
We also add a migration in this commit to update the name of
role-based system groups in existing realms to remove "@"
from the name. This migration also updates the names of
non-system user groups by removing the invalid prefixes
from their names and if there is a group already with that
name, we insted name the group as "group:{group_id}".
Fixes#26148.
This commit adds "Nobody" group option to system_user_groups_list in
settings_config.js. We do not allow can_remove_subscribers_group to
be set to "Nobody" group currently, but it is nice to add support
for this here since it will be used in more settings in future.
This commit refactors get_realm_user_groups_for_dropdown_list_widget
function to use "group_permission_settings" module instead of
passing variables like "allow_internet_group", etc. individually
for each settings.
We lose some test coverage due to this commit, but that would be
fixed when we add some more group-based settings and allow groups
other than system groups in the group based settings.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
