For get and filter queries of NamedUserGroup, realm_for_sharding
field is used instead of realm field, as directly using
realm_for_sharding field on NamedUserGroup makes the query faster
than using realm present on the base UserGroup table.
This commit makes require_system_group and allow_internet_group
fields of GroupPermissionSetting optional with default value of
False. "allow_internet_group" is False for all of the settings
and "require_system_group" is True for only two settings, so it
is better to not having to repeat them for every setting.
This commit updates code to not pre-fetch DM permission
group settings using select_related and instead just
fetch the required data from DB when checking permission.
This will increase one query but will help in pre-fetching
the settings for all users and for all type of messages.
Fixes part of #33677.
Previously, we do not allow mentioning system user groups
at all. Now we want to use silent mention syntax for system
groups in the message sent when updating the posting permission
for a stream, so it is important to allowing silent mentioning
system groups at least. And there is no problem in allowing
silent mentions of system groups for all users.
We do not allow mentioning system groups as can_mention_group
for them is set to "Nobody" group.
id_field_name was being used only to set the initial dummy
values for realm settings. We can directly add "_id" to the
setting name instead of having an extra id_field_name field.
As we now allow anonymous groups and settings can be set to any
set of users, there is no benefit in not allowing a setting to
be set to "Owners" group.
We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
This commit introduced 'creator' and 'date_created'
fields in user groups, allowing users to view who
created the groups and when.
Both fields can be null for groups without creator data.
This commit adds a new group level setting can_manage_group
for configuring who can manage a group. This commit only adds
the field in database and make changes to automatically create
single user groups corresponsing to acting user
which will be the default value for this setting.
Fixes part of #25928.
This commit removes name, description, is_system_group and
can_mention_group fields from UserGroup model and rename
them in NamedUserGroup model.
Fixes#29554.
