Previously, realm and channel admins were not able to change settings
for a private channel they were not subscribed to. This commit changes
that.
We have only added the exception for can_add_subscribers_group
and not privacy settings.
We also need proper functions with proper terminologies for content
and metadata access.
The stream and subscription objects now have stream_post_policy value
set according to the can_send_message_group setting representing the
superset of users who have permission to post in the channel.
Since get_default_streams_for_realm_as_dicts function was only
used in tests, this commit removes it and updates the test to
use the function which returns Stream objects instead of dicts.
This commit also removes Stream.to_dict function which is no
longer used.
Clients do not use default stream groups feature now but they
should only require IDs when they use them and not the full
stream data since that is already available in streams and
subscriptions data.
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.
This commit removes the 'email_token' field from the
'Stream' model, introduces a new model 'ChannelEmailAddress',
and backfills it.
This is a prep work towards our plan to generate unique
channel emails for different users, which can be used
to check post permissions at message send time.
`is_archived` field is added to the stream and types.
Include a new `archived_channeels` client capability, to allow clients
to access data on archived channels, without breaking
backwards-compatibility for existing clients that don't know how to
handle these.
Also, included `exclude_archived` parameter to `/get-streams`,
which defaults to `true` as basic clients may not be interested
in archived streams.
In zerver/models/streams.py, updates translated string for when everyone
can post to a stream/channel to use channel instead of stream.
Part of stream to channel rename project.
Adds nullable creator field, containing a reference to the user who
created the stream. When creating a stream, acting user is set as
the creator of the stream. Since API calls to create streams always
have an acting user, this field should always be set when streams
are created using the API.
Because streams can be created with no acting user, this field is
nullable. We try to backfill existing streams using RealmAuditLog table,
but not all streams are guaranteed to have a recorded create log. Thus
this new field is left null when it cannot be backfilled. We also set
this field to null when the creator user is deleted.
