Can't get shortcut "admin" rule to work

[lafrech]

Hi.

Here's another of my 0.26 migration issues.

I have a set of auth rules based on a SQLAlchemy relationship model and I use a shortcut "admin" rule to specify that admin users (users with is_admin property set to True) can do everything.

# Admin can do anything
allow(user: User, _action, _resource) if user.is_admin = true;

This worked fine until 0.26 / SqlAlchemyAdapter. Now, I have issues with authorized_query not returning all expected rows.

Here's a 0.25 query:

SELECT anon_1.timeseries_id AS anon_1_timeseries_id, anon_1.timeseries_cluster_id AS anon_1_timeseries_cluster_id, anon_1.timeseries_data_state_id AS anon_1_timeseries_data_state_id 
FROM (SELECT timeseries.id AS timeseries_id, timeseries.cluster_id AS timeseries_cluster_id, timeseries.data_state_id AS timeseries_data_state_id 
FROM timeseries 
WHERE true UNION SELECT timeseries.id AS timeseries_id, timeseries.cluster_id AS timeseries_cluster_id, timeseries.data_state_id AS timeseries_data_state_id 
FROM timeseries 
WHERE timeseries.cluster_id IN (__[POSTCOMPILE_cluster_id_1])) AS anon_1

And here's the equivalent 0.26 query:

SELECT DISTINCT timeseries.id AS timeseries_id, timeseries.cluster_id AS timeseries_cluster_id, timeseries.data_state_id AS timeseries_data_state_id 
FROM timeseries JOIN timeseries_clusters ON timeseries.cluster_id = timeseries_clusters.id JOIN timeseries_cluster_groups ON timeseries_clusters.group_id = timeseries_cluster_groups.id JOIN timeseries_cluster_groups_by_users ON timeseries_cluster_groups.id = timeseries_cluster_groups_by_users.timeseries_cluster_group_id JOIN users ON timeseries_cluster_groups_by_users.user_id = users.id 
WHERE true OR users.id = %(id_1)s

The issue seems to be that the "admin" shortcut (WHERE true) is only used after the joins needed for the relational rule.

In the case above, the query returns no row because the admin user has no relation to the timeseries objects. If I add an unrelated user with relations to timeseries objects, then, thanks to the admin shortcut, those timeseries are returned.

Basically, the "admin" shortcut is broken as it only returns the rows for which at least a user exists that fills the rule.

[oso][info]   }
[oso][info]     RULE: allow(_actor, _action, _resource) if OpenBarPolarClass.get() = _value_1 and _value_1;

In both traces, the admin shortcut line gives the following result:

[oso][info]   RESULT: {
[oso][info]     resource: _this matches Timeseries{}
[oso][info]   }

and the relational line

[oso][info]   RESULT: {
[oso][info]     resource: _this.cluster.group matches TimeseriesClusterGroup{} and _this.cluster matches TimeseriesCluster{} and _this matches Timeseries{} and _tscgbu_492 in _this.cluster.group.timeseries_cluster_groups_by_users and <User Chuck <[email protected]>, admin: True, active: True> TYPE `User` = _tscgbu_492.user
[oso][info]   }

The first result should allow the query to return all Timeseries. The generated query should then be

SELECT DISTINCT timeseries.id AS timeseries_id, timeseries.cluster_id AS timeseries_cluster_id, timeseries.data_state_id AS timeseries_data_state_id 
FROM timeseries

Or am I getting/doing this wrong?
