There are multiple scenario, where the DataGroupUserGroup
of a data group
needs to be updated. E.g. when a user has been removed from the list of owners
of the data group itself, or from one of it’s parent DataGroup
s (see
Remove an owner from a parent DataGroup workflow for instance).
To efficiently refresh the owners of the data group, we need to query the
DataGroupUserGroup
s of all it’s parents and add the resulting users to
the DataGroupUserGroup
of the DataGroup
that is about to be refreshed.
Using the DataGroupNode
relations implemented with django-postgresql-dag,
we can get all owners of the parents with one single database transaction and
synchronize the DataGroupUserGroup
with this list.
The figure Sequence Diagram to refresh the owners of a DataGroup illustrates this workflow.
