The generic relations allow us to create row level permissions with any instance of any model and connect it to an "owner" object. To allow more freedom, the owner object is also a generic relation. This means that you can use your own models as an owner of a row level permission. The actual model code is below: 3 The row-level permissions system uses generic relations to decrease the number of tables to only one.
