Module: CurrentScope::StorableKeys

Extended by:
ActiveSupport::Concern
Included in:
RoleAssignment, ScopedRoleAssignment
Defined in:
app/models/concerns/current_scope/storable_keys.rb

Overview

One definition of the #151 key policy, shared by both assignment models.

Since the ids are string columns, an integer key and a UUID both store whole. What remains unstorable is a key that is not ONE value: a composite key is an array, and a model with no primary key names no record. A grant on either would identify the wrong row or none, so it is refused.

Instance Method Details

#current_scope_resolved_record(side) ⇒ Object

Associations cast their stored id through the target model's key type. For a legacy collapsed row that can turn a UUID-shaped string into integer record 7. Every engine path that labels or audits an existing grant uses this checked reader so an inert grant never names an unrelated live record.
