Events

Every change triggers an event of Moodle, so it is in the site log and other plugins can observe it. All of them have the other educational level, and are written by the user who made the change.

Event	Class	Type	When
Account delegation created	\local_delegateaccount\event\delegation_created	Create	A delegation is created. Its related user is the authorised user, and other['delegateduserid'] is the delegated account
Account delegation updated	\local_delegateaccount\event\delegation_updated	Update	The period or the notification choice of a delegation changes
Account delegation revoked	\local_delegateaccount\event\delegation_revoked	Delete	A delegation is revoked. It is revoked logically and its history is kept
Session permissions changed	\local_delegateaccount\event\session_permissions_updated	Update	Permission overrides change, for the whole site, for one delegation or for many

All of them refer to the table local_delegateaccount. The event of session permissions carries how many overrides changed and, for a change of many delegations, how many delegations.

Note

The events of what a person does inside a delegated account are the ordinary ones of Moodle. They carry the real user as well, which is what the activity report reads.
