A node in the group tree for an authority. The tree represents the organisational hierarchy. Each group declares which subsystems (signage, events, parking, ...) it participates in via the subsystems text array; subsystem-scoped permission queries are filtered against that array. A single root per authority is enforced by a partial unique index on (authority_id) WHERE parent_id IS NULL.

Class methods

accessible_zone_ids(authority_id : String, subsystem : String, user_id : String) : Array(String)

Zone ids this user has any non-zero effective permission on, within subsystem. Includes zones reached transitively (via ancestor group membership and via ancestor zone GroupZone rows), minus anything masked off by deny rows.

Source
accessible_zones_sql(authority_id : String, subsystems : Array(String), user_id : String, required : Permissions) : String | Nil

Returns a self-contained SQL subquery (single column: zone id) yielding every zone where the user's effective permissions within any of subsystems satisfy required (Manage is a superset). The same rules as resolve_subsystem_permissions apply, but only the anchor-level grant decisions are made in Crystal (bounded by the explicit GroupUser / GroupZone rows) — the zone-subtree expansion runs in the database via a recursive CTE, so the qualifying zone set is never materialised in application memory. Returns nil when the user holds no qualifying grants (callers should treat nil as an empty set).

Source
attributes

Returns all attribute keys.

by_authority_id(id)
Source
by_parent_id(id)
Source
changes(id : UUID | Nil = nil) : ChangeFeed

Changefeed at row (if id passed) or whole table level. Returns a ChangeFeed instance which can be used to invoke async callbacks via on or use blocking Iterator via each method.

effective_permissions(authority_id : String, subsystem : String, user_id : String, zone_id : String) : Permissions

Effective permission bitmask for (user, zone) within subsystem.

Source
effective_permissions(authority_id : String, subsystem : String, user_id : String, zone_ids : Array(String)) : Permissions

Effective permissions across a batch of zones. For every zone, the closest applicable grant in that zone's own ancestry wins (replace semantics — same rule as the single-zone form). Results are OR'd across the list: this answers "what can the user do if any of these zones is in play?". Zones with no applicable grant contribute nothing. Returns Permissions::None for an empty list or for a user who can't reach any of the supplied zones.

Source
from_rs(__temp_2364 : DB::ResultSet)

Source
resolve_subsystem_permissions(authority_id : String, subsystem : String, user_id : String) : Hash(String, Permissions)

Full {zone_id => Permissions} map for the user within subsystem. Public entry point for callers that want to resolve once and cache the whole map (e.g. a per-request memo), instead of re-resolving per query.

NOTE: use getter / getter! (not property / property!) so that the setter defined later in __create_initializer__ is the only setter on the field.

A node in the group tree for an authority. The tree represents the organisational hierarchy. Each group declares which subsystems (signage, events, parking, ...) it participates in via the subsystems text array; subsystem-scoped permission queries are filtered against that array. A single root per authority is enforced by a partial unique index on (authority_id) WHERE parent_id IS NULL.

subsystems

subsystems getter

subsystems=(value : Array(String))

subsystems setter

subsystems?

NOTE: use getter / getter! (not property / property!) so that the setter defined later in __create_initializer__ is the only setter on the field. Crystal's overload resolution silently fails to replace a property-defined setter with one of identical signature for generic types (e.g. Set(String)?, Array(String)?, String | Array(String)), although it does work for non-generic ones like String?. Defining the setter only once via __create_initializer__ ensures change tracking, sanitization, and custom setter blocks run uniformly across all types.

subsystems_assigned?

A node in the group tree for an authority. The tree represents the organisational hierarchy. Each group declares which subsystems (signage, events, parking, ...) it participates in via the subsystems text array; subsystem-scoped permission queries are filtered against that array. A single root per authority is enforced by a partial unique index on (authority_id) WHERE parent_id IS NULL.

subsystems_change

Returns a Tuple of the previous and the current value of an instance variable if it has changed

subsystems_changed?

A node in the group tree for an authority. The tree represents the organisational hierarchy. Each group declares which subsystems (signage, events, parking, ...) it participates in via the subsystems text array; subsystem-scoped permission queries are filtered against that array. A single root per authority is enforced by a partial unique index on (authority_id) WHERE parent_id IS NULL.

subsystems_was

A node in the group tree for an authority. The tree represents the organisational hierarchy.
