class PlaceOS::Model::SignageTemplate::SystemTemplate

Overview

junction attaching a SignageTemplate to a ControlSystem or a Zone (exactly one of the two). A row with a #schedule shows the template during that schedule; a row without one is the default template for the pairing (at most one, enforced by a partial unique index). Surrogate UUID pk as the same template may be attached to the same system or zone multiple times with different schedules.

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

Defining the setter only once via __create_initializer__ ensures change tracking, sanitization, and custom setter blocks run uniformly across all types.

def template_id_will_change! : Nil #

Include #template_id in the set of changed attributes, whether it has changed or not.


def updated_at : Time #

#updated_at getter


def updated_at=(value : Time) #

#updated_at setter


def updated_at? : Time | Nil #

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.


def updated_at_assigned? : Bool #

junction attaching a SignageTemplate to a ControlSystem or a Zone (exactly one of the two). A row with a #schedule shows the template during that schedule; a row without one is the default template for the pairing (at most one, enforced by a partial unique index).
