Constructors

from_json(string_or_io : String | IO, trusted : Bool = false) : self
from_json(string_or_io : String | IO, root : String, trusted : Bool = false) : self

Deserializes the given JSON in string_or_io into an instance of self, assuming the JSON consists of an JSON object with key root, and whose value is the value to deserialize. Will not deserialise from fields with mass_assign: false

class User < ActiveModel::Model
  attribute name : String
  attribute google_id : UUID, mass_assign: false
end

User.from_json(%({"main": {"name": "Jason", "google_id": "f6f70bfb-c882-446d-8758-7ce47db39620"}}), root: "main") # => #<User:0x103131b20 @name="Jason">

created_at

created_at getter

created_at=(value : Time)

Setters created_at setter

created_at?

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.

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

created_at_changed?
