def self.from_json(string_or_io : String | IO, trusted : Bool = false) : self #

def 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">

def apply_defaults #

Generate code to apply default values


def assign_attributes(params : HTTP::Params | Hash(String, String) | Tuple(String, String)) #

Assign to mulitple attributes via HTTP::Params.


def assign_attributes(model : ArangoModel::Base) #

Assign to multiple attributes from a model object

def assign_attributes_from_json(json) #

def assign_attributes_from_trusted_json(json, root : String) #

def assign_attributes_from_trusted_json(json) #

Assign each field from JSON if field exists in JSON and has changed in model


def assign_attributes_from_trusted_yaml(yaml) #

def assign_attributes_from_yaml(yaml) #

Uses the YAML parser as JSON is valid YAML


def attributes #

Returns a Hash of all attribute values


def attributes_tuple #

Returns a NamedTuple of all attribute values.


def changed? #

Check if any attributes have changed.


def changed_attributes #

Returns a Hash with all changed attributes.


def changed_json(io : IO) : Nil #

Serialize the set of changed attributes to JSON.


def changed_json : String #

Serialize the set of changed attributes to JSON.


def changed_yaml(io : IO) : Nil #

Serialize the set of changed attributes to YAML.


def changed_yaml : String #

def clear_changes_information #

Reset changes for all attributes.


def inspect #
Description copied from class Object

Returns an unambiguous and information-rich string representation of this object, typically intended for developers.

This method should usually not be overridden. It delegates to #inspect(IO) which can be overridden for custom implementations.

Also see #to_s.

def persistent_attributes #

Returns a Hash of all attributes that can be persisted.


def restore_attributes #

Reset each attribute to their previous values and clears all changes.
