#as_json(object, opts = nil) ⇒ Hash

Serializes provided object as JSON

Parameters:

  • object (Object) —

    Serialized object

  • opts (Hash, nil) (defaults to: nil) —

    Serializer modifiers and other instantiating options

Options Hash (opts):

  • :context (Hash) —

    Serialization context

  • :many (Boolean) —

    Set true if provided multiple objects (Default ‘object.is_a?(Enumerable)`)

Returns:

  • (Hash) —

    Serialization result

def as_json(object, opts = nil)
  json = to_json(object, opts)
  config.from_json.call(json)
end

#call(object, opts = nil) ⇒ Hash

Serializes provided object to Hash

Parameters:

  • object (Object) —

    Serialized object

  • opts (Hash, nil) (defaults to: nil) —

    Serializer modifiers and other instantiating options

Options Hash (opts):

  • :context (Hash) —

    Serialization context

  • :many (Boolean) —

    Set true if provided multiple objects (Default ‘object.is_a?(Enumerable)`)

Returns:

  opts = opts ? opts.transform_keys!(&:to_sym) : {}
  self.class::CheckSerializeParams.new(opts).validate unless opts.empty?

  opts[:context] ||= {}
  serialize(object, opts)
end

#initialize(opts = nil) ⇒ Object

Instantiates new Serega class

Parameters:

  • opts (Hash, nil) (defaults to: nil) —

    Serializer modifiers and other instantiating options

Options Hash (opts):

  • :only (Array, Hash, String, Symbol) —

    The only attributes to serialize

  • :except (Array, Hash, String, Symbol) —

    Attributes to hide

  • :with (Array, Hash, String, Symbol) —

    Attributes (usually hidden) to serialize additionally

  • :validate (Boolean) —

    Validates provided modifiers (Default is true)
