to_json

Importance_2
to_json(options={}) public

Returns a JSON string representing the model. Some configuration is available through options.

Options

The options are passed to the to_json method on each attribute, so the same options as the to_json methods in Active Support.

  • :only - Only include the specified attribute or list of attributes in the serialized output. Attribute names must be specified as strings.
  • :except - Do not include the specified attribute or list of attributes in the serialized output. Attribute names must be specified as strings.

Examples

  person = Person.new(:first_name => "Jim", :last_name => "Smith")
  person.to_json
  # => {"first_name": "Jim", "last_name": "Smith"}

  person.to_json(:only => ["first_name"])
  # => {"first_name": "Jim"}

  person.to_json(:except => ["first_name"])
  # => {"last_name": "Smith"}
