Instance Method Details

#bind(options = {}) ⇒ Object Also known as: bind_one

Binds the base object to the inverse of the relation. This is so we are referenced to the actual objects themselves on both sides.

This case sets the metadata on the inverse object as well as the document itself.

Examples:

Bind the documents.

game.person.bind(:continue => true)
game.person = Person.new

Parameters:

  • options (Hash) (defaults to: {}) —

    The binding options.

Options Hash (options):

  • :continue (true, false) —

    Continue binding the inverse.

  • :binding (true, false) —

    Are we in build mode?

Since:

  • 2.0.0.rc.1

def bind(options = {})
  inverse = metadata.inverse(target)
  base.send(metadata.foreign_key_setter, target.id)
  if metadata.inverse_type
    base.send(metadata.inverse_type_setter, target.class.model_name)
  end
  if inverse
    base.metadata = target.reflect_on_association(inverse)
    if options[:continue]
      if base.referenced_many?
        target.do_or_do_not(
          inverse, false, OPTIONS
        ).push(base, :binding => true, :continue => false)
      else
        target.do_or_do_not(
          metadata.inverse_setter(target),
          base,
          OPTIONS
        )
      end
    end
  end
end

#unbind(options = {}) ⇒ Object Also known as: unbind_one

Unbinds the base object and the inverse, caused by setting the reference to nil.

Examples:

Unbind the document.

game.person.unbind(:continue => true)
game.person = nil

Parameters:

  • options (Hash) (defaults to: {}) —

    The options to pass through.

Options Hash (options):

  • :continue (true, false) —

    Do we continue unbinding?

Since:

  • 2.0.0.rc.1
