Instance Method Details

#bind_one ⇒ Object

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 association metadata on the inverse object as well as the document itself.

Examples:

Bind the document.

person.name.bind(:continue => true)
person.name = Name.new

Since:

  • 2.0.0.rc.1

def bind_one
  _target.parentize(_base)
  binding do
    _target.do_or_do_not(_association.inverse_setter(_target), _base)
  end
end

#unbind_one ⇒ Object

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

Examples:

Unbind the document.

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

Since:

  • 2.0.0.rc.1
