Instance Method Details

#bind_one ⇒ Object

Binds the base object to the inverse of the association. 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 documents.

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

def bind_one
  binding do
    check_polymorphic_inverses!(_target)
    _base._association = _association.inverse_association(_target) unless _base._association
    _base.parentize(_target)
    if _base.embedded_many?
      _target.do_or_do_not(_association.inverse(_target)).push(_base)
    else
      remove_associated(_target)
      _target.do_or_do_not(_association.inverse_setter(_target), _base)
    end
  end
end

#unbind_one ⇒ Object

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

Examples:

Unbind the document.

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