class Mongoid::Relations::Bindings::Embedded::In

Binding class for embedded_in relations.

Public Instance Methods

bind_one() click to toggle source

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.

@example Bind the documents.

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

@param [ Hash ] options The binding options.

@option options [ true, false ] :continue Continue binding the inverse. @option options [ true, false ] :binding Are we in build mode?

@since 2.0.0.rc.1

def bind_one
  base.__metadata = metadata.inverse_metadata(target) unless base.__metadata
  base.parentize(target)
  binding do
    if base.embedded_many?
      target.do_or_do_not(metadata.inverse(target)).push(base)
    else
      target.do_or_do_not(metadata.inverse_setter(target), base)
    end
  end
end
unbind_one() click to toggle source

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

@example Unbind the document.

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

@param [ Hash ] options The options to pass through.

@option options [ true, false ] :continue Do we continue unbinding?
