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

Examples:

Bind the document.

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

Parameters:

  • options (Hash) —

    The options to pass through.

Since:

  • 2.0.0.rc.1

  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

Parameters:

  • options (Hash) —

    The options to pass through.
