Description
The Drupal Node Reference URL Widget module helped us create references between nodes, but we had a use case that required preventing the creation of multiple pieces of reference content...this is where the Single Node Reference module came from.
It has a small admin section allowing you to choose which Node Reference fields you want to "lock down" to a single referenced piece of content. Very handy when the need arises.
