Tuesday, March 13, 2007. Symmetric, self-referential has-one relationships in Rails. Suppose you have a Person model, and you want to represent that a Person can have a spouse. Thats a self-referential relationship the Spouse would be obviously be another Person. What makes this example a little more interesting than a standard self-referential has-one relationship is that the relationship is symmetric. You could, in theory, create the relationship from either perspective. If we have Alice and Bob.
