Model events as relationships

simpleview_updates.md

This is my first take on providing functionality for modeling events as relationships within our views.

listenTo: function(subject, evt, observerCallback) {
  var relationshipIndex = this.get('relationshipIndex') || [],
      relationship = {
        subject: subject,
        evt: evt,
        observerCallback: observerCallback
      };
 
  subject.on(evt, observerCallback);
  this.set('relationshipIndex', relationshipIndex.push(relationship));
},
stopListening: function() {
  var relationshipIndex = this.get('relationshipIndex') || [];
      _.each(relationshipIndex, function(relationship) {
        var subject = relationship.subject, evt = relationship.evt,
          observerCallback = relationship.observerCallback;
          subject.off(evt, observerCallback);
      });
},

This article describes modeling events as relationships with Backbone and Javascript.

TODO:

• add funcitonality for monitoring if the subject is changed out with a different subject.
