Good question! I think the best solution would be to implement an <blockquote> EventBus aka EventDispatcher </blockquote> to coordinate all events among the different areas of your application. Going that route seems clean, loosely coupled, easy to implement, extendable and it is actually suggested by the backbone documentation, see <a href="http://documentcloud.github.com/backbone/#Events-on" rel="nofollow noreferrer">Backbone Docs</a> Please also read more on the topic <a href="http://thurloat.com/2012/01/21/backbonejs-readable-modular-testable-views" rel="nofollow noreferrer">here</a> and <a href="https://stackoverflow.com/a/7534376/358114">here</a> because (even though I tried hard) my own explanation seems kind of mediocre to me. Five step explanation: <ol> <li>Create an EventBus in your main or somewhere else as a util and include/require it <blockquote> <pre><code> var dispatcher = _.clone(Backbone.Events); // or _.extends </code></pre> </blockquote></li> <li>Add one or more callback hanlder(s) to it <blockquote> <pre><code> dispatcher.CELL_CLICK = 'cellClicked' </code></pre> </blockquote></li> <li>Add a trigger to the Eventlistener of your childView (here: the CellView) <blockquote> <pre><code> dispatcher.trigger(dispatcher.CELL_CLICK , this.model); </code></pre> </blockquote></li> <li>Add a Listener to the Initialize function of your parentView (here: the BoardView) <blockquote> <pre><code> eventBus.on(eventBus.CARD_CLICK, this.cardClick); </code></pre> </blockquote></li> <li>Define the corresponding Callback within of your parentView (and add it to your _.bindAll) <blockquote> <pre><code> cellClicked: function(model) { // do what you want with your data here console.log(model.get('someFnOrAttribute') } </code></pre> </blockquote></li> </ol>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
