    <p>I'm playing with React for the first time and I think I really like it. I've implemented (large parts of) the board game <a href="http://en.wikipedia.org/wiki/Go_%28game%29" rel="nofollow">Go</a> with it and so far, but I've run into something strange that I don't know how to approach in the idiomatic React way. Basically, I've got a model--the board game--implemented as its own class <a href="https://github.com/cjlarose/react-go/blob/master/board.js" rel="nofollow">Board</a>. It exposes only it's constructor, and methods <code>play(i,j)</code> and <code>pass</code>. It handles all of the game logic and updates its own internal state appropriately. It has no reference to anything related to a view/component. I've got a React Component called <a href="https://github.com/cjlarose/react-go/blob/master/go.js#L24-L49" rel="nofollow">BoardView</a> which maintains a reference to an instance of a <code>Board</code>. I've also got a Component called <code>AlertView</code> that displays messages about the game state (illegal moves and such) when appropriate.</p> <p>Everything works well now, and I like the separation of concerns between the <code>Board</code> class and its views. However, the way I have my <code>Board</code> class communicate its changes to the views is unusual, and I feel that it is inconsistent with other React code. Basically, I abuse <a href="http://api.jquery.com/trigger/" rel="nofollow">jQuery's event system</a> to allow me to trigger arbitrary events like <code>["update", "atari", "suicide"]</code>. In this scheme, the Component has an onClick listener that calls <code>Board.play</code>, which triggers 0 to many events on the Board instance. The Component listens for an <code>"update"</code> event, and calls <code>this.setState</code>, which will force it to re-<code>render()</code>, putting the view into a state that correctly depicts the game. The <code>AlertView</code> listens for the <code>"atari"</code> and <code>"suicide"</code> events on the same board instance and similarly calls <code>this.setState</code>, which triggers another <code>render()</code>.</p> <p>Should I cut out the jQuery events? If so, what's the best way of doing this?</p> <p>All code is available <a href="https://github.com/cjlarose/react-go" rel="nofollow">here</a> and you can play with the app <a href="http://cjlarose.com/react-go/" rel="nofollow">here</a>.</p> <p>Edit: For posterity's sake, this question was asked at commit <a href="https://github.com/cjlarose/react-go/tree/3f600ce2d58b37a5e8637bd314ce614d27505e96" rel="nofollow">3f600c</a>.</p>

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.
