I'm new to CoffeeScript, and I seem to be having trouble with the syntax for calling methods. Here's the Card model: <pre><code>class exports.Card extends Backbone.Model defaults: pip: '4' suit: '♠' color: 'b' rows: -> rows = '4': [2, 0, 2] rows[@pip] </code></pre> And the relevant portion of the template: <pre><code><ul class="col cols-<%= @card.rows()[0] %>"> </code></pre> which is giving me the error <code>Uncaught TypeError: Object #<Object> has no method 'rows'</code> Specifically, I'm wondering if I'm using incorrect syntax for the rows method of Card or if I'm just misunderstanding something. Thanks in advance! Update: For some reason, <code>@card.property</code> always works fine, but <code>@card.any_method()</code> never does. I've gotten around this at the moment by using properties, but I'd love it if someone was able to explain this behavior. Thanks again! Update 2: I'm using <a href="http://brunchwithcoffee.com" rel="nofollow">http://brunchwithcoffee.com</a> if it's a help to anyone, and here's the <code>main.coffee</code> file to show how the <code>@card</code> instance is being created and passed to the view. <pre><code>window.app = {} app.routers = {} app.models = {} app.collections = {} app.views = {} Card = require('models/card_model').Card MainRouter = require('routers/main_router').MainRouter HomeView = require('views/home_view').HomeView CardView = require('views/card_view').CardView # app bootstrapping on document ready $(document).ready -> app.initialize = -> app.routers.main = new MainRouter() app.views.home = new HomeView() app.views.card = new CardView(model: new Card(color: 'r', suit: '♥', pip: '7')) app.routers.main.navigate 'home', true if Backbone.history.getFragment() is '' app.initialize() Backbone.history.start() </code></pre>

Guidance

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.
