    <p><em>I use a clean backbone without wrappers or frameworks.</em></p> <p>So I create a site to manage by some products. I have two dynamic pages for this: </p> <ul> <li><code>add.php</code></li> <li><code>edit.php</code></li> </ul> <p>These pages are separate backbone applications.</p> <p>In both pages, there is an element displays a product category. Usually it is a drop-down list.</p> <p>Next, I will describe the approximate structure of my scripts. It is simple.</p> <pre><code>js +- models | +- Category.js | ... +- collections | +- Categories.js | ... +- views | +- CategoriesView.js | ... </code></pre> <p><strong>CategoryView.js</strong> contains:</p> <pre><code>App.Views.CategoriesViews = Backbone.View.extend({ template: _.template($('#tpl-categories').html()), events: { 'change select': 'toggle' }, initialize: function () { _.bindAll(this, 'render'); this.collection.on('reset', this.render); }, render: function () { this.$el .html(this.template({ collection: this.collection.toJSON() })); return this; }, toggle: function () { // Some actions here var catId = this.$el.children('select').val(); App.trigger('toggleCategories', catId); } }); </code></pre> <p><strong>Initialization</strong> of the view looks like this:</p> <pre><code>new App.Views.CategoriesViews({ el: $('#select-box-cats'), collection: new App.Collections.Categories }); </code></pre> <p>Since this element is on both pages (add.php and edit.php) it works well for both of them.</p> <p>We assume that the name of the template can be set the same on both pages:</p> <pre><code>&lt;script type="text/template" id="tpl-categories"&gt; </code></pre> <p><em>Although I think it is not a good practice.</em></p> <p><strong>Well, finally my question.</strong></p> <p>What happens if one of these pages need to add an event handler to the view. For example:</p> <pre><code>initialize: function () { _.bindAll(this, 'render', 'action'); this.collection.on('reset', this.render); this.collection.on('request', this.action); }, </code></pre> <p>I added an event to <code>request</code> collection. However, <strong>this event should not be present on another page.</strong></p> <p>What to do? To create a separate view file with the changes to the needs of the page? But it violates the principle of DRY and spawns a lot of client code!</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.
