    <p>You could have a controller class, where its constructor accepts an express object, setting up routes for you. So this is an example base <code>Controller</code> class:</p> <pre><code>/** * @param connect can either be Sencha Labs' `connect` module, or */ function Controller(express) { var self = this; var name = '/' + this._name; express.post(name, function (req, res, next) { self._create(req, res, next); }); express.get(name, function (req, res, next) { self._read(req, res, next); }); express.put(name + '/:id', function (req, res, next) { self._update(req, res, next); }); express.delete(name + '/:id', function (req, res, next) { self._delete(req, res, next); }); } // Since there aren't any protected variables in JavaScript, use // underscores to tell other programmers that `name` is protected. `name` // (or, more technically, `_name`) is still accessible, but at least, if a // team is disciplined enough, they'd know better than to access variables // with underscores in them. Controller.prototype._name = ''; Controller.prototype._create = function (req, res, next) { }; Controller.prototype._read = function (req, res, next) { }; Controller.protoype._update = function (req, res, next) { }; Controller.prototype._delete = function (req, res, next) { }; </code></pre> <p>And then, you can create a <code>Users</code> controller by extending from the <code>Controller</code> "class":</p> <pre><code>function UsersController(express) { Controller.call(this, express); } // This is not the most perfect way to implement inheritance in JavaScript, // this is one of the many ways. UsersController.prototype = Controller.prototype; UsersController.prototype._name = 'users' // An example override of the base `Controller#create` method. UsersController.prototype._create = function (req, res, next) { db.save(req.body, function (err) { if (err) res.send(500, err.message); res.redirect('/'); }); }; UsersController.prototype._read = function (req, res, next) { db.read(function (err, users) { if (err) res.send(500, err.message); res.send(users); }); }; </code></pre> <p>Once you have all the appropriate controllers declared and defined, you can start implementing them onto your express app.</p> <pre><code>// Initialize a new instance of your controller. var usersController = new UsersController(app); </code></pre> <p>P.S.: For the express calls in the constructor, there is another way to add your <code>create</code>, <code>read</code>, <code>update</code>, <code>delete</code> routes (and any other routes). I just didn't want to confuse you at first.</p> <pre><code>function Controller(express) { var name = '/' + this._name; express.post(name, this._create.bind(this)); express.get(name, this._read.bind(this)); express.put([name , ':id'].join('/'), this._update.bind(this)); express.delete([name, ':id'].join('/'), this._delete.bind(this)); }; </code></pre>

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.
