    <p>I'm new to AngularJS. In my efforts to learn, I've relied on the AngularJS tutorials. Now, I'm trying to build an app using the AngularSeed project template. I'm trying to make my project as modular as possible. For that reason, my controllers are broken out into several files. Currently, I have the following:</p> <pre><code>/app index.html login.html home.html javascript app.js loginCtrl.js homeCtrl.js </code></pre> <p>my app.js file has the following:</p> <pre><code>'use strict'; var app = angular.module('site', ['ngRoute']); app.config(function($routeProvider, $locationProvider) { $locationProvider.html5Mode(true); $routeProvider.when('/login', {templateUrl: 'app/login.html', controller:'loginCtrl'}); $routeProvider.when('/home', {templateUrl: 'app/home.html', controller:'homeCtrl'}); $routeProvider.otherwise({redirectTo: '/login'}); }); </code></pre> <p>my loginCtrl.js file is very basic at the moment. It only has:</p> <pre><code>'use strict'; app.controller('loginCtrl', function loginCtrl($scope) { } ); </code></pre> <p>My homeCtrl.js is almost the same, except for the name. It looks like the following:</p> <pre><code>'use strict'; app.controller('homeCtrl', function homeCtrl($scope) { } ); </code></pre> <p>My index.html file is the angularSeed <a href="https://github.com/angular/angular-seed/blob/master/app/index-async.html" rel="nofollow">index-async.html</a> file. However, when I load the dependencies, I have the following:</p> <pre><code>// load all of the dependencies asynchronously. $script([ 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js', 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular-route.min.js', 'javascript/app.js', 'javascript/loginCtrl.js', 'javascript/homeCtrl.js' ], function() { // when all is done, execute bootstrap angular application angular.bootstrap(document, ['site']); }); </code></pre> <p>My problem is, sometimes my app works and sometimes it doesn't. It's almost like something gets loaded before something else.</p> <p>Occasionally, I receive this <a href="http://docs.angularjs.org/error/%24injector%3amodulerr?p0=site&amp;p1=Error%3a%20%5B%24injector%3amodulerr%5D%20http://errors.angularjs.org/undefined/%24injector/modulerr?p0=ngRoute&amp;p1=Error%253A%2520No%2520module%253A%2520ngRoute%250A%2520%2520%2520%2520at%2520Error%2520%28%253Canonymous%253E%29%250A%2520%2520%2520%2520at%2520http%253A%252F%252Flocalhost%253A94%252Ftesting%252Fexample%252F%253A18%253A308%250A%2520%2520%2520%2520at%2520d%2520%28http%253A%252F%252Flocalhost%253A94%252Ftesting%252Fexample%252F%253A18%253A72%29%250A%2520%2520%2520%2520at%2520http%253A%252F%252Flocalhost%253A94%252Ftesting%252Fexample%252F%253A18%253A203%250A%2520%2520%2520%2520at%2520http%253A%252F%252Fajax.googleapis.com%252Fajax%252Flibs%252Fangularjs%252F1.2.0-rc.3%252Fangular.min.js%253A28%253A109%250A%2520%2520%2520%2520at%2520Array.forEach%2520%28native%29%250A%2520%2520%2520%2520at%2520p%2520%28http%253A%252F%252Fajax.googleapis.com%252Fajax%252Flibs%252Fangularjs%252F1.2.0-rc.3%252Fangular.min.js%253A7%253A261%29%250A%2520%2520%2520%2520at%2520e%2520%28http%253A%252F%252Fajax.googleapis.com%252Fajax%252Flibs%252Fangularjs%252F1.2.0-rc.3%252Fangular.min.js%253A28%253A48%29%250A%2520%2520%2520%2520at%2520http%253A%252F%252Fajax.googleapis.com%252Fajax%252Flibs%252Fangularjs%252F1.2.0-rc.3%252Fangular.min.js%253A28%253A126%250A%2520%2520%2520%2520at%2520Array.forEach%2520%28native%29%0A%20%20%20%20at%20Error%20%28%3Canonymous%3E%29%0A%20%20%20%20at%20http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js:6:453%0A%20%20%20%20at%20http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js:28:449%0A%20%20%20%20at%20Array.forEach%20%28native%29%0A%20%20%20%20at%20p%20%28http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js:7:261%29%0A%20%20%20%20at%20e%20%28http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js:28:48%29%0A%20%20%20%20at%20http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js:28:126%0A%20%20%20%20at%20Array.forEach%20%28native%29%0A%20%20%20%20at%20p%20%28http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js:7:261%29%0A%20%20%20%20at%20e%20%28http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js:28:48" rel="nofollow">error</a>. Other times, I get an error in the console window that says: 'Uncaught ReferenceError: app is not defined' in loginCtrl.js. Sometimes it happens with homeCtrl.js.</p> <p>What am I doing wrong? It feels like I need to have my controllers in a module and pass that module in my app.config in the app.js file. However, a) I'm not sure if that allowed and b) I'm not sure how to do it. </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
