[Angular-Scaled web] 4. Using ui-router's named views

In the previous post, we use $stateProvider deriect to root url and using MainCtrl, categories.tmpl.html.

    .config(function($stateProvider){
        $stateProvider
            .state('eggly', {
                url:'/',
                controller: 'MainCtrl',
                templateUrl: 'app/categories/categories.tmpl.html'
            });
    })    

Because Categories.tmpl.html contains both categories and bookmarks, what we want is to divide categories and bookmarks into spreate views. This is benefit scaled web project.

1. Modify the categories.tmpl.html, contains only categories content

<a ng-click="setCurrentCategory(null)"><img class="logo" src="assets/img/eggly-logo.png"></a>
<ul class="nav nav-sidebar">
    <li ng-repeat="category in categories" ng-class="{'active':isCurrentCategory(category)}">
        <a ng-click="setCurrentCategory(category)">
            {{category.name}}
        </a>
    </li>
</ul>

2. Modify the bookmarks.tmpl.html,  contains only bookmarks content

<div ng-class="{active: isSelectedBookmark(bookmark.id)}"  ng-repeat="bookmark in bookmarks | filter:{category:currentCategory.name}">
    <button type="button" class="close" ng-click="deleteBookmark(bookmark)">&times;</button>
    <button type="button" class="btn btn-link" ng-click="setEditedBookmark(bookmark);startEditing();" ><span class="glyphicon glyphicon-pencil"></span>
    </button>
    <a href="{{bookmark.url}}" target="_blank">{{bookmark.title}}</a>
</div>
<hr/>
<!-- CREATING -->
<div ng-if="shouldShowCreating()">
    <button type="button" class="btn btn-link" ng-click="startCreating()">
        <span class="glyphicon glyphicon-plus"></span>
        Create Bookmark
    </button>
    <form class="create-form" ng-show="isCreating" role="form" ng-submit="createBookmark(newBookmark)" novalidate>
        <div class="form-group">
            <label for="newBookmarkTitle">Bookmark Title</label>
            <input type="text" class="form-control" id="newBookmarkTitle" ng-model="newBookmark.title" placeholder="Enter title">
        </div>
        <div class="form-group">
            <label for="newBookmarkURL">Bookmark URL</label>
            <input type="text" class="form-control" id="newBookmarkURL" ng-model="newBookmark.url" placeholder="Enter URL">
        </div>
        <button type="submit" class="btn btn-info btn-lg">Create</button>
        <button type="button" class="btn btn-default btn-lg pull-right" ng-click="cancelCreating()">Cancel</button>
    </form>
</div>
<!-- EDITING -->
<div ng-show="shouldShowEditing()">
    <h4>Editing {{editedBookmark.title}}</h4>

    <form class="edit-form" role="form" ng-submit="updateBookmark(editedBookmark)" novalidate>
        <div class="form-group">
            <label>Bookmark Title</label>
            <input type="text" class="form-control" ng-model="editedBookmark.title" placeholder="Enter title">
        </div>
        <div class="form-group">
            <label>Bookmark URL</label>
            <input type="text" class="form-control" ng-model="editedBookmark.url" placeholder="Enter URL">
        </div>
        <button type="submit" class="btn btn-info btn-lg">Save</button>
        <button type="button" class="btn btn-default btn-lg pull-right" ng-click="cancelEditing()">Cancel</button>
    </form>
</div>

3. Paste the containers of categories and bookmarks to the index.html,  add vi-view to categories and bookmarks.

        <div class="container-fluid">
<!-- paste in -->
            <div class="row">
                <div class="col-sm-3 col-md-2 sidebar" ui-view="categories">

                </div>
                <div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main" ui-view="bookmarks">

                </div>
            </div>
<!-- end-->
        </div>

4. Now need to modiy the js file to define child view.

abstract: true; which prepend a url to all child state urls: read more: https://github.com/angular-ui/ui-router/wiki/Nested-States-%26-Nested-Views#abstract-state-usage-examples,

Using $urlRouterPorvider to setup rederiect ti root url. Notice here, 'eggly' is somehow partent state. 

    .config(function($stateProvider, $urlRouterProvider){
        $stateProvider
            .state('eggly', {
                url:'',
                abstract: true
                //abstract: To prepend a url to all child state urls.
            });

        $urlRouterProvider.otherwise('/');
    })

5. Go to categories.js, add config() 

    .config(function ($stateProvider) {
        $stateProvider
            .state('eggly.categories', {
                url: '/',
               //define the child view, here we spreate the bookmarks and categories
                views: {
                    // as normal, each view can have a controller and templateUrl
                    'categories@': {
                        controller: 'CategoriesCtrl',
                        templateUrl: 'app/categories/categories.tmpl.html'
                    },
                    'bookmarks@': {
                        controller: 'BookmarksCtrl',
                        templateUrl: 'app/categories/bookmarks/bookmarks.tmpl.html'
                    }
                }
            });
    })        

6. Here, we still need to define 

CategoriesCtrl and BookmarksCtrl

    .controller('CategoriesCtrl', function ($scope) {


    })

    .controller('BookmarksCtrl', function($scope){


    })

Now we have spreate the categories and bookmarks views by using router named views. This is good scaled web project.
