[Angular-Scaled Web] 7. Refactor code into Models

In the previous code, both categories and bookmarks are binded to $rootscope, or let says the same scope.

eggly-app.js:

angular.module('Eggly', [
'ui.router',
'categories',
'categories.bookmarks'
])
.config(function($stateProvider, $urlRouterProvider){
$stateProvider
.state('eggly', {
url:'',
abstract: true
//abstract: To prepend a url to all child state urls.
}); $urlRouterProvider.otherwise('/');
}) .controller('MainController', function ($scope , $state) {
$scope.categories = [
{"id": 0, "name": "Development"},
{"id": 1, "name": "Design"},
{"id": 2, "name": "Exercise"},
{"id": 3, "name": "Humor"}
]; $scope.bookmarks = [
{"id": 0, "title": "AngularJS", "url": "http://angularjs.org", "category": "Development" },
{"id": 1, "title": "Egghead.io", "url": "http://angularjs.org", "category": "Development" },
{"id": 2, "title": "A List Apart", "url": "http://alistapart.com/", "category": "Design" },
{"id": 3, "title": "One Page Love", "url": "http://onepagelove.com/", "category": "Design" },
{"id": 4, "title": "MobilityW OD", "url": "http://www.mobilitywod.com/", "category": "Exercise" },
{"id": 5, "title": "Robb Wolf", "url": "http://robbwolf.com/", "category": "Exercise" },
{"id": 6, "title": "Senor Gif", "url": "http://memebase.cheezburger.com/senorgif", "category": "Humor" },
{"id": 7, "title": "Wimp", "url": "http://wimp.com", "category": "Humor" },
{"id": 8, "title": "Dump", "url": "http://dump.com", "category": "Humor" }
]; $scope.isCreating = false;
$scope.isEditing = false;
$scope.currentCategory = null;
$scope.editedBookmark = null;     ...
...
...
})

It is not good to put those json array into the main script file. We have the file structure, which all the models are consided as common part.

It likes MVC's model.

[Angular-Scaled Web] 7. Refactor code into Models

1. So cut the data part into a spreate json file.

data/categories.json
data/bookmarks.json

bookmarks.json:

[
{"id":0, "title": "AngularJS", "url": "http://angularjs.org", "category": "Development" },
{"id":1, "title": "Egghead.io", "url": "http://angularjs.org", "category": "Development" },
{"id":2, "title": "A List Apart", "url": "http://alistapart.com/", "category": "Design" },
{"id":3, "title": "One Page Love", "url": "http://onepagelove.com/", "category": "Design" },
{"id":4, "title": "MobilityWOD", "url": "http://www.mobilitywod.com/", "category": "Exercise" },
{"id":5, "title": "Robb Wolf", "url": "http://robbwolf.com/", "category": "Exercise" },
{"id":6, "title": "Senor Gif", "url": "http://memebase.cheezburger.com/senorgif", "category": "Humor" },
{"id":7, "title": "Wimp", "url": "http://wimp.com", "category": "Humor" },
{"id":8, "title": "Dump", "url": "http://dump.com", "category": "Humor" }
]

categories.json:

[
{"id": 0, "name": "Development"},
{"id": 1, "name": "Design"},
{"id": 2, "name": "Exercise"},
{"id": 3, "name": "Humor"}
]

2. Using Serivces to create model:

Bookmarks-model.js:

angular.module('eggly.models.categories', [

])
.service('CategoriesModel', function () {
var model = this,
categories = [
{"id": 0, "name": "Development"},
{"id": 1, "name": "Design"},
{"id": 2, "name": "Exercise"},
{"id": 3, "name": "Humor"}
]; model.getCategories = function() {
return categories;
}
})
;

categories-model.js:

angular.module('eggly.models.categories', [

])
.service('CategoriesModel', function () {
var model = this,
categories = [
{"id": 0, "name": "Development"},
{"id": 1, "name": "Design"},
{"id": 2, "name": "Exercise"},
{"id": 3, "name": "Humor"}
]; model.getCategories = function() {
return categories;
}
})
;

categories.tmpl.html:

<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 categoriesListCtrl.categories" ng-class="{'active':isCurrentCategory(category)}">
<a ui-sref="eggly.categories.bookmarks({category:category.name})">
{{category.name}}
</a>
</li>
</ul>

bookmarks.tmpl.html:

<h1>{{bookmarksListCtrl.currentCategoryName}}</h1>
<div ng-class="{active: isSelectedBookmark(bookmark.id)}" ng-repeat="bookmark in bookmarksListCtrl.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>
