@name Cookbook: Resources - Buzz
@description
External resources are URLs that provide JSON data, which are then rendered with the help of
templates. angular has a resource factory that can be used to give names to the URLs and then
attach behavior to them. For example you can use the
{@link http://code.google.com/apis/buzz/v1/getting_started.html#background-operations| Google Buzz API}
to retrieve Buzz activity and comments.
<doc:example>
<doc:source>
<script>
BuzzController.$inject = ['$resource'];
function BuzzController($resource){
this.Activity = $resource(
'https://www.googleapis.com/buzz/v1/activities/:userId/:visibility/:activityId/:comments',
{alt:'json', callback:'JSON_CALLBACK'},
{ get: {method:'JSON', params:{visibility:'@self'}},
replies: {method:'JSON', params:{visibility:'@self', comments:'@comments'}}
});
}
BuzzController.prototype = {
fetch: function(){
this.activities = this.Activity.get({userId:this.userId});
},
expandReplies: function(activity) {
activity.replies =
this.Activity.replies({userId:this.userId, activityId:activity.id});
}
};
</script>
<div ng:controller="BuzzController">
<input name="userId" value="googlebuzz"/>
<button ng:click="fetch()">fetch</button>
<hr/>
<div class="buzz" ng:repeat="item in activities.data.items">
<h1 style="font-size: 15px;">
<img src="{{item.actor.thumbnailUrl}}" style="max-height:30px;max-width:30px;"/>
<a href="{{item.actor.profileUrl}}">{{item.actor.name}}</a>
<a href="" ng:click="expandReplies(item)" style="float: right;">
