I'm new to AngularJS. I've researched the theory behind ng-repeats but I cannot find any good examples of 2-way data binding or object creation for nested ng-repeats. I understand that the syntax has changed in recent versions. I'm using 1.1.5.
I have post objects that have a nested array of comment objects. I want to be able to add new comment objects to the array of comments in the post. I've tried lots of different versions.
This is my HTML:
<div id='posts' ng-controller="PostsCtrl">
<ul>
<div id='post' ng-repeat="post in posts track by post.id">
<div id='postMedia'>
<img ng-click="" ng-src={{post.attachment}} />
</div>
<div ng-click="">
<div ng-click="">{{post.message}}</div>
<div ng-click="">{{post.created_at}}</div>
</div>
<h1>Comments</h1>
<div id='comment' ng-repeat="comment in post.comments track by post.comment.id">
<div ng-click="">{{comment.body}}</div>
</div>
<form ng-submit="addComment()">
<input id="body" type="text" placeholder="Reply…" ng-model="post.comment.body">
<input type="submit" value="Add">
</form>
</div>
</ul>
</div>
This is the controller:
myApp.controller('PostsCtrl', ['$scope', 'angularFire',
function MyCtrl($scope, angularFire) {
var url = 'https://inviter-dev.firebaseio.com/posts';
$scope.items = angularFire(url, $scope, 'posts', {});
$scope.commentProp = 'comments';
$scope.addComment = function() {
$scope.comments.push($scope.newcomment);
}
}
]);
SOLUTION:
Thanks to Chandermani answer for solving this. I modified the controller slightly because I wanted the to use a key called body in the data store -
myApp.controller('PostsCtrl', ['$scope', 'angularFire',
function MyCtrl($scope, angularFire) {
var url = 'https://inviter-dev.firebaseio.com/posts';
$scope.items = angularFire(url, $scope, 'posts', [] );
$scope.addComment = function(post,comment) {
post.comments.push({body:comment});
}
}
]);
