I'm working on a blog like structured web app In AngularJS. Im trying to retrieve the user which is an other of a post and retrieve their display name dynamically as it loops through all the posts but I cant seem to retrieve data correctly.. This is what I have done so far.
Blog Controller:
uno.controller('newsCtrl', function($scope, $http, adbFactory){
$scope.derp = 'derp!!!!!';
adbFactory.get($http, 'get users 1', false).success(function(data){
$scope.user = data;
}).error(function(){
console.log('Errorrr');
});
$scope.init = function(){
adbFactory.get($http, 'get all blog_posts', true).success(function(data){
$scope.posts = data;
console.log($scope.posts);
});
};
$scope.getAuthor = function(_id) {
adbFactory.get($http, 'get users id ' +_id+ ' spec', false).success(function(data){
//$scope.author = data;
//console.log($scope.author);
return data;
});
};
});
If I console.log the data it shows the users perfectly given the author id which is in the database, but when i attempt to call the getAuthor function using the '{{ }}' scope i get a collage of errors... heres my blog template below.
Blog Template:
<div class="large-12 small-12 columns" ng-init="init()">
<div class="row">
<div class="large-12 small-12 columns" ng-repeat="topic in posts" style="margin-bottom:20px;">
<div id="news-post" class="panel animated fadeInUp">
<div class="row" ng-init="getAuthor(topic.author_id)">
<div class="large-2 small-2 columns">
<img src="{{ topic['thumb'] }}" alt="" style="border-radius:50%; height:100px; width: 150px;" />
</div>
<div class="left large-10 small-10 columns">
<div class="row">
<h2 class="post-title"><a href="#/news/post/{{ topic['id'] }}">{{topic['title']}}</a> <p>Posted By, {{ getAuthor(topic.author_id).email }}</p></h2>
<p>{{ topic['body'] }}</p>
</div>
</div>
</div>
</div>
</div>
<hr>
</div>
</div>
not quite sure what the problem can be.. Any thing I'm missing?
UPDATE:: I recently updated my controller and factories to get a better scope of handling my data flow, my Controller now looks like this:
uno.controller('newsCtrl', function($scope, $http, adbFactory, $cacheFactory, unoFunctions){
$scope.init = function(){
adbFactory.get($http, 'get all blog_posts', true).success(function(data){
$scope.posts = data;
$scope.getUser = function(_id) {
$scope.userData = unoFunctions.getUser(_id);
//console.log($scope.userData);
return $scope.userData;
};
});
$scope.getTags = function(_id) {
var post = unoFunctions.getPost(_id);
var _tags = post.tags.split(',');
for(var i = 0; i < _tags.length; i++)
{
_tags[i] = _tags[i].trim();
}
return _tags;
};
$scope.getUserName = function(_id) {
$scope.userData = unoFunctions.getUser(_id);
return $scope.userData.display_name;
};
$scope.getUser = function(_id) {
$scope.userData = unoFunctions.getUser(_id);
//console.log($scope.userData);
return $scope.userData;
};
$scope.getUserName = function(_id) {
$scope.userData = unoFunctions.getUser(_id);
return $scope.userData.display_name;
};
};
});
the unoFunctions factory is wht I use now to handle certain requests from my database, and that is shown below.
uno.factory('unoFunctions', function(adbFactory, $http, $cacheFactory){ var fact = {};
var user = $cacheFactory('user');
var post = $cacheFactory('post');
fact.getUser = function(_id) {
if(!user.get(_id)){
adbFactory.get($http, 'get users id '+_id+' spec', false).success(function(data){
user.put(_id, data);
});
}
return user.get(_id);
};
fact.getPost = function(_id) {
if(!post.get(_id))
{
adbFactory.get($http, 'get blog_posts id '+_id+' spec', false).success(function(data){
post.put(_id, data);
});
}
return post.get(_id);
};
fact.loggedIn = function()
{
console.log('gfdg');
};
/*------------------------------*/
return fact;
});
And my template to output the result is this:
<div class="large-12 small-12 columns" ng-init="init()">
<div class="row">
<div class="large-12 small-12 columns" ng-repeat="topic in posts | filter:postTitle | orderBy:'-time' " style="margin-bottom:20px;">
<div id="news-post" class="panel animated fadeInUp" ng-init="getTags(topic.id)">
<div class="row" style="padding-bottom:0px;">
<div class="large-2 small-2 columns">
<img src="{{ topic['thumb'] }}" alt="" style="border-radius:50%; height:120px; width: 200px;" />
</div>
<div class="left large-10 small-10 columns">
<div class="row" style="padding-bottom:0px;">
<h2 class="post-title">
<a href="#/news/post/{{ topic['id'] }}">
{{topic['title']}}
</a>
<p style="font-size:13px; font-style:italic; color:#a5a5a5" class="right">{{ topic.time | timeago }} {{ }}</p>
<p style="font-weight:bold; font-style:italic; color:#aaa">Posted By, {{ getUser(topic.author_id).display_name }}</p></h2>
<p>{{ topic['body'] }}</p>
<div ng-repeat="tag in getTags(topic.id)"><span style="background:#ccc; margin:7px; padding:4px; border-radius:5px; font-size:12px" class="left">{{ tag }}</span></div>
<p class="right" style="background:#dedede; font-size:13px; padding:7px; border-radius:6px; color:#1985A1;">{{ topic.category }}</p
</div>
</div>
</div>
</div>
</div>
</div>
</div>
This works fine and returns the required results I'm looking for but I wish to get rid of the countless Error: [$rootScope:infdig] errors and keep my console clean.. I researched the error and it seems to be because when I call functions from the unoFunctions factory like, getUser, or getPost. it returns a new array each time or something like that which I guess throws things out of scope. I'm not entirely sure, and reason for this?
