Unable to access REST API

I'm currently working on setting up a basic RESTful API with Django Rest Framework and integrating it with AngularJS. Despite following various tutorials and learning about controllers and resources in Angular, I seem to be facing an issue in accessing JSON data correctly within my template.

app.js

var blogApp = angular.module('blogApp', ['ngResource']);

blogApp.factory('Post', ['$resource', function($resource) {
    return $resource('/api/posts/:slug/', { slug:'@slug'});
}]);

blogApp.controller('postController', ['$scope', 'Post', function($scope, Post) {
    $scope.posts = []

    Post.query().$promise.then(function(posts) {
        $scope.posts = posts;
        for (key in posts){
            console.log(posts[key]);
        }
    });
}]);

index.html ****EDIT**** I added the filter here to test, and it does do the filtering as intended, but still no text shows up in the <div>'s

<div class="container">
   <div class="col-sm-10">

      <div ng-controller="postController">
         <input type="text" ng-model="textTest">

         <div class="well" ng-repeat="(key, post) in posts | filter: textTest">
            <h1>{{ post.title }}</h1>
            {{ post.content }}
         </div>
      </div>

   </div>
</div>

The output of a GET request on /api/posts/ is shown below:

[
    {
        "url": "http://localhost:8000/api/posts/i-had-a-api-his-name-was-bingo/",
        "id": 0,
        "title": "I had a api... his name was Bingo",
        "content": "E-I-E-I-O",
        "owner": "Heather",
        "comments": "http://localhost:8000/api/posts/i-had-a-api-his-name-was-bingo/comments/"
    },
    {
        "url": "http://localhost:8000/api/posts/if-i-could-show-you-the-world/",
        "id": 1,
        "title": "If I Could Show You The World",
        "content": "It would be shining, and shimmering",
        "owner": "Heather",
        "comments": "http://localhost:8000/api/posts/if-i-could-show-you-the-world/comments/"
    },
    ...
]

Even though the correct number of boxes are displayed for each post object, the template only renders blank grey boxes without any title or content. What could be causing this issue?

EDIT: There are no errors shown in the console, and the GET request returns a status code of 200 along with application/json response. When I log $scope.posts, it displays

[Resource, Resource, Resource, Resource, Resource, Resource, Resource, $promise: Object, $resolved: true]
. Additionally,

for (key in $scope.posts){
   console.log(posts[key]);
}

prints

Resource {url: "http://localhost:8000/api/posts/i-had-a-api-his-name-was-bingo/", id: 0, title: "I had a api... his name was Bingo", content: "E-I-E-I-O", owner: "Heather"…}

Answer №1

Figuring out the solution turned out to be surprisingly simple. The issue arose because of a conflict between django-rest-framework and Django's default use of double curly braces for its variables. To resolve this confusion, I only needed to adjust the delimiter.

var app = angular.module('app', ['ngRoute'], function($interpolateProvider) {
    $interpolateProvider.startSymbol('[[');
     $interpolateProvider.endSymbol(']]');
});

After making this change, I could utilize '[[ ]]' in my templates for Angular variables. For example, [[ item.name ]])

Answer №2

Make sure to include $scope.$apply() as this function is being executed asynchronously

Answer №3

Chances are this solution will be effective.

myBlogApp.controller('articleController', ['$scope', 'Article', function($scope, Article) {
    $scope.articles = []

    Article.query().$promise.then(function(articles) {
        $scope.articles = articles;
        $scope.$apply();
    });
}]);
