copied!<p>When communicating with API, I would recommend the following approach to structuring your services (as <a href="https://stackoverflow.com/a/11850027/1095616">advised by Misko Hevery</a>):</p> <pre><code> // Author model/service angular.module('myApp').factory('Author', function($http) { var Author = function(data) { angular.extend(this, data); }; Author.get = function(id) { return $http.get('/authors/' + id).then(function(response) { return new Author(response.data); }); }; return Author; }); // Article model/service angular.module('myApp').factory('Article', function($http) { var Article = function(data) { angular.extend(this, data); }; Article.query = function() { return $http.get('/articles/').then(function(response) { var articles = []; angular.forEach(response.data, function(data){ articles.push(new Article(data)); }); return articles; }); }; return Article; }); // Your controller angular.module('myApp') .controller('Ctrl' ,[ '$scope' ,'Article' ,'Author' ,function($scope, Article, Author){ Article.query() .then(function(articles){ $scope.articles = articles; attachAuthors(articles); }); function attachAuthors(articles){ angular.forEach(articles, function(article){ Author.get(article.authorId) .then(function(author){ article.author = author; }); }); } } ] ); </code></pre> <p>But for sure, I would also advise against fetching all this data in separate calls. Instead, if possible, you should have your API return you the combined JSON. Server-side combining would be many times faster.</p>

Querying!

An individual column

Larger individual text columns get their own page to allow for proper reading.
