    <p>You can change your Project factory a little bit:</p> <p><strong>updated after comment</strong></p> <pre><code>angular.module('mongolab', ['ngResource']). factory('Project', function($resource) { var ProjectApi = $resource('https://api.mongolab.com/api/1/databases' + '/villes/collections/universities/:id', {apiKey: '7pcSaEmpVzZ90V6CVggeHa6Ys71uaZOA'}, { update: {method: 'PUT'} } ); var Project = function(data) { angular.extend(this, data); }; Project.query = ProjectApi.query; Project.get = ProjectApi.get; Project.prototype.update = function(cb) { return ProjectApi.update({id: this._id.$oid}, angular.extend(this, {_id: undefined}), cb); }; Project.prototype.destroy = function(cb) { return ProjectApi.remove({id: this._id.$oid}, cb); }; return Project; }); </code></pre> <p>In <code>EditCtrl</code> you make a strange thing: </p> <pre><code>function EditCtrl($scope, $location, $routeParams, Project) { var self = this; // Project is already defined in arguments and it is a service var Project = Project.instance(); } </code></pre> <p>Calling <code>Project.instance()</code> will return you plain resource object that doesn't have any update() method! Look at your code in Project factory.</p> <p>Also change code in EditCtrl:</p> <pre><code>function EditCtrl($scope, $location, $routeParams, Project) { var self = this; Project.get({id: $routeParams.projetId}, function(projet) { self.original = projet; $scope.projet = new Project(self.original); }); $scope.save = function() { $scope.projet.update(function() { $location.path('/list'); }); }; } </code></pre> <p>And finally you will have it working.</p> <p>See <a href="http://plnkr.co/edit/tOmMu81ApyfSHM1lniVz?p=preview" rel="nofollow">plunker</a></p>

    1. COThis is how i builded my code at first before changing it. The problem with this code is, when i try to display the data of each record with `<div ng-repeat="(key, val) in projet"><div>{{key}}:{{val}}</div> </div>` i have 2 extra lines : update and destroy (see in the "editer" view), but i just want to display the mongolab fields (id, name, rang)

    2. COI've updated `Project` factory in my answer. Of course, it's only a way to do so. I think this nice thread about prototype in javascript will be helpful too http://stackoverflow.com/questions/572897/how-does-javascript-prototype-work .

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
