An Angular JS module for Drupal 7 Services.
This Angular module makes it easy to read/write entity data to/from Drupal,
handles user authentication and registration, and makes it easy to retrieve
JSON data from Views.
Here's a very simple Angular app that loads node # 123 from Drupal and then
displays the node's title (via an alert):
// My simple app.
angular.module('myApp', ['angular-drupal']).run(['drupal', function(drupal) {
drupal.node_load(123).then(function(node) {
alert(node.title);
});
}]);
// The angular-drupal configuration settings for my simple app.
angular.module('angular-drupal').config(function($provide) {
$provide.value('drupalSettings', {
sitePath: 'http://my-drupal-site.com',
endpoint: 'api'
});
});There are two main parts to the installation and usage of this module. First, on your Drupal site you need to install the Angular Drupal module, then install and configure the Services module. Finally, include the angular-drupal module in your Angular JS application.
https://www.drupal.org/project/angular_drupal
drush dl angular_drupal
drush en -y angular_drupal
https://www.drupal.org/project/services
drush dl services
drush en -y rest_server
Then create a new endpoint by going to admin/structure/services/add with the following info:
machine name: api
server: REST
path: api
debug: unchecked
session authentication: checked
Then click the edit resources link and check the box next to each resource that should be available to your app:
comment
file
node
system
taxonomy_term
taxonomy_vocabulary
user
Then click Save. After that, click the Server tab and make sure the following boxes are checked:
json
application/json
application/x-www-form-urlencoded
multipart/form-data
Then click Save. After that flush all of Drupal's caches.
drush cc all
As usual, be sure to include the angular-drupal.js file in your app. This
typically is included via the index.html file somewhere after you include the
angular.js file:
<script src="angular-drupal.js"></script>The angular-drupal module comes with a Service called drupal. You can
include this service throughout your app using Angular's dependency injection
mechanism.
The simple app, listed above, injects the drupal service into the app's run
function. Then when the app runs it loads node # 123 from Drupal and then
alerts the node's title.
Notice how we used a config function on the angular-drupal module in the
simple app to provide the URL to our Drupal site, as well as the machine name of
the Services endpoint. Without this, the module won't know how to connect to
our Drupal site, so this must be added to our app as in the example above.
drupal.connect().then(function(data) {
if (data.user.uid) { alert('Hello ' + data.user.name + '!'); }
else { alert('Please login.'); }
});var account = {
name: 'bob',
mail: '[email protected]',
pass: 'secret'
};
drupal.user_register(account).then(function(data) {
alert('Registered user # ' + data.uid);
});drupal.user_login('bob', 'secret').then(function(data) {
if (data.user.uid) {
alert('Hello ' + data.user.name + '!');
}
});drupal.user_logout().then(function(data) {
if (!data.user.uid) {
alert('Logged out!');
}
});var node = {
type: 'article',
title: 'Hello world',
language: 'und',
body: { und: [ { value: 'How are you?' }] }
};
drupal.node_save(node).then(function(data) {
alert('Created node: ' + data.nid);
});drupal.node_load(123).then(function(node) {
alert('Loaded node: ' + node.title);
});var node = {
nid: 123,
title: 'Goodbye world',
language: 'und',
body: {
und: [ { value: 'I am fine, thank you.' }]
}
};
drupal.node_save(node).then(function(data) {
alert('Updated node: ' + data.nid);
});drupal.node_delete(123).then(function(data) {
if (data[0]) {
alert('Deleted node.');
}
});var query = {
parameters: {
'type': 'article'
}
};
drupal.node_index(query).then(function(nodes) {
var msg = '';
for (var i = 0; i < nodes.length; i++) {
var node = nodes[i];
msg += 'Loaded node: ' + node.title + '\n';
}
alert(msg);
});To create a new user account, the user must have the Administer users
permission enabled in Drupal.
var account = {
name: 'jane',
mail: '[email protected]',
pass: 'secret-sauce'
};
drupal.user_save(account).then(function(data) {
alert('Created new user #' + data.uid);
});drupal.user_load(1).then(function(account) {
alert('Loaded user: ' + account.name);
});To update an existing user account, the user must have the Change own username
or Administer users permission enabled in Drupal.
var account = {
uid: 123,
name: 'john'
};
drupal.user_save(account).then(function(data) {
alert('Name changed to: ' + data.name);
});The user must have the Administer users permission to delete a user account.
drupal.user_delete(123).then(function(data) {
if (data[0]) {
alert('Deleted user.');
}
});var query = {
parameters: {
'name': 'bob'
}
};
drupal.user_index(query).then(function(users) {
var msg = '';
for (var i = 0; i < users.length; i++) {
var user = users[i];
msg += 'Loaded user: ' + user.name + '\n';
}
alert(msg);
});var comment = {
nid: 123,
subject: 'Hello world',
comment_body: { und: [ { value: 'How are you?' } ] }
};
drupal.comment_save(comment).then(function(data) {
alert('Created comment: ' + data.cid);
});drupal.comment_load(123).then(function(comment) {
alert('Loaded comment: ' + comment.subject);
});var comment = {
cid: 456,
subject: 'Goodbye world',
comment_body: { und: [ { value: 'I am fine, thank you.' }] }
};
drupal.comment_save(comment).then(function(data) {
alert('Updated comment: ' + data.cid);
});drupal.comment_delete(123).then(function(data) {
if (data[0]) {
alert('Deleted comment.');
}
});var query = {
parameters: {
'nid': 123
}
};
drupal.comment_index(query).then(function(comments) {
var msg = '';
for (var i = 0; i < comments.length; i++) {
var comment = comments[i];
msg += 'Loaded comment: ' + comment.subject + '\n';
}
alert(msg);
});var base_64_encoded_image = 'abc...xyz';
var file = {
file: base_64_encoded_image,
filename: 'my_image.jpg',
filepath: 'public://my_image.jpg'
};
drupal.file_save(file).then(function(data) {
alert('Saved file # ' + data.fid);
});To load a file the user must have the Get any binary files permission in
Drupal.
drupal.file_load(123).then(function(file) {
alert('Loaded file: ' + file.filename);

alert(msg);
});Since this targeted action requires multipart/form-data Content-Type POSTs, it requires some setup in your controller. One way of approaching it is to create a FormData() object that gets passed into the function as the parameter 'data'. For example:
$scope.sendFile = function(nid) {
var data = {
'files[anything1]': $scope.myFile,
'field_values[anything1][alt]': $scope.imageAlt, // optional
'field_values[anything1][title]': $scope.imageAlt, // optional
field_name: 'field_images',
};
var fd = new FormData();
angular.forEach(data, function(value, key) {
fd.append(key, value);
});
drupal.file_attach(nid, fd)
.catch(function(response) {
// Some error handling.
})
.then(function(data) {
console.log(data);
// Or some other action
});
}According to comments in Services code: 'The name="files[anything]" format is required to use file_save_upload().'
In the example above, $scope.myFile is the ng-model set on the file input element. Ng-model doesn’t natively work on inputs with type=“file”, so you must use a custom directive for the model. For example:
.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};
}]);and
<input type="file" file-model="myFile"/>If you install the Views JSON module, which is available as a sub module of the Views Datasource module (https://www.drupal.org/project/views_datasource), you can easily set up a View page display to return JSON to your app:
var path = 'articles'; // The Drupal path to the Views JSON page display.
drupal.views_json(path).then(function(rows) {
angular.forEach(rows, function(row, i) {
console.log(row.title);
});
});For more information on creating Views JSON page displays, read this:
The angular-drupal module automatically takes care of the X-CSRF-Token when
it is needed. If you need to manually get the token it can easily be retrieved:
drupal.token().then(function(token) {
console.log('Got the token: ' + token);
});This module has unit test coverage to maintain quality, and welcomes comments, criticisms and pull requests.
Thank you!
