CakePHP 2.2/MongoDB 2.0.4
We all know that CakePHP is awesome, and I’m sure you’ve heard that MongoDB is pretty awesome as well.
So how do we make these awesome technologies play well together?
In an awesomely easy way :)
Let’s get things rolling by setting up MongoDB.
(Instructions for Ubuntu)
Add the following line to your php.ini file (on my system in: /etc/php5/apache2/php.ini)
This sets up PHP support for MongoDB.
Let’s install the actual DB, which is easily available through apt-get
Restart things:
… and double-check that mongo is up and running.
You should see something like: “MongoDB shell version: 2.0.4”
Now, we’ll grab the MongoDB driver for CakePHP, courtesy of Yasushi Ichikawa (ichikaway).
First, cd into your app/Plugin directory.
Then:
Once the cloning is complete you should cd into Mongodb directory and:
Now you have all the components installed and running, and it’s time to try out a simple app.
There is certain beauty in MongoDB, because it doesn’t require you to have any schema. Just write some code, and things will happen magically.
Indeed we’ll just edit our app/Config/database.php
'datasource' => 'Mongodb.MongodbSource',
'database' => 'blog',
'host' => 'localhost',
'port' => 27017,
);
Add to app/Config/bootstrap.php
Create a model:
Controller:
class PostsController extends AppController {
public function index() {
$this->set('posts', $this->Post->find('all'));
}
public function add() {
if ($this->request->is('post')) {
if ($this->Post->save($this->request->data)) {
$this->Session->setFlash('Your post has been saved.');
return $this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash('Unable to add your post.');
}
}
}
}
And a couple of views…
app/View/index.ctp
foreach ($posts as $post) {
debug($post);
}
app/View/add.ctp
Congratulations! Your first CakePHP/MongoDB app is now ready to rock.
You can go ahead and try adding some posts, and see them appear (albeit only as debug output) on the index action.
