An Eloquent model and Query builder with support for MongoDB, inspired by LMongo, but using the original Laravel methods. This library extends the original Laravel classes, so it uses exactly the same methods.
Add the package to your composer.json and run composer update.
{
"require": {
"jenssegers/mongodb": "*"
}
}
Add the service provider in app/config/app.php:
'Jenssegers\Mongodb\MongodbServiceProvider',
The service provider will register a mongodb database extension with the original database manager. There is no need to register additional facades or objects. When using mongodb connections, Laravel will automatically provide you with the corresponding mongodb objects.
Change your default database connection name in app/config/database.php:
'default' => 'mongodb',
And add a new mongodb connection:
'mongodb' => array(
'driver' => 'mongodb',
'host' => 'localhost',
'port' => 27017,
'username' => 'username',
'password' => 'password',
'database' => 'database'
),
You can connect to multiple servers or replica sets with the following configuration:
'mongodb' => array(
'driver' => 'mongodb',
'host' => array('server1', 'server2),
'port' => 27017,
'username' => 'username',
'password' => 'password',
'database' => 'database',
'options' => array('replicaSet' => 'replicaSetName')
),
Tell your model to use the MongoDB model and set the collection (alias for table) property. The lower-case, plural name of the class will be used for the collection name, unless another name is explicitly specified.
use Jenssegers\Mongodb\Model as Eloquent;
class MyModel extends Eloquent {
protected $collection = 'mycollection';
}
You can also specify the connection name in the model by changing the connection property.
Everything else works just like the original Eloquent model. Read more about the Eloquent on http://laravel.com/docs/eloquent
The database driver plugs right into the original query builder. When using mongodb connections you will be able to build fluent queries to perform database operations. For your convenience, there is a collection alias for table as well as some additional mongodb specific operations like push and pull.
// With custom connection
$user = DB::connection('mongodb')->collection('users')->get();
// Using default connection
$users = DB::collection('users')->get();
$user = DB::collection('users')->where('name', 'John')->first();
Read more about the query builder on http://laravel.com/docs/queries
The database driver also has (limited) schema builder support. You can easily manipulate collections and set indexes:
Schema::create('users', function($collection)
{
$collection->index('name');
$collection->unique('email');
});
Supported operations are:
- create and drop
- collection
- hasCollection
- index and dropIndex (compound indexes supported as well)
- unique
- background, sparse, expire (MongoDB specific)

The MongoDB session driver is available in a separate package, check out https://github.com/jenssegers/Laravel-MongoDB-Session
Retrieving All Models
$users = User::all();
Retrieving A Record By Primary Key
$user = User::find('517c43667db388101e00000f');
Wheres
$users = User::where('votes', '>', 100)->take(10)->get();
Or Statements
$users = User::where('votes', '>', 100)->orWhere('name', 'John')->get();
Using Where In With An Array
$users = User::whereIn('age', array(16, 18, 20))->get();
When using whereNotIn objects will be returned if the field is non existant. Combine with whereNotNull('age') to leave out those documents.
Using Where Between
$users = User::whereBetween('votes', array(1, 100))->get();
Where null
$users = User::whereNull('updated_at')->get();
Order By
$users = User::orderBy('name', 'desc')->get();
Offset & Limit
$users = User::skip(10)->take(5)->get();
Distinct
Distinct requires a field for which to return the distinct values.
$users = User::distinct()->get(array('name'));
// or
$users = User::distinct('name')->get();
Distinct can be combined with where:
$users = User::where('active', true)->distinct('name')->get();
Advanced Wheres
$users = User::where('name', '=', 'John')->orWhere(function($query)
{
$query->where('votes', '>', 100)
->where('title', '<>', 'Admin');
})
->get();
Group By
Selected columns that are not grouped will be aggregated with the $last function.
$users = Users::groupBy('title')->get(array('title', 'name'));
Aggregation
Aggregations are only available for MongoDB versions greater than 2.2.
$total = Order::count();
$price = Order::max('price');
$price = Order::min('price');
$price = Order::avg('price');
$total = Order::sum('price');
Aggregations can be combined with where:
$sold = Orders::where('sold', true)->sum('price');
Like
$user = Comment::where('body', 'like', '%spam%')->get();
Incrementing or decrementing a value of a column
Perform increments or decrements (default 1) on specified attributes:
User::where('name', 'John Doe')->increment('age');
User::where('name', 'Jaques')->decrement('weight', 50);
The number of updated objects is returned:
$count = User->increment('age');
You may also specify additional columns to update:
User::where('age', '29')->increment('age', 1, array('group' => 'thirty something'));
User::where('bmi', 30)->decrement('bmi', 1, array('category' => 'overweight'));
All basic insert, update, delete and select methods should be implemented.
Supported relations are:
- hasOne
- hasMany
- belongsTo
Example:
use Jenssegers\Mongodb\Model as Eloquent;
class User extends Eloquent {
public function items()
{
return $this->hasMany('Item');
}
}
And the inverse relation:
use Jenssegers\Mongodb\Model as Eloquent;
class Item extends Eloquent {
public function user()
{
return $this->belongsTo('User');
}
}
Other relations are not yet supported, but may be added in the future. Read more about these relations on http://four.laravel.com/docs/eloquent#relationships
These expressions will be injected directly into the query.
User::whereRaw(array('age' => array('$gt' => 30, '$lt' => 40)))->get();
You can also perform raw expressions on the internal MongoCollection object, note that this will return the original response, and not a collection of models.
User::raw(function($collection)
{
return $collection->find();
});
Or you can access the internal MongoCollection object directly:
User::raw()->find();
The MongoClient and MongoDB objects can be accessed like this:
$client = DB::getMongoClient();
$db = DB::getMongoDB();
Upsert
Update or insert a document. Additional options for the update method are passed directly to the native update method.
DB::collection('users')->where('name', 'John')
->update($data, array('upsert' => true));
Push
Add an items to an array.
DB::collection('users')->where('name', 'John')->push('items', 'boots');
DB::collection('users')->where('name', 'John')->push('messages', array('from' => 'Jane Doe', 'message' => 'Hi John'));
Pull
Remove an item from an array.
DB::collection('users')->where('name', 'John')->pull('items', 'boots');
DB::collection('users')->where('name', 'John')->pull('messages', array('from' => 'Jane Doe', 'message' => 'Hi John'));
Unset
Remove one or more fields from a document.
DB::collection('users')->where('name', 'John')->unset('note');
You can also perform an unset on a model.
$user = User::where('name', 'John')->first();
$user->unset('note');
You may easily cache the results of a query using the remember method:
$users = User::remember(10)->get();
From: http://laravel.com/docs/queries#caching-queries
By default, Laravel keeps a log in memory of all queries that have been run for the current request. However, in some cases, such as when inserting a large number of rows, this can cause the application to use excess memory. To disable the log, you may use the disableQueryLog method:
DB::connection()->disableQueryLog();
