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';
}
If you are using a different database driver as the default one, you will need to specify the mongodb connection within your model by changing the connection property:
use Jenssegers\Mongodb\Model as Eloquent;
class MyModel extends Eloquent {
protected $connection = 'mongodb';
}
Everything else works just like the original Eloquent model. Read more about the Eloquent on http://laravel.com/docs/eloquent
You may also register an alias for the MongoDB model by adding the following to the alias array in app/config/app.php:
'Moloquent' => 'Jenssegers\Mongodb\Model',
This will allow you to use your registered alias like:
class MyModel extends Moloquent {
protected $collection = 'mycollection';
}
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 operators/operations.
// 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)
Read more about the schema builder on http://laravel.com/docs/schema
If you want to use Laravel's native Auth functionality, register this included service provider:
'Jenssegers\Mongodb\Auth\ReminderServiceProvider',
This service provider will slightly modify the internal DatabaseReminderRepository to add support for MongoDB based password reminders. If you don't use password reminders, you don't have to register this service provider and everything else should work just fine.
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 existent. 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'));
Exists
Matches documents that have the specified field.
User::where('age', 'exists', true)->get();
All
Matches arrays that contain all elements specified in the query.
User::where('roles', 'all', array('moderator', 'author'))->get();
Size
Selects documents if the array field is a specified size.
User::where('tags', 'size', 3)->get();
Regex
Selects documents where values match a specified regular expression.
User::where('name', 'regex', new MongoRegex("/.*doe/i"))->get();
Type
Selects documents if a field is of the specified type. For more information check: http://docs.mongodb.org/manual/reference/operator/query/type/#op._S_type
User::where('age', 'type', 2)->get();
Mod
Performs a modulo operation on the value of a field and selects documents with a specified result.
User::where('age', 'mod', array(10, 0))->get();
Where
Matches documents that satisfy a JavaScript expression. For more information check http://docs.mongodb.org/manual/reference/operator/query/where/#op._S_where
All basic insert, update, delete and select methods should be implemented.
Eloquent allows you to work with Carbon/DateTime objects instead of MongoDate objects. Internally, these dates will be converted to MongoDate objects when saved to the database. If you wish to use this functionality on non-default date fields you will need to manually specify them as described here: http://laravel.com/docs/eloquent#date-mutators
Example:
use Jenssegers\Mongodb\Model as Eloquent;
class User extends Eloquent {
protected $dates = array('birthday');
}
Which allows you to execute queries like:
$users = User::where('birthday', '>', new DateTime('-18 years'))->get();
Supported relations are:
- hasOne
- hasMany
- belongsTo
- belongsToMany
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');
}
}
The belongsToMany relation will not use a pivot "table", but will push id's to a related_ids attribute instead. This makes the second parameter for the belongsToMany method useless. If you want to define custom keys for your relation, set it to null:
use Jenssegers\Mongodb\Model as Eloquent;
class User extends Eloquent {
public function groups()
{
return $this->belongsToMany('Group', null, 'users', 'groups');
}
}
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
If you want to embed documents, rather than referencing them, you can use the embedsMany relation:
use Jenssegers\Mongodb\Model as Eloquent;
class User extends Eloquent {
public function books()
{
return $this->embedsMany('Book');
}
}
Now we can access the user's books through the dynamic property:
$books = User::first()->books;
When using embedded documents, there will also be an inverse relation available:
$user = $book->user;
Inserting and updating embedded documents works just like the belongsTo relation:
$book = new Book(array('title' => 'A Game of Thrones'));
$user = User::first();
$book = $user->books()->save($book);
You can remove an embedded document by using the destroy() method:
$book = $user->books()->first();
$user->books()->destroy($book->_id);
// or
$user->books()->destroy($book);
If you want to add or remove embedded documents, without persistence, you can use the associate and dissociate methods. To write the changes to the database, save the parent object:
$user->books()->associate($book);
$user->save();
Again, you may override the conventional local key by passing a second argument to the embedsMany method:
return $this->embedsMany('Book', 'local_key');
If you're using a hybrid MongoDB and SQL setup, you're in luck! The model will automatically return a MongoDB- or SQL-relation based on the type of the related model. Of course, if you want this functionality to work both ways, your SQL-models will need to extend Jenssegers\Eloquent\Model. Note that this functionality only works for hasOne, hasMany and belongsTo relations.
Example SQL-based User model:
use Jenssegers\Eloquent\Model as Eloquent;
class User extends Eloquent {
protected $connection = 'mysql';
public function messages()
{
return $this->hasMany('Message');
}
}
And the Mongodb-based Message model:
use Jenssegers\Mongodb\Model as Eloquent;
class Message extends Eloquent {
protected $connection = 'mongodb';
public function user()
{
return $this->belongsTo('User');
}
}
These expressions will be injected directly into the query.
User::whereRaw(array('age' => array('$gt' => 30, '$lt' => 40)))->get();
You can also perform raw expressions on the internal MongoCollection object. If this is executed on the model class, it will return a collection of models. If this is executed on the query builder, it will return the original response.
// Returns a collection of User models.
$models = User::raw(function($collection)
{
return $collection->find();
});
// Returns the original MongoCursor.
$cursor = DB::collection('users')->raw(function($collection)
{
return $collection->find();
});
Optional: if you don't pass a closure to the raw method, the internal MongoCollection object will be accessible:
$model = User::raw()->findOne(array('age' => array('$lt' => 18)));
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'));
If you don't want duplicate items, set the third parameter to true:
DB::collection('users')->where('name', 'John')->push('items', 'boots', true);
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();
