Collection represents the Mongo collection information.

A collection object is usually created by calling yii\mongodb\Database::getCollection() or yii\mongodb\Connection::getCollection().

Collection provides the basic interface for the Mongo queries, mostly: insert, update, delete operations. For example:

$collection = Yii::$app->mongodb->getCollection('customer');
$collection->insert(['name' => 'John Smith', 'status' => 1]);

Collection also provides shortcut for yii\mongodb\Command methods, such as group(), mapReduce() and so on.

To perform "find" queries, please use yii\mongodb\Query instead.

Method Details

Hide inherited methods

__call() public method

Defined in: yii\base\BaseObject::__call()

Calls the named method which is not a class method.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

public mixed __call ( $name, $params )
$name string

The method name
$params array

Method parameters
return mixed

The method return value
throws yii\base\UnknownMethodException

when calling unknown method

 

                public function __call($name, $params)
{
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call init().

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
public void __construct ( $config = [] )
$config array

Name-value pairs that will be used to initialize the object properties

 

                public function __construct($config = [])
{
    if (!empty($config)) {
        Yii::configure($this, $config);
    }
    $this->init();
}
__get() public method

Defined in: yii\base\BaseObject::__get()

Returns the value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

See also __set().

public mixed __get ( $name )
$name string

The property name
return mixed

The property value
throws yii\base\UnknownPropertyException

}
__isset() public method

Defined in: yii\base\BaseObject::__isset()

Checks if a property is set, i.e. defined and not null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).

Note that if the property is not defined, false will be returned.

    }
    return false;
}
__set() public method

Defined in: yii\base\BaseObject::__set()

Sets value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.

See also __get().

    }
}
__unset() public method

Defined in: yii\base\BaseObject::__unset()

$reduce \MongoDB\BSON\Javascript|string

Function that takes two arguments (the map key and the map values) and does the aggregation. Argument will be automatically cast to \MongoDB\BSON\Javascript.
$out string|array

Output collection name. It could be a string for simple output ('outputCollection'), or an array for parametrized output (['merge' => 'outputCollection']). You can pass ['inline' => true] to fetch the result at once without temporary collection usage.
$condition array

Criteria for including a document in the aggregation.
$options array

Additional optional parameters to the mapReduce command. Valid options include:

  • sort: array, key to sort the input documents. The sort key must be in an existing index for this collection.
  • limit: int, the maximum number of documents to return in the collection.
  • finalize: \MongoDB\BSON\Javascript|string, function, which follows the reduce method and modifies the output.
  • scope: array, specifies global variables that are accessible in the map, reduce and finalize functions.
  • jsMode: bool, specifies whether to convert intermediate data into BSON format between the execution of the map and reduce functions.
  • verbose: bool, specifies whether to include the timing information in the result information.
$execOptions array

{@see \yii\mongodb\Command::mapReduce()}
return string|array

The map reduce output collection name or output results.
throws yii\mongodb\Exception

on failure.

{
    return $this->database->createCommand()->mapReduce($this->name, $map, $reduce, $out, $condition, $options, $execOptions);
}
remove() public method

Removes data from the collection.

public integer|boolean remove ( $condition = [], $options = [], $execOptions = [] )
$condition array

Description of records to remove.
$options array

List of options in format: optionName => optionValue.
$execOptions array

{@see \yii\mongodb\Command::delete()}
return integer|boolean

Number of updated documents or whether operation was successful.
throws yii\mongodb\Exception

on failure.

 

                public function remove($condition = [], $options = [], $execOptions = [])
{
    $options = array_merge(['limit' => 0], $options);
    $writeResult = $this->database->createCommand()->delete($this->name, $condition, $options, $execOptions);
    return $writeResult->getDeletedCount();
}
save() public method

Update the existing database data, otherwise insert this data

public \MongoDB\BSON\ObjectID save ( $data, $options = [], $execOptions = [] )
$data array|object

Data to be updated/inserted.
$options array

List of options in format: optionName => optionValue.
$execOptions array

{@see \yii\mongodb\Command::insert()}
return \MongoDB\BSON\ObjectID

Updated/new record id instance.
throws yii\mongodb\Exception

on failure.

 

                public function save($data, $options = [], $execOptions = [])
{
    if (empty($data['_id'])) {
        return $this->insert($data, $options, $execOptions);
    }
    $id = $data['_id'];
    unset($data['_id']);
    $this->update(['_id' => $id], ['$set' => $data], ['upsert' => true], $execOptions);
    return is_object($id) ? $id : new ObjectID($id);
}
update() public method

Updates the rows, which matches given criteria by given data.

Note: for "multi" mode Mongo requires explicit strategy "$set" or "$inc" to be specified for the "newData". If no strategy is passed "$set" will be used.

public integer|boolean update ( $condition, $newData, $options = [], $execOptions = [] )
$condition array

Description of the objects to update.
$newData array

The object with which to update the matching records.
$options array

on failure.

 

                public function update($condition, $newData, $options = [], $execOptions = [])
{
    $writeResult = $this->database->createCommand()->update($this->name, $condition, $newData, $options, $execOptions);
    return $writeResult->getModifiedCount() + $writeResult->getUpsertedCount();
