Method Details

attributes() public method

This method must be overridden by child classes to define available attributes. Note: primary key attribute "_id" should be always present in returned array. For example: php public function attributes() { return ['_id', 'name', 'address', 'status']; }

public attributes ( ) : array
return	array	list of attribute names.

collectionName() public static method

Collection name can be either a string or array: - if string considered as the name of the collection inside the default database. - if array - first element considered as the name of the database, second - as name of collection inside that database By default this method returns the class name as the collection name by calling [[Inflector::camel2id()]]. For example, 'Customer' becomes 'customer', and 'OrderItem' becomes 'order_item'. You may override this method if the collection is not named after this convention.

public static collectionName ( ) : string \| array
return	string \| array	the collection name

delete() public method

This method performs the following steps in order: 1. call [[beforeDelete()]]. If the method returns false, it will skip the rest of the steps; 2. delete the document from the collection; 3. call [[afterDelete()]]. In the above step 1 and 3, events named [[EVENT_BEFORE_DELETE]] and [[EVENT_AFTER_DELETE]] will be raised by the corresponding methods.

public delete ( ) : integer \| boolean
return	integer \| boolean	the number of documents deleted, or false if the deletion is unsuccessful for some reason. Note that it is possible the number of documents deleted is 0, even though the deletion execution is successful.

deleteAll() public static method

WARNING: If you do not specify any condition, this method will delete documents rows in the collection. For example, to delete all customers whose status is 3: php Customer::deleteAll(['status' => 3]);

public static deleteAll ( array $condition = [], array $options = [] ) : integer
$condition	array	description of the objects to delete. Please refer to [[Query::where()]] on how to specify this parameter.
$options	array	list of options in format: optionName => optionValue.
return	integer	the number of documents deleted.

deleteInternal() protected method

equals() public method

The comparison is made by comparing the collection names and the primary key values of the two active records. If one of the records [[isNewRecord|is new]] they are also considered not equal.

public equals ( ActiveRecord $record ) : boolean
$record	ActiveRecord	record to compare to
return	boolean	whether the two active records refer to the same row in the same Mongo collection.

find() public static method

public static find ( ) : ActiveQuery
return	ActiveQuery	the newly created [[ActiveQuery]] instance.

getCollection() public static method

Return the Mongo collection instance for this AR class.

public static getCollection ( ) : Collection
return	Collection	collection instance.

getDb() public static method

By default, the "mongodb" application component is used as the Mongo connection. You may override this method if you want to use a different database connection.

public static getDb ( ) : Connection
return	Connection	the database connection used by this AR class.

insert() public method

This method performs the following steps in order: 1. call [[beforeValidate()]] when $runValidation is true. If validation fails, it will skip the rest of the steps; 2. call [[afterValidate()]] when $runValidation is true. 3. call [[beforeSave()]]. If the method returns false, it will skip the rest of the steps; 4. insert the record into collection. If this fails, it will skip the rest of the steps; 5. call [[afterSave()]]; In the above step 1, 2, 3 and 5, events [[EVENT_BEFORE_VALIDATE]], [[EVENT_BEFORE_INSERT]], [[EVENT_AFTER_INSERT]] and [[EVENT_AFTER_VALIDATE]] will be raised by the corresponding methods. Only the [[dirtyAttributes|changed attribute values]] will be inserted into database. If the primary key is null during insertion, it will be populated with the actual value after insertion. For example, to insert a customer record: php $customer = new Customer(); $customer->name = $name; $customer->email = $email; $customer->insert();

public insert ( boolean $runValidation = true, array $attributes = null ) : boolean
$runValidation	boolean	whether to perform validation before saving the record. If the validation fails, the record will not be inserted into the collection.
$attributes	array	list of attributes that need to be saved. Defaults to null, meaning all attributes that are loaded will be saved.
return	boolean	whether the attributes are valid and the record is inserted successfully.

insertInternal() protected method

primaryKey() public static method

The default implementation will return ['_id']. Note that an array should be returned even for a collection with single primary key.

public static primaryKey ( ) : string[]
return	string[]	the primary keys of the associated Mongo collection.

toArray() public method

public toArray ( array $fields = [], array $expand = [], $recursive = true )
$fields	array
$expand	array

updateAll() public static method

For example, to change the status to be 1 for all customers whose status is 2: php Customer::updateAll(['status' => 1], ['status' => 2]);

public static updateAll ( array $attributes, array $condition = [], array $options = [] ) : integer
$attributes	array	attribute values (name-value pairs) to be saved into the collection
$condition	array	description of the objects to update. Please refer to [[Query::where()]] on how to specify this parameter.
$options	array	list of options in format: optionName => optionValue.
return	integer	the number of documents updated.

updateAllCounters() public static method

For example, to increment all customers' age by 1, php Customer::updateAllCounters(['age' => 1]);

public static updateAllCounters ( array $counters, array $condition = [], array $options = [] ) : integer
$counters	array	the counters to be updated (attribute name => increment value). Use negative values if you want to decrement the counters.
$condition	array	description of the objects to update. Please refer to [[Query::where()]] on how to specify this parameter.
$options	array	list of options in format: optionName => optionValue.
return	integer	the number of documents updated.
