Method Details
Returns the list of all attribute names of the model.
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:
public function attributes()
{
return ['_id', 'name', 'address', 'status'];
}
public array attributes ( ) | ||
return | array | List of attribute names. |
---|---|---|
throws | \yii\base\InvalidConfigException | if not implemented |
Declares the name of the Mongo collection associated with this AR class.
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 \yii\helpers\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 string|array collectionName ( ) | ||
return | string|array | The collection name |
---|
Deletes the document corresponding to this active record from the collection.
This method performs the following steps in order:
- call \yii\mongodb\beforeDelete(). If the method returns false, it will skip the rest of the steps;
- delete the document from the collection;
- call \yii\mongodb\afterDelete().
In the above step 1 and 3, events named \yii\mongodb\EVENT_BEFORE_DELETE and \yii\mongodb\EVENT_AFTER_DELETE will be raised by the corresponding methods.
public integer|boolean delete ( ) | ||
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. |
---|---|---|
throws | \yii\db\StaleObjectException | if \yii\mongodb\optimisticLock is enabled and the data being deleted is outdated. |
throws | Exception | in case delete failed. |
Deletes documents in the collection using the provided conditions.
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:
Customer::deleteAll(['status' => 3]);
public static integer deleteAll ( $condition = [], $options = [] ) | ||
$condition | array | Description of the objects to delete. Please refer to yii\mongodb\Query::where() on how to specify this parameter. |
$options | array | List of options in format: optionName => optionValue. |
return | integer | The number of documents deleted. |
---|

protected void deleteInternal ( ) | ||
throws | \yii\db\StaleObjectException |
---|
Returns a value indicating whether the given active record is the same as the current one.
The comparison is made by comparing the collection names and the primary key values of the two active records. If one of the records \yii\mongodb\isNewRecord they are also considered not equal.
public boolean equals ( $record ) | ||
$record | yii\mongodb\ActiveRecord | Record to compare to |
return | boolean | Whether the two active records refer to the same row in the same Mongo collection. |
---|
public static yii\mongodb\ActiveQuery find ( ) | ||
return | yii\mongodb\ActiveQuery | The newly created yii\mongodb\ActiveQuery instance. |
---|
Return the Mongo collection instance for this AR class.
public static yii\mongodb\Collection getCollection ( ) | ||
return | yii\mongodb\Collection | Collection instance. |
---|
Returns the Mongo connection used by this AR class.
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 yii\mongodb\Connection getDb ( ) | ||
return | yii\mongodb\Connection | The database connection used by this AR class. |
---|
Inserts a row into the associated Mongo collection using the attribute values of this record.
This method performs the following steps in order:
- call \yii\mongodb\beforeValidate() when
$runValidation
is true. If validation fails, it will skip the rest of the steps; - call \yii\mongodb\afterValidate() when
$runValidation
is true. - call \yii\mongodb\beforeSave(). If the method returns false, it will skip the rest of the steps;
- insert the record into collection. If this fails, it will skip the rest of the steps;
- call \yii\mongodb\afterSave();
In the above step 1, 2, 3 and 5, events \yii\mongodb\EVENT_BEFORE_VALIDATE, \yii\mongodb\EVENT_BEFORE_INSERT, \yii\mongodb\EVENT_AFTER_INSERT and \yii\mongodb\EVENT_AFTER_VALIDATE will be raised by the corresponding methods.
Only the \yii\mongodb\dirtyAttributes 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:
$customer = new Customer();
$customer->name = $name;
$customer->email = $email;
$customer->insert();
public boolean insert ( $runValidation = true, $attributes = null ) | ||
$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. |
---|---|---|
throws | Exception | in case insert failed. |
See also yii\mongodb\ActiveRecord::insert().
protected void insertInternal ( $attributes = null ) | ||
$attributes |
Returns the primary key name(s) for this AR class.
The default implementation will return ['_id'].
Note that an array should be returned even for a collection with single primary key.
public static string[] primaryKey ( ) | ||
return | string[] | The primary keys of the associated Mongo collection. |
---|
Updates all documents in the collection using the provided attribute values and conditions.
For example, to change the status to be 1 for all customers whose status is 2:
Customer::updateAll(['status' => 1], ['status' => 2]);
public static integer updateAll ( $attributes, $condition = [], $options = [] ) | ||
$attributes | array | Attribute values (name-value pairs) to be saved into the collection |
$condition | array | Description of the objects to update. Please refer to yii\mongodb\Query::where() on how to specify this parameter. |
$options | array | List of options in format: optionName => optionValue. |
return | integer | The number of documents updated. |
---|
Updates all documents in the collection using the provided counter changes and conditions.
For example, to increment all customers' age by 1,
Customer::updateAllCounters(['age' => 1]);
public static integer updateAllCounters ( $counters, $condition = [], $options = [] ) | ||
$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 yii\mongodb\Query::where() on how to specify this parameter. |
$options | array | List of options in format: optionName => optionValue. |
return | integer | The number of documents updated. |
