Method Details

Hide inherited methods

attributes() public abstract method

Defined in: yii\db\ActiveRecordInterface::attributes()

Returns the list of all attribute names of the record.

public abstract array attributes ( )
return array

List of attribute names.

                public function attributes();

            
delete() public abstract method

Defined in: yii\db\ActiveRecordInterface::delete()

Deletes the record from the database.

public abstract integer|boolean delete ( )
return integer|boolean

The number of rows deleted, or false if the deletion is unsuccessful for some reason. Note that it is possible that the number of rows deleted is 0, even though the deletion execution is successful.

                public function delete();

            
deleteAll() public abstract static method

Defined in: yii\db\ActiveRecordInterface::deleteAll()

Deletes records using the provided conditions.

WARNING: If you do not specify any condition, this method will delete ALL rows in the table.

For example, to delete all customers whose status is 3:

Customer::deleteAll([status = 3]);
public abstract static integer deleteAll ( $condition null )
$condition array|null

The condition that matches the records that should get deleted. Please refer to yii\db\QueryInterface::where() on how to specify this parameter. An empty condition will match all records.

return integer

The number of rows deleted

                public static function deleteAll($condition = null);

            
equals() public abstract method

Defined in: yii\db\ActiveRecordInterface::equals()

Returns a value indicating whether the given active record is the same as the current one.

Two new records are considered to be not equal.

public abstract boolean equals ( $record )
$record static

Record to compare to

return boolean

Whether the two active records refer to the same row in the same database table.

                public function equals($record);

            
find() public abstract static method

Defined in: yii\db\ActiveRecordInterface::find()

Creates an yii\db\ActiveQueryInterface instance for query purpose.

The returned yii\db\ActiveQueryInterface instance can be further customized by calling methods defined in yii\db\ActiveQueryInterface before one() or all() is called to return populated ActiveRecord instances. For example,

// find the customer whose ID is 1
$customer = Customer::find()->where(['id' => 1])->one();

// find all active customers and order them by their age:
$customers = Customer::find()
    ->where(['status' => 1])
    ->orderBy('age')
    ->all();

This method is also called by yii\db\BaseActiveRecord::hasOne() and yii\db\BaseActiveRecord::hasMany() to create a relational query.

You may override this method to return a customized query. For example,

class Customer extends ActiveRecord
{
    public static function find()
    {
        // use CustomerQuery instead of the default ActiveQuery
        return new CustomerQuery(get_called_class());
    }
}

The following code shows how to apply a default condition for all queries:

class Customer extends ActiveRecord
{
    public static function find()
    {
        return parent::find()->where(['deleted' => false]);
    }
}

// Use andWhere()/orWhere() to apply the default condition
// SELECT FROM customer WHERE `deleted`=:deleted AND age>30
$customers = Customer::find()->andWhere('age>30')->all();

// Use where() to ignore the default condition
// SELECT FROM customer WHERE age>30
$customers = Customer::find()->where('age>30')->all();
public abstract static yii\db\ActiveQueryInterface find ( )
return yii\db\ActiveQueryInterface

The newly created yii\db\ActiveQueryInterface instance.

                public static function find();

            
findAll() public abstract static method

Defined in: yii\db\ActiveRecordInterface::findAll()

Returns a list of active record models that match the specified primary key value(s) or a set of column values.

The method accepts:

  • a scalar value (integer or string): query by a single primary key value and return an array containing the corresponding record (or an empty array if not found).
  • a non-associative array: query by a list of primary key values and return the corresponding records (or an empty array if none was found). Note that an empty condition will result in an empty result as it will be interpreted as a search for primary keys and not an empty WHERE condition.
  • an associative array of name-value pairs: query by a set of attribute values and return an array of records matching all of them (or an empty array if none was found). Note that ['id' => 1, 2] is treated as a non-associative array. Column names are limited to current records table columns for SQL DBMS, or filtered otherwise to be limted to simple filter conditions.
  • a yii\db\Expression: The expression will be used directly. (@since 2.0.37)

This method will automatically call the all() method and return an array of ActiveRecord instances.

Note: As this is a short-hand method only, using more complex conditions, like ['!=', 'id', 1] will not work. If you need to specify more complex conditions, use find() in combination with where() instead.

See the following code for usage examples:

// find the customers whose primary key value is 10
$customers = Customer::findAll(10);

// the above code is equivalent to:
$customers = Customer::find()->where(['id' => 10])->all();

// find the customers whose primary key value is 10, 11 or 12.
$customers = Customer::findAll([10, 11, 12]);

// the above code is equivalent to:
$customers = Customer::find()->where(['id' => [10, 11, 12]])->all();

// find customers whose age is 30 and whose status is 1
$customers = Customer::findAll(['age' => 30, 'status' => 1]);

// the above code is equivalent to:
$customers = Customer::find()->where(['age' => 30, 'status' => 1])->all();

If you need to pass user input to this method, make sure the input value is scalar or in case of array condition, make sure the array structure can not be changed from the outside:

// yii\web\Controller ensures that $id is scalar
public function actionView($id)
{
    $model = Post::findOne($id);
    // ...
}

// explicitly specifying the colum to search, passing a scalar or array here will always result in finding a single record
$model = Post::findOne(['id' => Yii::$app->request->get('id')]);

// do NOT use the following code! it is possible to inject an array condition to filter by arbitrary column values!
$model = Post::findOne(Yii::$app->request->get('id'));
public abstract static array findAll ( $condition )
$condition mixed

Primary key value or a set of column values

return array

An array of ActiveRecord instance, or an empty array if nothing matches.

                public static function findAll($condition);

            
findOne() public abstract static method

Defined in: yii\db\ActiveRecordInterface::findOne()

Returns a single active record model instance by a primary key or an array of column values.

The method accepts:

  • a scalar value (integer or string): query by a single primary key value and return the corresponding record (or null if not found).
  • a non-associative array: query by a list of primary key values and return the first record (or null if not found).
  • an associative array of name-value pairs: query by a set of attribute values and return a single record matching all of them (or null if not found). Note that ['id' => 1, 2] is treated as a non-associative array. Column names are limited to current records table columns for SQL DBMS, or filtered otherwise to be limited to simple filter conditions.
  • a yii\db\Expression: The expression will be used directly. (@since 2.0.37)

That this method will automatically call the one() method and return an ActiveRecord instance.

Note: As this is a short-hand method only, using more complex conditions, like ['!=', 'id', 1] will not work. If you need to specify more complex conditions, use find() in combination with where() instead.

See the following code for usage examples:

// find a single customer whose primary key value is 10
$customer = Customer::findOne(10);

// the above code is equivalent to:
$customer = Customer::find()->where(['id' => 10])->one();

// find the customers whose primary key value is 10, 11 or 12.
$customers = Customer::findOne([10, 11, 12]);

// the above code is equivalent to:
$customers = Customer::find()->where(['id' => [10, 11, 12]])->one();

// find the first customer whose age is 30 and whose status is 1
$customer = Customer::findOne(['age' => 30, 'status' => 1]);

// the above code is equivalent to:
$customer = Customer::find()->where(['age' => 30, 'status' => 1])->one();

If you need to pass user input to this method, make sure the input value is scalar or in case of array condition, make sure the array structure can not be changed from the outside:

// yii\web\Controller ensures that $id is scalar
public function actionView($id)
{
    $model = Post::findOne($id);
    // ...
}

// explicitly specifying the colum to search, passing a scalar or array here will always result in finding a single record
$model = Post::findOne(['id' => Yii::$app->request->get('id')]);

// do NOT use the following code! it is possible to inject an array condition to filter by arbitrary column values!
$model = Post::findOne(Yii::$app->request->get('id'));

                public function getPrimaryKey($asArray = false);

            
getRelation() public abstract method

Defined in: yii\db\ActiveRecordInterface::getRelation()

Returns the relation object with the specified name.

A relation is defined by a getter method which returns an object implementing the yii\db\ActiveQueryInterface (normally this would be a relational yii\db\ActiveQuery object). It can be declared in either the ActiveRecord class itself or one of its behaviors.

$customer->email = $email;
$customer->insert();
public abstract boolean insert ( $runValidation true, $attributes null )
$runValidation boolean

Whether to perform validation (calling validate()) before saving the record. Defaults to true. If the validation fails, the record will not be saved to the database and this method will return false.

$attributes array|null

List of attributes that need to be saved. Defaults to null, meaning all attributes that are loaded from DB will be saved.

return boolean

Whether the attributes are valid and the record is inserted successfully.

                public function insert($runValidation = true, $attributes = null);

link() public abstract method

Defined in: yii\db\ActiveRecordInterface::link()

Establishes the relationship between two records.

The relationship is established by setting the foreign key value(s) in one record to be the corresponding primary key value(s) in the other record. The record with the foreign key will be saved into database without performing validation.

If the relationship involves a junction table, a new row will be inserted into the junction table which contains the primary key values from both records.

This method requires that the primary key value is not null.

public abstract void link ( $name, $model, $extraColumns = [] )
$name string

The case sensitive name of the relationship, e.g. orders for a relation defined via getOrders() method.

$model static

The record to be linked with the current one.

$extraColumns array

Additional column values to be saved into the junction table. This parameter is only meaningful for a relationship involving a junction table (i.e., a relation set with yii\db\ActiveQueryInterface::via()).

ngRestApiEndpoint() public abstract static method

Defines the Api Endpoint for the current Active Record model.

public abstract static string ngRestApiEndpoint ( )

                public static function ngRestApiEndpoint();

            
ngRestConfig() public abstract method

Defines the base inline configuration for the current Model.

$config luya\admin\ngrest\ConfigBuilder

ConfigBuilder Object

                public function ngRestConfig($config);

            
ngRestFind() public abstract static method

The NgRestFind is used when performing the crud list index overivew. You can override this method in order to hide data from the ngRestFind command which populates all data from the database.

An example for hidding deleted news posts from the crud list:

public static function ngRestFind()
{
    return parent::ngRestFind()->where(['is_deleted' => 0]);
}

This method will taken for all internal NOT API USER related calls. So assuming an API user makes request to the APi it will use find() instead of ngRestFind(). If a logged in user will make a request to an API it will take ngRestFind().

Also this methid is used for the admin scheduler, see {{luya\admin\models\Scheduler::triggerJob()}}.

public abstract static luya\admin\ngrest\base\NgRestActiveQuery ngRestFind ( )

                public static function ngRestFind();

            
populateRelation() public abstract method (available since version 2.0.8)

$records yii\db\ActiveRecordInterface|array|null

The related records to be populated into the relation.

                public function populateRelation($name, $records);

            
primaryKey() public abstract static method

Defined in: yii\db\ActiveRecordInterface::primaryKey()

For the primary key value see getPrimaryKey() instead.

public abstract static string[] primaryKey ( )
return string[]

The primary key name(s) for this AR class.

                public static function primaryKey();

            
save() public abstract method

Defined in: yii\db\ActiveRecordInterface::save()

Saves the current record.

This method will call insert() when isNewRecord is true, or update() when isNewRecord is false.

For example, to save a customer record:

$customer = new Customer; // or $customer = Customer::findOne($id);
$customer->name = $name;
$customer->email = $email;
$customer->save();
public abstract boolean save ( $runValidation true, $attributeNames null )
$runValidation boolean

Whether to perform validation (calling validate()) before saving the record. Defaults to true. If the validation fails, the record will not be saved to the database and this method will return false.

$attributeNames array|null

List of attribute names that need to be saved. Defaults to null, meaning all attributes that are loaded from DB will be saved.

return boolean

Whether the saving succeeded (i.e. no validation errors occurred).

                public function save($runValidation = true, $attributeNames = null);

unlink() public abstract method

Defined in: yii\db\ActiveRecordInterface::unlink()

Destroys the relationship between two records.

The record with the foreign key of the relationship will be deleted if $delete is true. Otherwise, the foreign key will be set null and the record will be saved without validation.

public abstract void unlink ( $name, $model, $delete false )
$name string

The case sensitive name of the relationship, e.g. orders for a relation defined via getOrders() method.

$model static

The model to be unlinked from the current one.

$delete boolean

Whether to delete the model that contains the foreign key. If false, the model's foreign key will be set null and saved. If true, the model containing the foreign key will be deleted.

update() public abstract method

Defined in: yii\db\ActiveRecordInterface::update()

Saves the changes to this active record into the database.

Usage example:

For example, to change the status to be 1 for all customers whose status is 2:

Customer::updateAll(['status' => 1], ['status' => '2']);
public abstract static integer updateAll ( $attributes, $condition null )
$attributes array

Attribute values (name-value pairs) to be saved for the record. Unlike update() these are not going to be validated.

$condition mixed

The condition that matches the records that should get updated. Please refer to yii\db\QueryInterface::where() on how to specify this parameter. An empty condition will match all records.

return integer

The number of rows updated

                public static function updateAll($attributes, $condition = null);
