ActiveRecord is the base class for classes representing relational data in terms of objects.

This class implements the ActiveRecord pattern for the fulltext search and data storage elasticsearch.

For defining a record a subclass should at least implement the attributes() method to define attributes. The primary key (the _id field in elasticsearch terms) is represented by getId() and setId(). The primary key is not part of the attributes.

The following is an example model called Customer:

class Customer extends \yii\elasticsearch\ActiveRecord
{
    public function attributes()
    {
        return ['id', 'name', 'address', 'registration_date'];
    }
}

You may override index() and type() to define the index and type this record represents.

Method Details

Hide inherited methods

arrayAttributes() public method

A list of attributes that should be treated as array valued when retrieved through yii\elasticsearch\ActiveQuery::fields().

If not listed by this method, attributes retrieved through yii\elasticsearch\ActiveQuery::fields() will converted to a scalar value when the result array contains only one value.

public string[] arrayAttributes ( )
return string[]

List of attribute names. Must be a subset of attributes().

 

                public function arrayAttributes()
{
    return [];
}
attributes() public method

Returns the list of all attribute names of the model.

This method must be overridden by child classes to define available attributes.

Attributes are names of fields of the corresponding elasticsearch document. The primaryKey for elasticsearch documents is the _id field by default which is not part of the attributes. You may define path mapping for the _id field so that it is part of the _source fields and thus becomes part of the attributes.

public string[] attributes ( )
return string[]

List of attribute names.
throws \yii\base\InvalidConfigException

if not overridden in a child class.

 

                public function attributes()
{
    throw new InvalidConfigException('The attributes() method of elasticsearch ActiveRecord has to be implemented by child classes.');
}
delete() public method

public integer|boolean delete ( array $options = [] )
$options array

Options given in this parameter are passed to elasticsearch as request URI parameters. These are among others:

  • routing define shard placement of this record.
  • parent by giving the primaryKey of another record this defines a parent-child relation
  • timeout timeout waiting for a shard to become available.
  • replication the replication type for the delete/index operation (sync or async).
  • consistency the write consistency of the index/delete operation.
  • refresh refresh the relevant primary and replica shards (not the whole index) immediately after the operation occurs, so that the updated document appears in search results immediately.

Please refer to the elasticsearch documentation for more details on these options.

The following parameters are Yii specific:

  • optimistic_locking set this to true to enable optimistic locking, avoid updating when the record has changed since it has been loaded from the database. Yii will set the version parameter to the value stored in version. See the elasticsearch documentation for details.

    Make sure the record has been fetched with a version before. This is only the case for records fetched via get() and mget() by default. For normal queries, the _version field has to be fetched explicitly.
return integer|boolean

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

if optimistic locking is enabled and the data being deleted is outdated.

        $model->afterFind();
        return $model;
    }
    return null;
}
getDb() public static method

Returns the database connection used by this AR class.

{
    return Inflector::pluralize(Inflector::camel2id(StringHelper::basename(get_called_class()), '-'));
}
insert() public method

Inserts a document into the associated index using the attribute values of this record.

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 database. 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 will be inserted into database.

If the primary key is not set (null) during insertion, it will be populated with a randomly generated value after insertion.

For example, to insert a customer record:

$customer = new Customer;
$customer->name = $name;
$customer->email = $email;
$customer->insert();
public boolean insert ( boolean $runValidation = true, array $attributes = null, array $options = ['op_type' => 'create'] )
$runValidation boolean

Whether to perform validation before saving the record. If the validation fails, the record will not be inserted into the database.
$attributes array

List of attributes that need to be saved. Defaults to null, meaning all attributes will be saved.
$options array

Options given in this parameter are passed to elasticsearch as request URI parameters. These are among others:

  • routing define shard placement of this record.
  • parent by giving the primaryKey of another record this defines a parent-child relation
  • timestamp specifies the timestamp to store along with the document. Default is indexing time.

Please refer to the elasticsearch documentation for more details on these options.

By default the op_type is set to create.
return boolean

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

 

                public function insert($runValidation = true, $attributes = null, $options = ['op_type' => 'create'])
{
    if ($runValidation && !$this->validate($attributes)) {
        return false;
    }
    if (!$this->beforeSave(true)) {
        return false;
    }
    $values = $this->getDirtyAttributes($attributes);
    $response = static::getDb()->createCommand()->insert(
        static::index(),
        static::type(),
        $values,
        $this->getPrimaryKey(),
        $options
    );
    
    if ($response === false) {
        return false;
    }
    $pk = static::primaryKey()[0];
    $this->$pk = $response['_id'];
    if ($pk != '_id') {
        $values[$pk] = $response['_id'];
    }
    $this->_version = $response['_version'];
    $this->_score = null;
    $changedAttributes = array_fill_keys(array_keys($values), null);
    $this->setOldAttributes($values);
    $this->afterSave(true, $changedAttributes);
    return true;
}
instantiate() public static method

Creates an active record instance.

This method is called together with populateRecord() by yii\elasticsearch\ActiveQuery. It is not meant to be used for creating new records directly.

You may override this method if the instance being created depends on the row data to be populated into the record. For example, by creating a record based on the value of a column, you may implement the so-called single-table inheritance mapping.

public static static instantiate ( array $row )
$row array

Row data to be populated into the record. This array consists of the following keys:

  • _source: refers to the attributes of the record.
  • _type: the type this record is stored in.
  • _index: the index this record is stored in.
return yii\elasticsearch\ActiveRecord

The newly created active record

 

                public static function instantiate($row)
{
    return new static;
}

$options array

Options given in this parameter are passed to elasticsearch as request URI parameters.

Please refer to the elasticsearch documentation for more details on these options.
return array

The record instances, or empty array if nothing was found

 

                public static function mget(array $primaryKeys, $options = [])
{
    if (empty($primaryKeys)) {
        return [];
    }
    if (count($primaryKeys) === 1) {
        $model = static::get(reset($primaryKeys));
        return $model === null ? [] : [$model];
    }
    $command = static::getDb()->createCommand();
    $result = $command->mget(static::index(), static::type(), $primaryKeys, $options);
    $models = [];
    foreach ($result['docs'] as $doc) {
        if ($doc['found']) {
            $model = static::instantiate($doc);
            static::populateRecord($model, $doc);
            $model->afterFind();
            $models[] = $model;
        }
    }
    return $models;
}
optimisticLock() public method

This method has no effect in Elasticsearch ActiveRecord.

Elasticsearch ActiveRecord uses native Optimistic locking. See update() for more details.

public mixed optimisticLock ( )

                public function optimisticLock()
{
    return null;
}
populateRecord() public static method

public static populateRecord ( yii\elasticsearch\ActiveRecord $record, array $row )
$record yii\elasticsearch\ActiveRecord

The record to be populated. In most cases this will be an instance created by instantiate() beforehand.

{
    $attributes = [];
    if (isset($row['_source'])) {
        $attributes = $row['_source'];
    }
    if (isset($row['fields'])) {
        // reset fields in case it is scalar value
        $arrayAttributes = $record->arrayAttributes();
        foreach ($row['fields'] as $key => $value) {
            if (!isset($arrayAttributes[$key]) && count($value) === 1) {
                $row['fields'][$key] = reset($value);
            }
        }
        $attributes = array_merge($attributes, $row['fields']);
    }
    parent::populateRecord($record, $attributes);
    $pk = static::primaryKey()[0];//TODO should always set ID in case of fields are not returned
    if ($pk === '_id') {
        $record->_id = $row['_id'];
    }
    $record->_highlight = isset($row['highlight']) ? $row['highlight'] : null;
    $record->_score = isset($row['_score']) ? $row['_score'] : null;
    $record->_version = isset($row['_version']) ? $row['_version'] : null; // TODO version should always be available...
    $record->_explanation = isset($row['_explanation']) ? $row['_explanation'] : null;
}
primaryKey() public static method

This method defines the attribute that uniquely identifies a record.

The primaryKey for elasticsearch documents is the _id field by default. This field is not part of the ActiveRecord attributes so you should never add _id to the list of attributes.

You may override this method to define the primary key name when you have defined path mapping for the _id field so that it is part of the _source and thus part of the attributes.

Note that elasticsearch only supports one attribute to be the primary key. However to match the signature of the \yii\db\ActiveRecordInterface this methods returns an array instead of a single string.

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

Array of primary key attributes. Only the first element of the array will be used.

 

                public static function primaryKey()
{
    return ['_id'];
}
primaryKeysByCondition() protected static method (available since version 2.0.4)

Performs a quick and highly efficient scroll/scan query to get the list of primary keys that satisfy the given condition. If condition is a list of primary keys (e.g.: ['_id' => ['1', '2', '3']]), the query is not performed for performance considerations.

See also:

protected static array primaryKeysByCondition ( array $condition )
$condition array

Please refer to ActiveQuery::where() on how to specify this parameter

    if (count($condition) == 1 && isset($condition[$pkName])) {
        $primaryKeys = (array)$condition[$pkName];
    } else {
        //fetch only document metadata (no fields), 1000 documents per shard
        $query = static::find()->where($condition)->asArray()->source(false)->limit(1000);
        $primaryKeys = [];
        foreach ($query->each('1m') as $document) {
            $primaryKeys[] = $document['_id'];
        }
    }
    return $primaryKeys;
}
setPrimaryKey() public method

                public function setPrimaryKey($value)
{
    $pk = static::primaryKey()[0];
    if ($this->getIsNewRecord() || $pk != '_id') {
