ActiveQuery represents a yii\elasticsearch\Query associated with an yii\elasticsearch\ActiveRecord class.

An ActiveQuery can be a normal query or be used in a relational context.

ActiveQuery instances are usually created by yii\elasticsearch\ActiveRecord::find(). Relational queries are created by yii\elasticsearch\ActiveRecord::hasOne() and yii\elasticsearch\ActiveRecord::hasMany().

Normal Query

ActiveQuery mainly provides the following methods to retrieve the query results:

  • one(): returns a single record populated with the first row of data.
  • all(): returns all records based on the query results.
  • count(): returns the number of records.
  • scalar(): returns the value of the first column in the first row of the query result.
  • column(): returns the value of the first column in the query result.
  • exists(): returns a value indicating whether the query result has data or not.

Because ActiveQuery extends from yii\elasticsearch\Query, one can use query methods, such as where(), orderBy() to customize the query options.

ActiveQuery also provides the following additional query options:

  • with(): list of relations that this query should be performed with.
  • indexBy(): the name of the column by which the query result should be indexed.
  • asArray(): whether to return each record as an array.

These options can be configured using methods of the same name. For example:

$customers = Customer::find()->with('orders')->asArray()->all();

Note: elasticsearch limits the number of records returned to 10 records by default. If you expect to get more records you should specify limit explicitly.

Relational query

In relational context ActiveQuery represents a relation between two Active Record classes.

Relational ActiveQuery instances are usually created by calling yii\elasticsearch\ActiveRecord::hasOne() and yii\elasticsearch\ActiveRecord::hasMany(). An Active Record class declares a relation by defining a getter method which calls one of the above methods and returns the created ActiveQuery object.

A relation is specified by $link which represents the association between columns of different tables; and the multiplicity of the relation is indicated by $multiple.

If a relation involves a junction table, it may be specified by via(). This methods may only be called in a relational context. Same is true for inverseOf(), which marks a relation as inverse of another relation.

Note: elasticsearch limits the number of records returned by any query to 10 records by default. If you expect to get more records you should specify limit explicitly in relation definition. This is also important for relations that use via() so that if via records are limited to 10 the relations records can also not be more than 10.

Note: Currently with() is not supported in combination with asArray().
