ActiveQuery represents a Sphinx query associated with an Active Record class.
An ActiveQuery can be a normal query or be used in a relational context.
ActiveQuery instances are usually created by yii\sphinx\ActiveRecord::find() and yii\sphinx\ActiveRecord::findBySql(). Relational queries are created by yii\sphinx\ActiveRecord::hasOne() and yii\sphinx\ActiveRecord::hasMany().
Normal Query ¶
Because ActiveQuery extends from yii\sphinx\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:
$articles = Article::find()->with('source')->asArray()->all();
ActiveQuery allows to build the snippets using sources provided by ActiveRecord. You can use snippetByModel() method to enable this. For example:
class Article extends ActiveRecord
{
public function getSource()
{
return $this->hasOne('db', ArticleDb::className(), ['id' => 'id']);
}
public function getSnippetSource()
{
return $this->source->content;
}
...
}
$articles = Article::find()->with('source')->snippetByModel()->all();
Relational query ¶
In relational context ActiveQuery represents a relation between two Active Record classes.
Relational ActiveQuery instances are usually created by calling yii\sphinx\ActiveRecord::hasOne() and yii\sphinx\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.
