/**
|
|
* ActiveQuery represents a Mongo query associated with an Active Record class.
|
|
*
|
|
* ActiveQuery instances are usually created by [[ActiveRecord::find()]].
|
|
*
|
|
* Because ActiveQuery extends from [[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.
|
|
* - [[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();
|
|
* ~~~
|
|
*
|
|
* @property Collection $collection Collection instance. This property is read-only.
