     * Request primary selector loader to pre-load relation name. Any type of loader can be used

     * related data which might include additional select query or left join. Loaded data will
     * automatically pre-populate record relations. You can specify nested relations using "."
     * separator.
     *
     * Examples:
     *
     * // Select users and load their comments (will cast 2 queries, HAS_MANY comments)
     * User::find()->with('comments');
     *
     * // You can load chain of relations - select user and load their comments and post related to

     * // comments.
     * User::find()->load('comments', [
     *      'where' => ['{@}.status' => 'public']
     * ]);
     *
     * Please note using "{@}" column name, this placeholder is required to prevent collisions and
     * it will be automatically replaced with valid table alias of pre-loaded comments table.
     *
     * // In case where your loaded relation is MANY_TO_MANY you can also specify pivot table
     * // conditions, let's pre-load all approved user tags, we can use same placeholder for pivot
     * // table alias
     * User::find()->load('tags', [
     *      'wherePivot' => ['{@}.approved' => true]
     * ]);
     *
     * // In most of cases you don't need to worry about how data was loaded, using external query
     * // or left join, however if you want to change such behaviour you can force load method to
     * // INLOAD
     * User::find()->load('tags', [
     *      'method'     => Loader::INLOAD,
     *      'wherePivot' => ['{@}.approved' => true]
     * ]);
     *
     * Attention, you will not be able to correctly paginate in this case and only ORM loaders
     * support different loading types.
     *
     * You can specify multiple loaders using array as first argument.
     *
     * Example:
     * User::find()->load(['posts', 'comments', 'profile']);
     *
     * Attention, consider disabling entity map if you want to use recursive loading (i.e
     * post.tags.posts), but first think why you even need recursive relation loading.

     *
     * Method generally used to filter data based on some relation condition. Attention, with()
     * method WILL NOT load relation data, it will only make it accessible in query.
     *
     * By default joined tables will be available in query based on relation name, you can change
     * joined table alias using relation option "alias".
     *
     * Do not forget to set DISTINCT flag while including HAS_MANY and MANY_TO_MANY relations. In
     * other scenario you will not able to paginate data well.

     *
     * // Find all users who have comments comments

     *
     * // Find all users who have posts which have approved comments
     * User::find()->with('posts.comments')->where('posts_comments.approved', true);
     *
     * // Custom join alias for post comments relation
     * $user->with('posts.comments', [
     *      'as' => 'comments'
     * ])->where('comments.approved', true);
     *
     * // If you joining MANY_TO_MANY relation you will be able to use pivot table used as relation
     * // name plus "_pivot" postfix. Let's load all users with approved tags.
     * $user->with('tags')->where('tags_pivot.approved', true);
     *
     * // You can also use custom alias for pivot table as well
     * User::find()->with('tags', [
     *      'pivotAlias' => 'tags_connection'
     * ])
     * ->where('tags_connection.approved', false);
     *
     * You can safely combine with() and load() methods.
     *
     * // Load all users with approved comments and pre-load all their comments
     * User::find()->with('comments')->where('comments.approved', true)->load('comments');

208			* Request primary selector loader to pre-load relation name. Any type of loader can be used
209			* for data pre-loading. ORM loaders by default will select the most efficient way to load
210			* related data which might include additional select query or left join. Loaded data will
211			* automatically pre-populate record relations. You can specify nested relations using "."
212			* separator.
213			*
214			* Examples:
215			*
216			* // Select users and load their comments (will cast 2 queries, HAS_MANY comments)
217			* User::find()->with('comments');
218			*
219			* // You can load chain of relations - select user and load their comments and post related to
220			* //comment
221			* User::find()->with('comments.post');
222			*
223			* // We can also specify custom where conditions on data loading, let's load only public
224			* // comments.
225			* User::find()->load('comments', [
226			* 'where' => ['{@}.status' => 'public']
227			* ]);
228			*
229			* Please note using "{@}" column name, this placeholder is required to prevent collisions and
230			* it will be automatically replaced with valid table alias of pre-loaded comments table.
231			*
232			* // In case where your loaded relation is MANY_TO_MANY you can also specify pivot table
233			* // conditions, let's pre-load all approved user tags, we can use same placeholder for pivot
234			* // table alias
235			* User::find()->load('tags', [
236			* 'wherePivot' => ['{@}.approved' => true]
237			* ]);
238			*
239			* // In most of cases you don't need to worry about how data was loaded, using external query
240			* // or left join, however if you want to change such behaviour you can force load method to
241			* // INLOAD
242			* User::find()->load('tags', [
243			* 'method' => Loader::INLOAD,
244			* 'wherePivot' => ['{@}.approved' => true]
245			* ]);
246			*
247			* Attention, you will not be able to correctly paginate in this case and only ORM loaders
248			* support different loading types.
249			*
250			* You can specify multiple loaders using array as first argument.
251			*
252			* Example:
253			* User::find()->load(['posts', 'comments', 'profile']);
254			*
255			* Attention, consider disabling entity map if you want to use recursive loading (i.e
256			* post.tags.posts), but first think why you even need recursive relation loading.

288			*
289			* Method generally used to filter data based on some relation condition. Attention, with()
290			* method WILL NOT load relation data, it will only make it accessible in query.
291			*
292			* By default joined tables will be available in query based on relation name, you can change
293			* joined table alias using relation option "alias".
294			*
295			* Do not forget to set DISTINCT flag while including HAS_MANY and MANY_TO_MANY relations. In
296			* other scenario you will not able to paginate data well.

299			*

305			*
306			* // Find all users who have posts which have approved comments
307			* User::find()->with('posts.comments')->where('posts_comments.approved', true);

315			* // name plus "_pivot" postfix. Let's load all users with approved tags.
316			* $user->with('tags')->where('tags_pivot.approved', true);
317			*
318			* // You can also use custom alias for pivot table as well
