eagerLoadingMap()

Returns an array that maps source-to-target element IDs based on the given sub-property handle.

This method aids in the eager-loading of elements when performing an element query. The returned array should contain the following keys:

• elementType – the fully qualified class name of the element type that should be eager-loaded
• map – an array of element ID mappings, where each element is a sub-array with source and target keys.
• criteria (optional) – Any criteria parameters that should be applied to the element query when fetching the eager-loaded elements.

use craft\db\Query;
use craft\helpers\ArrayHelper;

public static function eagerLoadingMap(array $sourceElements, string $handle) {
    switch ($handle) {
        case 'author':
            $bookIds = ArrayHelper::getColumn($sourceElements, 'id');
            $map = (new Query)
                ->select(['source' => 'id', 'target' => 'authorId'])
                ->from('{{%books}}')
                ->where(['id' => $bookIds)
                ->all();
            return [
                'elementType' => \my\plugin\Author::class,
                'map' => $map,
            ];
        case 'bookClubs':
            $bookIds = ArrayHelper::getColumn($sourceElements, 'id');
            $map = (new Query)
                ->select(['source' => 'bookId', 'target' => 'clubId'])
                ->from('{{%bookclub_books}}')
                ->where(['bookId' => $bookIds)
                ->all();
            return [
                'elementType' => \my\plugin\BookClub::class,
                'map' => $map,
            ];
        default:
            return parent::eagerLoadMap($sourceElements, $handle);
    }
}

View source

Arguments

• $sourceElements (craft\base\ElementInterface[]) – An array of the source elements
• $handle (string) – The property handle used to identify which target elements should be included in the map

Returns

array, false, null – The eager-loading element ID mappings, false if no mappings exist, or null if the result should be ignored

extraFields()

Returns the list of fields that can be expanded further and returned by toArray().

This method is similar to fields() except that the list of fields returned by this method are not returned by default by toArray(). Only when field names to be expanded are explicitly specified when calling toArray(), will their values be exported.

The default implementation returns an empty array.

You may override this method to return a list of expandable fields based on some context information (e.g. the current application user).

View source

Returns

array – The list of expandable field names or field definitions. Please refer to fields() on the format of the return value.

find()

Creates an craft\elements\db\ElementQueryInterface instance for query purpose.

The returned craft\elements\db\ElementQueryInterface instance can be further customized by calling methods defined in craft\elements\db\ElementQueryInterface before one() or all() is called to return populated craft\base\ElementInterface instances. For example,

// Find the entry whose ID is 5
$entry = Entry::find()->id(5)->one();
// Find all assets and order them by their filename:
$assets = Asset::find()
    ->orderBy('filename')
    ->all();

If you want to define custom criteria parameters for your elements, you can do so by overriding this method and returning a custom query class. For example,

class Product extends Element
{
    public static function find()
    {
        // use ProductQuery instead of the default ElementQuery
        return new ProductQuery(get_called_class());
    }
}

You can also set default criteria parameters on the ElementQuery if you don’t have a need for a custom query class. For example,

class Customer extends ActiveRecord
{
    public static function find()
    {
        return parent::find()->limit(50);
    }
}

View source

Returns

craft\elements\db\MatrixBlockQuery – The newly created craft\elements\db\MatrixBlockQuery instance.
