Responda
-
This can be achieved in a TypoScript file.
-
By passing the parameter $order in the method’s signature

By adding an appropriate sortby property to the TCA
Questão 9
Questão
Which statements about the following code snippet are correct? (2)
<?php
namespace Vendor\MyExtension\Domain\Repository;
use \TYPO3\CMS\Extbase\Persistence\Repository;

class ExampleRepository extends Repository
{
protected $defaultOrderings = [
'title' => QueryInterface::ORDER_DESCENDING
];
...
}
Responda
-
Records read from this repository are sorted by their title field in descending order by default
-
The additional configuration sortBy is required in the TCA of the repository to set the default sort order
-
The property $defaultOrderings has no effect by default
-
The constant ORDER_ASCENDING can be used instead of ORDER_DESCENDING to sort in ascending order
-
If the property $defaultOrderings would not exist, the repository would use the sorting defined in the TCA

Responda
-
By searching in the Book repository and by using in() on the property chapters
-
By searching in the Book repository and by using contains() on the property chapters

-
By searching in the Chapters repository and by using contains() on the property books
-
By searching in the Chapters repository and iterating all records to find the appropriate chapters
