API Platform

Question 1

Data Providers

Answer 1

To retrieve data exposed by the API, API Platform uses classes called data providers. A data provider using Doctrine ORM to retrieve data from a database, a data provider using Doctrine MongoDB ODM to retrieve data from a document database, and a data provider using Elasticsearch-PHP to retrieve data from an Elasticsearch cluster are included with the library. The first one is enabled by default. These data providers natively support paged collections and filters.

Question 2

Data Providers - two kinds of interface

Answer 2

For a given resource, you can implement two kinds of interface:

• the CollectionDataProviderInterface is used when fetching a collection.
• the ItemDataProviderInterface is used when fetching items.

Both implementations can also implement a third, optional, interface called ‘RestrictedDataProviderInterface’ if you want to limit their effects to a single resource or operation.

then yok them tov prer in controller’s construct to invoke method. Example:
public function __invoke($id, $invoiceNumber) {
return $this->contractInvoiceDataProvider->getItem(AccountsReceivableInvoice::class, [$id, $invoiceNumber], ‘GET’, [‘accounts_receivable_invoice_attachment_read’]);
}

Question 5

Extensions

Answer 5

API Platform Core provides a system to extend queries on items and collections.

Question 6

Custom Doctrine ORM Extension

Answer 6

Custom extensions must implement the ApiPlatform\Core\Bridge\Doctrine\Orm\Extension\QueryCollectionExtensionInterface and / or the ApiPlatform\Core\Bridge\Doctrine\Orm\Extension\QueryItemExtensionInterface interfaces, to be run when querying for a collection of items and when querying for an item respectively. If you use custom data providers, they must support extensions and be aware of active extensions to work properly.
