Member Data Documentation

◆ $configuration

array TYPO3\CMS\Extbase\Mvc\View\JsonView::$configuration = array( )

The rendering configuration for this JSON view which determines which properties of each variable to render.

The configuration array must have the following structure:

Example 1:

[ 'variable1' => [ '_only' => ['property1', 'property2', ...] ], 'variable2' => [ '_exclude' => ['property3', 'property4, ...] ], 'variable3' => [ '_exclude' => ['secretTitle'], '_descend' => [ 'customer' => [ '_only' => ['firstName', 'lastName'] ] ] ], 'somearrayvalue' => [ '_descendAll' => [ '_only' => ['property1'] ] ] ]

Of variable1 only property1 and property2 will be included. Of variable2 all properties except property3 and property4 are used. Of variable3 all properties except secretTitle are included.

If a property value is an array or object, it is not included by default. If, however, such a property is listed in a "_descend" section, the renderer will descend into this sub structure and include all its properties (of the next level).

The configuration of each property in "_descend" has the same syntax like at the top level. Therefore - theoretically - infinitely nested structures can be configured.

To export indexed arrays the "_descendAll" section can be used to include all array keys for the output. The configuration inside a "_descendAll" will be applied to each array element.

Example 2: exposing object identifier

[ 'variableFoo' => [ '_exclude' => ['secretTitle'], '_descend' => [ 'customer' => [ // consider 'customer' being a persisted entity '_only' => ['firstName'], '_exposeObjectIdentifier' => TRUE, '_exposedObjectIdentifierKey' => 'guid' ] ] ] ]

Note for entity objects you are able to expose the object's identifier also, just add an "_exposeObjectIdentifier" directive set to TRUE and an additional property '__identity' will appear keeping the persistence identifier. Renaming that property name instead of '__identity' is also possible with the directive "_exposedObjectIdentifierKey". Example 2 above would output (summarized): {"customer":{"firstName":"John","guid":"892693e4-b570-46fe-af71-1ad32918fb64"}}

Example 3: exposing object's class name

[ 'variableFoo' => [ '_exclude' => ['secretTitle'], '_descend' => [ 'customer' => [ // consider 'customer' being an object '_only' => ['firstName'], '_exposeClassName' => \TYPO3\CMS\Extbase\Mvc\View\JsonView::EXPOSE_CLASSNAME_FULLY_QUALIFIED ] ] ] ]

The _exposeClassName is similar to the objectIdentifier one, but the class name is added to the JSON object output, for example (summarized): {"customer":{"firstName":"John","__class":"Acme\Foo\Domain\Model\Customer"}}

The other option is EXPOSE_CLASSNAME_UNQUALIFIED which only will give the last part of the class without the namespace, for example (summarized): {"customer":{"firstName":"John","__class":"Customer"}} This might be of interest to not provide information about the package or domain structure behind.

Definition for the class name exposure configuration, that is, if the class name of an object should also be part of the output JSON, if configured.

Setting this value, the object's class name is fully put out, including the namespace.

Puts out only the actual class name without namespace. See EXPOSE_CLASSNAME_FULL for the meaning of the constant at all.
