[TYPO3-mvc] How to get first object of an 1:n relation

[Claus Due]

Hi Dmitri,

ObjectStorage can be converted to array but cannot be accessed with numeric indexes like an array can. That's the reason why the .0 trick doesn't work on ObjectStorage.

You can do this though:

$images = $place->getImages()->toArray();
$this->view->assign('images', $images);

and then {images.0.filename} or whatever.

If you are looping {places} in Fluid then your only option is a ViewHelper which can read the first item off of an ObjectStorage and re-assign as a template variable (or simply return, if you only use it inline).
