FAL resource not accessible in fluid template - where to look?

Question

In a custom extbase extension, we have an image field set up like this:

Model

/**
 * Returns the picture
 *
 * @return \TYPO3\CMS\Extbase\Domain\Model\FileReference $picture
 */
public function getPicture()
{
    return $this->picture;
}

/**
 * Sets the picture
 *
 * @param \TYPO3\CMS\Extbase\Domain\Model\FileReference $picture
 * @return void
 */
public function setPicture(\TYPO3\CMS\Extbase\Domain\Model\FileReference $picture)
{
    $this->picture = $picture;
}

        'exclude' => 0,

When I try to access the FAL resource in fluid via

<f:image src="{myextitem.picture}" width="600" height="750c"/>

an empty image tag is output.

I can access the original resource with

<f:image src="{myextitem.picture.originalResource.publicUrl}" width="600" height="750c"/>

but that doesn't respect modifications to the image by the crop wizard.

Where shoud I look to make the FAL resource accessible by fluid?

Answer 1

Have a look in the ImageViewHelpers render() method. The accepted parameter are explained there:

* @param string $src a path to a file, a combined FAL identifier or an uid (int). If $treatIdAsReference is set, the integer is considered the uid of the sys_file_reference record. If you already got a FAL object, consider using the $image parameter instead
* ...
* @param FileInterface|AbstractFileFolder $image a FAL object

So if you use src="{imageResource}" it won't work because src expects a string.

Try <f:image image="{imageResource}" width="600" height="750c"/> instead.
