Hi there!
I’m creating many pages from a CSV file. The CLI is an awesome tool and coupled with this library I’ve managed to import almost all fields easily.
Though, I’m stuck on a file field. I need to add an image for each page. All images are in a folder and there’s one column in the CSV where the image filename is specified.
I’m not sure where to start from. 
Couldn’t find any example in that spirit for K4.
What exactly is the missing piece here? Moving the image to the correct location, or how to store the filename in a files field (needs to be stored as array of filenames, as the files field stores its data in yaml format)
Thanks for your answer @texnixe
I realize what I was looking for was already packaged in File::create and with a nice example. 
It’s almost all good, here’s where I am :
$i=0;
foreach ($csv as $offset => $ref) {
if($i==0) {
$reference = $references->createChild([
'slug' => Str::slug($ref['TITRE'],"-"),
'draft' => true,
'template' => 'reference',
'content' => [
'title' => $ref['TITRE'],
'refWho' => $ref['RÉALISATION'],
'refWhen' => setRefWhen($ref['ANNÉE']),
'refFormat' => setFormat($ref['FORMAT']),
'refLink' => setLink([$ref['LIEN IMDB'],$ref['LIEN UNIFRANCE'],$ref['LIEN ALLOCINE'],$ref['LIEN CREW UNITED']]),
'customer' => setCustomers($ref['PRODUCTION']),
'travaux' => setMissions($ref,$travaux),
'num' => 0,
],
]);
$artwork = File::create([
'source' => '../filmographie/affiches/'.$ref['VISUEL'].'.jpg',
'parent' => $reference,
'filename' => 'new-image.jpg',
'template' => 'artwork',
]);
$reference = $reference->update([
'artwork' => [$artwork->uuid()],
]);
try {
$reference = $reference->changeStatus('listed');
} catch (Exception $e) {
print($e);
}
}
$i++;
}
The only thing is I get an error when trying to list the page. Though, it’s all looking good in the panel, I can see the draft with all the right information and the page showing well.

I get this error :

I still can rename it in the finder and publish them all so it’s alright.
Alright, I found the issue. I had a ‘max’ on a certain field and my import was reaching over that max so Kirby was avoiding listing. 
I understood when I saw the error in the panel.
