Additional data in Laravel Resource - laravel

Question

I use Laravel resource from the controller:
$data = Project::limit(100)->get();
return response()->json(ProjectResource::collection($data));
I like to pass additional information to the ProjectResource. How it's possible? And how can i access the additional data?
I tried like this:
$data = Project::limit(100)->get();
return response()->json(ProjectResource::collection($data)->additional(['some_id => 1']);
But it's not working.
What's the right way?
I like to access the some_id in the resource like this.
public function toArray($request)
{
return [
'user_id' => $this->id,
'full_name' => $this->full_name,
'project_id' => $this->additional->some_id
];
}

In your controller don't wrap return Resource in response()->json.
Just return ProjectResource.
So like:
$data = Project::limit(100)->get();
return ProjectResource::collection($data)->additional(['some_id => 1']);
Sorry for misunderstanding the question.
I don't think there is an option to pass additional data like this. So you will have to loop over the collection and add this somehow.
One option is to add to resources in AnonymousCollection. For example:
$projectResource = ProjectResource::collection($data);
$projectResource->map(function($i) { $i->some_id = 1; });
return $projectResource;
and then in ProjectResource:
return [
'user_id' => $this->id,
'full_name' => $this->full_name,
'project_id' => $this->when( property_exists($this,'some_id'), function() { return $this->some_id; } ),
];
Or add some_id to project collection befour passing it to ResourceCollection.
