Laravel 5.6 - Pass additional parameters to API Resource?

Question

A Laravel API Resource can be either a single resource or a collection. In some cases, additional parameters are required to be passed to the resource/collection from the co

Answer 1

You can pass the extra parameters in as part of the call to the API endpoint. You can then access the parameters with the $request object (for your example) in the UserResource.

For example, if you call the endpoint from a client such a web browser, axios, etc. using something like:

http://localhost:3000/api/users?apple=true

this will make the parameter apple with a value of true available in the controller. Without any other action on your part it will then also be accessible in the toArray($request) of the UserResource. You can access it similar to:

public function toArray($request) {
      $isApple = $request->apple;

        return [
            'id'     => (int) $this->id, 
            'name'   => $this->name,
            'fruit'  => $isApple ? 'apple' : 'banana',
        ];
    }

Answer 2

To works with Laravel 5.7, I made some changes in relation to Wonka's answer

UserResource

    class UserResource extends Resource{

        protected $foo;

        public function foo($value){
            $this->foo = $value;
            return $this;
        }

        public function toArray($request){
            return [
                'id' => $this->id,
                'name' => $this->name,
                'foo' => $this->foo,
             ];
        }

        public static function collection($resource){
            return new UserResourceCollection($resource, get_called_class());
        }
    }

UserCollection

    class UserResourceCollection extends AnonymousResourceCollection {

        protected $foo;

        public function foo($value){
            $this->foo = $value;
            return $this;
        }

        public function toArray($request){
            return $this->collection->map(function(UserResource $resource) use($request){
                return $resource->foo($this->foo)->toArray($request);
        })->all();

        }
    }

Answer 3

I solved my issue, by just retrieving the $request->get('param') inside the

public function toArray($request){ 

   $param = $request->get('param');

   ... 

} 

Instead of passing the param through the Resource.

Answer 4

The following approach worked for me:

UserResource

class UserResource extends Resource{

    protected $foo;

    public function foo($value){
        $this->foo = $value;
        return $this;
    }

    public function toArray($request){
        return [
            'id' => $this->id,
            'name' => $this->name,
            'foo' => $this->foo,
         ];
    }

    public static function collection($resource){
        return new UserResourceCollection($resource);
    }
}

UserCollection

class UserResourceCollection extends ResourceCollection{

    protected $foo;

    public function foo($value){
        $this->foo = $value;
        return $this;
    }

    public function toArray($request){
        return $this->collection->map(function(UserResource $resource) use($request){
            return $resource->foo($this->foo)->toArray($request);
    })->all();

        // or use HigherOrderCollectionProxy
        // return $this->collection->each->foo($this->foo)->map->toArray($request)->all()

        // or simple
        // $this->collection->each->foo($this->foo);
        // return parent::toArray($request);
    }
}

Different ways to pass the additional parameter

(new UserResource($user))->foo('bar');
(new UserResourceCollection($user))->foo('bar');

UserResource::make($user)->foo('bar');
UserResourceCollection::make($users)->foo('bar');
UserResource::collection($users)->foo('bar');

Answer 5

You can use laravel 8

for store function Additional

    return (UserResource::make(User::find($user->id)))
            ->additional([
                'message'=>[
                    ['user by name: '.$user->name.' created successfull.']
                ]
            ])->response()->setStatusCode(201);

Answer 6

This simple trick worked for me in Laravel 5.8 :)

Controller

$user = User::find($user->id);
$user->access_token = $tokenResult->accessToken; // Add additional data
return new ProfileResource($user);

Resource

public function toArray($request)
{
    return [
        'id'            => $this->id,
        'picture'       => $this->picture,
        'first_name'    => $this->first_name,
        'last_name'     => $this->last_name,
        'active'        => $this->active,
        'access_token'  => isset($this->access_token) ? $this->access_token : '', // Additional data
    ];
}
