Accessor that decrypts model value isn't working - laravel

Question

I have a trait that uses accessors and mutators to encrypt model values:
trait Encryptable
{
public function getAttribute($key)
{
$value = parent::getAttribute($key);
if (in_array($key, $this->encryptable)) {
$value = Crypt::decrypt($value);
return $value;
} else {
return $value;
}
}
public function setAttribute($key, $value)
{
if (in_array($key, $this->encryptable)) {
$value = Crypt::encrypt($value);
}
return parent::setAttribute($key, $value);
}
}
Comments Model
protected $fillable = ['content','user_id','commentable_id', 'commentable_type'];
protected $encryptable = [
'content'
];
CommentController
public function storePostComment(Request $request, Post $Post)
{
$this->validate($request, [
'content' => 'required',
]);
$comment = $post->comments()->create([
'user_id' => auth()->user()->id,
'content' => $request->content
]);
dd($comment->content);
//return new CommentResource($comment);
}
What's happening is that when I pass the return new CommentResource($comment); gives me the comments content encrypted, but dd($comment->content); decrypts the comments content. How do I decrypt the entire comment object so I can output it in a resource?
Edit For CommentResource
class CommentResource extends JsonResource
{
/**
* Transform the resource into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
return [
'id' => $this->id,
'content' => $this->content,
'owner' => $this->owner,
];
}
}
Edit 2 for answer
Here's my attempt:
use App\Comment;
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class CommentResource extends JsonResource
{
public function __construct(Comment $resource)
{
$this->resource = $resource;
}
/**
* Transform the resource into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
return [
'id' => $this->id,
'content' => $this->content,
'owner' => $this->owner,
];
}
}
Error:
Argument 1 passed to App\Http\Resources\CommentResource::__construct() must be an instance of App\Http\Resources\Comment, instance of App\Comment given, called in /Applications/MAMP/htdocs/my-app/app/Http/Controllers/Api/CommentController.php on line 31
Edit 3 (final edit)
Here's what I figured out:
I tried a bunch of various combinations along with #Edwin Krause answer. I have another model using this encryptable trait and outputting in a resource that works fine.
To give a bit more context to this question I found out there was a problem using assertJsonFragment in a test:
CommentsTest
/* #test **/
public function a_user_can_comment_on_a_post()
{
$decryptedComment = ['content'=>'A new content']
$response = $this->json('POST', '/api/comment/' . $post->id, $decryptedComment);
$response->assertStatus(201);
$response->assertJsonStructure([
'data' => [
'owner',
'content'
]
])
->assertJsonFragment(['content' => $decryptedContent['content']]);
}
assertJsonFragment was returning the encrypted content and therefore failing because it was being tested against the decrypted comments content.
I used dd(new CommentResource($comment)); in the controller to check to see if it the content was decrypting, it wasn't.
I tried various different things trouble shooting with dd() in the controller method and even testing in the browser. Still nothing. I added #Edwin Krause code and still nothing on dd()
I finally got lucky and got rid of dd() with #Edwin Krause and changing my controller to:
Working code combined with #Edwin Krause answer in my CommentResource
$comment = Comment::create([
'user_id' => auth()->user()->id,
'content' => $request->content,
'commentable_type' => 'App\Post',
'commentable_id' => $post->id,
]);
return new CommentResource($comment);
The tests went green. I tried dd(new CommentResource($comment)); and the content was encrypted still. The content output on the broweser and assertJsonFragment worked. I must've tried so many combinations to try and figure this out and I kind of just got lucky.
I'm unsure as to why this is the way it is, but I've already spent hours on this, so I can't troubleshoot why it's breaking. Maybe someone else can.

Answer 1

Just a suggestion to try and override the constructor of the JsonResource and typecast the $resource parameter to your Modelclass.
It work's for other things, not sure if it fixes your issue, that needs to be tested
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
use App\Comment;
class CommentResource extends JsonResource
{
public function __construct(Comment $resource)
{
$this->resource = $resource;
$this->resource->content = $resource->content;
}
....
Edit:
I Played around a bit more with the constructor and the modified version should actually work. I don't have any encrypted data to play with, but logically this should work.
