Save logged in user's id to database when I have $request->all()

Question

I want to save new post from form in my database, I have title and body in $request and want to save logged in user's id in the post. how can i handle it in model or validation?

    Validator::make($request->all(), [
        'title' => ['required'],
        'body' => ['required'],
    ])->validate();
    Post::create($request->all());

I can save it as below:

$post = new Flight;
$post->title = $request->title;
$post->body = $request->body;
$post->user_id = $request->user()->id;
$post->save();

but I want better way.

• user_id is not nullable in DB

Answer 1

Here's a sample code that I always use.

use Illuminate\Http\JsonResponse;
use Illuminate\Http\Response;    
...

public function store(Request $request)
{
   // take only fields that have been validated.
   // instead of inserting all the request body
   $validated = $request->validate([
      'title' => 'required',
      'body' => 'required'
   ]);

   // use FormRequest if want seperate validation and its much cleaner
   // something like this
   // store(StorePostRequest $request)
   //   $validated = $request->validated();

   // instead of declaring use Auth
   // u can just use $request->user();
   $post = $request->user()->post()->create($validated);

   // or if you dont have the relation inside the user model
   $post = Post::create(['user_id' => auth()->id()] + $validated);

   return new JsonResponse($post, Response::HTTP_CREATED);
}

Include Authentication Facade in Controller header use Auth; than you can use $post->user_id = Auth::id();

you can use both Auth::user()->id or Auth::id() . Thanks

You can use form request validation to extract validation login from the controller (seedocumentation ).

I'd suggest to use $request->validated() method instead of $request->all() to make sure that only expected fields are passed to the model.

Also, you can use a auth()->id() helper method to get logged in user's ID.

So, the controller function could be as follows:

Post::create(array_merge($request->validated(), ['user_id' => auth()->id()]));
