Is there any easy way of retrieving the route binded model within a Request?
I want to update a model, but before I do, I want to perform some permissions checks using the Requests authorize()
method. But I only want the owner of the model to be able to update it.
In the controller, I would simply do something like this:
public function update(Request $request, Booking $booking)
{
if($booking->owner->user_id === Auth::user()->user_id)
{
// Continue to update
}
}
But I’m looking to do this within the Request, rather than within the controller. If I do:
dd(Illuminate\Http\Request::all());
It only gives me the scalar form properties (such as _method
and so on, but not the model).
Question
If I bind a model to a route, how can I retrieve that model from within a Request?
Many thanks in advance.
Absolutely! It’s an approach I even use myself.
You can get the current route in the request, and then any parameters, like so:
class UpdateRequest extends Request
{
public function authorize()
{
$booking = $this->route('booking');
return $booking->owner->user_id == $this->user()->getKey();
}
}
Unlike smartman’s (now deleted) answer, this doesn’t incur another find query if you have already retrieved the model via route–model binding.
Answer:
Once you did your explicit binding (https://laravel.com/docs/5.5/routing#route-model-binding) you actually can get your model directly with $this.
class UpdateRequest extends Request
{
public function authorize()
{
return $this->booking->owner->user_id == $this->booking->user()->id;
}
}
Even cleaner!
Answer:
To add on to Martin Bean‘s answer, you can access the bound instance using just route($param)
:
class UpdateRequest extends Request { public function authorize() { $booking = $this->route('booking'); return $booking->owner->user_id == $this->user()->id; } }
Note: This works in Laravel 5.1. I have not tested this on older versions.
