Access model binding in FormRequests

When using FormRequests, you can always access the binding model by simply using the following expression $𝘁𝗵𝗶𝘀->{𝗿𝗼𝘂𝘁𝗲-𝗯𝗶𝗻𝗱𝗶𝗻𝗴-𝘃𝗮𝗿𝗶𝗮𝗯𝗹𝗲}

Here's an example.

class CommunityController extends Controller
{
     // ...
     public function update(CommunityUpdateRequest $request, Community $community)
     {
          $community->update($request->validated());
 
          return to_route('communities.index')->withMessage('Community updated successfully.');
     }
     // ...
}
 
class CommunityUpdateRequest extends FormRequest
{
     // ...
     public function rules()
     {
          return [
               'name' => ['required', Rule::unique('communities', 'name')->ignore($this->community)],
               'description' => ['required', 'min:5'],
          ];
     }
     // ...
}
