Override the route binding resolver for each of your models

You can override the route binding resolver for each of your models. In this example, I have no control over the @ sign in the URL, so using the resolveRouteBinding method, I'm able to remove the @ sign and resolve the model.

 1// Route
 2Route::get('{product:slug}', Controller::class);
 3 
 4// Request
 5https://nodejs.pub/@unlock/hello-world
 6 
 7// Product Model
 8public function resolveRouteBinding($value, $field = null)
 9{
10    $value = str_replace('@', '', $value);
11 
12    return parent::resolveRouteBinding($value, $field);
13}
