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.

// Route
Route::get('{product:slug}', Controller::class);
 
// Request
https://nodejs.pub/@unlock/hello-world
 
// Product Model
public function resolveRouteBinding($value, $field = null)
{
    $value = str_replace('@', '', $value);
 
    return parent::resolveRouteBinding($value, $field);
}
