 public function boot()
    {
   		//don't forget import model at the top
        Route::model('unique_key', Blog::class);
        Route::bind('unique_key', function ($value) {
            return Blog::findOrFail($value);
           //return Blog::where('something', $value)->firstOrFail();
        });
   
   //default laravel codes
 }

Example 2: laravel route model binding

/**

public function resolveRouteBinding($value, $field = null)
