Laravel - 如何检查数据是否存在？

Question

How to check if data exist, if it not exist then redirect to different page.

It keep saying data is exist even it does not exist.

In the model file, I have:

public static function getPackage($id)
{
    return Packages::where('id', '=', $id);
}

In the controller:

protected function checkPackage($id) 
{
    if (!Packages::getPackage($id)->get()) {
        Redirect::to('/')
    } 
}

{
$something = Packages::where('id', '=', $id)->get();

}

protected function checkPackage($id) 
{
$variable = getPackage();
if (!$variable ) 
{
    Redirect::to('/')
}
