Laravel 5.7 authentication without login error: Property [id] does not exist on this collection instance












0














I'm trying to force an authentication without login with Laravel 5.7 like that:



public function login()
{

$cpf = Request::only('cpf');
$user = new User;
$user = $user->where('cpf', $cpf)->get();
Auth::loginUsingId($user->id);
return redirect('/perfil');

}


And I get this error: Property [id] does not exist on this collection instance.



When I debug the model User, all the attributes are there. But when I try to get the attributes, I get this error. What I'm doing wrong?



If there's any other way to authenticate without password, It would be helpful!

  • Typically one would say $user = User::where('cpf', $cpf)->get(); rather than instantiating a new object first. Regardless, what does dd($user) say? More importantly, what does dd($cpf) say? Is it a string?

If cpf is a unique column, then the following will return the object you're looking for:



$user = User::where('cpf', $cpf)->first();


If you do ->get() as in your code, you'll get a Collection with exactly one object in it, and will need to do $user->first()->id.

    You aren't using $user for anything else in the method, so you don't really need that object. You can use the value() method instead to get the id directly from the query.



    public function login()
    {

    $cpf = Request::only('cpf');

    // value() fetches the value of the specified column from the first row of query results
    $id = User::where('cpf', $cpf)->value('id');

    Auth::loginUsingId($id);
    return redirect('/perfil');

    }


    I'm not really sure about the authentication part, though.
