pcouderc has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks, I am trying to authenticate and I success : 
sub startup {
    my $self = shift;
    my $r = $self->routes;
    $r->get('/:layout')->to('login#nolog');
    $r->get('/:layout/logout')->to('login#logout');
    my $auth = $r->under( sub { return defined($self->session('userid'
+)) } );
    $auth->get('/:layout/menu')->to('login#menu');
    $r->any('/:layout/:dummy')->to('login#nolog');}

I authenticate in Login.pm sub nolog, I define userid and I redirect to "upsmichel/menu", I expect "login/menu.html.ep" to be rendered but instead I am routed to a callback ?
why ? What do I miss ?
Thanks

    Can you maybe show us a small, self-contained example that we can use to replicate your problem? Something that has a minimal login/menu.html.ep and the minimal code to reproduce?

      Mmm, minimum, it is trivial with : Login.pm 
      package Myapp::Controller::Login;
use Mojo::Base 'Mojolicious::Controller';
sub nolog {
  my $c = shift;
  $c->session(userid => 1);
  $c->redirect_to('menu');
}
1;

      and nolog.htlm.rp : 
      %= form_for nolog => (method => 'POST') => begin
  <p>
  % if (param 'user') {
    <b>Erreur dans le mot de passe ou le nom d'utilisateur. Veuillez r
+éessayer</b><br>
  % }
  Utilisateur :<br>
  %= text_field 'user'
  <br>Mot de passe :<br>
  %= password_field 'pass'
  <br>
  %= submit_button 'Login'
  </p>
% end

      and login.htlm.ep : 
      
<p>
...

      Self contained, I do not know how to do (I am not with Mojolicious::Lite)..

        Does Class "MyApp::Controller::Login" is not a controller mean anything to you?

    "Routing to a callback" means calling a "sub { ... }" instead of a to('somecontroller#someaction'). If you give it a name it will print the name instead of just "a callback". (conversely, you can embed any of them with a sub{} callback instead of a name and it will say just "Routing to a callback" instead of "Routing to controller/action".

    It is probably calling your $r->under() sub and failing.
