[Dancer-users] Dancer::Plugin::Auth::RBAC Application

[Christopher Taranto]

Hi Fontardion,

I think the problem you are encountering is that you are getting confused
about the reference to the auth plugin and using the plugin method directly.

Try this:

  get '/' => sub {
  if (auth->asa('guest') ) {
    redirect '/login';
  }
  else {
    template 'index';
  }
};

post '/login' => sub {
    my $auth = auth(params->{username}, params->{password});
    if (! $auth->errors) {
      flash ok => 'Login ok';
      redirect '/';
    }
    else {
      flash error => 'Login Error';
      redirect '/login';
    }

};

get '/logout' => sub {
    auth->revoke();
    flash ok => 'Session Closed';
    redirect '/';
};
