[dancer-users] Question about Perl Dancer Framework

[Sawyer X]

Hi Jean-Marie.

Welcome! :)

Let's go over the code you showed.

> get '/index' => sub { template 'index' };

That will declare a path "/index" for a GET request which will render a
template called (if you're using the default templating framework) "index.tt".
So far so good.

> get '/' => sub { template 'login' };

When someone goes to the main page, render 'login.tt'.

> get 'test' => sub {
>     template 'test';
> };

You probably want to change this to "get '/test'" instead of "get 'test'".
Paths should begin with "/", almost always.

>                #return '<script> document.location("./views/test.tt
");</script>';

In this case, you want to simply use "redirect" keyword which would do this
for you:
get '/test' => sub {
    redirect "/"; # redirect to main page
};

In your example, you're trying to redirect to "./views/test.tt" which is a
file. HTTP redirects are for *paths*, not *files*.

If you want people who go to "/wrong/place" to go to "/test" which renders
the right template ("test.tt"), you would write this:
get '/wrong/place => sub { redirect '/test' };
get '/test => sub { template 'test'; }

Does this help?
