I am hoping someone can help me understand how to get this to work as a POST instead of GET.
When I do sub below as 'get' it works but when I replace 'get' with 'post' I get:

--2015-08-06 13:52:05--  http://0.0.0.0:3000/user
Connecting to 0.0.0.0:3000... connected.
HTTP request sent, awaiting response... 404 Not Found
2015-08-06 13:52:05 ERROR 404: Not Found.

package MyApp;
use Dancer ':syntax';
use Dancer::Plugin::FormValidator;

our $VERSION = '0.1';

post '/user' => sub {

   my $input_hash = {  

       FName => param('firstname'),  
       LName => param('lastname'),
       Email => param('email'),
       Terms => param('terms'),

   }; 

   my $number_of_defined_values = scalar grep { defined } values %{$input_hash};
   $number_of_defined_values = $number_of_defined_values + 0;

   if ($number_of_defined_values > 1) {

         my $error = form_validator_error( 'profile_user', $input_hash );

        if ( ! $error ) {
            #the user provided complete and validates data it's cool to proceed

        } else {

	     my %hash = %$error;
	     foreach my $k (keys %hash) {
	    	 return "$k: $hash{$k}\n";

	     }

	}
   }

   template 'user';

##########################################################
}; ### end of sub user ###################################

true;

Thanks in advance for any help.
