I am following the webcasts and really enjoying them. However, I have hit a point of frustration. When I run the code that is presented in
episode 3 (unless my eyes deceive me, it is exactly as presented in the video), I do not get the same results. When the presenter enters the wrong username and password, he gets "denied," while the correct username and password yeilds "Welcome to Momcorp!" For me, no matter what I enter with the code below, I get "Welcome to Momcorp!" Am I missing something here?
#!/usr/bin/env perl
use Mojolicious::Lite;
# Helpers = in app extensions
helper auth => sub {
my $self = shift;
return 1 if
$self->param('username') eq 'bender' and
$self->param('password') eq 'rodriguez';
};
get '/login' => sub { shift->render('login') };
post '/momcorp' => sub {
my $self = shift;
$self->render(text => 'denied') if !$self->auth;
$self->render(text => 'Welcome to Momcorp!');
};
post '/momcorp/carol' => sub {
my $self=shift;
$self->render(text => 'denied') if !$self->auth;
$self->render(text => 'Welcome, Carol!');
};
app->start;

This version is up to date, have fun!
Later in the video we modify the code to use under and tag helpers. Oddly, this code does work:
#!/usr/bin/env perl
use Mojolicious::Lite;
# Helpers = in app extensions
helper auth => sub {
my $self = shift;
return 1 if
$self->param('username') eq 'bender' and
$self->param('password') eq 'rodriguez';
};
get '/login' => sub { shift->render('login') };
# Under: protects actions listed underneath the under
# Modify behavior of any action under...
# if returns true actions under can be matched
# false, they are inaccessible
# removes duplicate code :)
under sub {
my $self = shift;
return 1 if $self->auth;
$self->render(text => 'denied');
return;
};
post '/momcorp' => sub { shift->render(text => 'Welcome to Momco
+rp!') };
post '/momcorp/carol' => sub { shift->render(text => 'Welcome, Carol!'
+) };
app->start;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
