Problem with index.tt2

[David Silva]

Hi again,

I'm following the book "Catalyst - Accelerating Perl Web Application Development" by Jonathan Rockway (2007) with Catalyst 5.80013.

And in chapter 3 the autor says to create an index.tt2 page and said that we don't need to do nothing cos Catalyst will recognize the index. I start the server and it shows me the default page of catalyst.

I'm following the book, so what i done wrong?

Thanks once again!

"we don't need to do nothing" parses as "we need to do something."


Specifically, you missed:

TEMPLATE_EXTENSION => '.tt2'


also, this book has some errata:

My guess would be that you haven't changed the template extension.  See
if index.tt works.  From my recollection, the book is building on top of
the previous example and only references some of the previously covered
material rather than explicitly going through it again (so also make
sure you have the view set up).

As a note, it's not that Catalyst "recognizes the index", it's that the
view defaults to trying to display a template matching the present
action (which in this case should be "index") with the template
extension appended.

Good Morning,

I already had set TEMPLATE_EXTENSION => '.tt2', and i solve the problem by changing the controller Root.pm like this:

sub index :Path :Args(0) {
    my ( $self, $c ) = @_;

    # Hello World
#    $c->response->body( $c->welcome_message );
     $c->stash->{template} = 'index.tt2';
}

Thank you

Doh...If you were getting the welcome screen it _would_ have been that
line left over.  The other suggestions would have been in the case of an
error screen.

The book is referencing the fact that you don't need to set the template
stash variable in this case, but explicitly specifying things is never a
bad idea, especially when the default behavior is unclear or uncertain.  
Ironically the TEMPLATE_EXTENSION is irrelevant with the above setup.
