Some things you should note in the output above:
By default, C<Catalyst::View::TT> will look for a template that uses the
same name as your controller action, allowing you to save the step of
manually specifying the template name in each action. For example, this
-would allow us to remove (or comment out) the
+would allow us to remove the
C<$c-E<gt>stash-E<gt>{template} = 'books/list.tt2';> line of our
C<list> action in the Books controller. Open
-C<lib/MyApp/Controller/Books.pm> in your editor and update it to
-match the following:
+C<lib/MyApp/Controller/Books.pm> in your editor and comment out this line
+to match the following (only the C<$c-E<gt>stash-E<gt>{template}> line
+has changed):
=head2 list
# stash where they can be accessed by the TT template
$c->stash->{books} = [$c->model('MyAppDB::Book')->all];
- # Automatically look for a template of 'books/list.tt2' template
- # (if TEMPLATE_EXTENSION is set to '.tt2')
+ # Set the TT template to use. You will almost always want to do this
+ # in your action methods (actions methods respond to user input in
+ # your controllers).
+ #$c->stash->{template} = 'books/list.tt2';
}
C<Catalyst::View::TT> defaults to looking for a template with no
previous section and access the L<http://localhost:3000/books/list>
as before.
-Although this can be a valuable technique to establish a default
-template for each of your actions, the remainder of the tutorial
-will manually assign the template name to
-C<$c-E<gt>stash-E<gt>{template}> in each action in order to make
-the logic as conspicuous as possible.
+B<NOTE:> Please note that if you use the default template technique,
+you will B<not> be able to use either the C<$c-E<gt>forward> or
+the C<$c-E<gt>detach> mechanisms (these are discussed in Part 2 and
+Part 8 of the Tutorial).
+
+
+=head1 RETURN TO A MANUALLY-SPECIFIED TEMPLATE
+
+In order to be able to use C<$c-E<gt>forward> and C<$c-E<gt>detach>
+later in the tutorial, you should remove the comment from the
+statement in C<sub list>:
+
+ $c->stash->{template} = 'books/list.tt2';
+
+Then delete the C<TEMPLATE_EXTENSION> line in
+C<lib/MyApp/View/TT.pm>.
+
+You should then be able to restart the development server and
+access L<http://localhost:3000/books/list> in the same manner as
+with earlier sections.
