Although the a use of flash above is certainly an improvement over the
C<status_msg> we employed in Part 4 of the tutorial, the C<status_msg

+|| c.flash.status_msg> statement is a little ugly. A nice
alternative is to use the C<flash_to_stash> feature that automatically
copies the content of flash to stash. This makes your code controller
and template code work regardless of where it was directly access, a
L<http://localhost:3000/books/list> in your browser. Delete another
of the "Test" books you added in the previous step. Flash should still
maintain the status message across the redirect even though you are no

This tells Catalyst to start using one new plugin:
application. Also take a look at C<lib/MyApp/View/TT.pm> for config
values set by the C<TTSite> helper.
-B<TIP>: Note that TTSite does one thing that could confuse people who
-are used to the normal C<TT> Catalyst view: it redefines the Catalyst
-context object in templates from its usual C<c> to C<Catalyst>. When
-looking at other Catalyst examples, remember that they almost always use
-C<c>. Note that Catalyst and TT I<do not complain> when you use the
-wrong name to access the context object...TT simply outputs blanks for
-that bogus logic (see next tip to change this behavior with TT C<DEBUG>
-options). Finally, be aware that this change in name I<only>
-applies to how the context object is accessed inside your TT templates;
-your controllers will continue to use C<$c> (or whatever name you use
-when fetching the reference from C<@_> inside your methods). (You can
-change back to the "default" behavior be removing the C<CATALYST_VAR>
-line from C<lib/MyApp/View/TT.pm>, but you will also have to edit
-C<root/lib/config/main> and C<root/lib/config/url>. If you do this, be
-careful not to have a collision between your own C<c> variable and the
-Catalyst C<c> variable.)
-
B<TIP>: When troubleshooting TT it can be helpful to enable variable
C<DEBUG> options. You can do this in a Catalyst environment by adding
a C<DEBUG> line to the C<__PACKAGE__->config> declaration in
C<lib/MyApp/View/TT.pm>:
__PACKAGE__->config({
- CATALYST_VAR => 'Catalyst',
...
DEBUG => 'undef',
