Here we print a log message and store the DBIC ResultSet in

+C<< $c->stash->{resultset} >> so that it's automatically available
for other actions that chain off C<base>. If your controller always
needs a book ID as its first argument, you could have the base method
capture that argument (with C<:CaptureArgs(1)>) and use it to pull the
-book object with C<-E<gt>find($id)> and leave it in the stash for later
+book object with C<< ->find($id) >> and leave it in the stash for later
parts of your chains to then act upon. Because we have several actions
that don't need to retrieve a book (such as the C<url_create> we are
working with now), we will instead add that functionality to a common
request).
Also notice that we are using a more advanced form of C<uri_for> than we
-have seen before. Here we use C<$c-E<gt>controller-E<gt>action_for> to
+have seen before. Here we use C<< $c->controller->action_for >> to
automatically generate a URI appropriate for that action based on the
method we want to link to while inserting the C<book.id> value into the
appropriate place. Now, if you ever change C<:PathPart('delete')> in

If you are referring to a method in the current controller, you can use
-C<$self-E<gt>action_for('_method_name_')>.
+C<< $self->action_for('_method_name_') >>.

If you are referring to a method in a different controller, you need to
include that controller's name as an argument to C<controller()>, as in
-C<$c-E<gt>controller('_controller_name_')-E<gt>action_for('_method_name_')>.
+C<< $c->controller('_controller_name_')->action_for('_method_name_') >>.

Now, any other method that chains off C<object> will automatically have

We can improve the logic by converting to a redirect. Unlike
-C<$c-E<gt>forward('list'))> or C<$c-E<gt>detach('list'))> that perform a
+C<< $c->forward('list')) >> or C<< $c->detach('list')) >> that perform a
server-side alteration in the flow of processing, a redirect is a
client-side mechanism that causes the browser to issue an entirely new
request. As a result, the URL in the browser is updated to match the
Although the sample above only shows the C<content> div, leave the rest
of the file intact -- the only change we made to the C<wrapper.tt2> was
to add "C<|| c.request.params.status_msg>" to the
-C<E<lt>span class="message"E<gt>> line. Note that we definitely want
+C<< <span class="message"> >> line. Note that we definitely want
the "C<| html>" TT filter here since it would be easy for users to
modify the message on the URL and possibly inject harmful code into the
application if we left that off.
We defined the search string as C<$title_str> to make the method more
flexible. Now update the C<list_recent_tcp> method in
C<lib/MyApp/Controller/Books.pm> to match the following (we have
-replaced the C<-E<gt>search> line with the C<-E<gt>title_like> line
