links will be used instead of full HTML buttons).
+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 automatically generate a URI appropriate for that action while
+inserting the C<book.id> value into the appropriate place. Now, if
+you ever change C<:PathPart('delete')> in your controller method to
+C<:PathPart('kill')>, then your links will automatically update without

To add the C<object> method, edit C<lib/MyApp/Controller/Books.pm>
and add the following code:

sub object :Chained('base') :PathPart('id') :CaptureArgs(1) {
my ($self, $c, $id) = @_;

# Redirect the user back to the list page
- $c->response->redirect($c->uri_for('/books/list'));
+ $c->response->redirect($c->uri_for($self->action_for('list'));
}
$c->stash->{object}->delete;
# Redirect the user back to the list page with status msg as an arg
- $c->response->redirect($c->uri_for('/books/list',
+ $c->response->redirect($c->uri_for($self->action_for('list'),
{status_msg => "Book deleted."}));
