+
+Although the query parameter technique we used in
+L<Chapter 4|Catalyst::Manual::Tutorial::04_BasicCRUD> and the C<flash>
+approach we used above will work in most cases, they both have their
+drawbacks.  The query parameters can leave the status message on the
+screen longer than it should (for example, if the user hits refresh).
+And C<flash> can display the wrong message on the wrong screen (flash
+just shows the message on the next page for that user... if the user
+has multiple windows or tabs open, then the wrong one can get the
+status message).
+
+L<Catalyst::Plugin::StatusMessage> is designed to address these
+shortcomings.  It stores the messages in the user's session (so they are
+available across multiple requests), but ties each status message to a
+random token.  By passing this token across the redirect, we are no
+longer relying on a potentially ambiguous "next request" like we do with
+flash.  And, because the message is deleted the first time it's
+displayed, the user can hit refresh and still only see the message a
+single time (even though the URL may continue to reference the token,
+it's only displayed the first time).  The use of C<StatusMessage>
+or a similar mechanism is recommended for all Catalyst applications.
+
+To enable C<StatusMessage>, first edit C<lib/MyApp.pm> and add
+C<StatusMessage> to the list of plugins:
+
+    use Catalyst qw/
+        -Debug
+        ConfigLoader
+        Static::Simple
+    
+        StackTrace
+    
+        Authentication
+    
+        Session
+        Session::Store::File
+        Session::State::Cookie
+    
+        StatusMessage
+    /;
 
-Although the a use of flash above works well, 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 controller
-and template code work regardless of where it was directly access, a
-forward, or a redirect.  To enable C<flash_to_stash>, you can either
-set the value in C<lib/MyApp.pm> by changing the default
-C<__PACKAGE__-E<gt>config> setting to something like:
+Then edit C<lib/MyApp/Controller/Books.pm> and modify the C<delete>
+action to match the following:
 
-    __PACKAGE__->config(
-            name    => 'MyApp',
-            session => {flash_to_stash => 1}
-        );
+    sub delete :Chained('object') :PathPart('delete') :Args(0) {
+        my ($self, $c) = @_;
+    
+        # Saved the PK id for status_msg below
+        my $id = $c->stash->{object}->id;
+    
+        # Use the book object saved by 'object' and delete it along
+        # with related 'book_authors' entries
+        $c->stash->{object}->delete;
+    
+        # Redirect the user back to the list page
+        $c->response->redirect($c->uri_for($self->action_for('list'),
+            {mid => $c->set_status_msg("Deleted book $id")}));
+    }
+
+This uses the C<set_status_msg> that the plugin added to C<$c> to save
+the message under a random token.  (If we wanted to save an error
+message, we could have used C<set_error_msg>.)  Because
+C<set_status_msg> and C<set_error_msg> both return the random token, we
+can assign that value to the "C<mid>" query parameter via C<uri_for> as
+shown above.
+
+Next, we need to make sure that the list page will load display the
+message.  The easiest way to do this is to take advantage of the chained
+dispatch we implemented in
+L<Chapter 4|Catalyst::Manual::Tutorial::04_BasicCRUD>.  Edit
+C<lib/MyApp/Controller/Books.pm> again and update the C<base> action to
+match:
+
+    sub base :Chained('/') :PathPart('books') :CaptureArgs(0) {
+        my ($self, $c) = @_;
+    
+        # Store the ResultSet in stash so it's available for other methods
+        $c->stash(resultset => $c->model('DB::Book'));
+    
+        # Print a message to the debug log
+        $c->log->debug('*** INSIDE BASE METHOD ***');
+    
+        # Load status messages
+        $c->load_status_msgs;
+    }
 
-B<or> add the following to C<myapp.conf>:
+That way, anything that chains off C<base> will automatically get any
+status or error messages loaded into the stash.  Let's convert the
+C<list> action to take advantage of this.  Modify the method signature
+for C<list> from:
 
-    <session>
-        flash_to_stash   1
-    </session>
+    sub list :Local {
 
-The C<__PACKAGE__-E<gt>config> option is probably preferable here
-since it's not something you will want to change at runtime without it
-possibly breaking some of your code.
+to:
 
-Then edit C<root/src/wrapper.tt2> and change the C<status_msg> line
+    sub list :Chained('base') :PathPart('list') :Args(0) {
+
+Finally, let's clean up the status/error message code in our wrapper
+template.  Edit C<root/src/wrapper.tt2> and change the "content" div
 to match the following:
 
-    <span class="message">[% status_msg %]</span>
+    <div id="content">
+        [%# Status and error messages %]
+        <span class="message">[% status_msg %]</span>
+        <span class="error">[% error_msg %]</span>
+        [%# This is where TT will stick all of your template's contents. -%]
+        [% content %]
+    </div><!-- end content -->
+
+Now go to L<http://localhost:3000/books/list> in your browser. Delete
+another of the "Test" books you added in the previous step.  You should
+get redirection from the C<delete> action back to the C<list> action,
+but with a "mid=########" message ID query parameter.  The screen should
+say "Deleted book #" (where # is the PK id of the book you removed).
+However, if you hit refresh in your browser, the status message is no
+longer displayed  (even though the URL does still contain the message ID
+token, it is ignored -- thereby keeping the state of our status/error
+messages in sync with the users actions).
 
-Restart the development server and go to
-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
-longer explicitly accessing C<c.flash>.
