Chapter 12: A challenge

After working through this book, you should be ready to build a simple web application on your own. Here is a challenge: add a guestbook to Watchlist, similar to SayHello.

Some suggestions to get you started:

• Define a model for messages and update the database tables.
• Create a template for the guestbook page.
• Add a message form to the template.
• Create a view to display the guestbook page.
• Handle form submissions in that view.
• Generate sample data for testing.
• Write unit tests.
• Update the deployed application.
• Consult the SayHello source code if you need an example.

If you get stuck, start a discussion in the Code Kitchen community, using the “Flask 入门教程” (Flask for Beginners) category.
