Flask By Example

Overview of this book

This book will take you on a journey from learning about web development using Flask to building fully functional web applications. In the first major project, we develop a dynamic Headlines application that displays the latest news headlines along with up-to-date currency and weather information. In project two, we build a Crime Map application that is backed by a MySQL database, allowing users to submit information on and the location of crimes in order to plot danger zones and other crime trends within an area. In the final project, we combine Flask with more modern technologies, such as Twitter's Bootstrap and the NoSQL database MongoDB, to create a Waiter Caller application that allows restaurant patrons to easily call a waiter to their table. This pragmatic tutorial will keep you engaged as you learn the crux of Flask by working on challenging real-world applications.

Summary


We've fleshed out our application's functionality, and it's now a lot more powerful. We added Dashboard and Account pages, and wrote all the application code, database code, and frontend code to handle our requirements.

We looked at Jinja templates as a way to avoid duplicating the frontend code, and we also looked at how to use the bitly API to shorten links.

We then added WTForms, and saw how this could make our user feedback easier, our forms easier to validate, and our web application more secure. Our users are now kept up-to-date with information about their registration, login, and usage of the application.

In the next chapter, we'll add a real database to our code and then work on some finishing touches.
