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 have spent a whole chapter looking at validation, but if you look at the major companies that have faced information security breaches over the last few years, you'll agree that security is worth spending some time on. We looked specifically at cross-site scripting or XSS attacks, but we also discussed some more general points of input validation. This takes us to the end of our second project.

One thing that is notably missing is to work out who added which crimes. If one malicious user adds a bunch of bogus crimes to our database, they could potentially mess up our entire dataset!

In our next project, we'll look at authenticating users through a User Account Control system, which will give us more control over who we let on our site and what they can do.
