Summary
In this chapter, we completed our Waiter Caller web application. We installed MongoDB on our server, learned how to use it through the shell, and then installed PyMongo. Using PyMongo, we created a new database helper class to allow our application code to run operations on the new database.
Finally, we added a favicon to make our web application friendlier and more aesthetically pleasing to users.
In the next and final chapter, we'll take a look at what could still be added to our application to improve usability and security and end with some pointers on where to look next to continue learning about Flask and web development through Python.
