Add Error Handling to a Flask CMS

What you'll learn

Python & Flask are great for building a web applications. In this project you’ll utilize logging, signals and error handlers to make an existing content management system more resilient.

Table of contents

  • Set up your local environment for projects. We'll walk you through everything you need to know, including how to install and configure your environment to be able to complete all of the tasks.
Access Log
  • In this module we'll create a function to configure logging. The function creates and configures a rotating file handler. This function will then be used to configure an access log. Then using an after request decorator we'll write all requests to this access log.
Error Log
  • In this module we'll handle 404 and 500 errors. When these errors happen the user will be redirected to the appropriate template. The 500 errors will also be logged to an error log.
Unauthorized Log
  • In this module we'll create a signal that writes unauthorized login attempts to a log file.
