  1. Challenge

    Access Log

    Overview

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

    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. ### Solution The solution can be found in the solution directory.

  2. Challenge

    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.

  3. Challenge

    Unauthorized Log

    In this module we'll create a signal that writes unauthorized login attempts to a log file.
