Developing an Error Logging Framework for Ruby on Rails Application Using AOP

A framework for detecting and recording the flaws that happen during the usage of web applications is designed and a library functionality to perform this is discussed in this paper. The recorded information can be stored at different levels of detail, commonly called the logging levels. For some modules more than others, it may be required to store more detailed information about any error that arises during its usage according to its importance. A Web Application also needs to print the stack trace containing the error information on the web page when an error occurs for the user to understand the nature of the error. When dealing with legacy web applications, it is difficult to insert code. The proposed and designed framework is tested with a web application called Kic Kart.
