Rails automatically logs information to log files and maintains different log files for each environment. Take a look at the information logged by default and learn to configure the types of data which get logged. Learn how to write custom information to the log files to assist with record keeping or debugging.
- [Instructor] In this movie, we'll take a look at the…log files that Rails uses.…We'll learn how to configure them…and write our own information to them.…Note that the log files I'm referring to here…are the application logs, which are different…from your web server logs.…Basic request data and any errors which occur…before requests get to the Rails application…are going to show up in the server logs.…But the web server only knows about the request…that comes in and the data that it sends back.…Everything that happens once it hands off the request…to the Rails application remains a mystery…to the web server.…
But the Rails log files can provide lots of rich detail…about what happens as Rails processes the request.…The place that you'll find log files…is in the log directory,…and then you'll find a different log file…for each environment; so development,…production, and test.…If you haven't activated those other environments yet,…then those log files just won't be there.…At the moment, you probably only have one for development.…
