"Correct" way to write log output from a background (Resque) job?

Resque jobs are just plain old ruby objects. I can use puts calls inside them to produce output into the console, or I can instantiate a standard Ruby Logger class with STDOUT and use that.

But is开发者_开发百科 there a correct approach to logging in Rails, from places that aren't controllers or models? I see Rails.logger returns a BufferedLogger, but when I call info or warn etc on it, nothing happens. If I call flush on it, it just returns an empty array and nothing is output.

What's the convention here?

I'm not really sure that there is a convention. I had a pretty ugly logging system up until just recently. Now I use lumber to integrate log4r with Rails. That really made logging much nicer because I now have named loggers (e.g., logger matches the class name -- great for filtering output) and I can control log levels on a per-logger (i.e., per-class) basis.

There's also a GELF adapter for log4r if you want to use graylog2 to aggregate your logs.
