Another thing is I would like to get rid off the ‘Completed in..’ line in the logs, because I don’t need benchmarks for my application. I am benchmarking using around filters and the log entries are unnescessary.

actionpack/lib/action_controller/benchmarking.rb has the code that does the benchmarking, I’m unable to override it for some reason after multiple attempts.

Please send me an email if you do find a work-around.
Thanks!

Also requiring in environment.rb is unnecessary.
Placing ‘extensions.rb’ in the lib folder automatically loads/requires it when RAILS boots.

Happy hacking

I used the same technique before coming to this page..
but one of the reasons I feel this is fragile is because its rails-version-dependent, so when you migrate to a newer rails version in the future, and log_processing expects different parameters or instance variables, then everything breaks and you have to rewrite log_processing.

Neverthless a handy trick.

I have similar overrides for several rails such functions including ones for benchmarking and exception handling

Rails is beautiful because ruby is beautiful. Try doing this in Python or Perl!

I used this technique to _add_ http referer logging to Rails. Seems to work nicely. Or something sort of like this technique:

application.rb:
def log_processing
super
if logger && logger.info?
logger.info(” HTTP Referer: #{request.referer[0..100]}”)
end
end

This is a helpful post! I came upon it because I was looking for a way to not log anything for entire controllers. I ended up defining and empty “logger” method for each “silent” controller, but this post will help me tweak my logs in the future. Thanks!
