Ruby On Rails log file name and line number

Question

Right now, I use log4r for logger in Rails to print file name and line number:

======== config/log4r.yml ========

log4r_config:
  # define all loggers:
  loggers:
    - name          : rails
      level         : DEBUG
      trace         : 'true'
      outputters    : 
      - console

  # define all outputters (incl. formatters)
  outputters:
  - type: StdoutOutputter
    name: console
    formatter:
      date_pattern: '%Y-%m-%d %H:%M:%S'
      pattern     : '%d %l %t : %m'
      type        : PatternFormatter

However it prints file path instead of filename, and it's too long:

2015-12-23 18:05:37 INFO /Users/fudy/Workspace/RubyWorkspace/HelloWorld/app/controllers/welcome_controller.rb:3: in `index' : hello

But I want this format:

2015-12-23 18:05:37 INFO welcome_controller.rb:3: hello

Is there any solution?

Are you sure this is the pattern you use? It looks more like '%d %p %t : %m' am I right? — shem, Dec 23 '15 at 10:22
Sorry, thought you're using log4j and not log4r. See my answer — shem, Dec 24 '15 at 07:01

It doesn't show in the documentation but from looking at the code you can see that you should replace "t" with "T" to get only the file name.

The other option is to implement custom formatting like explained here
