How do I use a custom log for my rake tasks in Ruby on Rails?

I have a rake task that calls functions like this:

namespace :blah do
    task :hello_world => :environment do
       logger.info("Hello World")
       helloworld2
    end
end

def helloworld2
   logger.info("Hello Again, World")
end

I want the log output to a custom log, and I really don't want to have to pass a log reference every time I make a function call. I found this somewhere (can't find it again):

def logger
  @@logger ||= Logger.new("#{RAILS_HOME}/log/blah.log")
end

But this does not work for me and I am not sure what it even does because I grabbed the code a long time ago and haven't used it until now. I can't search for @@ on google (tried +"@@" rails) to see what it does. Any help on this issue would be great. I am hoping for a quick solution and not having to install a gem or plugin (unless there is a really really good reason to.

Thanks!

rake disables logging in production mode. make sure you're running in development mode if you want it to log

Advanced Rails Recipes Recipe 84 from @topfunky shows how to define a custom logger. He has some code in the environment config file (production would look like this): RAILS_ROOT/config/environments/production.rb:

config.logger = RAILS_DEFAULT_LOGGER = Logger.new(config.log_path)

I'd test that out instead of redefining the class variable as you have. He might have something on http://nubyonrails.com to check as well.

  1. What do you mean by "does not work for me"? I just tried this same code and it worked - created a new log file and put some text in it.
  2. @@logger is a class variable, it's a language issue, not Rails' one. I believe there's no need in further explanations :)
  3. You've probably mistaken typing "function helloworld2" :)
