Question

I am trying to make a custom logger. I read elsewhere that I can define my logger in environment.rb and use it in other files.

I have in environment.rb:

# Load the rails application
require File.expand_path('../application', __FILE__)

my_logger = Logger.new("#{Rails.root}/log/my.log")
my_logger.formatter = Logger::Formatter.new


# Initialize the rails application
MyApp::Application.initialize!

And I call the logger from, for example, a controller:

    my_logger.info "got here"

However, I obtain the error:

Undefined local variable or method `my_logger’ for

Any clues as to why this could be happening? Thanks!

Open file into writing/appending mode :

Try :

logfile = File.open('#{Rails.root}/log/my.log', 'a')  
my_logger = Logger.new(logfile)
my_logger.info 'Hello World!'
