I have some helper methods on my ActiveSupport::BufferedLogger such as displaying KeyValue pairs, it all works fine from rails s but fails in rails c
In rails s, I can see that my Logger extends BufferedLogger and that is the class I have chosen to MonkeyPatch, I have also tested this out with ActiveSupport::Logger as well.
I had thought that rails c ran through the same initializers that rails s used, am I wrong in thinking that?
Do I need to run some sort of initializer when starting rails c?
Location of my file is:
Error is here:
Sample Snippet listed here
class ActiveSupport::BufferedLogger
def kv(key, value)
info('%-50s %s' % ["#{key}: ".brown, value])
end
def line
info(@@l.brown)
end
def block(message)
line
info(message)
line
end
end
I recommend subclassing ActiveSupport::Logger
(or ActiveSupport::BufferedLogger
if you really want though it's deprecated in Rails 4) instead of monkey-patching. Rails provides a configuration option to override the logger instance used by the app. This works in any context that loads the Rails environment, including the server and console.
There are a number of ways you can do this; a quick and dirty way to get you started is to just define the class and set the logger instance in an initializer that will get loaded during the initialization process of the Rails environment:
# config/initializers/my_logger.rb
class MyLogger < ::ActiveSupport::Logger
# additional methods and overrides
end
Rails.logger = MyLogger.new(Rails.root.join("log", "#{Rails.env}.log"))
