How to log something in Rails in an independent log file?

Question

In rails I want to log some information in a different log file and not the standard development.log or production.log. I want to do this logging from a model class.

Answer 1

class Post < ActiveRecord::Base
    def initialize(attributes)
        super(attributes)
        @logger = Logger.new("#{Rails.root}/log/post.log")
    end

    def logger
        @logger
    end

    def some_method
        logger.info('Test 1')
    end
end

ps = Post.new
ps.some_method
ps.logger.info('Test 2')
Post.new.logger.info('Test 3')
