Ruby on Rails writing ActiveJob sub-class logs to a desired file

Question

Ruby : 2.3.2

Rails: 5.0.0.1

I have following classes

class JobA < ApplicationJob
  def perform(args)
    Rails.logger.debug "JobA log"

    if condition_1
      JobB.perform_later(args)
    else
      JobC.perform_later(args)
    end
  end
end

class JobB < ApplicationJob
  def perform(args)
    Rails.logger.debug "JobB log"
  end
end

class JobC < ApplicationJob
  def perform(args)
    Rails.logger.debug "JobC log"
  end
end

class RecurringJob
  def perform
    JobA.perform_later(args)
  end
end

I desire to redirect logs written by each of JobA, JobB, JobC classes to a desired file. However it is not working.

I tried following

/config/initializers/logging.rb

# Reference: https://stackoverflow.com/a/44168717/936494
class SelectedJobsLogger
  LOG_FILE_PATH = Rails.root.join('log', 'selected_jobs.log')
  class << self
    cattr_accessor :logger
    delegate :debug, :info, :warn, :error, :fatal, :to => :logger
  end
end

module SelectedJobsLogHelpers
  LOGGER_CLAZZ = SelectedJobsLogger

  private

  def log_debug_message(msg)
    LOGGER_CLAZZ.debug(msg)
  end
end

SelectedJobsLogger.logger = ActiveSupport::TaggedLogging.new(ActiveSupport::Logger.new(logger_clazz::LOG_FILE_PATH))
SelectedJobsLogger.logger.level = Rails.logger.level

And then updated my job classes in following manner

class JobA < ApplicationJob
  include SelectedJobsLogHelpers

  def perform(args)
    log_debug_message "JobA log"

    if condition_1
      JobB.perform_later(args)
    else
      JobC.perform_later(args)
    end
  end
end

class JobB < ApplicationJob
  include SelectedJobsLogHelpers

  def perform(args)
    log_debug_message "JobB log"
  end
end

class JobC < ApplicationJob
  include SelectedJobsLogHelpers

  def perform(args)
    log_debug_message "JobC log"
  end
end

With that in place only "JobA log" is getting written to log/selected_jobs.log and JobB log and JobC log are getting written to log/development.log

log/selected_jobs.log

JobA log

log/development.log

Also as can be seen in log/selected_jobs.log the job logs are not written in the format like they are getting written in format log/development.log. I need the logs in former file to be written in the same format as they are in latter.

Can anybody please help me achieving the desired thing?
