爲什麼DelayedJob忽略了delayed_job_config.rb？

Question

我有以下幾點：這裏

/config/delayed_job_config.rb

# Enable DelayedJob Logging 
Delayed::Worker.logger = Rails.logger 
Delayed::Worker.logger.auto_flushing = 1 

# Do not delete failed jobs (default is true) 
Delayed::Worker.destroy_failed_jobs = false 

# Dont wait so long between jobs 
Delayed::Worker.read_ahead = 100 # default was 5 
Delayed::Worker.sleep_delay = 1 #default was 5 

問題是沒有被使用的設置：

$ rails c 
Loading development environment (Rails 3.2.5) 
1.9.3-p125 :001 > Delayed::Worker.read_ahead 
=> 5 
1.9.3-p125 :002 > Delayed::Worker.sleep_delay 
=> 5 

任何想法有什麼不對嗎？由於

配置進去：

config/initializers/delayed_job_config.rb
