无法在rails 3中使用cronjob [英] Unable to run cronjob using whenever in rails 3

问题描述

我按照所有步骤，参考 https://github.com/javan/whenever

in schedule.rb

  require'yaml'
 set：environment，'production'
 set：output，{
：error => /log/error.log，
：standard => /log/cron.log
} 
 
 every 1.minute do 
 runnerUser.weekly_update
 end 
  
 
 
 ，：require => false 
 
 
某些命令的输出
 
 
 
 localhost ：〜/ project $ when -i 
  [write] crontab文件更新
  
 localhost：〜/ project $ crontab -l <​​/ p> 
 
 
  ＃Begin每当生成的任务：/home/bacancy/project/config/schedule.rb 
 * * * * * / bin / bash -l -c'cd / home / bacancy / project& script / rails runner -e production'\'User.weekly_update'\''>> /log/cron.log 2> /log/error.log'
 
＃结束每当生成的任务：/home/bacancy/project/config/schedule.rb 
 
＃开始每当生成的任务：store 
 * * * * * / bin / bash -l -c'cd / home / bacancy / project&&脚本/ rails runner -e开发'\''User.weekly_update'\'''
 
＃结束每当生成的任务：store 
 
＃开始每当生成的任务for：lapulguilla 
 
＃End每当生成的任务：lapulguilla 
  
我输入
 
 
 
 localhost：〜/ project $ every 
  * * * * * / bin / bash -l -c'cd / home / bacancy / project&& script / rails runner -e production'\'User.weekly_update'\''>> /log/cron.log 2> /log/error.log'
 
 ## [message]上面是你的日程表文件转换为cron语法;您的crontab文件没有更新。 
 ## [message]运行`whatever --help'获取更多选项。 
 
在用户模型中有自定义self.weekly_update 
  def self.weekly_update 
 puts每分钟调用cronjobs
 end 
  
 
 
解决方案
你的一切是正确的，它只是你正在说cron工作在背景打印的东西，所以它是这样做和你
 
 
 
相反，你应该尝试创建或销毁一些记录来感受我认为的改变：）
 
i follow all the steps for whenever with reference to https://github.com/javan/whenever 

in schedule.rb
require 'yaml'
set :environment, 'production'
set :output, {
    :error    => "/log/error.log",
    :standard => "/log/cron.log" 
}

every 1.minute do
   runner "User.weekly_update"
end
in gemfile 
gem 'whenever', :require => false
output of some command

localhost:~/project$ whenever -i
[write] crontab file updated
localhost:~/project$ crontab -l
# Begin Whenever generated tasks for: /home/bacancy/project/config/schedule.rb
* * * * * /bin/bash -l -c 'cd /home/bacancy/project && script/rails runner -e     production '\''User.weekly_update'\'' >> /log/cron.log 2>> /log/error.log'

# End Whenever generated tasks for: /home/bacancy/project/config/schedule.rb

# Begin Whenever generated tasks for: store
* * * * * /bin/bash -l -c 'cd /home/bacancy/project && script/rails runner -e  development '\''User.weekly_update'\'''

# End Whenever generated tasks for: store

# Begin Whenever generated tasks for: lapulguilla

# End Whenever generated tasks for: lapulguilla
and then i type 

localhost:~/project$ whenever
* * * * * /bin/bash -l -c 'cd /home/bacancy/project && script/rails runner -e    production '\''User.weekly_update'\'' >> /log/cron.log 2>> /log/error.log'

## [message] Above is your schedule file converted to cron syntax; your crontab file  was not updated.
## [message] Run `whenever --help' for more options.
In User model i have definition self.weekly_update
def self.weekly_update
  puts "cronjobs is called in every minutes"
end 

解决方案
Your everything is correct, its just that you are saying to cron job to print something in background, so it is doing that and you are able to observe it.

Instead you should try create or destroy some records to feel the changes i think :)
