Rails cron 与每当
我不明白为什么“每当”不起作用
Schedule.rb
every 2.minutes do
runner "Ping.check_pings"
end
Ping.rb
class Ping < ActiveRecord::Base
attr_accessible :LAN, :WAN, :info, :infastructure_id
def self.check_pings
@monitor_ping = Ping.new()
@monitor_ping.WAN = "true"
@monitor_ping.save
end
end
crontab -l
0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58 * * * * /bin/bash -l -c 'cd /home/ruben/Monitoring && script/rails runner -e production '\''Ping.check_pings'\'''
Rails runner "Ping.check_pings" ==>在命令行中工作
我尝试在“rails s”中运行我的项目，但没有 我做错了什么？
I don't understand why "whenever" does not work
Schedule.rb
every 2.minutes do
runner "Ping.check_pings"
end
Ping.rb
class Ping < ActiveRecord::Base
attr_accessible :LAN, :WAN, :info, :infastructure_id
def self.check_pings
@monitor_ping = Ping.new()
@monitor_ping.WAN = "true"
@monitor_ping.save
end
end
crontab -l
0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58 * * * * /bin/bash -l -c 'cd /home/ruben/Monitoring && script/rails runner -e production '\''Ping.check_pings'\'''
rails runner "Ping.check_pings"
==> Works in command line
I tried it with my project running in "rails s" and without
What am i doing wrong?

我只是猜测，但是...您是在开发还是生产中进行测试？
如果您正在开发中，请不要忘记安排您的日程安排。rb：
您也可以这样做：
问候

I am just guessing, but... Are you testing on development or production?.
If your are in development, don't forget to put on your schedule.rb:
Also you can do this:

我认为该字符串上的字符转义不正确；看看
生产'\''部分，第一个'关闭了字符串，然后你在没有打开字符串的情况下转义了'。试试这个：或这个：
或这个：（
您可能根本不需要在单个 shell 单词周围加上引号。:)
I think the character escaping is incorrect on this string; look at the
production '\''piece, the first'closes the string, then you're escaping a'without a string being open. Try this:or this:
or this:
(you might not need quotes around the single shell-word at all. :)
