我尝试使用随时随地创建一个cron作业向用户发送生日提醒,我希望每天都能运行这个cron。
我有任何宝石工作,但我的cron工作一直错误。我试图在rails控制台中调用控制器方法来解决它,但我一直在收到错误,我不确定原因。
我有这个控制器:
class BirthdayRemindersController < ApplicationController
include ApplicationHelper
# cron job that sends birthday reminders
def send_birthday_email_reminders
users = User.all
email_addresses = []
users.each_with_index do |user, i|
if user.user_details.birthday_reminders == true
email_addresses[i] = get_primary_email(user)
end
end
p email_addresses
users.each do |user|
if user.user_details.birthday == Date.today
p "reminder sent"
send_birthday_reminders(user, email_addresses)
end
end
end
end
在rails控制台中,我已尝试过这两种方法,但两者都出错了。

我缺少什么?我没有为此控制器定义路线,因为我不希望任何人能够通过网络眉毛击中它

控制器上的方法是实例方法,而不是类方法。类方法使用self.
定义。很难从控制台触发控制器操作,因为您错过了整个上下文。您没有会话,没有请求,没有响应。所有这些都使得难以使用控制器操作中的代码。如果您需要从外部触发代码(控制台,机架任务,其他代码)。你应该将代码提取到它自己的类中。
