Question

在我的辅导课程模型中，我有一些代码可以在不同时间触发提醒文本。一切正常，直到我尝试了一些重构，现在我遇到了问题。

def send_reminder_text(texts_batch)
    texts_batch.each do |text|
        page_number = Refugee.find(text.refugee_id)[:last_page]
        body_of_text = text[:begin_time].in_time_zone.strftime("Burma Reminder: upcoming session at %I:%M%p beginning on page #{page_number}. 
            Please email jek2141@columbia.edu to reschedule or cancel the session.") 
        text.begin_text(body_of_text)
    end
end

def self.deliver_pm_reminder_text
    texts_batch = TutoringSession.batch_for_pm_reminder_text
    send_reminder_text(texts_batch)
end

def self.deliver_just_before_reminder_text
    texts_batch = TutoringSession.batch_for_just_before_reminder_text
    send_reminder_text(texts_batch)
end

当我调用deliver_just_before_reminder_text函数时，收到以下错误消息：

irb(main):006:0> TutoringSession.send_reminder_text
NoMethodError: undefined method `send_reminder_text' for #<Class:0x00000003cfe5d8>

尽管上面已明确定义了send_reminder_text，但仍然存在这一点。

您的方法声明指定该方法位于TutoringSession类的对象：

def send_reminder_text(texts_batch)

但是你试图将它称为类本身上的方法：

irb(main):006:0> TutoringSession.send_reminder_text

尝试将您的定义更改为：

def self.send_reminder_text(texts_batch)

rails不允许我从另一个方法内部调用方法 - rails一直说这个方法是未定义的
