Question

我有一个非常标准的邮件程序类，使用以下方法：

def request(contact_us)
  @contact = contact_us
  mail(:to => "customercare@our_co.com", :subject => @contact.subject, :from => @contact.email)
end

我得到的错误是：

wrong number of arguments (0 for 1)

我的第一个想法是传入的参数，但是一些调试/规范确认错误发生在邮件的行上（：to。整个跟踪在下面，第9行是定义方法的地方，第11行是邮件方法。我查看了rails代码，这是实际上在ActionView :: Base中躲避的方法

assign_controller(controller)

有什么想法或建议吗？我也尝试过RC5，结果相同。

谢谢！

我有同样的问题。似乎ActionMailer::Base不喜欢您使用request方法发送电子邮件。更改方法的名称，它将起作用。
