actionmailer - Rails 3.1RC4 Mailer 邮件方法返回错误数量的参数(0 代表 1)

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，但一些调试/规范确认错误发生在 mail(:to) 行上。整个跟踪如下，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 中保释的方法

assign_controller(controller)

有什么想法或建议吗？我也尝试过 RC5，结果相同。

谢谢!

我遇到过同样的问题。好像ActionMailer::Base不喜欢你使用 request发送电子邮件的方法。更改方法的名称，它将起作用。
