错号arg的对色器件电子邮件(wrong number of arg for devise emai

我以前还没有遇到过，但因为我的移动轨道站点的Heroku我已经得到每当试图触发设计发送电子邮件以下信息

Started POST "/members/forgot-password" for 127.0.0.1 at 2013-02-24 00:02:27 +1100

ArgumentError - wrong number of arguments (2 for 1):
  app/mailers/devise/mailer.rb:8:in `reset_password_instructions'

mailer.rb

    class Devise::Mailer < ::ActionMailer::Base
  include Devise::Mailers::Helpers

  def confirmation_instructions(record)
    devise_mail(record, :confirmation_instructions)
  end

  def reset_password_instructions(record)
    devise_mail(record, :reset_password_instructions)
  end

  def unlock_instructions(record)
    devise_mail(record, :unlock_instructions)
  end
end

Answer 1:

看来最新版本需要一个额外的参数。
至少它为我的代码。下面是我的自定义邮件类的工作代码。
请注意额外的参数action每种方法。

  class MyMailer < ActionMailer::Base

    include Devise::Mailers::Helpers

    def confirmation_instructions(record, token, opts={})
      @token = token
      devise_mail(record, :confirmation_instructions, opts)
    end

    def reset_password_instructions(record, token, opts={})
      @token = token
      devise_mail(record, :reset_password_instructions, opts)
    end

    def unlock_instructions(record, token, opts={})
      @token = token
      devise_mail(record, :unlock_instructions, opts)
    end

    # optional: this override method is from Devise::Mailers::Helpers
    def headers_for(action,opts={})
      …
    end

  end

Answer 2:

尝试这种方式，因为“设计在最近的版本中引入一个额外的参数选项”如上面提到的答案

     def reset_password_instructions(record, opts={})
       devise_mail(record, :reset_password_instructions)
     end

Answer 3:

这是由于设计在最近的版本中引入一个额外的参数选项。我想你想是这样的：

class Devise::Mailer < ::ActionMailer::Base
  include Devise::Mailers::Helpers

  def confirmation_instructions(record, opts={})
    devise_mail(record, :confirmation_instructions, opts={})
  end

  def reset_password_instructions(record)
    devise_mail(record, :reset_password_instructions, opts={})
  end

  def unlock_instructions(record)
    devise_mail(record, :unlock_instructions, opts={})
  end

  def headers_for(actions, opts={}

  end
