Question

之前我没有遇到过这种情况，但是自从将我的rails网站移到Heroku后，每当我试图触发Devise发送电子邮件时，我都收到以下消息

Started POST "/members/forgot-password" for 127.0.0.1 at 2013-02-24 00:02:27 +1100
Processing by Devise::PasswordsController#create as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"9G1P34ddbq2TN7SkmFuCet5d7fPMvWdSSpIaGqSZW9g=", "user"=>{"email"=>"paul.mcguane@*****"}, "commit"=>"Recover password"}
  User Load (3.1ms)  SELECT "users".* FROM "users" WHERE "users"."email" = 'paul.mcguane@me.com' LIMIT 1

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

似乎latest version需要额外的论据至少它适用于我的代码。这是我的自定义邮件程序类的工作代码请注意每个方法的额外参数action。

  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'设计在最新版本中引入了一个额外的选项参数'，如上面的回答所述

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

Answer 3

这是由于Devise在最新版本中引入了额外的选项参数。我想你想要的东西：

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={}
    # see http://stackoverflow.com/a/14698599/18706
  end

end
