Rails 上 Ruby 中的参数错误（参数数量错误）由于 Devise 和 PostageApp 的集成

Question

我是一个相对较新的 RoR 爱好开发者。我使用 Devise 进行用户管理，并计划使用 PostageApp 发送 "forget password" 电子邮件。 RoR 版本为 4.2.0。

我已正确配置 PostageApp。并按照 PostageApp 网站上的说明进行操作。但是，我一直收到 "wrong number of arguments" 错误。

Answer 1

当 reset_password_instructions 实际需要 3:

时，您只将一个必需的参数传递给 reset_password_instructions

reset_password_instructions(record, token, opts = {})

另外，看看 THIS post

Answer 2

当我们使用 devise 时，我们必须使用传递默认参数编写以下代码

app/models/user.rb

  handle_asynchronously :send_reset_password_instructions
  handle_asynchronously :send_confirmation_instructions
  handle_asynchronously :send_on_create_confirmation_instructions

使用延迟作业活动记录发送包含排队过程的 Devise 电子邮件 gem

#创建新用户后发送确认邮件

def send_on_create_confirmation_instructions
    Devise::Mailer.delay.confirmation_instructions(self, :confirmation_instructions, opts={})
  end

#发送重置密码邮件

def send_reset_password_instructions
    Devise::Mailer.delay.reset_password_instructions(self, :reset_password_instructions, opts={})
  end

#发送解锁邮件

def send_unlock_instructions
    Devise::Mailer.delay.unlock_instructions(self, :unlock_instructions, opts={})
  end
