在设计电子邮件主题中添加动态值

Question

好的,我已经看到很多关于自定义设计电子邮件主题的讨论,但似乎没有解决我想要的问题.目前,我的确认电子邮件主题为" 确认您的Qitch.com帐户 ".我想自定义此电子邮件主题并在其中添加用户名称的动态值,以便在用户ALEX注册帐户时,他应该获得主题为Welcome ALEX的电子邮件地址,确认您的Qitch.com帐户.我怎样才能在设计中实现这一目标？

devise.en.yml

mailer:
  confirmation_instructions:
    subject: 'Confirm your Qitch.com account'
  reset_password_instructions:
    subject: 'Reset your Qitch.com password'
  unlock_instructions:
    subject: 'Unlock your Qitch.com account'

最后,如何在回复地址或地址中添加名称,目前当您收到邮件时,它说发件人:no-reply@qitch.com有没有办法我可以自定义它Qitch

谢谢

Answer 1

我看到答案都不够干净,所以我想在这里做一个简短的总结.

1. 首先,您必须告诉Devise您将通过以下方式覆盖其原始邮件程序方法:

配置/初始化/ devise.rb

config.mailer = 'MyOverriddenMailer'

2. 之后,您需要创建重写的邮件程序类并覆盖您想要的任何方法,如下所示:

应用程序/邮寄者/ my_overridden_​​mailer.rb

class MyOverriddenMailer < Devise::Mailer
  helper :application # gives access to all helpers defined within `application_helper`.
  include Devise::Controllers::UrlHelpers # Optional. eg. `confirmation_url`
  default template_path: 'devise/mailer' # to make sure that you mailer uses the devise views

  def confirmation_instructions(record, token, opts={})
    if record.name.present?
      opts[:subject] = "Welcome #{record.name}, confirm your Qitch.com account"
    else
      opts[:subject] = "Confirm your Qitch.com account"
    end

    super
  end

end

3. 请记住重新启动Rails服务器以应用更改!:)

注意:

• opts选项列表:subject,to,from,reply_to,template_path,template_name.
• record是User模型的实例
• 当然还有原始文件

在这里设计助手以及如何:使用自定义邮件程序

class MyMailer < Devise::Mailer


   def confirmation_instructions(record, opts={})
    headers = {
        :subject => "Welcome  #{resource.name}, confirm your Qitch.com account"
    }
    super
  end

  def reset_password_instructions(record, opts={})
    headers = {
        :subject => "Welcome  #{resource.name}, reset your Qitch.com password"
    }
    super
  end

  def unlock_instructions(record, opts={})
    headers = {
        :subject => "Welcome  #{resource.name}, unlock your Qitch.com account"
    }
    super
  end

end

要么

class MyMailer < Devise::Mailer
...
...
private

 def headers_for(action)
  if action == :confirmation_instructions
    headers = {
      :subject => "Welcome  #{resource.name}, confirm your Qitch.com account"
    }
  elsif action == :reset_password_instructions
    headers = {
      :subject => "Welcome  #{resource.name}, reset your Qitch.com password"
    }
  else
    headers = {
      :subject => "Welcome  #{resource.name}, unlock your Qitch.com account"
        }
  end
 end
end

并告诉设计使用您的邮件:

#config/initializers/devise.rb
config.mailer = "MyMailer"
