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，但似乎没有一个能解决我想要的问题。目前我的确认邮件主题为“Confirm your Qitch.com account”。我想自定义这个电子邮件主题并在其中添加用户名的动态值，这样如果用户 ALEX 注册了一个帐户，他应该得到一个主题为 Welcome 的电子邮件地址ALEX，确认您的 Qitch.com 帐户。我怎样才能在设计中实现这一点？

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，我如何在回复地址或发件人地址中添加姓名，目前当您收到邮件时，它说发件人：no-reply@qitch.com 有没有办法可以将其自定义为Qitch

谢谢

Answer 1

将headers_for 连接到例如为所有设计邮件的主题添加前缀。

# config/initializers/devise.rb

Devise.setup do |config|
  # ...
  config.mailer = 'DeviseMailer'
  # ...
end

# app/mailers/devise_mailer.rb

class DeviseMailer < Devise::Mailer
  def headers_for(action, opts)
    super.merge!({ subject: 'Hi ALEX! ' + subject_for(action) })
  end
end

Answer 2

我发现没有足够清晰的答案，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方法：

config/initializers/devise.rb

config.mailer = 'MyOverriddenMailer'

1. 之后，您需要创建重写的邮件程序类并重写您想要的任何方法，如下所示：

app/mailers/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

1. 记得重新启动 Rails 服务器以应用更改！ :)

注意：

• opts 选项列表：主题、收件人、发件人、回复收件人、模板路径、模板名称。
• record 是 User 模型的实例
• 当然还有origin document

我正在使用 devise (3.2.1) 并且我已经实现了以下解决方案，但是要使用本地化修改 from: 字段：

# app/mailers/devise_mailer.rb
class DeviseMailer < Devise::Mailer

  def confirmation_instructions(record, token, opts={})
    custom_options(opts)
    super
  end

  def reset_password_instructions(record, token, opts={})
    custom_options(opts)
    super
  end

  def unlock_instructions(record, token, opts={})
    custom_options(opts)
    super
  end

  private

  def custom_options(opts)
    opts[:from] = I18n.t('devise.mailer.from', name: Tenancy.current_tenancy.name, mail: ENV['FROM_MAILER'] )
  end
end

然后我在我的语言环境文件中定义了消息

# config/locales/devise.es.yml
es:
  devise:
    mailer:
      from: "Portal de trabajo %{name} <%{mail}>"

修改主题，应该差不多：

  def confirmation_instructions(record, token, opts={})
    custom_options(opts, :confirmation_instructions)
    super
  end

  private

  def custom_options(opts, key)
    opts[:from] = I18n.t('subject', scope: [:devise, :mailer, key])
  end

# and in your locale file
es:
  devise:
    mailer:
      confirmation_instructions:
        subject: Instrucciones de confirmación

Answer 4

你应该创建一个像这样的 ActionMailer：

class Sender < ActionMailer::Base
   default :from => "'Eventer' <dfghjk@gmail.com>"

   def send_recover(user, pw)
      mail(:to => user.email , :subject => "You have requested to change your password from Eventer") do |format|
             format.text { 
             render :text =>"Dear #{user.name}, 

                             **Body**

                             Regards."
            }
      end
   end
end

那么你应该这样从控制器调用它：

Sender.send_recover(@mail, current_user, @meetup).deliver

我希望它对你有用！

设计助手here 和How To: Use custom mailer

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

或者

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

并告诉设计使用你的邮件：

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