ruby-on-rails – 使用SendGrid模板的Rails Mailer

如何使用smtpapi- ruby gem将我的rails邮件绑定到Sendgrid？我已经关注了他们的 limited documentation,但我的电子邮件没有通过,我已经验证了我的SendGrid实现在发送普通电子邮件时工作正常,所以不是这样.这就是我所拥有的：

user_controller.rb

def create
    @user = User.new(user_params)

    respond_to do |format|
      if @user.save
        format.html { redirect_to @user,notice: 'User was successfully created.' }
        format.json { render :show,status: :created,location: @user }


        header = Smtpapi::Header.new
        header.add_to(@user.email)
        header.add_substitution('user',[@user.name])
        header.add_substitution('body',"You've registered! This is from the controller.")
        header.add_filter('templates','enable',1)
        header.add_filter('templates','template_id','xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx')
        header.to_json

        UserNotifier.welcome(header).deliver
      else
        format.html { render :new }
        format.json { render json: @user.errors,status: :unprocessable_entity }
      end
    end
  end

邮寄/ user_notifier.rb

class UserNotifier < ApplicationMailer
  default from: "test@test.com"

  def welcome(header)
    headers['X-SMTPAPI'] = hdr.to_json
    mail(subject: "Welcome to the site!")
  end
end

视图/ user_notifier / welcome.html.erb

<html>
 <body>
   Hi -user-<br />
   Thanks so much for joining us!

   <p>-body-</p>

   Thanks,<br />
   The Microblog Team
 </body>
</html>

我在SendGrid活动日志中没有看到任何内容,所以它甚至没有被发送到那里,至少我的猜测是这样.

我究竟做错了什么？

解决方法

我认为你混淆了你的变量.你调用hdr.to_json,param名称是header,它也已经转换为json.

您应该将标头元数据直接包含在UserNotifier中：

headers "X-SMTPAPI" => {
    "sub": {
      "%name%" => [user.name]
    },"filters": {
      "templates": {
        "settings": {
          "enable": 1,"template_id": 'xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx'
        }
      }
    }
  }.to_json

# the 'to' email can be overridden per action
mail(
  from: 'test@test.com',to: 'recipient@test.com',subject: "Hello World"
)

如果UserNotifier.welcome用于应用的其他部分,您也可以传递内容：

UserNotifier.welcome(user: @user,subject: "Welcome!").deliver_now

# user_notifier.rb

class UserNotifier < ApplicationMailer
  default from: "test@test.com"

  def welcome(user:,subject:,template: "default" )

    # template's default view is "default"
    headers "X-SMTPAPI" => {
     "sub": {
       "%name%" => [user.name]
     },"filters": {
       "templates": {
         "settings": {
           "enable": 1,"template_id": 'xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx'
         }
       }
     }
    }.to_json

    mail(
      from: 'test@test.com',to: user.email,subject: subject,template_path: 'path/to/view',template_name: template
    )
    # this would try to render the view: `path/to/view/default.erb`
  end
end

在模板中,您可以通过添加标记的名称来包含替换标记：

<h1>Hello %name%!</h1>
