Question

我让Mandrill设置为在Heroku上发送SMTP电子邮件。我的应用程序是rails应用程序。当用户注册时，它会按预期发送电子邮件。但是，我还设置了一个“邀请”操作，允许用户通过电子邮件邀请其他用户。这不会被发送，虽然日志表明它是，并没有抛出错误。我有：

config.action_mailer.raise_delivery_errors = true

以下是相关日志：

似乎邮件是在user_mailer呈现之前发送的，但我不知道为什么。我这样做了：

1）表单将您在上面看到的参数发送到控制器中的协作操作。 2）此操作如下所示：

def collaborate
  @user = params[:user]
  @title = params[:title]
  @course = params[:course]
  @email = params[:email]
  @key = params[:key]
  UserMailer.collaborate(@user, @title, @course, @email, @key).deliver

  redirect_to course_path(@course), notice: 'Invitation sent!'
end

3）UserMailer.collaborate看起来像这样：

def collaborate(user, title, course, email, key)
  @user = user
  @title = title
  @course = course
  @email = email
  @key = key
  mail from: @user, to: @email, subject: "Please join me creating a course!"
end

4）collaborate.text.erb只是一条使用我设置的实例变量的消息。

解决方案是表单自动生成：put而不是a：get请求。出于某种原因，这不是本地服务器上的问题，而是推迟到生产，这阻止了邮件被发送出去。关键是使用：get请求覆盖默认的form_tag：put请求。

使用Heroku上的mandrill在rails 3.2中发送邮件
