Griddler问题：参数数量错误（1表示0）

时间：2014-08-01 10:31:38

标签： ruby-on-rails ruby-on-rails-4 mailgun griddler

我正在尝试在我的Rails 4应用程序中使用Griddler。处理器似乎正在接收电子邮件（通过mailgun），但Griddler没有保存它。我在Griddler :: EmailsController中创建了一个特殊错误 ArgumentError的500错误#create 错误的参数数量（1表示0）。

这是我的处理器代码：

class EmailProcessor
  def self.process(email)
     Post.create!({ body: email.body, email: email.from })
  end
end

直接来自http://sendgrid.com/blog/receiving-email-in-your-rails-app-with-griddler/的教程。

我正在使用griddler（1.0.0）和griddler-mailgun（1.0.1）。

对于我为何会收到此错误的任何想法都将非常感谢！

跟踪（我认为......对此仍然是新手！）：

我刚刚遇到了同样的问题，但是当我发现最近Griddler被更新时，Mandrill解决了这个问题。

您的EmailProcessor代码需要更新为以下内容：

    class EmailProcessor

      def initialize(email)
        @email = email
      end

      def process
        Post.create!({ body: @email.body, email: @email.from })
      end

    end

当我在Griddler GitHub页面上重新阅读Configuration Options时，我发现了这一点。
