Question

我正在尝试通过Sinatra应用程序的POST方法将用户添加到数据库。我的数据库连接正常 - 我可以使用User.all.to_json获取。但是，当我尝试POST时，我收到一个非描述服务器错误，说我的请求失败了。据我所知，它与user.save电话有关。我做错了什么？

  post '/users/?' do
    @request_payload = JSON.parse request.body.read

    user = User.new(name: @request_payload["name"],
                    email: @request_payload["email"],
                    created_at: @request_payload["created_at"],
                    last_sign_in_at: @request_payload["last_sign_in_at"])

    user.save
  end

编辑：不确定它是否相关，但这是我连接到的数据库的架构：

Table "public.users"
         Column         |            Type             |                     Modifiers                      
------------------------+-----------------------------+----------------------------------------------------

快速选择： DataMapper（看起来你正在使用DataMapper）现在支持raise_on_save_failure;你可以把它当作 user.raise_on_save_failure 在你的保存电话之前，控制台应该显示出各种各样的爆发力。

如果save返回false，您可以转储user.errors.full_messages。有关这方面的更多信息，请点击此处。

我担心你没有将值传递给具有唯一索引的可空列（重置标记列）。

Model.save失败了吗？
