Ruby on rails ActionController:：创建方法中的未知信息格式

我在试着使用“设计宝石”。我尝试在未登录的情况下创建帐户。模型控制器向我返回以下错误：

我不明白。是什么导致了这个错误？我在github上的项目是

url是

成员。成员

，rails将

'.members'

作为扩展名，如.json或.xml，这就是为什么会出现此错误。

此错误显示是因为您没有以json或html形式请求url。请检查控制台，了解它以何种格式命中url。

在此处提问时，请将错误文本与代码内容（请阅读此帮助条目：）一起包括在内，而不仅仅是链接。这不仅有助于人们回答你的问题，而且有助于将来任何人在链接失效的情况下查看你的问题。好的，很抱歉。谢谢你的解释！我应该换什么？表格？URL是“member.members”而不是“members.member”？您如何创建指向该路由的链接？有一个控制器指向注册设备（即未登录）。控制器为“注册”。我将在主题上发布它。表单包含一个URL并指向URL:members_path（resource_name）（路由中是members#create）*EDITEDLooks这个问题发生在其他人身上，就像我之前告诉过你的那样，“.members”是个问题，我不确定Deave为什么要创建它，你可以在链接中找到几种方法来处理这个问题，我希望这能帮助你。我检查了控制台。它尝试提交DB，但返回以下内容：Started POST“/members.member”在2016年2月21日15:50:21-0300由MembersController处理，创建为，操作中的错误ActionController:：UnknownFormat（ActionController:：UnknownFormat）：app/controllers/members\u controller.rb:28:in“create”抱歉，我是初学者。
