Question

当导航到我的大学/新页面时，HTTP正如我所期望的那样工作。这是用于生成表单的服务器输出。

enter image description here

现在当我填写数据并选择f.submit时，我的日志显示Rails正在启动GET。

enter image description here

当我尝试编辑现有资源时，会发生同样的事情。这是提取资源的正确GET请求。

enter image description here

当我选择更新按钮而不是PUT时，我的日志看起来像这样。 enter image description here

我已经阅读了一些密切相关的SO问题，并意识到当我尝试将供应商资产添加到应用程序时，我的问题就开始了。我还没有让Bower正常工作，并且未能使用Rails指南正确实现我的网站模板，所以也许这就是事情出乎意料的原因。我希望找到与请求一起发送的正确HTTP动词的解决方案。而且我希望能更好地理解我是否可以在另一个范围内解决与凉亭或资产管道相关的.js模板问题。或者是我的外部模板文件的添加导致Rails混合了一些东西。

感谢您的帮助。

以下是我的其他相关文件。
