Question

尝试使用ajax响应进行POST时，我收到了一个ActionviewTemplate错误。 'create'方法一直在寻找默认的create.js.erb文件，但我特意指出了它应该呈现的文件。

我尝试将“结束并返回”添加到我的respond_to块，但没有任何反应。

Answer 1

您的params支票不正确; liked_id嵌套在:appreciation哈希。

中

Answer 2

liked_id不在最高级别的参数中，它嵌套在params[:appreciation]中。您可以在find中的正确位置查找，但在if; elsif逻辑中，您正在寻找params[:liked_id]。

那里不存在，所以没有任何条件在运行。该操作结束时没有任何关于渲染内容的指令，因此默认发生。

Rails 3：无法弄清楚这个Actionview Template错误，需要帮助吗？
