如何在Rails中的JSON / XML请求过滤器之前跳过 [英] How to skip before filters for json/xml requests in rails

问题描述

我找到了一种基于格式跳过过滤器的方法，如下所示，但是我想知道是否有更好的方法，因为这会使事情变得混乱并且不是很干燥。

I found a way to skip before filters based on the format, as seen below, but I'm wondering if there is a better way since this clutters things and isn't very DRY.

before_filter do |controller|
  :current_cart unless controller.request.format.js?
end

如果我不这样做，则由于current_cart方法而导致json请求失败，

If I don't do this, json requests fail because the current_cart method, and other methods, do things only meant for html.

推荐答案

您可以这样做：

before_filter :current_cart, :unless => :format_js?

def format_js?
  request.format.js?
end

希望这会有所帮助。
