从来没有呈现布局响应xhrs [英] Never render a layout in response to xhrs

问题描述

在大多数情况下，我不希望呈现一个布局时，请求来自AJAX。为此我一直在写渲染：布局=＆GT; ！request.xhr？经常在我的控制器动作。

Most of the time I don't want to render a layout when the request comes from AJAX. To this end I've been writing render :layout => !request.xhr? frequently in my controller actions.

我怎样才能使这个的默认的？即，我希望能够写

How can I make this the default? I.e., I'd like to be able to write

def new
  Post.find(params[:id])
end

和具备的功能是

def show
  Post.find(params[:id])
  render :layout => !request.xhr?
end

（我没事手动指定在其中我想用一个罕见的情况下的布局。）

(I'm fine manually specifying a layout in the rare cases in which I want to use one.)

推荐答案

这个怎么样？

class UsersController < ApplicationController
  layout proc {|controller| controller.request.xhr? ? false: "application" }
end
