如何显示与惨惨在Rails3中活动页面上存取遭拒错误 [英] How to show AccessDenied errors on the active page with CanCan in Rails3

问题描述

我试图找到一种方法，在活动页面上显示我的闪存错误，而不 redirect_to的方法。

顺便说一句，标准的闪存[：警惕] = exception.message 并没有给我任何错误信息，所以我改成了闪光灯[：错误]

感谢您的任何意见！

  rescue_from惨惨::存取遭拒办|例外|
    闪光[：错误] = exception.message
    redirect_to的deadlines_path
结束
 

解决方案

尝试：

  rescue_from惨惨::存取遭拒办|例外|
  flash.now [：警惕] = exception.message
  渲染something_else
  返回false
结束
 

不重定向。

I am trying to find a way to display my flash errors on the active page without the redirect_to method.

By the way, the standard flash[:alert] = exception.message didn't show me any error messages, so I changed it to flash[:error].

Thanks for any advice!

rescue_from CanCan::AccessDenied do |exception|  
    flash[:error] = exception.message  
    redirect_to deadlines_path  
end

解决方案

Try:

rescue_from CanCan::AccessDenied do |exception|
  flash.now[:alert] = exception.message
  render 'something_else'
  return false
end

without a redirect.
