如何在Rails3中使用CanCan在活动页面上显示AccessDenied错误

Question

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

Try:

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

without a redirect.
