我已经在我的路线中给出了这个。
get '/custom_page/:page_name' => 'custom_page#load_content'
当我点击一个带有url的菜单时说'/ custom_page / abc'它工作正常..它转到控制器以及名为load_content的视图。但问题是终端中的应用程序崩溃。虽然它没有在前端显示.. 我在终端上收到这些错误消息..猜猜..？

似乎首先呈现正确的页面（由CustomPageController处理#load_content为HTML），然后它将处理为PNG。 （由CustomPageController处理#load_content as PNG） 我的控制器
class CustomPageController < ActionController::Base
layout 'calculator'
def load_content
page_name = (params[:page_name]).split("_").join(" ")
session[:tab] = page_name
@menu_item = MenuItem.where(url: "/custom_page/"+params[:page_name])
if @menu_item.first.custom_page.present?
@description = @menu_item.first.custom_page.description
else
@description = "CUSTOM PAGE NOT FOUND..."
end
end
end
