Ruby on Rails Active Admin未定义的方法`除了＆＃39;对于＃<string：0x000000051298f0>
我有一个ruby网站设置，并且我的所有管理页面都有Active Admin。突然之间，一个管理类别页面产生了以下错误。该类别是数据库中关系的顶级。 我检查了列名引用的所有内容，确保正确定义了关系，并正确设置了数据库。我确信/app/admin/category.rb也没关系。在这一点上，我不确定这是否实际上是我的代码的问题，但宝石问题。任何正确方向的帮助将不胜感激！

2 个答案:
答案 0 :(得分：0)
好的，我想出来了！对于将来可能会遇到类似问题的其他人。
对于初学者，我的Category表用于生成网站的导航，因此我的应用程序控制器中有一个before_filter：
class ApplicationController < ActionController::Base
include NaviGenerator
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
before_filter :getCategories
private
def getCategories
@categories = categoryListGen 'nav'
end
end
我不确定为什么和我正在进一步挖掘，但是在Active Admin加载之前查询类别以生成导航的某些事情导致了某种类型的碰撞，我通过Better Errors gem和Caller的绑定发现了这一点宝石。这表明导航代码在Active Admin加载之前生成，从而导致错误。所以我通过这样做来修复它：
class ApplicationController < ActionController::Base
include NaviGenerator
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
before_filter :getCategories
private
def getCategories
cururl = request.original_url
cururl.to_s
if cururl.include? "admin"
##Dont run navi code!
else
@categories = categoryListGen 'nav'
end
end
end
我已经以不同的方式快速模拟了这一点，看起来如果你有一个运行并设置全局变量的before_filter并且你使用了主动管理员，它将导致在访问相关的Active Admin时所述方法使用的模型无法加载页。
我不确定这是否是一个错误，我将不得不挖掘更多来找出确切的原因。但是，当前正在对当前网址进行测试以查看它是否包含字符串admin时，使用Active Admin时，前端和后端至少都有幸福。
答案 1 :(得分：-1)
我认为您想要的是将config.skip_before_action :getCategories添加到您的ActiveAdmin initizializer
