Ruby on rails ROR中的嵌套属性
我正在尝试创建一个应用程序,用户可以在其中自由创建店铺,并且在调用show操作时显示特定店铺的关联店铺项目,但我似乎做错了什么。这里的任何帮助都将不胜感激。我在下面附上了我代码的截图Ruby on rails ROR中的嵌套属性,ruby-on-rails,Ruby On Rails,我正在尝试创建一个应用程序,用户可以在其中自由创建店铺,并且在调用show操作时显示特定店铺的关联店铺项目,但我似乎做错了什么。这里的任何帮助都将不胜感激。我在下面附上了我代码的截图 class ShopItem < ActiveRecord::Base belongs_to :shop def self.find_shop_items_for_sale find(:all, :order => "title", :conditions

如果指定商店:有很多:商店物品
,则不必指定像查找商店物品以供出售之类的操作
。只要打电话:
@shop = Shop.find(params[:id])
@shop_items = @shop.shop_items
另外,尝试为用户检索所有商店商品(操作user
)也是一个坏主意。相反,看看宝石吧
另一方面,你的问题根本不是问题,如果你问一个特定的问题,或者只是试着解释一下你有什么问题,那就容易多了。请将代码块分成有意义的块。有很多东西要读。请解释一下为什么你认为自己“做错了”你有错误吗?是不是有些特定的事情没有按你预期的方式发生?@Ryan.我对大量的代码感到抱歉。我的错!我这里的问题是,当我试图显示一个特定商店的商品目录时,我得到一个未知的操作错误。我最初以为这是我的路线,但不确定@klew…我会试试你的建议。如果你遇到这样的错误,那就是路线问题。请回答您的路线问题。@klew..谢谢,问题是我的路线。将其更改为:-map.resources:shop\u items map.resources:shops,:has\u many=>[:shop\u items],并且一切似乎都正常工作。非常感谢。
