我通过多吗?
belongs_to :addressable, :polymorphic => true
以及我的资源,请说它是一个酒店。
has_one :address, :as => :addressable
我可以检索我的地址数据,看不出问题,在我的搜索镜的20英里半径中找到每个地址。
@addresses = Address.near(params[:search],20, :order => :distance).page params[:page]
我确实在努力加入资源,即旅馆信息,但我可以链接到一个详细页,但我要以我的成果为例说明旅馆的名称。
我设想使用:因此可以帮助:
@addresses = Address.near(params[:search],20, :order => :distance, :include => :hotel).page params[:page]
.. but no luck
任何建议都得到高度赞赏。

在一位同事的帮助下,我看到了这一说法。
@addresses = Address.where(addressable_type: Hotel ).near(params[:search],20, :order => :distance).includes(:addressable).page params[:page]
希望能帮助别人!
在您的讲话模式中,我将界定与酒店模式的关系。
belongs_to :addressable, :polymorphic => true
belongs_to :hotel, -> { where(adresses: {addressable_type: Hotel }) }, foreign_key: addressable_id
同本答复中充分解释的一样,
