使用 Geocoder 进行 Mongoid 查询
我一直在浏览 mongoid 文档、Geocoder 文档，并询问了一位朋友，但我仍然对此有些困惑。我有两个模型，Event 和 Place：
class Event
include Mongoid::Document
belongs_to :place
end
class Place
include Mongoid::Document
has_many :events
end
我已经设置了它们，以便 Event.place 和 Place.events 正常工作，但让我困惑的是将地理编码器附近方法合并到查询中。目前 Place.near(location) 工作正常，我想做的是按位置查询事件，所以 Event.place.near(location)
我已经尝试查看以下内容：
@events = Event.where('event.place' => close(location)
@events = Event.where(place.near(location))< /code>
任何帮助将不胜感激。
I've been going through the mongoid docs, Geocoder docs and have asked a friend, but am still a little stuck on this. I've got two Models, Event and Place:
class Event
include Mongoid::Document
belongs_to :place
end
class Place
include Mongoid::Document
has_many :events
end
I've set these up so that Event.place and Place.events work fine, the thing that is throwing me is incorporating the Geocoder near method into queries. Currently Place.near(location) works fine, what I'm wanting to do is query Events by their location, so Event.place.near(location)
I've tried looking at things like:
@events = Event.where('event.place' => near(location)
@events = Event.where(place.near(location))
Any help would be appreciated.

这不是吗
？您可以查询类似的事件
Wouldn't this to be
and you can query the events like
