[英]Geocoder: How get all results and order by distance?
I know how to use the near
method to get all results within a certain radius, but how do I get all results and order by distance? 我知道如何使用
near
方法在一定范围内获得所有结果,但是如何获得所有结果并按距离排序?
I know I could do something like this: 我知道我可以这样做:
Location.near(my_location, 999999, order: 'distance')
However, I would rather skip the radius check altogether and simply get all results sorted by distance. 但是,我宁愿完全跳过半径检查,只需按距离排序所有结果。
I have had the same issue, and I ended up adding this scope to my geocoded class: 我遇到了同样的问题,最后我将这个范围添加到我的地理编码类:
class A
extend Geocoder::Model::ActiveRecord
reverse_geocoded_by :latitude, :longitude
scope :with_distance_to, ->(point) { select("#{table_name}.*").select("(#{distance_from_sql(point)}) as distance") }
end
This will allow you to do A.with_distance_to(point).order('distance')
这将允许你做
A.with_distance_to(point).order('distance')
