I'm working on a task that calculate the distance between two gps points and I want to convert the distance to KM :
def distances
site = Site.find params[ :id ]
stores = Store.current
distances =
stores.map do |store|
distance = Haversine.distance(site.address.latitude, site.address.longitude, store.address.latitude, store.address.longitude)
distances <<
name: store.name,
value: distance
end
render json:
distances: distances.to_json
end
example of calculated item :
store2 : 5527.654499076738
in the doc of haversine gem there is a method to convert : distance.to_kilometers but it doesn't work for me ! any help ?

in which unit you're are getting the distance right now?

it's Haversine::Distance unit

how is it not working for you? What's it doing instead? Can you show how you tried calling it?

hi @SimpleLime : like that : distance = Haversine.distance(site.address.latitude, site.address.longitude, store.address.latitude, store.address.longitude).to_kilometers

the distance variable should be Haversine::Distance as class type , but when checked it it's on Float < Numeric !

You probably need to call the to_kilometers method on the resulting Haversine::Distance otherwise its to_s method will be used:
def distances
site = Site.find params[ :id ]
distances = Store.current.map do |store|
name: store.name,
value: Haversine.distance(
site.address.latitude,
site.address.longitude,
store.address.latitude,
store.address.longitude
).to_kilometers
end
render json:
distances: distances
end
What you'll really want to do though is add a distance_in_km to your Address class...
