Én használ Geocoder . Azt akarom, hogy közel helyeken, de ez visszatérő üres tömböt.

Van ez az adatbázisban:

id: 5,
name: sogra2,
lat: -22.833575,
long: -43.312882,

Ez az én akció a közeli coordenates

def near
  @near = Test.near([-22.844279, -43.306174], 100, :units => :km)
  render json: @near
end

Ez az én modell:

class Test < ApplicationRecord
  reverse_geocoded_by :lat, :long
end
