data data data

Let's use location data, display them and search trought them !

You can set proxys and caching here

rails generate geocoder:config

Bulk update

rake geocode:all CLASS=Transaction SLEEP=0.25 BATCH=100

Neat example: reverse geocoding to get location of phone

reverse_geocoded_by :latitude, :longitude do |obj,results|
  if geo = results.first
    obj.city    = geo.city
    obj.zipcode = geo.postal_code
    obj.country = geo.country_code
  end
end
after_validation :reverse_geoc

Get within a box

sw_corner = [40.71, 100.23]
ne_corner = [36.12, 88.65]
Venue.within_bounding_box(sw_corner, ne_corner)

we used searchkick to quey into our elastic search instance: (don't forget to increase ram for docker in mac)

docker-compose up

to index:

Model.reindex
# and it does the work

searchkick really does more than a simple client for elastic search, it makes query easy.
