Find nearest cafe and airports of a given latitude rails

Question

I have latitude and longitude of an address and I want to search all the airports, Railway stations, Bus Stand and cafe etc popular places. I'm using these gems in my application :

gem 'geocoder'
gem 'gmaps4rails'
gem 'geokit-rails

Now Please suggest me how can I solve this problem?

Answer 1

We can pass the search parameters in type (these search strings are suggested by google for places)

    lat="30.987674"
    lng="-45.098753"   
    doc = JSON.parse(open("https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=#{lat},#{lng}&radius=50&type=['cafe']&name=cruise&key=xxxxxx").read)
    cords=[]
    doc['results'].each do |r|
      tmp={}
      tmp = r['geometry']['location']
      tmp["name"] = r['name']
      cords<< r['geometry']['location']
    end

Here cords is the array of hashes with relative information about places i.e. cafes.
