Geolocation google api on a ruby on rails Site

Question

I have a process on my ruby site that should pull geographical data and insert it into my locations table.

I did not program this. It was with the site when our company took over. I dont know alot about ruby or JSON/XML

  def self.check_unknown(cs)
    report = Report.first( :conditions => { :metric => "unknown_locations", :name => cs } )
    #i.e. if it's been tried 25 times, add it to the locations table.
    if report.value > 5
      city, state = cs.split(",")
      state = state.strip
      google_api_results = HTTParty.get("http://maps.googleapis.com/maps/api/geocode/json?address=#{cs.gsub(/ /, "%20")}&sensor=true")
      geo_data = google_api_results.parsed_response
      lat = geo_data["results"][0]["geometry"]["location"]["lat"]
      lng =  geo_data["results"][0]["geometry"]["location"]["lng"]
      l = Location.new({ 
        :city => city,
        :state => state,
        :coords => "ST_GeographyFromText('POINT( #{lat} #{lng} )')"
      })
      l.save
      Report.delete(report.id)
      return l
    else
      return false
    end
  end

This is using the following table for information:

ID     NAME                        METRIC               VALUE    CREATED_AT                       UPDATED_AT

Expose to insert data into locations table like:

Answer 1

Your database columns are called CORDS but in the hash you pass to Location.new, you pass the key :coords. You also fail to pass a :zip.

Does the Location model define a different mapping?
