Assignment 3 for COMP 120 @ Tufts

Geolocation and National Historic Places

link to actual assignment

I wrote two models and a helper class.

  1. HistoricPlace objects store all the CSV parsed places
  2. DistanceHelper class in lib/distance_helper.rb helps to generate SQL to search for placed near a give location.
  3. Google API Key is defined separately in production.rb and development.rb so that I can develop with a localhost dev license and use a production license too.
  4. I overwrite the HistoricPlace.calc method to display distances with 2 decimal places
  5. Store all locations queried from and update their query_count (and time stamp) if multiple queries from one location.
  6. Uses JQTouch for mobile version.
  7. Use index to test browser type and render m.html if mobile otherwise I run another method.
  8. I have a library file to be used to load the csv file. It need the Rails environment so call it with script/runner.

To parse the data file run

ruby ./script/runner ./lib/ne_parser.rb csv-file.csv
