This gem lets you easily interact with Google Fusion Tables API from your Ruby application via a plain SQL interface, or an object orientated interface.

upgrading to current (v0.4.x)

Thanks to DerekEder's work, v0.4 supports the new Fusion Tables JSON API rather than the now defunct CSV API. This has introduced some small (but possibly breaking) changes:

  1. Geometry is returned as GeoJSON rather than KML.
  2. Null values are returned as empty strings (the FT API does this, so we're a bit stuck here).
  3. You need to supply an api_key to use the service. You can get an API key from your Google API console.

See the example below and tests for more.

Demo and examples

Installation

gem install fusion_tables

Gem Dependencies

  • gdata_19 >= 1.1.2

Rubies

  • 1.8.7
  • 1.9.2

Usage

require 'fusion_tables'
	
	
# Connect to service	
@ft = GData::Client::FusionTables.new      
@ft.clientlogin(username, password) 
@ft.set_api_key(api_key) # obtained from the google api console


# 1. SQL interface
# =========================
@ft.execute "SHOW TABLES" 
@ft.execute "INSERT INTO #{my_table_id} (name, geo) VALUES ('tokyo', '35.6894 139.6917');"
@ft.execute "SELECT count() FROM #{my_table_id};"


# 2. ORM interface
# ========================
# Browse existing tables
@ft.show_tables
 # => [table_1, table_2] 

# Getting table id suitable for using with google maps (see more below)
table_1.id #=> 42342 (the table's google id)

# Count data
table_1.count #=> 1

# Select data
table_1.select 
 #=> data

# Select data with conditions
table_1.select "name", "WHERE x=n"
 #=> data

# Select ROWIDs
row_ids = table_1.select "ROWID"

# Drop tables
@ft.drop table_1.id                    # table id
@ft.drop [table_1.id, table_2.id]     # arrays of table ids
@ft.drop /yacht/                      # regex on table name

# Creating a table
cols = [{:name => "friend name",    :type => 'string' },
        {:name => "age",            :type => 'number' },
        {:name => "meeting time",   :type => 'datetime' },
        {:name => "where",          :type => 'location' }]

new_table = @ft.create_table "My upcoming meetings", cols

# Inserting rows (auto chunks every 500)
data = [{"friend name" 	=> "Eric Wimp", 
         "age"          => 25, 
         "meeting time" => Time.utc(2010,"aug",10,20,15,1),
         "where"        => "29 Acacia Road, Nuttytown"}]
new_table.insert data

# Currently FT API only supports single row UPDATE.
new_table.update 1, [{"friend name"	=> "Bananaman"}]

# Delete row
new_table.delete 1

# Delete all rows
new_table.truncate!

Known Issues

  • The Google gdata_19 gem conflicts with the GData2 gem. Only current fix is to uninstall GData2.
  • You have to make a table public before you can display it on a map. This can only be done via FT web interface.

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request.
