• batchinsert mode ruby based index provider
• support for batchinsert mode! just open the database with Cadet::BatchInserter::Session.open() instead of Cadet::Session.open()! this no-ops transaction, simply yielding to the supplied block.

super simple. you dont even need to download neo4j.

1. Gemfile

   gem 'cadet'
   

2. bundle install

3. cadet-example.rb

   
   require 'cadet'
   require 'yaml'
   
   data = YAML.load_file('legislators-current.yaml')
   
   #open the database, db is now used to interact with the database
   db = Cadet::Session.open("neo4j-community-2.0.0/data/graph.db")
   
   db.transaction do
     ["Legislator", "Party", "Gender", "State"].each {|v| db.constraint v, "name"}
   end
   
   data.each do |leg|
     #begin a transaction. the transaction will automatically finish at the end of the provided block
     db.transaction do
   
       #get_a_X_by_y(value) will get or create a node labeled 'X', with a property 'y' of value 'value'
       l = db.get_a_Legislator_by_name leg["name"]["official_full"]
       p = db.get_a_Party_by_name      leg["terms"].first["party"]
       g = db.get_a_Gender_by_name     leg["bio"]["gender"]
       s = db.get_a_State_by_name      leg["terms"].first["state"]
   
       l.outgoing(:party)      << p
       l.outgoing(:gender)     << g
       l.outgoing(:represents) << s
     end
   end
   
   #close the database
   db.close()
   
   

4. bundle exec ruby
