Getting Started with Apache Cassandra and the DS Ruby Driver

getting_started.rb

require 'cassandra'
 
cluster = Cassandra.connect
#cluster.each_host do |host|
# puts "Host #{"127.0.0.1"}: id=#{"6123e2c1-e3ca-4d08-a544-1315b2f399f1"} datacenter=#{"datacenter1"} rack=#{"rack1"}"
#end
 
keyspace = 'demo'
session = cluster.connect(keyspace)
 
session.execute("INSERT INTO users (lastname, age, city, email, firstname) VALUES ('Jones', 35, 'Austin', 'bob@example.com', 'Bob')")
 
session.execute("SELECT firstname, age FROM users WHERE lastname='Jones'").each do |row|
  p "Firstname = #{row['firstname']}, Lastname = #{row['lastname']}, Age = #{row['age']}"
end
 
 
 
session.execute("UPDATE users SET age = 36 WHERE lastname = 'Jones'")
 
session.execute("SELECT firstname, age FROM users WHERE lastname='Jones'").each do |row|
  p "Firstname = #{row['firstname']}, Lastname = #{row['lastname']}, Age = #{row['age']}"
end
 
 
 
session.execute("DELETE FROM users WHERE lastname = 'Jones'")
 
session.execute("SELECT * FROM users").each do |row|
  p "Firstname = #{row['firstname']}, Lastname = #{row['lastname']}, Age = #{row['age']}"
end

cluster = Cassandra.connect

returns :
getting_started.rb:3:in <top (required)>': undefined methodconnect' for Cassandra:Module (NoMethodError)
from -e:1:in load' from -e:1:in

'

Looks like it should be changed to Cassandra.cluster
