Error when trying to find a node #24

Closed chintanparikh closed 11 years ago

chintanparikh commented 11 years ago

Code:

desc "Generate the Neo4j database of counties"
task :generate_adjacent_counties_database do
  file = File.open('db/adjacent_counties.txt')

  data = file.read.force_encoding("iso-8859-1").split("\n\n\n")

  data.each do |string|
    parent_node = nil
    string.each_line do |line|
      county = line.scan(/\[\[(.*), (.*)\]\]/)
      parent_node = Neography::Node.find("counties", "name", county[0][0])
      if parent_node.nil?
        parent_node = Neography::Node.create("name" => county[0][0], "state" => county[0][1])
      end
    end
  end
end

I'm trying to create a rake task to generate a database based on a text file, here's the error I'm getting:
