https://github.com/maxdemarzi/neography/blob/master/examples/traversal_example2.rb Interesting bit: def graduated_with_me(student) student = student["self"].split('/').last student_attended = @neo.get_node_relationships(student)[0] graduated = student_attended["data"]["graduated"] school = student_attended["end"].split('/').last @neo.traverse(school,"nodes", {"order" => "breadth first", "uniqueness" => "node global", "relationships" => {"type"=> "attended", "direction" => "in"}, "return filter" => { "language" => "javascript", "body" => "position.length() == 1 && position.endNode().getId() != #{student} && position.lastRelationship().getProperty(\"graduated\") == #{graduated};"}}) end Visualize it (sort of...
