def self.default_path
  if defined?(Rails)
    Rails.root.join('config', 'cypher_databases.yml')
  else
    File.join(Dir.pwd, 'config', 'cypher_databases.yml')
  end
end

.for(name = :primary, env: nil, path: nil) ⇒ Object

Read config/cypher_databases.yml the Rails‑native way and then pick a *named connection* (default :primary).

Works outside Rails too by falling back to ActiveSupport::ConfigurationFile.
