neo4j uuid is not created

问题

class Client
  include Neo4j::ActiveNode
end

> client = Client.new
 => #<Client uuid: nil, bot_client_id: nil, created_at: nil, email: nil, first_name: nil, last_name: nil, sms: nil, telegram_id: nil, updated_at: nil> 

My expectation is that the uuid would be populated.

回答1:

The uuid is only populated once the node object has been saved. So you could either do:

client = Client.create

Or:

client = Client.new
client.save
