Rails Neo4j Migration Argument Error - ruby-on-rails

Question

So I have these two classes
class Tweet
include Neo4j::ActiveNode
property :content, type: String
property :created_at, type: DateTime
property :updated_at, type: DateTime
has_one(:user, :tweeted).from(:User)
end
class User
include Neo4j::ActiveNode
property :username, type: String
property :name, type: String
property :email, type: String, default: ''
validates :email, :username, uniqueness: true
property :encrypted_password
has_many(:Tweet, :tweeted)
end
And everytime I run rails neo4j:migrate it gives error like this
ArgumentError: The 'type' option must be specified( even if it is nil) or origin/rel_class must be specified (Class#tweeted)
How to properly create relationship between nodes in neo4jrb?

Answer 1

As the error message describes, you didn't explicitly define the type of your tweeted relation. Take a look at the official documentation for further details. However, the following should work:
class Tweet
include Neo4j::ActiveNode
property :content, type: String
property :created_at, type: DateTime
property :updated_at, type: DateTime
has_one :out, :author, type: :author, model_class: :User
end
class User
include Neo4j::ActiveNode
property :username, type: String
property :name, type: String
property :email, type: String, default: ''
validates :email, :username, uniqueness: true
property :encrypted_password
has_many :in, :tweets, origin: :author
end
