如何通过与neo4j和rails的关联实现多对多

Question

我想要两个模型之间的多对多关联。正常的Rails关联示例如下：

class A < ApplicationRecord
  has_many :abs
  has_many :bs, through: :abs
end

class B < ApplicationRecord
  has_many :abs
  has_many :as, through: :abs
end

class AB < ApplicationRecord
  belongs_to :a
  belongs_to :b
end

neo4j如何处理？
