ruby on rails - How to store ObjectID in MongoDb without references? -


i have 3 models:

class user   include mongoid::document   field :name, :type => string    has_many :comments   embeds_many :posts end  class post   include mongoid::document   field :title, :type => string   field :body, :type => string    embeds_many :comments   belongs_to :user end  class comment   include mongoid::document   field :text, :type => string    belongs_to :user   embedded_in :post end

and have error:

referencing a(n) comment document user document via relational association not allowed since comment embedded.

ok, thats right. how can store, wrote comment?

the belongs_to user in comment what's throwing off. use normal field store foreign key.

class comment   include mongoid::document    embedded_in :post    field :text, :type => string   field :commenter_id end
