Ruby on rails 3 Rails模型与tables模型的关联

ruby-on-rails-3 ruby-on-rails-4

Ruby on rails 3 Rails模型与tables模型的关联,ruby-on-rails-3,ruby-on-rails-4,Ruby On Rails 3,Ruby On Rails 4,我想在无表模型上执行has\u one，属于关联 class A < ActiveRecord::Base has_one: b end class B < Tableless attr_accessor: b end class A

我想在无表模型上执行
has\u one，属于
关联


class A < ActiveRecord::Base
  has_one: b
end

class B < Tableless
   attr_accessor: b
end



class A


我想知道这在Rails中是否可行
您能在无表模型上定义关联吗？我会回答“不”。关联使用外键检索关联的记录，如果没有存储该外键的表，则无法检索该记录
