我有三个模型,每个模型都有以下关联:
class Model1 < ActiveRecord::Base has_many :model2s has_many :model3s end class Model2 < ActiveRecord::Base belongs_to :model1 has_many :model3s,:through => :model1 # will this work? is there any way around this? end class Model3 < ActiveRecord::Base belongs_to :model1 has_many :model2s,:through => :model1 # will this work? is there any way around this? end
