关系 has_many/belongs_to PG::UndefinedColumn

Question

我在执行此操作时遇到此错误：

user.owned_tipsters

错误：

ActiveRecord::StatementInvalid: PG::UndefinedColumn: ERREUR:  column tipsters.user_id does not exist

我的代码：

class User < ActiveRecord::Base

   has_many :owned_tipsters, class_name: 'Tipster', inverse_of: :owner
end

class Tipster < ActiveRecord::Base

  belongs_to :owner, class_name: 'User', inverse_of: :owned_tipsters
end

如果你能帮我知道这个错误在哪里，我会感谢你

鲍里斯 谢谢

Answer 1

在你里面加foreign_keyuser.rb

class User < ActiveRecord::Base
  has_many :owned_tipsters, class_name: 'Tipster', inverse_of: :owner, foreign_key: 'owner_id'
end
