关系的has_many/belongs_to的PG :: UndefinedColumn

Question

我得到这个错误当我这样做：

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 

如果你能帮助我知道这个错误在哪里，我会感谢你

附加foreign_key在你user.rb

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