Ruby on rails 当使用与模型中的外键的关系时，Rails中的SQLException

@discover.claimer.name和@discover.induced.name工作罚款。 但是当我尝试的时候

class User 
   has_many :disputes
end

class Dispute
    belongs_to :claimant, class_name: 'User', :foreign_key => :claimant_id
    belongs_to :indicted, class_name: 'User', :foreign_key => :indicted_id
end

我收到一个错误：SQLite3:：SQLException:没有这样的列：Disferences.user_id:从Disferences中选择1作为一个，其中Disferences.user_id=？限制1 出了什么问题以及如何解决？

感谢您的帮助

您似乎在以下位置使用了无效语法：

---

您正在传递布尔值，但应传递带有SQL查询条件的哈希。

我认为更改关联将解决您的问题

@user.disputes.where(claimant_id: @user.id)
@user.disputes.where(indicted_id: @user.id)

现在在控制台中，尝试这样做

class User < ActiveRecord::Base
  has_many :claimant_disputes, class_name: 'Dispute', foreign_key: "claimant_id"
  has_many :indicted_disputes, class_name: 'Dispute', foreign_key: "indicted_id"
end

class Dispute < ActiveRecord::Base
  belongs_to :user
end

您是否尝试过此@user.disfers.whereclaimer_id=？，@user.idname错误。我认为问题在于：user_id，在我的模式文件create_table中，force:true do | t | t.integer post_id t.string reason t.datetime created_at t.datetime updated_at t.integer s s_disjust_category_id t.integer w_disjust_category_id t.integer索赔人_idt.integer起诉的_idend我在表中看不到：user_id，因此，当我尝试使用@user.disferences ActiveRecord之类的关系时，请参见：用户id在争端中，但我有：被起诉的id和：原告id而不是：用户id。设计错误？我已经发布了答案，请检查

class User < ActiveRecord::Base
  has_many :claimant_disputes, class_name: 'Dispute', foreign_key: "claimant_id"
  has_many :indicted_disputes, class_name: 'Dispute', foreign_key: "indicted_id"
end

class Dispute < ActiveRecord::Base
  belongs_to :user
end
