ActiveRecord destroy has_many :through record from relational table

Question

物流和租赁请求通过 TypeLogistic table 属于彼此。我不小心创建了一个错误的 TypeLogistic，所以现在有两个：

TypeLogistic.where(rental_request_id:200).where(logistic_id:130)
=> #<ActiveRecord::Relation [#<TypeLogistic rental_request_id: 200, logistic_id: 130, type_of_logistics: nil>, #<TypeLogistic rental_request_id: 200, logistic_id: 130, type_of_logistics: "delivery">]>

如何销毁第一个？尝试了下面的运行，没有用

TypeLogistic.where(rental_request_id:200).where(logistic_id:130).first.destroy
PG::Error: ERROR:  zero-length delimited identifier at or near """"
LINE 1: DELETE FROM "type_logistics" WHERE "type_logistics"."" = 
                                                            ^

Answer 1

错误被抛出是因为 TypeLogistic 连接 table 没有主键。顺便说一句，这是它出现的默认设置，因为我按照说明创建了连接 table 而没有改变任何东西。

详细信息在这里：Rails Devise PG::SyntaxError: ERROR: zero-length delimited identifier at or near """"

解决方案？添加主键，请参阅下面的答案：
