unrelate() 似乎没有更改或删除连接 table

Question

UserTagAnswer 模型：

  answer: {
    relation: Model.ManyToManyRelation,
    modelClass: sails.config.models.UserTagAnswerOptions,
    join: {
      from: 'usertaganswer.id',
      through: {
        from: 'usertaganswer_answeredoptions.userTagAnswerId',
        to: 'usertaganswer_answeredoptions.userTagAnswerOptionId'
      },
      to: 'usertagansweroptions.id'
    }
  },

UserTagAnswerOptions 模型

  userTagAnswers: {
    relation: Model.ManyToManyRelation,
    modelClass: sails.config.models.UserTagAnswer,
    join: {
      from: 'usertagansweroptions.id',
      through: {
        from: 'usertaganswer_answeredoptions.userTagAnswerOptionId',
        to: 'usertaganswer_answeredoptions.userTagAnswerId'
      },
      to: 'usertaganswer.id'
    }
  },

我在数据库中看到连接 table usertaganswer_answeredoptions 中有一行包含所有预期信息。但我现在想删除该行。我试试这个：

theAnswer = await UserTagAnswer.query()
    .where(inputs.userType + "Id", inputs.answeringUserId)
    .where('tagId', answerObject.tag)
    .eager('tag');

theAnswer[0].$relatedQuery('answer')
    .unrelate();

我试图删除 'answer' 字段中的所有关系，但数据库中似乎没有任何变化。

Answer 1

我忘记了 unrelate() 调用中的 await 关键字。最终工作代码是：

await theAnswer[0].$relatedQuery('answer')
    .unrelate();
