使用额外的列将多对多序列化

问题描述

经过一番研究，我没有发现与我的问题相关的任何内容.所以设置是已经与 sequelize (sqllite) 一起工作的 M:M 关系:

After some research I didn't find anything related to my problem. So the setting is an M:M relationship already working with sequelize (sqllite):

return User.find({ where: { _id: userId } }).then(user => {
   logger.info(`UserController - found user`);
   Notification.find({ where: { _id: notificationId } }).then(notification => {
      if (associate) {
        return user.addNotification([notification]);
      } else {
        return user.removeNotification([notification]);
      }
   })
})

问题是我在 inter 表(cityId，active)中有额外的字段，我不知道如何在运行addNotification"时更新它.

The thing is that I have extra fields in the inter table(cityId, active) and I don't know how to update it when running "addNotification".

提前致谢

推荐答案

如果您使用的是 Sequelize 4.x 版，API 中有一些变化

If you are using Sequelize version 4.x there is some changes in the API

关系添加/设置/创建设置器现在通过将属性作为 options.through 传递来设置它们(以前第二个参数被用作通过属性，现在它被认为是通过作为子选项的选项)

Relationships add/set/create setters now set through attributes by passing them as options.through (previously second argument was used as through attributes, now its considered options with through being a sub option)

user.addNotification(notification, { through: {cityId: 1, active: true}});
