node.js - Sequelize .save() 在实例上不起作用

Question

我有一个定义如下的模型。然后我尝试运行它下面的代码来更新检索到的实例的 isTeamLead 属性，但我收到错误 teamMember.save() is not a function 。

  const TeamMember = sequelize.define('teamMember', {
    userId: Sequelize.INTEGER,
    teamId: Sequelize.INTEGER,
    slotNumber: Sequelize.INTEGER,
    isTeamLead: Sequelize.BOOLEAN
  });


    Promise.all([db.models.TeamMember.findOne({ where: { $and: [{ userId: lead.id }, { teamId: id }] } })]).then((teamMember) => { teamMember.isTeamLead = true; teamMember.save() });

Answer 1

我能够通过确保我在实例上运行来解决这个问题。上面我操作的是数组而不是实际的 teamMember 实例。

    Promise.all([db.models.TeamMember.findOne({ where: { $and: [{ userId: lead.id }, { teamId: id }] } })]).then((teamMember) => { teamMember[0].isTeamLead = true; teamMember[0].save() });
