Sequelize：belongsToMany和级联删除

Question

美好的一天。我有3张桌子：

1. 人：id，姓名
2. 地点：id，name
3. PeoplePlaces：id，person_id，place_id

我有这些表的模型：

function Person(Sequelize, sequelize) {
  return sequelize.define('people', {
    id: {
      type: Sequelize.INTEGER,
      primaryKey: true,
      autoIncrement: true
    },
    firstName: {
        type: Sequelize.STRING,
        allowNull: false
    },
    lastName: {
        type: Sequelize.STRING,
        allowNull: false
    },
    birthdate: {
        type: Sequelize.DATE,
        allowNull: false
    }
  }, {
      timestamps: false
  });
}

function Place(Sequelize, sequelize) {
  return sequelize.define('places', {
    id: {
      type: Sequelize.INTEGER,
      primaryKey: true,
      autoIncrement: true
    },
    name: {
        type: Sequelize.STRING,
        allowNull: false
    }
  }, {
      timestamps: false
  });
}

function PersonPlace(Sequelize, sequelize) {
  return sequelize.define('peopleplaces', {
    id: {
      type: Sequelize.INTEGER,
      primaryKey: true,
      autoIncrement: true
    }
  }, {
      timestamps: false
  });
}

所以，例如我想删除id = 1的人：

sequelize.people.destroy({ where: { personId: pId } })

但我在删除时遇到错误，对我说表PersonPlaces包含FK到Person并且无法删除。

我尝试使用onDelete: 'cascade'：People.belongsToMany(Places, { through: PeoplePlaces, onDelete: 'cascade' });

但没有好结果。

那么，我如何从People删除PeoplePlaces中有FK的人？
