通过 Sequelize 过滤相关模型

Question

我的应用程序中有两个模型，Delivery 和 DeliveryProblem。 DeliveryProblem 有一个来自 Delivery 的 PK (delivery_id)：

static associate(models) {
    this.belongsTo(models.Delivery, {
      foreignKey: 'delivery_id',
      as: 'delivery',
    });
  }

我需要 select 所有有交付问题的交付。 在我的 Controller 中，有以下方法：

async index(req, res) {
    const response = await DeliveryProblem.findAll({
      order: ['id'],
      attributes: ['delivery_id'],
    });

    // Filter all Deliveries with problem
    const ids = [...new Set(response.map((x) => x.delivery_id))];

    const deliveries = Delivery.findAll({
      where: , // <<< How can I filter ?
      order: ['id'],
    });

    return res.json(deliveries);
  }

Answer 1

const Sequelize = require('sequelize')
const Op = Sequelize.Op
...
// Filter all Deliveries with problem
const ids = [...new Set(response.map((x) => x.delivery_id))];
const deliveries = Delivery.findAll({
  where: {
   id: {
     [Op.in]: ids
   }
  },
  order: ['id'],
});
