Sequelize.js 模型具有 manufacturedFrom 和 manufacturedTo 属性。如何获取特定年份生产的所有车型？

Question

我有以下 Model/Table:

Table: models
Columns: name, manufacturedFrom, manufacturedTo

和一些示例记录：

5 Series    2010    2017
6 Series    2011    2018
X4 (F26)    2014    2018

现在假设我想获取 2018 年生产的所有型号。这意味着我只会获取这 2 个：

6 Series    2011    2018
X4 (F26)    2014    2018

现在我得到的所有模型都是这样的：

let Model = require('../models/Model')

module.exports.getModels = async (req, res, next) => {

    let response = await Model.findAll()

    res.status(200).json({
        models: response
    })

}

问题是我不太清楚应该使用哪种运算符来获取这些记录。我尝试了一些大于和小于的东西，但我不太成功。

Answer 1

只需像这样使用 [Op.gte] 和 [Op.lte]：

const year = '2018';
let response = await Model.findAll({
  where: {
    manufacturedFrom: {
      [Op.lte]: year
    },
    manufacturedTo: {
      [Op.gte]: year
    }
  }
})
