javascript - 从表的字段返回值

Question

我尝试使用 promise 返回表字段的值，但结果显示如下

router.get("/generateDemand", (req, res, next) => {
  const entreprise = req.user.entrepriseid;

  downloadFile(req, res, next, entreprise);
});

export const downloadFile = async (req, res, next, entreprise) => {
  const title1 = await Entreprise.findOne({
    attributes: ["entrepriseid", "titrefr"],
    where: { entrepriseid: entreprise }
  });
  console.log("title---------->", chalk.bgBlue(title1));
}

....

Executing (default): SELECT "entrepriseid", "titrefr" FROM "entreprise" AS "entreprise" WHERE "entreprise"."entrepriseid" = 'SDA'; title----------> [object SequelizeInstance:entreprise] GET /attachment/generateDemand 200 71.459 ms - 1638

Answer 1

通过调用 findOne 方法返回单个 Sequelize 模型实例，因此为了获得给定实例的指定字段(表记录的表示)，您应该使用 instance.get 方法，如 chalk.bgBlue(title1.get('fieldName'))
