如何使用 node.js 更新 object 中的值并续集

Question

I would like to update values (missions.status and missions.success) in the object, but I don't know how to approach it.

 "missions": { "missions": [ { "week": 1, "status": "", "mission": "do something", "success": "" } ] }

I tried to like this.

 //success.js router.put('/:id/result', async (req, res, next) => { const status = req.body.missions.missions[0].status; const success = req.body.missions.missions[0].success; try { const result = await models.User.findOne({ attribute: ['missions'], where: { id: req.params.id, }, }); const data = { result: result, }; let originalData = data.result.dataValues.missions.missions[0]; let weekdata = { status: status, success: success }; let resultData = Object.assign(originalData, weekdata); res.send({ data: resultData, message: 'good status changed', }); } catch (error) { console.log(error); res.sendStatus(400); } });

It is req.body and response, looks like it works, but doesn't update in databases. I don't know how to save that.

 //req.body { "missions": { "missions":[ { "status": "no", "success":"success" } ] } } // res.send { "data": { "week": 1, "status": "no", "mission": "do something", "success": "success" }, "message": "good status changed" }

You didn't call update for your model so that's why you'll get no changes in a DB. Try this:

await models.User.update(weekdata, {
      where: {
        id: req.params.id,
      },
    });
