如何更新嵌套的 mongo 对象

Question

I am trying to make a report function for my app

in the front end I make a put request :

.put(`http://localhost:3000/api/posts/report`, {
                        params: {
                            id: mongoId,
                            reportInfo: {
                                reported: true,
                                reportingUser: id
                            }
                        }
                    })

to this backend route

router.put('/report', (req, res, next) => {
    postModel.findOneAndUpdate(
        { _id: mongoose.Types.ObjectId(req.query.id) },
        req.query,
        { new: true, useFindAndModify: false },
        (error, returnedDocuments) => {
            if (error) return next(error);
            res.json(returnedDocuments);
        }
    );
});

for this model

const postSchema = new mongoose.Schema(
    {
        title: { type: String },
        description: { type: String },
        image: { type: String },
        price: { type: String },
        location: { type: String },
        image: { type: Array },
        author: {
            type: String,
            ref: 'User'
        },
        reportInfo: {
            reported:{
                type: Boolean,
                default: false
            },

            reportingUser:{
            type: String
            }

        }
    },
    {
        timestamps: true
    }
);

any ideas why it is not updating the reportInfo object , do I need to do something if there are some nested objects contained?

thanks

Your code tries to replace entires MongoDB document. Try to use $set instead of passing req.query directly:

{ $set: { reportInfo: req.query.reportInfo } }

I would also check if there should be req.query or req.body so just print the value to make sure that it gets deserialized properly.
