Why Mongoose doesn't validate on update?

Question

I have this code

var ClientSchema = new Schema({
  name: {type: String, required: true, trim: true}
});

var Client = mongoose.mode(\'Client\', ClientSchema)         


        

Answer 1

exports.updateGroup = (request, response, next) => {
    const requestObj = request.body;
    var conditions = {
        _id: request.body._id,
        communityId: request.body.communityId
    };
    var newValues = {
        $set: requestObj
    };
    Group.updateOne(conditions, newValues, { ***runValidators: true*** }, (err, group) => {
        if (err) return response.json({
            message: "Updation of group failed",
            error: err,
            status: 500
        });
        response.json(group);
    });
};

You need to add { runValidators: true } as the third argument for validation to work on update.
