Question

我对onTorchModeChanged(0, false) onTorchModeChanged(0, false) onTorchModeUnavailable(0) onTorchModeUnavailable(0) NODEJS框架很陌生。我需要更新下面显示的hapi子文档

MongoDB

这是我的用户架构我需要更新{ "_id" : ObjectId("5bd1a22819e3e84e9dcae197"), "userPrivacy" : { "bio" : { "aboutMe" : "only_me" }, "userGallery" : { "album" : "connections", "images" : "connections", "videos" : "connections" } }, "following" : [], "followers" : [], "invites" : [], "referrals" : [], "userId" : ObjectId("5bd1a22819e3e84e9dcae196") } userPrivacy

中的所有文档

我已经为此编写了控制器：

( "bio" ,"userGallery" )

和数据库操作通过以下方式完成：

exports.updatePrivacyDefaults = {
    description: 'update default privacy ',

    tags: ['api'],

    auth: {
        mode: 'try',
        strategy: 'session'
    },

    validate: {
        payload: {
            about: Joi.string().required().allow(''),

            album: Joi.string().required().allow(''),
            image: Joi.string().required().allow(''),
            video: Joi.string().required().allow(''),
        },
        failAction: (request, h, error) => {
            request.yar.flash('error', error.details[0].message);
            return h.redirect('/settings').takeover();
        }
    },

    handler: async (request, h) => {
        try {

            if (request.auth.isAuthenticated) {

                // let userDetails = request.auth.credentials;
                let incomingData = {
                    aboutMe: request.payload.about,                        

                    album: request.payload.album,
                    images: request.payload.image,
                    videos: request.payload.video,
                };
                try {
                    if (incomingData) {
                        console.log('data to update = ', incomingData);
                        let settingsUpdate = await settingHelper.updatePrivacySettings(request.auth.credentials._id, incomingData);
                        if (settingsUpdate.statusCode === 200) {
                            let UpdateData = settingsUpdate.userData;
                            request.yar.flash('success', UpdateData.message);
                            return h.redirect('/settings/privacy_settings');
                        }
                        // return h.view('setting/privacy_settings',{ user: userDetails});
                    }

                } catch (error) {
                    logger.error(error);
                    request.yar.flash('error', error.message);
                    return h.redirect('/lounge');
                }

                // return h.view('setting/privacy_settings',{ user: userDetails});             
            }
            else {
                return h.redirect('/login');
            }
        } catch (error) {
            logger.error(error);
        }
    }
};

我知道将无法正常工作，因为我正在尝试更新文档中的文档有人，请帮我解决。我花了将近2天的时间来解决它，但没有结果

Mongo不知道如何处理incomingData。您需要指定要更新的字段。在这种情况下，您可以执行以下操作：

    let updatedPrivacyData = await UserDetails.findOneAndUpdate({
        { userId : user_id }, // query
        { userPrivacy.bio.aboutMe : incomingData.aboutMe, // data to update
          userGallery.album : incomingData.album,
          userGallery.images : incomingData.image,
          userGallery.videos : incomingData.video }
    });

另请参见mongoose api docs for findOneAndUpdate

您绝对应该研究使用模式：
