正在更新Mongoose对象

Question

我有两个MongoDB集合：crystals&cleanses

Crystal架构：

const crystalSchema = mongoose.Schema({
crystalInfo: {
title: {
type: String,
required: [true, 'Crystal title is required']
},
subtitle: {
type: String
},
description: {
type: String
},
category: {
type: String
},
chakras: {
type: String
},
astroSign: {
type: String
},
cleaningTips: {
type: String
},
thumbnail: {
type: String
},
largeImage: {
type: String
},
publishedDate: {
type: Date,
default: Date.now
},
affiliateLink: {
type: String,
require: [true, 'Affiliate link is required']
},
etsyLink: {
type: String
},
psychicTree: {
type: String
}
}
});

清洁方案：

const cleanseSchema = mongoose.Schema({
cleanseInfo:{
title:{
type: String,
required: [true, 'Cleanse title is required']
},
subtitle:{
type: String
},
description:{
type: String
},
duration: {
type: String
},
useFor: {
type: String
},
dontUse: {
type: String
},
icon:{
type: String
},
publishedDate:{
type: Date,
default: Date.now
},
}
});

我正在尝试更新crystalInfo对象，以包含任何清理提示数据，从而获得以下输出：

{
crystalInfo:
{
title: 'Abalone Shell',
subtitle: ...,
description: ...,
category: ...,
chakras: ...,
astroSign: ...,
cleaningTips: 'running_water',
thumbnail: ...,
largeImage: ...,
affiliateLink: ...,
etsyLink: ...,
psychicTree: ...,
publishedDate: 2020 - 10 - 06 T18: 38: 30.025 Z,
{
cleanseInfo:
{
title: 'Running Water',
subtitle: ...,
description: ...,
duration: ...,
useFor: ...,
dontUse: ...,
icon: 'running_water',
publishedDate: 2020 - 10 - 06 T18: 42: 34.627 Z
},
_id: 5 f6fa3a20b9f544d44a3ee7c,
__v: 0
}
},
_id: 5e17 c0db78fd3a1589289ddb,
__v: 0
}

当前功能：

Crystal.find().exec().then(crystals => {
let crystalTips = crystals.map(crystal => {
return crystal.crystalInfo.cleaningTips;
});
return Promise.all([
crystals,
Cleanse.find({
'cleanseInfo.icon': {
$in: crystalTips
}
}).exec()
]);
}).then(results => {
let crystals = results[0];
let cleansingTips = results[1];
crystals.forEach(crystal => {
crystal.crystalInfo.cleanse = cleansingTips.filter(tip => {
if(tip.cleanseInfo.icon === crystal.crystalInfo.cleaningTips){
return Object.assign(tip, crystal.crystalInfo); //This is the correct cleansing data but object is not updated?
}
});
});
console.log(crystals) //Object not updated
//return crystals;
}).catch(err => {
console.log(err);
});

如有任何协助，我们将不胜感激。

Answer 1

更新返回Object.assign((以获得正确的结果：

crystals.forEach(crystal => {
crystal.crystalInfo.cleanse = cleansingTips.filter(tip => {
if(tip.cleanseInfo.icon === crystal.crystalInfo.cleaningTips){
return crystal._doc.crystalInfo = Object.assign({cleanse: tip.cleanseInfo}, crystal._doc.crystalInfo)
}
});
});
