post 作者 ID 在节点 js 中变成作者用户名 mongodb
post author Id turn into author username in node js for mongodb
我想在前端显示我的 post 的作者姓名。所以我想根据它的用户 ID 找到 post。但在模型模式中,我在 post 模式中使用了用户的对象 ID。
这是我的用户架构:
const mongoose = require('mongoose');
// user schema
const userSchema = new mongoose.Schema(
{
email: {
type: String,
trim: true,
required: true,
unique: true,
lowercase: true
},
name: {
type: String,
trim: true,
},
password: {
type: String,
required: true
},
salt: String,
bio: {
type: String,
trim: true
},
role: {
type: String,
default: 'subscriber'
},
resetPasswordToken: String,
resetPasswordExpire: Date,
},
{
timestamps: true
}
);
module.exports = mongoose.model('User', userSchema);
这是我的post架构模型:
const mongoose = require("mongoose");
const PostSchema = new mongoose.Schema({
title: {
type: String,
required: true,
},
content: {
type: String,
required: true,
},
comments: [{
text: String,
created: { type: Date, default: Date.now },
postedBy: { type: mongoose.Schema.ObjectId, ref: 'User'}
}],
created: {
type: Date,
default: Date.now
},
creator: {
type: mongoose.Schema.Types.ObjectId,
ref: "User",
},
},
{
timestamps: true,
},
);
const Post = mongoose.model("Post", PostSchema);
module.exports = Post;
这是我的 post 特定用户 ID 列表的路由器:
exports.postByUser=async(req,res)=>{
try
{
const userID=async()=>{
await User.findById({ _id:req.params.id})
.then(posts=>{
res.status(200).json(posts.name)
})
}
await Post.find({creator: req.params.id})
.then(posts=>{
res.status(200).json(posts)
})
}catch(error){
res.status(500).send({error: error.message});
};
}
router.route('/post/mypost/:id').get(requireSignin,postByUser);
我的目标是获得一个 post 列表,其中每个 post 的创建者都会有用户名。我怎样才能在 nodejs 中实现它?
我是这样解决的:
exports.postByUser=async(req,res)=>{
try
{
await Post.find({creator: req.params.id})
.populate({path:'creator', select:'name -_id'})
.then(post=>{
res.status(200).json(post)
})
}catch(error){
res.status(500).send({error: error.message});
};
}
成功了
