在我的应用程序中,我需要实现4个功能:
我相信我已正确实施1.和2.我在follow.model
中创建了一个跟随模式,我在下面创建了follow.controller
两种方法,用于存储(跟随)和销毁(取消关注)。
现在我想实现3.和4.我在user.model
模式中创建了两个数组,一个用于跟随,一个用于跟随者。当我在user.controller
中返回用户时,如何填充以下和关注者数组?目前他们是空的。
follow.model.js
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
var FollowSchema = new Schema({
follower: {
type: Schema.Types.ObjectId,
ref: 'User'
},
followee: {
type: Schema.Types.ObjectId,
ref: 'User'
}
},
{
timestamps: {createdAt: 'created_at', updatedAt: 'updated_at'}
});
module.exports = mongoose.model('Follow', FollowSchema);
follow.controller.js
'use strict';
const User = require('../models/user.model');
const Follow = require('../models/follow.model');
class FollowController {
constructor() {
}
store(req, res) {
let follower = req.body.follower;
let followee = req.params.id;
let follow = new Follow({
follower: follower,
followee: followee,
});
follow.save(function (err) {
if (err) {
return res.status(404).json({
succes: false,
status: 404,
data: {},
message: "There was an error trying follow the user."
});
}
return res.status(200).json({
success: true,
status: 200,
data: follow,
message: 'Successfully followed user'
});
});
}
destroy(req, res) {
let follower = req.params.followerid;
let followee = req.params.id;
Follow.remove({ 'follower': follower, 'followee': followee }, (err, result) => {
if (err) {
return res.status(404).json({
success: false,
status: 404,
data: {},
message: "Error removing record"
});
}
return res.status(201).json({
success: true,
status: 201,
data: {},
message: "Successfully unfollowed user"
})
});
}
}
module.exports = FollowController;
user.model.js
let UserSchema = new Schema({
email: {
address: {
type: String,
lowercase: true,
//unique: true,
},
token: String,
verified: {
type: Boolean,
default: false,
},
},
password: {
type: String,
},
following: [{
type: Schema.Types.ObjectId, ref: 'Follow'
}],
followers: [{
type: Schema.Types.ObjectId, ref: 'Follow'
}],
{
timestamps: {createdAt: 'created_at', updatedAt: 'updated_at'}
});
user.controller.js
show(req, res) {
let id = req.params.id;
User.findOne({ '_id': id },
function (err, user) {
if (err) {
return res.json(err);
}
return res.json(user);
});
}
答案 0 :(得分:0)
您只需要populate这些字段:
User.findOne({ '_id': id }, (err, user) => {
if (err) return res.json(err);
return res.json(user);
}).populate([
{ path: 'following' },
{ path: 'followers' }
]);
