【问题描述】:
我正在尝试在 mongoDB 和节点中添加对我的 CompetitionEvent 对象的订阅。 我的问题是我只能编写一个订阅,而不能一个接一个地添加它们。 这是我的 http 文件:
const express = require('express')
import * as bodyParser from 'body-parser'
// import { eventApplication } from './compositionRoot'
import { CompetitionModel } from './mongo'
export const app = express()
app.use(bodyParser.json())
// WORKS - find all events
app.get('/events', async (_req: any, res: any) => {
const comp = await CompetitionModel.find()
res.send(comp)
})
// WOKRS - find just one event
app.get('/events/:event_id', async (req: any, res: any) => {
const searchedComp = await CompetitionModel.find(req.params)
res.send(searchedComp)
})
// WORKS - posts a new comp event
app.post('/new-comp', async (req: any, res: any) => {
const data = await new CompetitionModel(req.body).save()
res.json(data)
})
// WORKS - posts a new subscription into a comp
app.put('/update/:event_id', async (req: any, res: any) => {
const subs = await CompetitionModel.findOneAndUpdate(
{ event_id: req.params.event_id },
{ subscriptions: req.body },
)
res.send(subs)
})
// TO TEST - deletes a competition event
app.delete('/delete/:event_id', async (req: any, res: any) => {
const toDel = await CompetitionModel.deleteOne({
event_id: req.params.event_id,
})
res.json(toDel)
})
这是我的 mongo 文件:
const mongoose = require('mongoose')
mongoose.connect('mongodb://localhost:27017/CompetitionEvent')
export const CompetitionSchema = new mongoose.Schema({
event_id: String,
compName: String,
place: String,
time: String,
subscriptions: [],
date: Date,
cost: {
currency: String,
amount: Number,
},
})
export const CompetitionModel = mongoose.model(
'CompetitionModel',
CompetitionSchema,
)
export const connection = () =>
new Promise((resolve, reject) => {
mongoose.connection.once('open', () => {
resolve()
})
mongoose.connection.once('error', () => {
reject('oooooh shit')
})
})
每次我尝试更改它时,它要么不修改竞争事件,不添加任何内容,要么只是用新订阅替换旧订阅,这没什么意义,我相信你会同意
