TypeError：無法讀取未定義的屬性（讀取“查找”）

Question

我收到錯誤“TypeError: Cannot read properties of undefined (reading 'find')”，它指向代碼塊：

app.get('/Organizations', (req,res) => {
Organizations.find({}).then((organization) => {
    res.send(organization);
}); })

app.js，導入 mongoose 架構：

const {Organizations} = require('./db/models');

組織.model.js：

const mongoose = require('mongoose');

const OrganizationsSchema = new mongoose.Schema({
    organizationName:{
        type: String,
        required: true,
        minlength:1,
        trim: true
    }
})

    
const Organizations = mongoose.model( 'Organizations', OrganizationsSchema);

module.exports =  (Organizations)

index.js：

const { Organizations } = require('./Organizations.model');
module.exports = {
    Organizations
}

Answer 1

您在導出Organisations時添加了括號而不是括號。 試試這個：

const mongoose = require('mongoose');

const OrganizationsSchema = new mongoose.Schema({
    organizationName:{
        type: String,
        required: true,
        minlength:1,
        trim: true
    }
})

    
const Organizations = mongoose.model( 'Organizations', OrganizationsSchema);

module.exports =  {Organizations}
