javascript - Mongoose ，出现类型错误 : Cannot read properties of undefined (reading 'find' )

Question

我收到错误，TypeError:无法读取未定义的属性(读取“find”)，它指向代码块:

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

app.js，导入 Mongoose 架构:

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

组织.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

这是一个导入/导出问题。在 Organization.model.js 中，导出 Organizations 时使用括号而不是大括号。像这样导出:

module.exports =  {Organizations}

并以这种方式导入:

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