获取 TypeError：使用 Mongoose 时无法读取未定义的属性（读取“查找”）答案

【问题标题】：Mongoose, getting TypeError: Cannot read properties of undefined (reading 'find')获取 TypeError：使用 Mongoose 时无法读取未定义的属性（读取“查找”）

【问题描述】：

我收到错误，TypeError: Cannot read properties of undefined (reading 'find') 指向代码块：

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

app.js，导入猫鼬模式：

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

Organization.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
}

【问题讨论】：

你能说明你在哪里导出和导入Organizations 吗？

标签： javascript node.js mongodb express mongoose

【解决方案1】：

您在导出 Organisations 时添加了圆括号而不是方括号。试试这个：

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}
