node.js - 不能向 MongoDB 集合添加超过 1 个对象

问题描述

伙计们，我正在构建我的 NodeJS API，为此我将通过 mongoose 模块使用 MongoDB。

我创建了架构、控制器和所有端点都可以工作，但我只能创建第一个 POST。我的意思是，我可以在 MongoDB 的集合中创建 1 个对象，创建之后，如果我尝试向数据库中添加任何其他内容，我会得到一个 MongoError，我不知道该做什么，也没有找到互联网上的任何东西..

我希望你能帮助我...

这是架构：

const mongoose = require('mongoose');

const ProjectSchema = new mongoose.Schema({
    name: {
        type: String,
        required: true,
        unique: true
    },
    description: {
        type: String,
        required: true
    },
    app: {
        type: String,
        required: false,
    },
    github: {
        type: String,
        required: false,
    },
    logo: {
        type: String,
        required: false
    }
});

const Project = mongoose.model('project', ProjectSchema);

module.exports = Project;

控制器：

const Project = require("../models/ProjectSchema");

class ProjectController {
    async addNewProject(req, res) {
        try {
            const data = await Project.create(req.body);
            return res.send(data);
        } catch(error) {
            return res.send(error);
        }
    }
    
    async listAllProjects(req, res) {
        try {
            const data = await Project.find({});

            return res.send(data);
        } catch(error) {
            return res.send(error);
        }
    }
}

module.exports = new ProjectController();

POST 请求 JSON：

{
    "name": "name",
    "description": "description",
    "app": "app",
    "github": "github",
    "logo": "logo"
}

当数据添加到数据库时，我的 API 的预期响应是数据本身，如下所示：

{
  "_id": "603ac9d621540e1748b5d21f",
  "name": "name",
  "description": "description",
  "app": "app",
  "github": "github",
  "logo": "logo",
  "__v": 0
}

在第一个 POST 请求中，它确实发生了。但在那之后，这就是我得到的：

{
  "driver": true,
  "name": "MongoError",
  "index": 0,
  "code": 11000,
  "keyPattern": {
    "id": 1
  },
  "keyValue": {
    "id": null
  }
}

PS.：我已经尝试过使用旧版本的猫鼬，但我得到了同样的东西......就像猫鼬 5.11.15、5.11.17 和目前最新的 5.11.18。

提前致谢！

没有捕获的错误：
