 var mongoose = require('mongoose'), assert = require('assert'); var response = require ('response'); var forms = require('../models/forms-1'); // Connection URL var url = 'mongodb://localhost:27017/ezySchooling'; mongoose.connect(url); var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error:')); db.once('open', function () { // we're connected! console.log("Connected correctly to server"); // create a new user var newform = forms({ firstname: 'may', lastname : 'apo', dob : 25-05-1996, address : 'vaishali', phonenumber : 8447872060 }); // save the user newform.save(function (err) { if (err) throw err; console.log('form created!'); // get all the users forms.find({}, function (err, forms) { if (err) throw err; // object of all the users console.log(forms); db.collection('forms').drop(function () { db.close(); }); }); }); }); 

 var mongoose = require('mongoose'); var Schema = mongoose.Schema; // create a schema var formSchema = new Schema({ firstname: { type: String, //required: true, unique: true }, lastname: { type: String, //required: true, unique: true }, dob: { type: Date, required: true }, address: { type: String, required: true }, phonenumber: { type:Number , required: true } //timestamps: true }); // the schema is useless so far // we need to create a model using it var forms = mongoose.model('form', formSchema); // make this available to our Node applications module.exports = forms; 

我正在使用mongodb和mongoose运行rest API，我对app.js进行了所有相关更改，但我仍然无法在node.js中运行mongodb的任何功能。 我已经在该查询中附加了app.js和路由器文件，它们是路由器的形式。

好的，是的，如果“ forms”是您的猫鼬模型，则正确的语法是带有小写c的forms.create（....）。

*更新*好吧，根据您的评论，我仍然不确定您的应用程序结构； 事物使您的使用方式变得混乱。

无论如何，您想在路由器中拥有的是猫鼬生产的模型。 您可以这样操作：

var Form = mongoose.model('form'); // note that this assumes you've already called require on your ./models/forms.js file to run it and get the schema into mongoose

formRouter.route('/')
.post(function(req,res,next){
   Form.create(/* your args here and callback and stuff */);
});
