Question

我有这样的模式

var Schema = mongoose.Schema;

var schema = new Schema({
    uid : {type: String, required: true},
    title: {type: String, required: true},
    description: {type: String, required: true}
})

module.exports = mongoose.model('Task', schema)

在另一个文件中，我包括了该文件，并尝试为数据库设置种子：

var Task = require('../models/task');
var uuid4 = require('uuid4')
var mongoose = require('mongoose')
mongoose.Promise = global.Promise;

mongoose.connect('mongodb://localhost:27017/app', {useNewUrlParser: true});
var task = new Task({
    uid: uuid4(),
    title: 'task3 name',
    description: 'task3 desc'
})
task.save(function (err) {
     if (err) console.log(err)
  })
}

无论我做什么，都不会保存我想要的数据。现在，当我进入数据库，应用程序数据库，任务集合时，那边没有插入

根据this documentation

如果创建自定义连接，请改用该连接的model（）函数。

因此，您需要从连接中声明模型，以便它知道与var connection = mongoose.createConnection('mongodb://localhost:27017/test'); var Tank = connection.model('Tank', yourSchema);动作相关联的连接。

我建议创建一个专用的.save()文件来处理创建连接的过程，然后可以将其导入到每个模式文件中，以便从提供的连接中创建模型。

无法使用mongoose将文档保存到mongodb
