如何在猫鼬中进行原始mongodb操作? [英] How to do raw mongodb operations in mongoose?

问题描述

我之所以这样问是因为，当我编写单元测试时，我想删除测试数据库并插入一些初始化数据，还要在测试中检查mongodb中的数据.所以我需要对mongodb进行原始操作.

I'm asking this because when I write unit tests, I want to drop the test database and insert some initialize data, and also check the data in mongodb in testing. So I need raw operations to mongodb.

如何用猫鼬做到这一点?我现在能做的就是创建连接，而在mongoose的官方网站上找不到任何文档.

How to do this in mongoose? What I can do now is just create the connection, and not find any document in mongoose's official site.

 var mongoose = require('mongoose');
 mongoose.connect('mongo://localhost/shuzu_test');

 // get the connection
 var conn = mongoose.connection;

但是如何:

1. 删除数据库
2. 创建收藏集
3. 将一些数据写入集合
4. 查询集合
5. 删除收藏集

推荐答案

请参阅文档中有关驱动程序访问"的部分: http://mongoosejs.com/

See the section on "Driver Access" in the docs: http://mongoosejs.com/

基本上，您可以通过执行YourModel.collection来访问 node-mongodb-native 驱动程序，然后可以insert或remove或drop或任何您需要的内容.

Basically you can get access to the node-mongodb-native driver by doing YourModel.collection and then you can insert or remove or drop or whatever you need.

没有文档，但是通过这种方法，您可以在这里访问所有内容: https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/collection.js

There's not a doc, but with this approach you'll get access to everything in here: https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/collection.js

在您的情况下，您可能希望跳过在测试套件中使用猫鼬，而使用 node-mongodb-native ，甚至编写一个简单的 mongodb shell脚本，该脚本可以在测试开始之前运行.

In your case you may want to skip using mongoose in your test suite and use the node-mongodb-native directly, or even write a simple mongodb shell script that can be run before your tests start.
