[英]How to add reference of one schema to another in Mongoose and inserting data by json?
I am writing a node.js app where I have two mongoose schemas Wallet and User .我正在编写一个 node.js 应用程序,其中有两个 mongoose 模式Wallet和User 。
I have written the schemas like this:我已经写了这样的模式:
user.js用户.js
var mongoose = require('mongoose');
var userSchema = new mongoose.Schema({
userId: {type: String},
isAdmin: {type: Boolean, default: false},
password: {type: String},
name: {type: String},
wallet: {type: mongoose.Schema.Types.ObjectId, ref: 'Wallet'} //see here
});
module.exports = mongoose.model('User', userSchema);
Is the way I referenced wallet above, correct?我上面提到的钱包的方式对吗? If not, can you tell me the right way?如果没有,你能告诉我正确的方法吗?
wallet.js钱包.js
var mongoose = require('mongoose');
var walletSchema = new mongoose.Schema({
money: {type: Number, default: 0, min: 0},
});
module.exports = mongoose.model('Wallet', walletSchema);
The following is my user route file.以下是我的用户路由文件。
userRoute.js用户路由.js
router.route('/user')
.post(function (req, res) {
var user = new User();
user.userId = req.body.userId;
user.password = req.body.password;
user.name = req.body.name;
user.isAdmin = req.body.isAdmin;
user.wallet = req.body.wallet; // see here
user.save(function(err, user){
if(err){
res.json({ message: 'Failure' });
return false;
}
res.json({ message: 'Success' });
});
})
Is the way I have assigned wallet to the user object correct?我将钱包分配给用户对象的方式是否正确? If not can you tell me the right way?如果没有,你能告诉我正确的方法吗?
Now I want to post raw json from Postman.现在我想从 Postman 发布原始 json。 What will the json look like? json 会是什么样子?
user.wallet = req.body.wallet
won't work. user.wallet = req.body.wallet
不起作用。
As far as User
is concerned user.wallet
is just a simple field of the type ObjectId that store a 24 char hex string-like object: 522abc...
.就User
而言, user.wallet
只是一个 ObjectId 类型的简单字段,它存储一个 24 个字符的十六进制字符串对象: 522abc...
。
This "reference" is actually a higher level interpretation of Mongoose.这个“参考”其实是对猫鼬的更高层次的诠释。
That's why you can't directly do user.wallet = req.body.wallet
.这就是为什么你不能直接做user.wallet = req.body.wallet
。 You have to do something like this:你必须做这样的事情:
var user = new User();
…
// user.wallet = req.body.wallet; // won't work
var wallet = new Wallet(req.body.wallet) // because Wallet too is a Schema just like User
user.wallet = wallet.id;
…
