Question

我有两个mongoose模式'user'和'project'，我想在mysql中显示这些模式之间的关系。这该怎么做？如何在创建项目时传递用户？

user.js的

const mongoose = require('mongoose');
const bcrypt = require('bcrypt-nodejs');
const Schema = mongoose.Schema();

const UserSchema = mongoose.Schema({
    fullname: {type: String},
    username : {type:String},
    password: {type:String}
});

UserSchema.methods.encryptPassword = function(password) {
    return bcrypt.hashSync(password, bcrypt.genSaltSync(10), null);
};
UserSchema.methods.comparePassword = function(userPassword, cb) {
    bcrypt.compare(userPassword, this.password, (err, isMatch) => {
        if(err) throw err;
        cb(null, isMatch);
    });
}
module.exports = mongoose.model('User', UserSchema);

project.js

const mongoose = require('mongoose');
const Schema = mongoose.Schema();
const User = require('./user');

const ProjectSchema = mongoose.Schema({
    title: {type: String, required: true},
    description: {type:String},
    created_at: { type: Date, default: Date.now },
    publish : { type: Boolean, default: false}
});

module.exports = mongoose.model('Project', ProjectSchema);

在Mongoose中创建模式与在Relational DBMS中创建模式不同，例如MySQL，PostGreSQL。

您可以使用objectId，bro。

如果一个项目只能由一个用户处理，你可以使用这样的东西。

userId: {
    type: mongoose.Schema.Types.ObjectId,
    ref: 'User'
}

但是如果一个项目由多个用户处理

users: [{
    type: mongoose.Schema.Types.ObjectId,
    ref: 'User'
}]

希望它会有所帮助
