Question

我正在使用Node express和mongoDB创建事件管理应用程序。基本上，它具有3个模型，分别为User，Programme和Event。 Programme可能包含多个事件，例如Sports-Meet是一个Programme。它包含以下事件：

1. Welcoming Chiefguest
2. Silence Pray
3. Hoist the Flag
4. Mark Fast
5. Lightning the Torch
6. Events
7. Interval Programme
8. Prize giving
9. Vote of Thanks

这些事件具有order属性，以确定在哪个事件之后的哪个事件。基本上，这是运动会计划中事件的顺序。但是用户可以在事件进行过程中更改事件顺序，那时其他观众正在观看事件（议程）列表，而用户将事件的顺序更改（例如，将电筒从5更改为4），立即显示给观众。如何在API级别执行此请求？

以下是上述模型的架构：

UserModel.js

const mongoose = require('mongoose');

const UserSchema = mongoose.Schema({
    name: {type:String},
    email: {type:String},
    password: {type:String}
},
{timestamps:true}
);

module.exports = mongoose.model('User', UserSchema);

ProgrammeModel.js

const mongoose = require('mongoose');

const programmeSchema = mongoose.Schema({
    name: { type: String, required: true },
    timefrom: { type :Date,required: true },
    timeto: { type :Date,required: true },
    status: { type: String, required: true },
    venue: { type: String, required: true },
    timetype: { type: Number, required: true },
    protype: { type: String, required: true },
    userid:{ type:mongoose.Schema.Types.ObjectId,ref : 'User', required: false },
    logo :{ type: String, required: true }

});

module.exports = mongoose.model('Programme', programmeSchema);

EventModel.js

const mongoose = require('mongoose');

const eventSchema = mongoose.Schema({
    name: { type: String, required: true },
    timefrom: { type :Date,required: true },
    timeto: { type :Date,required: true },
    status: { type: String, required: true },
    proid: { type:mongoose.Schema.Types.ObjectId,ref :'Programe', required: true},
    proorder: { type: String, required: true }
});

module.exports = mongoose.model('Event', eventSchema);

如何为议程程序进行实时更改的API？
