没有引用的Mongoose-Nest模式？

我有一个带有交易（银行交易）和重复交易（例如每月自动支付账单）的应用程序。我想定义一个RepeatingTransaction模式，该模式有一个基本事务字段，它可以在每次必须执行时复制到事务集合。我不想对引用执行此操作，因为应用程序使用应用程序其他部分中的事务集合。（我花了一些时间弄清楚业务逻辑，这样很好，我不想改变它）

理想的情况是，如果有一种方法可以将我的事务模式嵌套到RepeatingTransaction，以避免代码重复

---

那么，有没有一种不用引用就嵌套模式的方法呢？

您可以简单地做到这一点。只需将您的模式嵌套在其他模式中，它就可以正常工作

我做错的是，我试图在我的模式中加入一个模型。为了在我的

/model

文件夹中轻松解决问题，我有一个事务模型：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const TransactionSchema = require('./schemas/transaction-schema');

TransactionSchema.pre('save', function (next) {
    this.createdAt = new Date();
    next();
});

module.exports = mongoose.model('Transaction', TransactionSchema

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const TransactionSchema = require('./schemas/transaction-schema');

let RepeatingTransactionSchema = new Schema({
    user: {type: Schema.Types.ObjectId, ref: 'User'},
    transaction: {type: TransactionSchema, required: [true, 'Transation is required']},
    period: {type: String, required: [true, 'Interval is required']},
    nextDate: {type: Date, required: [true, 'Date is required']}
});

module.exports = mongoose.model('RepeatingTransaction', RepeatingTransactionSchema);

))

和一个重复传输模型：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const TransactionSchema = require('./schemas/transaction-schema');

TransactionSchema.pre('save', function (next) {
    this.createdAt = new Date();
    next();
});

module.exports = mongoose.model('Transaction', TransactionSchema

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const TransactionSchema = require('./schemas/transaction-schema');

let RepeatingTransactionSchema = new Schema({
    user: {type: Schema.Types.ObjectId, ref: 'User'},
    transaction: {type: TransactionSchema, required: [true, 'Transation is required']},
    period: {type: String, required: [true, 'Interval is required']},
    nextDate: {type: Date, required: [true, 'Date is required']}
});

module.exports = mongoose.model('RepeatingTransaction', RepeatingTransactionSchema);

当然还有一个交易模式：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

let TransactionSchema = new Schema({
    ...
});

module.exports = TransactionSchema;
