我想存储一组嵌套的子文档，例如下面的一个：
[
{"2021-02-01income":{"value":37.95,"tax":0,"type":"income"}},
{"2021-03-01income":{"value":38.25,"tax":0,"type":"income"}},
{"2021-03-08fund": {"value":-78,"type":"fund","transaction":"610378deead56742a898443b"}},
{"2021-04-01income":{"value":38.53,"tax":0,"type":"income"}},
{"2021-07-01income":{"type":"income","tax":0,"value":134}},
]
我想出了以下不起作用的架构，因为您可以看到对象数组基于唯一键嵌套对象......我可以尝试任何解决方法：
const incomeSchema = mongoose.Schema({
type: { type: String, required: true },
value: { type: Number, required: true },
tax: { type: Number, required: false },
transaction: {
type: mongoose.Schema.Types.ObjectId,
required: false,
ref: 'Transaction',
},
});
const investmentSchema = mongoose.Schema(
{
incomes: [{ type: incomeSchema }],
name: { type: String, required: true },
user: {
type: mongoose.Schema.Types.ObjectId,
required: false,
ref: 'User',
},
account: {
type: mongoose.Schema.Types.ObjectId,
required: true,
ref: 'Account',
},
broker: {
type: mongoose.Schema.Types.ObjectId,
required: true,
ref: 'Broker',
},
type: { type: String, required: true },
rate: { type: String, required: true },
indexer: { type: String, required: true },
investment_date: { type: Date, required: true },
due_date: { type: Date, required: true },
initial_amount: { type: Number, required: true },
accrued_income: { type: Number, required: false, default: 0 },
taxes: { type: Number, required: false, default: 0 },
},
{ timestamps: true }
);
const Investment = mongoose.model('Investment', investmentSchema);
