无限种群猫鼬Node js

Question

我有两个型号，它们是(表单，用户(

每个用户都有formId字段，该字段是他拥有的表单对象的对象id

每个表单都有一个名为userId的字段，该字段用于拥有该表单的用户

问题是，我使用的是mongoose自动填充包，如果我将formId和userId字段更改为自动填充，它将打开一个没有结束的无限填充

问题是，一些其他模式有一个名为formId的字段，它与表单对象相关联，在这种情况下，我想填充userId字段以获得用户信息，而不需要再次填充formId字段。

架构设计

const userSchema = new Schema({
name: String,
age: Number,
formId: {
type: Schema.Types.ObjectId,
ref: 'Form',

//this value used to auto populate for mongoose-autopopulate package
autopopulate: true,
},
})
//signing the mongoose-autopopulate plugin
...
//exporting the module


---------------

const formSchema = new Schema({
address: String,
bill: Number,
//the id of the user who added this form
userId: {
type: Schema.Types.ObjectId,
ref: 'User',

//this value used to auto populate for mongoose-autopopulate package
autopopulate: true,
},
})
//signing the mongoose-autopopulate plugin
...
//exporting the module


----------

const orderSchema = new Schema({
products: [],
deliveryBoy: {
type: Schema.Types.ObjectId,
ref: 'Boy',
},
formId: {
type: Schema.Types.ObjectId,
ref: 'Form',

//this value used to auto populate for mongoose-autopopulate package
autopopulate: true,
},
})
//signing the mongoose-autopopulate plugin
...
//exporting the module

使用maxDepth选项猫鼬自动填充

例如

const orderSchema = new Schema({
products: [],
deliveryBoy: {
type: Schema.Types.ObjectId,
ref: 'Boy',
},
formId: {
type: Schema.Types.ObjectId,
ref: 'Form',
autopopulate: { maxDepth: 2 },
},
})
