Typegoose + nestjs + mongodb:未使用@index修饰器创建索引

Question

我遇到了typegoose错误。我有一个名为SP的模型，我必须在它的属性上创建名为geoLocation的2dsphere索引我尝试了typegoose装饰器@index，但它不工作，甚至它没有抛出任何错误，我不知道发生了什么以及typegoose如何处理它。有没有人给我这个问题的解决方案?。

代码：

import { Prop, index, modelOptions, Severity } from '@typegoose/typegoose';
import { BaseModel } from '../base.model';
import { Factory } from 'nestjs-seeder';

export enum SPStatus {
    INAVTIVE = "INAVTIVE",
    ACTIVE = "ACTIVE",
}

@modelOptions({ options: { allowMixed: Severity.ALLOW } })
@index({ geoLocation: '2dsphere' }, {})
export class SP extends BaseModel{
    @Factory(faker => faker.company.companyName())
    @Prop({ required: true, index: true, text: true })
    businessName : string
    
    @Factory(faker => {
        let data = {
            type : "Point",
            coordinates:[Number(faker.address.longitude()), Number(faker.address.latitude())]
        }
        console.log(data);

        return data;
    })
    @Prop({ required: false })
    geoLocation: {
        type: string,
        coordinates: [number]
    }
}

Answer 1

试试下面的代码，它对我很有效

@index({ location: '2dsphere' })
export class GPSData extends Typegoose{    
    
    @prop({ required: true })
    public log_Id!: mongoose.Types.ObjectId;

    @ValidateNested({each: true})
    @prop({
        _id : false
    })
    readonly location: Location;
}

export class Location extends Typegoose{  
   
    @prop()
    @IsString({message: " type should be text"})
    readonly type: String;

    @prop({ required: true })
    coordinates: [[Number]];
}

示例集合(类型可以是"Point“、"MultiPoint”、"LineString“、"MultiLineString”、"Polygon“、"MultiPolygon”和“GeometryCollection”之一)：

{ 
"log_Id": "5fbdec08ce02d61fec9a0189",

"location":{
    "type":"MultiPoint",
    "coordinates":[
 [ -73.9580, 40.8003 ],
 [ -73.9498, 40.7968 ],
 [ -73.9737, 40.7648 ],
 [ -73.9814, 40.7681 ]
 ]  
}
}
