@nestjs/mongoose module. Mongo collection has different properties than Mongoose model. I use aliases, but they return undefined results.
Mongo document

Minimized Schema only for two fields:
@Schema({ collection: 'accounts_slideshow' })
export class AccountSlideshow extends Document {
@Prop({ alias: 'limit', type: Number})
limit2: number
//@Prop({ type: SchemaFactory.createForClass(Filter), ref: () => Filter })
// filter2: Filter
// @Prop({ type: [ArchitectureItemSchema] })
// architecture: ArchitectureItem[]
@Prop({ alias: 'position' })
position2: string
}
export type AccountSlideshowDocument = AccountSlideshow & Document
export const AccountSlideshowSchema =
SchemaFactory.createForClass(AccountSlideshow)
Repository:
import { Injectable } from '@nestjs/common'
import { InjectModel } from '@nestjs/mongoose'
import { Model } from 'mongoose'
import {
AccountSlideshow,
AccountSlideshowDocument,
} from 'schemas/account.slideshow'
@Injectable()
export class AccountSlideshowsRepository {
constructor(
@InjectModel(AccountSlideshow.name)
private readonly _slideshowModel: Model<AccountSlideshowDocument>,
) {}
public async find(): Promise<AccountSlideshow> {
const res = this._slideshowModel.findOne()
return await res.exec()
}
}
Nestjs module:
@Module({
imports: [
MongooseModule.forFeature([
{ name: AccountSlideshow.name, schema: AccountSlideshowSchema },
]),
SequelizeModule.forFeature([Account, Item]),
],
providers: [
AccountSlideshowsRepository,
AccountsRepository,
AccountSlideService,
AccountHandler,
ItemsRepository,
],
controllers: [AccountSlideController],
})
export class AccountSlideModule {}
Service
@Injectable()
export class AccountSlideService {
constructor(
private readonly _slidesRepository: AccountSlideshowsRepository,
private readonly _accountHandler: AccountHandler,
) {}
public async getAccounts(offset: number): Promise<SlideDto> {
const settings = await this._slidesRepository.find()
console.log(settings) // works and gets plain JavaScript object from Mongo db
console.log(settings.limit2) - undefined
console.log(settings.position2) - undefined
}
}
I get data from Mongo db. There is not errors. But aliases don't work. Why? I search solutions in github, but didn't find its. What I do wrong?
Try to pass additional serialization options (toObject in your case):
