Mongoose SubDocument

[hanza93]

Have you read the Contributing Guidelines?

Yes.

Hey, before the question here is a context: I'm using mongoose and I have 2 models (JobCard, Part) where JobCard has multiple Parts with different statuses for each Part, so I decided to go with subdocument, and here the problem started.

JobCard schema

@Schema({ timestamps: true })
export class JobCard extends Document {
  // ... some properties here
  @Prop({ type: [JobCardPartModel], default: [] })
  parts: JobCardPart[];
}
export const JobCardModel = SchemaFactory.createForClass(JobCard);

JobCardPart schema

@Schema({ timestamps: true })
export class JobCardPart extends Document {
  @Prop({ type: SchemaTypes.ObjectId, ref: 'Part', required: true })
  part!: Types.ObjectId;
}
export const JobCardPartModel = SchemaFactory.createForClass(JobCardPart);

and the DTOs are as follows

JobCard Dto

@ObjectType('JobCard')
@KeySet(['id'])
export class JobCardDto {
  @IDField(() => ID)
  id!: string;
  // some properties here
  @Field(() => [JobCardPartDto])
  parts: JobCardPartDto[];
}

JobCardPart Dto

@ObjectType('JobCardPart')
@KeySet(['id'])
export class JobCardPartDto {
  @IDField(() => ID)
  id!: string;

  @Field({ nullable: true })
  part: PartDto;
}

Part Dto

@ObjectType('Part')
@KeySet(['id'])
export class PartDto {
  @IDField(() => ID)
  id!: string;

  @Field()
  name: string;

  @Field()
  serialNumber!: string;
}

when I try to run this query

query GetOneJobCard {
  jobCard (id: "62a4592867fe1f9e232b3fbe") {
       id
       parts {
     	 part {
         id
      }
      status
      declinedReason
    }
  }
}

I'm getting this error ID cannot represent value: { type: \"Buffer\", data: [Array] }.

1. Am I doing it right?
2. Is there a better way to do it?

Thanks in advance.

This library doesn't work with mongoose v6. You need to use mongoose v5.

Or try the Typegoose version. Also the updated fork (look through the issues). This package has been dead for a while.

You made a mistake. Look at this https://doug-martin.github.io/nestjs-query/docs/persistence/mongoose/relations

@ObjectType('JobCard')
@KeySet(['id'])
@Relation('parts', () => JobCardPartDto, { disableRemove: true })
export class JobCardDto {
  @IDField(() => ID)
  id!: string;
}
