Return array object from resolver in nest js graphql Apollo play ground
问题
I need to return array of objects in the nest js graphql resolver. I have a mongodb schema which have multiple object array in the schema.
Supplier field is an object array which keep the relationship with Supplier schema with supplier_id.
I created (mutation) ingredient records successfully in my mongodb.
But when I am querying this record. My apollo server playground not allowing me to get the suppliers. I and successfully run the query to import ingredient_name and _id. My return type is ResultIngredientDto.
My graphql play ground only show
Can some one advice me what is the change I have to do to get the supplier object array. I have printed my query output it printing all the details. Thank you in advance.

@Schema()@ObjectType()export class Ingredient{@Field(() => ID)_id: string;@Prop()@Field({})ingredient_name: string;@Prop({type: mongoose.Types.Array})suppliers: [IngredientSupplier]}
Supplier field is an object array which keep the relationship with Supplier schema with supplier_id.
@Schema()export class IngredientSupplier {@Field(() => ID)_id: string;@Prop({ type: mongoose.Schema.Types.ObjectId, ref: 'Supplier' })@Field()supplier_id: string;@Prop({ required: true })@Field({})supplier_name: string@Prop({ nullable: true, default:0 })@Field({})unit_size: number;@Prop({ nullable: true, default: "" } )@Field({})unit_type: string;}
I created (mutation) ingredient records successfully in my mongodb.
{_id: new ObjectId("640746a5959b153fd91be321"),ingredient_name: 'test ingredient',suppliers: [{supplier_id: new ObjectId("63f8618d7f193739fac93d51"),supplier_name: 'test',unit_size: 112,unit_type: 'KG',_id: new ObjectId("640746a5959b153fd91be322")},{supplier_id: new ObjectId("63f880447f193739fac93d5d"),supplier_name: 'test11',unit_size: 114,unit_type: 'KG',_id: new ObjectId("640746a5959b153fd91be323")}],
But when I am querying this record. My apollo server playground not allowing me to get the suppliers. I and successfully run the query to import *** ingredient_name**** and *** _id ****. My return type is ResultIngredientDto.
@ObjectType()export class ResultIngredientDto {@Field(()=>ID)_id: string@Field()ingredient_name: stringsuppliers: suppliers[]}@ObjectType()export class suppliers {@Field(()=>ID)_id: string@Field()supplier_id: string@Field({})supplier_name: string@Field()unit_size: number@Field({})unit_type: string}
My graphql play ground only show
type ResultIngredientDto {_id: ID!ingredient_name: String!}
Can some one advice me what is the change I have to do to get the supplier object array. I have printed my query output it printing all the details. Thank you in advance.

得分: 1
suppliers 属性也需要 @Field 装饰器，这样你就可以添加
@Field(() => [suppliers])
英文:
suppliers property also needs @Field decorator so you can add
@Field(() => [suppliers])
