I have 2 entities i.e Customer, Orders with one to many relationship. A customer can have multiple orders and an order can be owned by only one customer. I am creating an api to create order that is a POST
api.
order.controller.ts
@Post()
async createOrder(@Body() order: CreateOrderDto) {
const newOrder = await this.orderService.createOrder(order);
return newOrder;
}
order.service.ts
async createOrder(order: IOrder) {
const newOrder = this.orderRepository.create(order);
await this.orderRepository.save(newOrder);
return newOrder;
}
create-order.dto.ts
export class CreateOrderDto {
@IsString()
@IsNotEmpty()
@Length(5, 400)
public description: string;
@IsNotEmpty()
@IsNumber()
@IsPositive()
public amount: number;
@IsNotEmpty()
@IsString()
public paymentMethod: string;
@IsOptional()
@IsString()
public customizeName: string;
@IsOptional()
@IsString()
public weight: string;
@IsNotEmpty()
public customer: ICustomer;
@IsNotEmpty()
@IsArray()
public products: Array<IProduct>;
}
I am sending this json from postman

"description": "Customize blue color vaaulid with picture printing",
