问题 I have a class Plan in which there is a list of Activity . The Activity class has a reference to a single Plan . Hence there is a OneToMany relationship like this: @Entity public class Plan { @OneToMany(mappedBy = "Plan") private List<Activity> activities; } @Entity public class Activity { @ManyToOne @JoinColumn(name= "PLAN_ID") private Plan plan; } I need to convert them to DTOs to be sent to presentation layer. So I have an assembler class to simply convert domain objects to POJO. public

问题 I want to assign the result of a query to a DTO object. The DTO looks like this: @Getter @Setter @NoArgsConstructor public class Metric { private int share; private int shareholder; public Metric(int share, int shareholder) { this.share = share; this.shareholder = shareholder; } } And the query looks like the following: @RepositoryRestResource(collectionResourceRel = "shareholders", path = "shareholders") public interface ShareholderRepository extends PagingAndSortingRepository<Shareholder,

问题 I am using Nest.Js with TypeORM and I want to hash my password before persisting into the DB. I tried using the event decorator @BeforeInsert() however it wasn't working for me but later I found that it was not working because I was taking an DTO as an input. user.controller.ts @Post() async create(@Body() data: CreateUserDto, @Res() res) { // if user already exist const isUserExist = await this.service.findByEmail(data.email); if (isUserExist) { throw new BadRequestException('Email already

问题 First off - I know, it might seem like the same question has been asked a million times. However, this is related rather to DTOs, not entities nor missing cascades. If I create an entity myself and save it, everything is fine. The problem occurs when I create a DTO, convert it with ModelMapper and then try to save the converted entity. If you look at the test class, the first test(saveCarByEntity) passes but the second(saveCarByDto) one produces the error. Every class connected can be seen

问题 TLNR: I was trying to test DTO validation in the controller spec instead of in e2e specs, which are precisely crafted for that. McDoniel's answer pointed me to the right direction. I develop a NestJS entrypoint, looking like that: @Post() async doStuff(@Body() dto: MyDto): Promise<string> { // some code... } I use class-validator so that when my API receives a request, the payload is parsed and turned into a MyDto object, and validations present as annotations in MyDto class are performed.

问题 I need to create some DTO classes to transport our business objects across WCF. Since these are just bags of data with no functionality, is there any reason I can't just use fields, or is there some good reason to expose them properly as properties? //fields [DataContract] class CustomerDTO { [DataMember] public int Id; [DataMember] public string Name; } //or properties? [DataContract] class CustomerDTO { [DataMember] public int Id { get; set; } [DataMember] public string Name { get; set; } }
