When I create @ApiProperty() in my Dto, it looks like this:
export class UpdateMeassageDto {
@ApiProperty()
message: {
hash: string;
created_at: Date;
updated_at: Date;
}
}
However, the result turns out to be empty. Here's what it looks like:
Consider creating a new Message type with the following properties:
export class Message{
@ApiProperty()
hash: string;
@ApiProperty()
created_at: Date;
@ApiProperty()
updated_at: Date;
}
Next, make sure to update your DTO to include the Message type like this:
export class UpdateMessageDto {
@ApiProperty()
message: Message
}
Here is a way to achieve it:
import { ApiProperty, getSchemaPath } from '@nestjs/swagger';
export class MessageDto {
@ApiProperty({
type: 'string',
example: 'hx1231',
})
hash: string;
@ApiProperty({
type: 'date',
example: '2021-08-04T19:39:00.829Z',
})
created_at: Date;
@ApiProperty({
type: 'string',
format: 'date-time',
example: '2021-08-04T19:39:00.829Z',
})
updated_at: Date;
}
export class UpdateMessageDto {
@ApiProperty({
type: 'array',
items: { $ref: getSchemaPath(MessageDto) },
})
message: MessageDto;
}
Each property requires an ApiProperty. The use of $ref allows for the reuse of one DTO within another DTO. Additionally, consider integrating class-validator into the DTOs for enhanced functionality.
