My DTO is
@Expose()
@IsNotEmpty()
@IsJSON({ each: true })
filesRole: string
filesRole is something like that: [{"file": "14125.png", "role": "bg"}, {"file": "x12.png", "role": "cover"}]
I want to validate role to be bg or cover.
You can try it with enum:
export enum Role {
bg = 'bg',
cover = 'cover',
}
@IsEnum(Role)
@Expose()
@IsNotEmpty()
@IsJSON({ each: true })
filesRole: Role
update your main DTO:
@Expose()
@IsNotEmpty()
@IsArray()
@ValidateNested({ each: true })
filesRole: Data[];
Data DTO:
export class Data {
@IsNotEmpty()
@IsString()
file: string;
@IsNotEmpty()
@IsString()
@IsIn(Object.values(roleEnum))
role: roleEnum;
}
roleEnum :
export enum roleEnum {
bg = 'bg',
cover = 'cover',
}
