我只想创建 ObjectType 类,它只是由 TranslationImportBase 在 nestjs 中使用 graphql 创建的 PickType。
@Entity()
@ObjectType({ isAbstract: true })
export class TranslationImportBase {
@Field(() => Int)
@PrimaryGeneratedColumn({ type: 'int', name: 'id' })
id: number;
@Field(() => User, { nullable: true })
@ManyToOne(() => User)
importedBy: User;
@Field(() => GraphQLISODateTime, { nullable: true })
@Column({ type: 'datetime' })
imported: Date;
@Field(() => String)
@Column('varchar', { length: 20, nullable: true })
sourceLanguage: string;
@Field(() => String)
@Column('varchar', { length: 20, nullable: true })
targetLanguage: string;
}
export class LastTranslationsImport
extends PickType(
TranslationImportBase,
['imported', 'importedBy', 'targetLanguage', 'sourceLanguage'],
)
{}
在这种情况下,我遇到了错误:
Error: Cannot determine a GraphQL output type for the "lastTranslationImport". Make sure your class is decorated with an appropriate decorator
但是当我添加 @ObjectType() 装饰器时,我收到了这个错误:
GraphQLError: Type LastTranslationsImport must define one or more fields
所以我有点卡住了。您知道如何正确定义 LastTranslationsImport
吗?
