我很难找到解释如何使用 TypeGraphQL 和 Typegoose 处理对对象的引用数组的资源。
给定以下模型:
@ObjectType({description: "Blog Tag Model"})
export class BlogTag {
@Field(() => ID)
id: number;
@Field(_type => String)
@Property({required: true, unique: true, index: true, trim: true })
name: string;
}
@ObjectType({ description: "Blog post model" })
export class BlogPost {
@Field(() => ID)
id: number;
@Field()
@Property({required: true})
title: string;
@Field()
@Property({required: true})
description: string;
@Field(_type => [BlogTag], {nullable: false})
@Property({default: [], ref: 'BlogTag'})
tags: Ref<BlogTag>[];
}
@InputType({ description: "Blog post input" })
export class BlogPostInput implements Partial<BlogPost>{
@Field()
@Property()
title: string;
@Field()
@Property()
description: string;
// Here is the problem / question
@Field(_type => [BlogTag], {nullable: false})
@Property({ref: BlogTag})
tags: Ref<BlogTag>[];
}
这是此代码获得的错误:
CannotDetermineGraphQLTypeError: Cannot determine GraphQL input type for 'tags' of 'BlogPostInput' class. Is the value, that is used as its TS type or explicit type, decorated with
a proper decorator or is it a proper input value?
我想要实现的是为BlogPost
模型提供存储模型的引用/对象 ID 数组的可能性BlogTag
。
我是这个框架的新手,我不知道这是否是一个好习惯。如何创建一个接受 ID 数组的 InputType?
