I'm having difficulties to find resources which explains how to cope with array of References to objects with TypeGraphQL and Typegoose.
Given the following models:
@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>[];
}
This is the error obtained for this code:
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?
What I want to achieve is to give possibility to BlogPost model to store an array of References/ObejctIDs of the BlogTag model.
I am new to this framework and I don't know if this is a good practice. How can I create an InputType which accepts an array of IDs?
You need to create a separate BlogTagInput with @InputType or check the FAQ for some handy yet "doatyourownrisk" workaround:
