如何使用代码优先的方法在graphql中创建更复杂的类型

Question

你好，我正在尝试为对象数组mutation创建field。代码如下：

import { Field, InputType } from '@nestjs/graphql';
type ChainToAddress = {
chain: string;
address: string;
};
@InputType()
export class CreateONSInput {
@Field()
ons: string;
@Field(type => [ChainToAddress])
chainAddressess: ChainToAddress;
}

当前正在抛出以下错误：

'ChainToAddress' only refers to a type, but is being used as a value here.

任何如何使其工作的想法，尝试过接口/类型，但不知何故无法管理它

您需要从嵌套接口中创建一个InputType/ObjectType才能使其工作。

@InputType()
class ChainToAddress {
@Field()
chain: string;
@Field()
address: string;
};
@InputType()
export class CreateONSInput {
@Field()
ons: string;
@Field(type => [ChainToAddress])
chainAddressess: ChainToAddress[];
}
