[英]How to define ID type in Nestjs + Graphql Mutation Args?
I am searching one things.我正在寻找一件事。 Actually I am building a
graphql api
with nestjs
.实际上我正在用
nestjs
构建一个graphql api
。 Here I want to ID type in @Args
Input.在这里,我想在
@Args
输入中输入 ID。
Here is example-这是示例-
import { Resolver, Mutation, Query, Args, Context, ID } from "@nestjs/graphql";
@Mutation(() => SuccessInfo, { name: "addSubCategory" })
addSub(
@Args("id") id: ID // Here is type ID
) {
console.log(id);
}
Here I import ID
type from @nestjs/graphql
.在这里,我从
@nestjs/graphql
导入ID
类型。 And add type as id
.并将类型添加为
id
。 But I getting one error like-但是我遇到了一个错误,例如-
'ID' refers to a value, but is being used as a type here. Did you mean 'typeof ID'?
Parameter 'id' of public method from exported class has or is using private name 'ID'
Then I try to add typeof ID
.然后我尝试添加
typeof ID
。
import { Resolver, Mutation, Query, Args, Context, ID } from "@nestjs/graphql";
@Mutation(() => SuccessInfo, { name: "addSubCategory" })
addSub(
@Args("id") id: typeof ID // Here is type ID
) {
console.log(id);
}
Then It solve typescript
error.然后它解决
typescript
错误。 But I also get error in console when starting the server-但是在启动服务器时我也会在控制台中遇到错误-
Undefined type error. Make sure you are providing an explicit type for the "addSub"
But When I give String
.但是当我给
String
。 It works perfectly.它完美地工作。 But I need to add
ID
.但我需要添加
ID
。
import { Resolver, Mutation, Query, Args, Context, ID } from "@nestjs/graphql";
@Mutation(() => SuccessInfo, { name: "addSubCategory" })
addSub(
@Args("id") id: String // Here is type ID
) {
console.log(id);
}
Here I need ID type How can I define ID type from here.这里我需要 ID 类型 如何从这里定义 ID 类型。
Here is the correct way to do it:这是正确的方法:
import { Resolver, Mutation, Query, Args, Context, ID } from "@nestjs/graphql";
@Mutation(() => SuccessInfo, { name: "addSubCategory" })
addSub(
@Args("id", { type: () => ID } ) id: string // Notice it's string not String
) {
console.log(id);
return { status: true } // return anything here which matches the SuccessInfo type
}
