Question

我正在尝试使用CMake Error: install(EXPORT "MyLibTargets" ...) includes target "MyLib" which requires target "absl_base" that is not in the export set. CMake Error: install(EXPORT "MyLibTargets" ...) includes target "MyLib" which requires target "absl_strings" that is not in the export set. CMake Error: install(EXPORT "MyLibTargets" ...) includes target "MyLib" which requires target "absl_str_format" that is not in the export set.创建参数类型以通过GraphQL查询接受参数。我在说的type-graphql是MongoDB's native NodeJS driver documentation上的选项的属性。

sort

如您所见，简单类型很好，但是当涉及到排序对象之类的东西时，我不确定如何进行操作。

NestJS implements a date scalar like so：

@ArgsType()
export class FindAllArgs implements FindOneOptions {
    @Field(type => Int, { defaultValue: 0, description: 'Sets the limit of documents returned in the query.' })
    @Min(0)
    limit?: number;

    // This is where the custom sort would go about.
    @Field(type => SortScalar)
    sort?: sortScalar;

    @Field(type => Int, { defaultValue: 0, description: 'Set to skip N documents ahead in your query (useful for pagination).' })
    @Min(0)
    skip?: number;
}

即使在示例中，它也使用returnTypeFunction import { Scalar, CustomScalar } from '@nestjs/graphql'; import { Kind, ValueNode } from 'graphql'; @Scalar('Date', type => Date) export class DateScalar implements CustomScalar<number, Date> { description = 'Date custom scalar type'; parseValue(value: number): Date { return new Date(value); // value from the client } serialize(value: Date): number { return value.getTime(); // value sent to the client } parseLiteral(ast: ValueNode): Date { if (ast.kind === Kind.INT) { return new Date(ast.value); } return null; } }。我应该将@Scalar('Date', type => Date)替换为什么？我要为Date，parseValue和serialize输入什么？

您可以仅使用@InputType将对象嵌套在args中-您不需要标量，它们仅用于可序列化的事物，例如时间戳->数字，mongo id-> ObjectId实例等。< / p>

如何为MongoDB的collection.find（）函数中找到的MongoDB排序属性实现GraphQL标量？
