用于GraphQL（js）中的数字的枚举

Question

我想允许其中一个字段为1,2或3.我不确定如何在http://graphql.org/graphql-js/type/

中执行此操作

因为我需要做类似的事情：

var AgeType = new GraphQLEnumType({
  name: 'Age',
  values: {
    1: { value: 0 },
    2: { value: 1 },
    3: { value: 2 }
  }
});

这不起作用，因为密钥是一个数字......

Answer 1

It's not possible as described here: https://github.com/graphql/graphiql/issues/586

GraphQL require enum values to match [_A-Za-z][_0-9A-Za-z] RegExp

Enum variables have to start with a letter, so you will have to use String or Int type. In order to ensure that only 1,2 and 3 are passed, you may implement some kind of validation rules in the resolvers.
