id字段上的GraphQL突变

Question

I have a GraphQL schema called Car Manufacturer which has two fields, id and name . What I am trying to accomplish via GraphiQL is to insert several data into the schema but I need to mutate both the mentioned fields.

Is there a way to insert a desired value on the id field?

Answer 1

Why you want to modify the id ? For using them as indexes? Like id: 1 , id: 2 an so on? If is that so, you should have something like globalIdField from graphql-relay in my opinion. Not mutate these ids yourself. For example:

import { GraphQLObjectType, GraphQLFloat } from 'graphql';
import { globalIdField } from 'graphql-relay';

export default new GraphQLObjectType({
  name: 'Car anufacturer',
  description: 'desc',
  fields: () => ({
    id: globalIdField('CarManufacturer'),
    title: {
      type: GraphQLString,
      resolve: async obj => obj.title,
    },
  }),
});

This way you will have unique ids and you can turn these ids on an ObjectId for use with MongoDB for example.

If you want to change this values for whatever other reason, you have to create Mutations just like @arian said

I hope that I helped you someway :)
