Computed fields with the Prisma- & Relay-Plugins

[mkaradeniz]

Hi,

I have computed field that gets data from a relation (like in the user.profile.bio example here). That works fine, except when I want to get a node through the node query. Then it will only work if I explicitly also query the relation.

User

builder.prismaNode('User', {
  include: { groups: { select: { permissions: true } } },
  fields: t => ({
    permissions: t.stringList({
      resolve: user => {
        return uniq(user.groups.flatMap(group => group.permissions));
      },
    }),
    groups: t.relatedConnection('groups', { cursor: 'id', totalCount: true }),
  }),
  findUnique: id => ({ id }),
  id: {
    resolve: user => {
      return user.id;
    },
  },
});

UserGroup

builder.prismaNode('UserGroup', {
  fields: t => ({
    permissions: t.exposeStringList('permissions'),
    members: t.relatedConnection('members', { cursor: 'id', totalCount: true }),
  }),
  findUnique: id => ({ id }),
  id: { resolve: userGroup => userGroup.id },
  include: { members: true },
});

Queries

builder.queryType({
  fields: t => ({
    user: t.prismaField({
      type: 'User',
      nullable: true,
      args: {
        id: t.arg.id({ required: true }),
      },
      resolve: (query, root, args) => {
        return prismaClient.user.findUnique({
          ...query,
          rejectOnNotFound: true,
          where: { id: decodeGlobalID(args.id as string).id },
        });
      },
    }),
    users: t.prismaConnection({
      type: 'User',
      cursor: 'id',
      resolve: query => {
        return prismaClient.user.findMany({ ...query });
      },
    }),
  }),
});

These queries will work fine:

{
  users {
    edges {
      node {
        permissions
      }
    }
  }
}

{
  user(id: "VXNlcjpja3Z4eW01a3kwMDAwcmdnNWV1Z2ltYTVo") {
    permissions
  }
}

This query wont:

{
  node(id: "VXNlcjpja3Z4eW01a3kwMDAwcmdnNWV1Z2ltYTVo") {
    ... on User {
      permissions
    }
  }
}

Only when I also query for the relation, like so:

{
  node(id: "VXNlcjpja3Z4eW01a3kwMDAwcmdnNWV1Z2ltYTVo") {
    ... on User {
      permissions
      groups {
        totalCount
      }
    }
  }
}

will it work.

Is there a way I can build this, so the consumer doesn't have to include the relation in the query themselves?

This looks like a bug

I'll try to figure out what's going on, this is supposed to work as is

[hayes]

should be fixed in latest version

Yes, it works. Thank you very much!
