You are viewing docs for silverstripe/graphql 4.x. If you are using 3.x, documentation can be found in the GitHub repository

Nested type definitions

For readability and ergonomics, you can take advantage of nested type definitions. Let's imagine we have a Blog and we want to expose Author and Categories, but while we're at it, we want to specify what fields they should have.

# app/_graphql/models.yml
App\PageType\Blog:
  fields:
    title: true
    author:
      fields:
        firstName: true
        surname: true
        email: true
    categories:
      fields: '*'

Alternatively, we could flatten that out:

# app/_graphql/models.yml
App\PageType\Blog:
  fields:
    title: true
    author: true
    categories: true
SilverStripe\Security\Member:
  fields:
    firstName: true
    surname: true
    email: true
App\Model\BlogCategory:
  fields: '*'

You cannot define operations on nested types. They only accept fields.
