Fields public Control

You can use config.fields.*.public to control if a field needs to be removed from the results. If config.fields.*.public value is true or is not set, the field will be visible. If value is false, then the field will be removed (in any query, including inspection queries).

In the example below the privateData field will be available only for users with the role ROLE_ADMIN.

AnObject:
    type: object
    config:
        fields:
            id:
                type: "String!"
            privateData:
                type: "String"
                public: "@=service('security.authorization_checker').isGranted('ROLE_ADMIN')"

You can also use config.fieldsDefaultPublic to handle the setting globally on an object:

AnObject:
    type: object
    config:
        fieldsDefaultPublic: "@=service('my_service').isGranted(typeName, fieldName)"
        fields:
            id:
                type: "String!"
            privateData:
                type: "String"

Have you noticed typeName and fieldName here? These variables are always set to the current type name and current field name, meaning you can apply a per field public setting on all the fields with one line of yaml.
