what is the point of this relation thing? i am trying to follow learnapollo tutorial and it shows me to create type:

type user implements Node {
createdAt: ...
id: ...
posts: [Post]}

but i get response that relation is not set blah blah

Graphcool requires you to set the

@relation

attribute on the

posts

field, like documented here: https://www.graph.cool/docs/reference/schema/relations-goh5uthoc1/#relations-in-the-data-schema
