access properties of relations?

[stephen-dahl]

given the schema
(Cart) --[hasItem]->(Item)
how would you get the quantity property from the relation hasItem?

type Cart {
    items: [Item]
    ...
}
type Item {
    name: String!
    description: String!
    price: Float!
    ...
}
type hasItem {
   quantity: Int!
}

Hey @stephen-dahl we've recently added better relationship type support in v1.0.x. For your example, try

type Cart {
  items: [CartItems]
  
}

type Item {
  name: String!
  description: String!
  price: Float!
}

type CartItems @relation(name:"HAS_ITEM") {
  from: Cart
  to: Item
  quantity: Int!
}

If you contruct your schema using makeAugmentedSchema (or augmentSchema) you'll see autogenerated Query and Mutation types for basic CRUD. In your case to access quantity your GraphQL query would look something like:

Cart {
  items {
    quantity
    Item {
      name
      description
     }
  }
}

Please give it a try and let us know how it works!
