Graphcool generates mutations for creating nodes with relationships but I can't figure out how to use them. The generated mutation for my

user hasMany wishes

is

addToUserWishes(userUserId: ID!, wishesWishId: ID!): AddToUserWishesPayload

but how does that work? Do I then run the

createWish

mutation nested within the

addToUserWishes

mutation? How do I go about establishing that connection when my user creates a new wish?
