field_every: FilterCondition # condition must be true for all nodes
field_some: FilterCondition # condition must be true for at least 1 node
field_none: FilterCondition # condition must be false for all nodes
field_is_null: Boolean # is the relation field null

Examples

# Get all Friends that are not in Group A and not in Group B and attend Event X

User(id: me){
  friends(filter:{AND: [
    {groups_every: {id_not: "group-a-id"}},
    {groups_every: {id_not: "group-b-id"}},
    {attended_some: {id: "event-x-id"}}
  ]})
}

# Get all Users that are in two groups A and B where the current user is also a member of A and B

allUsers(filter:{AND:[
  {groups_every: {id: "group-a-id", members_some: {id_neq: "current-user-id"}}},
  {groups_every: {id: "group-v-id", members_some: {id_neq: "current-user-id"}}}
]})

# All pictures where the author is not my friend.

allPictures(filter: { author { friends_every: { id_not: “my_id” } } })

# All pictures without author.

allPictures(filter: { author_is_null: true })

# All pictures with author.

allPictures(filter: { author_is_null: false })

Thanks Phil!

Your "missing" requirement is a little cumbersome to do with GraphQL, but is clearly possible as long as you accept a limit to the nesting. To get 5 levels you could make this query:

allItems(filter:{
  {items_every: {parent: "my-parent-id"}},
}){
  items {
    otherField
    items {
      otherField
      items {
        otherField
        items {
          otherField
        }
      }
    }
  }
}

@sorenbs, oh - I think that would actually work fine as I'd really just to want to go a few levels deep, then re-query if the user ended up digging deeper in the UI.

Super cool.
