How to update Arrays of Edges of the Parent Node?

Hi, I ran into a problem which is really making me crazy right now… :see_no_evil:

Let’s assume the following setup:

type User {
  id: ID!
  role: Role!
  tenantOf: [Organisation!]!
}

type Role {
  id: ID!
  type: RoleType!
}

enum RoleType {
  "ADMIN"
  "MEMBER"
}

type Organisation {
  id: ID!
  orgId: String! @id @search(by: [hash])
  tenants: [User!] @hasInverse(field: tenantOf)
}

A typical update mutation would then be:

mutation Update( $id: [ID!], $roleId: ID!, $orgs: [OrganisationRef!] ) {
  updateUser( input: { 
    filter: { id: $id },
    set: {
      tenantOf: $orgs
      role: {
        id: $roleId
      }
    } 
  }
}

where the variable $orgs has the following form:

orgs = [
  { orgId: "some_id_1" },
  { orgId: "some_id_2" }
]

If I run this mutation everything works fine and I can keep adding organisations to tenantOf. Unfortunately, if I want to remove one of the organisation references for the user, eg. by submitting

orgs = [
  { orgId: "some_id_1" }
]

it does not work - it keeps what ever was already in the array. I’ve researched a bit and the closest I could find was this post here, where using remove has been suggested within the mutation. So I have changed my mutation to

mutation Update( $id: [ID!], $roleId: ID!, $addOrgs: [OrganisationRef!], $removeOrgs: [OrganisationRef!] ) {
  updateUser( input: { 
    filter: { id: $id },
    remove: { tenantOf: $removeOrgs },
    set: {
      tenantOf: $orgs
      role: {
        id: $roleId
      }
    } 
  }
}

where I have set the organisation arrays to

addOrgs = [
  { orgId: "some_id_1" }
]

removeOrgs = [
  { orgId: "some_id_1" },
  { orgId: "some_id_2" }
]

Which is basically removing the old references and setting the new references - so I thought. Unfortunately, if I do so the field tenantOf gets completely removed from the user object! Am I doing this right? Thanks, any help appreciated!

Since you are both removing and adding to the same predicate, you have to use two mutation blocks, which can be done in a single operation.

mutation Update( $id: [ID!], $roleId: ID!, $addOrgs: [OrganisationRef!], $removeOrgs: [OrganisationRef!] ) {
  first: updateUser( input: { 
    filter: { id: $id },
    remove: { tenantOf: $removeOrgs },
    set: {
      role: {
        id: $roleId
      }
    }
  }) { numUids }
  second: updateUser( input: { 
    filter: { id: $id },
    set: {
      tenantOf: $orgs
    } 
  }) { numUids }
}
