You can also use Upsert Block. (There is a JSON version, which I believe it works only via HTTP/cURL):

upsert {
  query {
    q(func: eq(company_name, "Acme")) {
      v as uid #Find the company
    }
  }

  mutation {
    set {
      _:NewUser  <name> "Example name" .
      _:NewUser  <dgraph.type> "Person" .
      _:NewUser  <works_for> uid(v) .
    }
  }
}

See https://dgraph.io/docs/mutations/upsert-block/#sidebar

You have to remove the “company_name” from your users to not confuse it.

Liveloader has some options to do automatic upserts. But you have to use a flag to record the XIDs and also keep tracking XIDs(XIDs are external identifiers, in the case of Dgraph, Blank nodes will be considered XIDs during the load).
