How to determine the uid of a schema based on 3 other schemas?

Users Dgraph
5

I think what @Rahul has suggested should work, another way to write those queries would be as follows:

#We store cabinets from the device with a given inventory number in a variable `cabinets`

var(func: eq(inventory_number, 123)){
 cabinets as has_cabinets
}

#We store the relevant cabinet_keys from the `cabinets` 
var(func: uid(cabinets)){
 cabinet_keys as ~has_access
}

#Finally get client_ids which have access to the above keys.
GetUsers(func: uid(cabinet_keys)){
 ~has_keys{
    uid
    client_id
  }
}
