title: Retrieve the object ID in GraphQL
body: <p>I'd like to know whether it is possible to get the "original id" of an object as the result of the query. Whenever I make a request to the server, it returns the node "global identifier", something like <code>U29saWNpdGFjYW9UeXBlOjEzNTkxOA==</code> .  </p>
  
  <p>The query is similar to this one:  </p>
  
  <pre><code>{
    allPatients(active: true) {
      edges {
        cursor
        node {
          id
          state
          name
        }
      }
    }
  </code></pre>
  
  <p>and the return is:</p>
  
  <pre><code>{
    "data": {
        "edges": [
          {
            "cursor": "YXJyYXljb25uZWN0aW9uOjA=",
            "node": {
              "id": "U29saWNpdGFjYW9UeXBlOjEzNTkxOA==",
              "state": "ARI",
              "name": "Brad"
            }
          }
        ]
    }
  }
  </code></pre>
  
  <p>How can I get the "original" id of the object at the database level (e.g. '112') instead of that node unique identifier? </p>
  
  <p>ps.: I am using graphene-python and Relay on the server side.</p>
