title: Drupal node reference
body: <p>I am using two content types - test_parent &amp; test_child
  In test_child there are two fields, both of type datetime
  And in test_parent there are two fields, week_no &amp; 7 node references</p>
  
  <p>I am using node_save to save a new node.
  After saving a node of parent type, and then saving the node of child type, i want to update the node it into the parent type.</p>
  
  <p>I have completed creation of both nodes from code, and also i am able to update nid in parent type from code.</p>
  
  <p>The problem is, the change in db is getting reflected in db but not on drupal node view.
  Even if i edit the node from drupal, it's showing -none- selected in node reference.</p>
  
  <p>Please help.</p>
