Change node author on node save with rules

Question

I have a very simple rule with Event "Before saving content" and Elements "Content is of type (page)" and would like the action to be something similar to "Change node author to UID X", which would be the UID I want.

I can't seem to be able to achieve that with the actions exposed. To test my rule I've been trying to display a message on the site when triggering the rule and it works just fine.

Any idea how to do that without having to write code?

This is on Drupal 7 (latest) with latest stable Rules version.

Answer 1

I think you can do this by adding a new action - "Fetch entity by ID", then selecting users and using that to update the node.

Answer 2

I have a suggestion for you for achieve this.(Its tested by myself).
create a new rule and in create node event(or every event you want ) , in action use Php(Execute custom PHP code)(make sure you php filter module installed).
and in there write this

 $mynode=node_load($node->nid);
 $mynode->uid='user_id_want';
 node_save($mynode);

-------------update------------
put your user id instead 'user_id_want'; as example

   $mynode=node_load($node->nid);
   $mynode->uid=20;
   node_save($mynode);
