How can I quickly re-save all users on my site?

Question

Very similar to this question except I need to save users, not nodes.

Use case: I added a field (single boolean) to a feature so that the field is added to user profiles. I then pushed the feature to my staging server. However, existing user accounts do not have the default field value for this field assigned. Re-saving each account fixes the problem, but there are 1000 users.

How can I quickly re-save all users on my site?

Answer 1

You can use the "Execute arbitrary PHP script" bulk operation in VBO and when you run it enter:

user_save($entity);

You could also run this PHP (you can do so by enabling the devel module and going to devel/php on your site):

set_time_limit(0);
$uids = db_query('SELECT uid FROM {users} WHERE uid != 0')->fetchCol();
$users = user_load_multiple($uids);
foreach ($users as $user) {
  user_save($user);
}

If you don't have many users you shouldn't need the time limit line.

Also, Clive mentions that field_attach_update is faster. To use that replace the user_save line with field_attach_update('user', $user)

Answer 2

rooby's answer is probably the easiest/quickest method but just to offer a code solution that can be used with VBO...

You can define your own action to save the user like this:

function MYMODULE_rules_action_info() {
  return array(
   'MYMODULE_update_user_account' => array(
     'label' => t('Save a user account'),
     'parameter' => array(
       'account' => array(
         'type' => 'user',
         'label' => t('User'),
       ),
     ),
     'group' => t('MODULENAME'),
   ),
 );
}

function MYMODULE_update_user_account($account) {
  user_save($account);
}

Once you've clerared the caches you should see your new action appear under VBO/rules and anywhere else actions are used.

Edit: It seems this might re-inventing the wheel somewhat if VBO will already let you do it natively, but it's a nice simple example of a rules action so I'll leave it here in case anyone needs it. Plus it removes the need for eval() to be used which is never a bad thing.
