RavenDb HTTP Patching - ravendb

Question

Trying to patch documents in RavenDb
$a = array('Patches' => array('pref_roles' => "1,2,3"),
'Key' => "Users/".$user_id,
'Method' => 'Patch'
);
{"Patches":{"pref_roles":"1,2,3"},"Key":"Users/4","Method":"Patch"}
$input = json_encode($input);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_CUSTOMREQUEST => 'POST',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POSTFIELDS => $input,
CURLOPT_URL => 'http://localhost:8080/databases/om/bulk_docs'
));
$resp = curl_exec($curl);
The patch is never getting through. Where am I going wrong?
Edit.
Added in the 'script'
$a = array('Patch' => array('Script' => 'this.natio = '.$natio.''),
'Key' => 'Users/'.$user_id,
'Method' => 'Patch');
I'm posting
CURLOPT_CUSTOMREQUEST => 'POST',
to this url :
CURLOPT_URL => 'http://localhost:8080/databases/om/bulk_docs'
With these error messages :

Played around a little to see if I could find the working solution but that didn't really work out.

Patch command data in this manner requires that you pass the actual operations.
See:
http://ravendb.net/docs/article-page/2.5/csharp/http-api/http-api-single
I suggest you'll go with Scripted patch, using EVAL.
$a = array('Patch' => ('Script' => "this.pref_roles = [1,2,3["),
'Key' => "Users/".$user_id,
'Method' => 'Patch'
);
