Rules support

Dear all,

I was trying to use Rules to create activities that would then be reported by Heartbeat.

Goal: Whenever a user edits the (custom) text field 'status' of my Profile2 user profile, I want a status update like 'Username changed his/her status to I am happy' to appear in the Heartbeat stream.

For this, I performed the following steps:

1. I created a Heartbeat template 'Status update' at admin/structure/heartbeat/templates. The template's content is !username has changed his/her status to !status.
2. I created a rule 'Publish status updates to activity stream' at admin/config/workflow/rules with the following properties:
   • Event: After updating an existing profile
   • Conditions: Element has field
     Parameter: Entity: [profile2], Field: field_status
   • Actions: Log activity for Status update
     Parameter: Entity ID: <?php return 0; ?>, User ID: [profile2:user:uid], Entity target ID: <?php return 0; ?>, User target ID: [profile2:user:uid], Message ID: Status update, !username: [profile2:user:name], !status: [profile2:field-status]

Given this, I edited my own status and ran into the following error:

Notice: Object of class EntityValueWrapper could not be converted to int in rules_action_heartbeat_activity_log() (line 40 of /var/customers/forum/Server/sites/all/modules/heartbeat/modules/heartbeat_rules/heartbeat_rules.inc).

I took a look at heartbeat_rules.inc and after some debugging changed:

function rules_action_heartbeat_activity_log() {
  // ...
  foreach ($arguments as $key => $value) {
    if (isset($template->variables[$key])) {
      $variables['variables'][$key] = $value;
    }
    else {
      $variables[$key] = $value;
    }
    if (in_array($key, array('nid', 'uid', 'nid_target', 'uid_target'))) {
      $variables[$key] = (int) $variables[$key];
    }
  }
  // ...
}

to

function rules_action_heartbeat_activity_log() {
  // ...
  foreach ($arguments as $key => $value) {
    if ($value instanceof EntityValueWrapper) { // NEW
      $value = $value->value(); // NEW
    } // NEW
    if (isset($template->variables[$key])) {
      $variables['variables'][$key] = $value;
    }
    else {
      $variables[$key] = $value;
    }
    if (in_array($key, array('nid', 'uid', 'nid_target', 'uid_target'))) {
      $variables[$key] = (int) $variables[$key];
    }
  }
  // ...
}

I am, however, not sure whether this is how it should be. Could somebody with more Heartbeat experience (which does not necessarily mean somebody older ;-)) take a look at this?

Best,
Kaspar
