Limit Fivestar for node author only

Question

I have a content type called Task, where I add tasks. After task being completed, I would like the node author to rate his satisfaction using Fivestar field.

While viewing the node (not in edit mode), how to enable voting on this satisfaction rating field by node author only on his task but others can't vote, they can see his/her vote.

Here is an alternative answer, specific to the case where the voting happens on the frontend (using the "rated while viewing" widget).

1. Under "Manage Fields", configure your rating/fivestar field to use the widget "Stars (rated while viewing)". You also must configure the options:

   • Allow users to vote on their own content: This must be on
   • Allow users to cancel their ratings: This is optional
   • Allow users to re-vote on already voted content: This should be off

2. Under "Manage Display", configure your rating/fivestar field to disallow voting via AJAX:

   • Allow voting on the entity: This must be off, we will modify this dynamically

3. In a custom module, you should implement the following hook. It will activate the "Allow voting on the entity" only for the author of the node.

   /**
    * Implementation of hook_field_display_ENTITY_TYPE_alter().
    */
   function yourmodule_field_display_node_alter(&$info) {
     if($info['type'] == 'fivestar_formatter_default') {
       global $user;
       $node = menu_get_object('node');
       if($node && $user->uid == $node->uid) {
         $info['settings']['expose'] = TRUE;
       }
     }
   }
   

This configuration+code delivered the result you wanted on my sandbox instance, hope it works for you!

Here are the steps you need to allow only the node author to rate the node.

1. For the Task content type, change the role permissions so that only the authenticated users (or whichever role you want to allow to complete and rate Tasks) have the "Edit own content" permission.
2. Under "Manage Fields" for the Task content-type, configure your rating/fivestar field to use the widget "Stars (rated while editing)". Now, only the node's autor can edit and rate a Task node. The vote will still be visible to other users.

Hope this helps!
