Creating a View filter for a CCK field

Question

I have created a custom filter which displays some select options to the user in order to filter a view. However, I am uncertain how to add this using the hook_views_data() hook, being that the table which the filter is being applied to is a CCK table called content_type_sm_mention.

Currently I have the following, which I am not sure is right. What is missing?

function smd_views_data()
{
    $data = array();
    $data['content_type_sm_mention']['sentiment'] = array(
      'title' => t('Sentiment'),
      'help' => t('Filter by mention sentiment.'),
      'real field' => 'field_mention_sentiment_value',
      'group' => t('Content'),
      'filter' => array(
        'handler' => 'views_handler_filter_sentiment',
      ),
    );
    return $data;
}
function smd_views_handlers() {
  return array(
    'info' => array(
      'path' => drupal_get_path('module', 'smd') . '/includes/views',
    ),
    'handlers' => array(
      'views_handler_filter_sentiment' => array(
        'parent' => 'views_handler_filter',
      ),
    ),
  );
}

Answer 1

To find out what is missing, implement hook_views_data_alter() and dsm($data) in the function to find the right path for your field.

Answer 2

I would look at content_views_data() in the cck module to see if you can figure out what it is returning.
