Provide views handler for votingapi joins.

Class

votingapi_views_handler_relationship

A custom join handler that connects arbitrary base tables to VotingAPI's data.

Code

function query() {

  // Figure out what base table this relationship brings to the party.
  $table_data = views_fetch_data($this->definition['base']);
  $def = $this->definition;
  $def['table'] = $this->definition['base'];
  $def['field'] = 'entity_id';
  $def['left_table'] = $this->table;
  $def['left_field'] = $this->field;
  if (!empty($this->options['required'])) {
    $def['type'] = 'INNER';
  }
  if (!empty($def['join_handler']) && class_exists($def['join_handler'])) {
    $join = new $def['join_handler']();
  }
  else {
    $join = new views_join();
  }

  // use a short alias for this:
  $alias = $def['table'] . '_' . $def['left_table'];
  if (!empty($this->options['votingapi'])) {
    foreach ($this->options['votingapi'] as $field => $value) {
      if (!empty($value)) {
        $def['extra'][] = array(
          'field' => $field,
          'value' => $value,

        );

          ' ',
          '-',
          '.',
        ), '_', $value);
      }
