Class

DataTable

Manages data access and manipulation for a single data table. Use data_create_table() or data_get_table() to instantiate an object from this class.

Code

public function create($table_schema) {

  // Only create the table if it is not defined as data table AND it does not
  // physically exist.
  if (!_data_load_table($this->name, TRUE) && !db_table_exists($this->name)) {

    // Create table.
    db_create_table($ret, $this->name, $table_schema);
    if ($ret[0]['success'] != 1) {
      drupal_set_message(t('Error creating table.'), 'error');
      return FALSE;
    }

    // If schema module is enabled, inspect and read back to make
    // sure our schema information is up to date.
    // @todo: this is slow, maybe we need to make this an explicit method
    // on DataTable.
    if (module_exists('schema')) {

    $this->table_schema = $table_schema;
    $this->export_type = EXPORT_IN_DATABASE;

    // Save table information.
    // Set export_type - needs to be defined so that schema information is being passed on
    // to Drupal by data_schema_alter().
    // @todo: refactor ->update() to ->save() and use ->save().
    $table = array(
      'name' => $this->name,
      'table_schema' => $this->table_schema,

      views_invalidate_cache();
    }

    // data ui exposes path to a new default view.
