Is there any kind of transactional mechanism for Entities (D8), similar to SQL transactions, so that I could conveniently rollback in case of an error?

Hi, Vacho, when you say error

Hi, Vacho, when you say error do you mean as entering the wrong information or system error?

Thanks

Something like this but with Drupal 8 Entities. (Not query to db directly)

try {
$id = db_insert('example')
->fields(array(
'field1' => 'mystring',
))
->execute();
}
catch (Exception $e) {
$transaction->rollback();
watchdog_exception('my_type', $e);
}

The solution

I use this code solution:

   

    $database = \Drupal::database();
    $transaction = $database->startTransaction();
    $id_branch = null;
    try {
      if(empty($id_branch)) {
          throw new \Exception('Empty: Branch Entity id.');
      }
      $Branch = Entities::load($id_branch);
      $branch_address = $Branch->getAddress();

      for ($i = 0; $i < 8000; $i++) {
        $values = array(
          'entity' => $id_branch,
          'name' => 'Store ' . $i,
          'address' => $branch_address,
        );
        $Store = Store::create($values);
        $Store->save();
      }

    }
    catch (\Exception $e) {
      $transaction->rollback();
      watchdog_exception($e->getMessage(), $e);
      throw new \Exception(  $e->getMessage(), $e->getCode(), $e->getPrevious());
    }

There is actually transactional support in Drupal

I recently researched this info. It is part of the Drupal 7 (so I guess Drupal 8 also) API:
