There is no difference between ActiveRecord::Base.transaction and ModelName.transaction. Your models extend the ActiveRecord::Base class and inherit the transaction method. The implementation is thus exactly the same. The method is indeed transaction support as you can read in the API. Here you can also find some examples of usage of this method. |

You also need to check that your database engine actually supports transactions – for MySQL, for example, you should use the InnoDB type (which is the default in Rails anyway). Also worth mentioning: Rails, by default, does some transactions by itself if you’re using collection proxies (e.g. post.comments.create, etc.). |
