Hopefully this would help :

> **[ActiveRecord::Base](https://api.rubyonrails.org/classes/ActiveRecord/Base.html)**

> Active Record Active Record objects don't specify their attributes directly, but rather infer them from the table definition with which they're linked.

Another good link:

> Active Record Transactions Transactions are protective blocks where SQL statements are only permanent if they can all succeed as one atomic action.

It is also good to know that the “save” and “destroy” methods already  
use transactions to ensure before and after callbacks.
