db

Today I decided to verify if Machinist could be a good replacement for Factory Girl. In our project, we have a big problem with Factory Girl: even if you tell her not to hit the database, using the Factory.build method, if an object has associations, these are saved on the DB. And this causes a huge slowdown in specs using factories. We’ve been using Factory Girl for nearly two years, and if we could find a way to stop him hitting the DB, we could really have a huge improvent in our test suite running time....

If you have a Rails rake task that somehow changes your DB data, but you want to be sure that the DB will be rolled back to its previous state after the rake task has completed, you can simply include this snippet right after your task definition: ActiveRecord::Base.connection.increment_open_transactions ActiveRecord::Base.connection.begin_db_transaction at_exit do ActiveRecord::Base.connection.rollback_db_transaction ActiveRecord::Base.connection.decrement_open_transactions end If you wonder where is this code coming from, it’s directly from the rails console code....
