code changes when migrating from MyISAM to Innodb

Question

I am just wondering do I need to alter "ruby on rails" code when migrating from MyISAM to InnoDB.

I want to migrate to InnoDB and it's known that deadlock is something that may happen working with InnoDB, do I need somehow threat all my inserts and updates to DB.

By now, I used just standard methods of ActiveRecord without using transactions.

Thanks

From my point of view that should be possible without any problems. Migrate to InnoDB, run your tests and see if anything breaks. From my history of standard Rails projects I never ran into issues with deadlocks. But at the end it depends on the code you've written. There is no other way than trying it out.
