Question about Active Record

Rails
1

Good Morning,

I’m an student of Computer Engineering from Simn Bolvar University, in
Caracas Venezuela. I’m working in my thesis about ORM and their
“respectfulness” on databases. In order to have a better understanding
of
the Ruby on Rails ORM, I’m wondering where do I can read about the
low-level methods of the ORM, or what module can I study to see that.
Why
I’m looking for is something like how ActiveRecords translates for
example
an search on SQL.

In advance, thank you very much.

Sounds like you want to be looking at the arel gem and at
ActiveRecord::Relation

Fred thanks for the response, a friend and I did some tests and found
some
useful info. Altough we’re now wondering what would it happen if we
decide
not to work with ActiveRecord on RoR, what features of the framework
we’re
going to lose?

You’d lose the persistence layer, unless you replace it with another one
(datamapper, mongoid etc.)
