[Rails] Re: What is the Ruby idiom for this?

See, I don't htink there IS an easier way -- just a Ruby-occluded way
called .find_by_sql(["select ..."])

A lot of this syntactic sugar really gets in the way. Rails is great,
as a web framework -- far superior to something like Struts. But in
the end, it;s back to JRuby, writing the back end in the C-like
syntax of Java, and avoiding Ruby and it's idioms, making use of Rails
this way.
