Is there a compelling reason to prefer reliance on the params hash vs.
the same info stored in a session hash? So, for example, params[:id] =
@loan vs. session[:loan_id] = @loan.id? It matters because I can make
prettier urls if I store certain uniquely identifying model attributes
as session variables.
The drawback I can think of in preferring session variables to the
params hash is that a user cannot be guaranteed to recover via the
same url the same model instance under the session-preferred approach,
because the session variable may have changed.
Thanks for any comment,
