private method `scan' Error

[Chad Etzel]

Hi all,

I was playing with the simple_record (v2.0.5) gem today and created a
simple User object (extending SimpleRecord::Base) and some scaffolding
in Rails3 (w/ Ruby 1.8.7).

When calling the User.find(params[:id]) in the show method, I got the
following error:

NoMethodError in UsersController#show
private method `scan' called for 40:Fixnum

I tracked it down to the parse_condition_fields(conditions) method in
active_sdb.rb (line 632) - it seems like "conditions" is assumed to be
an Array, but in this case it was a String, and line 635 caused the
error - fields = conditions[0].scan(rx).

I changed the first conditional check from:
return nil unless conditions && conditions.present?
to:
return nil unless conditions && conditions.present? && conditions.is_a?
(Array)

and that fixed it. Otherwise, I had to call
Users.find(:first, :conditions => ["id = ?", params[:id]]) - which
seemed inelegant.

Anyway, has anyone else seen this, or am I doing something goofy and
this just happens to be a valid workaround? I'm quite new to ruby/
rails, so I could be doing something noobish...

Thanks,
-Chad
