Hi,

I'm attempting to build a set of conditions dynamically using an array as suggested in the first answer here: http://stackoverflow.com/questions/1658990/one-or-more-params-in-model-find-conditions-with-ruby-on-rails. However I seem to be doing something incorrectly and I'm not sure if what I'm trying is fundamentally unsound or if I'm simply botching my syntax.

I'm simplifying down to a single condition here to try to illustrate the issue as I've tried to built a simple Proof of concept along these lines before layering on the 5 different condition styles I'm contending with.

This works:

excluded.push 12
excluded.push 30
@allsites = Site.all(:conditions => ["id not in (?)", excluded])

This results in a private method 'scan' called error:

excluded.push 12
excluded.push 30
conditionsSet << ["id not in (?)", excluded]
@allsites = Site.all(:conditions => conditionsSet)

Thanks for any advice. I wasn't sure if the proper thing was to put this as a followup item to the related question/answers I noted at the top. Since I've got a problem not an answer. If there is a better way to post this related to the existing post please let me know.
