@test=Model.find(:all,:conditions=>"id=@someid")
thanks in advance

@test.nil? should work fine. It's probably not working because your find method is wrong. Try this instead:

@test = Model.find_by_id(@someid)

An alternative syntax is:

@test = Mode.find(@someid)

—Which will raise a RecordNotFound exception if the record doesn't exist.
