Hi there,
Why does the following query...
ser = ''ser''
@user = (''U''+ser).find(:first)
...not equal this one:
@user = User.find(:first)
?
What needs to be done so it will work?
Thanks for your help!
Tom

Great - thanks! -- Posted via http://www.ruby-forum.com/.
which can get you to some cool code like: @object = params[:controller].singularize.camelcase.constantize.find(params[:id]) -- Posted via http://www.ruby-forum.com/.
1 question back, though: What if need to end up having... @user = User.find(:first) ...based on a case like this: @u = ''@u'' ser = ''ser'' Is there something as "objectize"? :-) How would the following need to be corrected? (@u+ser).objectize = User.find(:first) Thanks for your help! Tom -- Posted via http://www.ruby-forum.com/.
