"I am checking with params[:VARNAME].nil? and params[:VARNAME].blank?. My problem is that I use a variable VARNAME for some other purpose as well. How can I tell?" I mean, you COULD check the format of the VARNAME, but if it's two similar hashes, you're out of luck anyway. Best to rename one of them so there's no ambiguity, and then the problem goes away. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
