Thanks for this information! Really, it is $_REQUEST as in PHP.
To yummyfajitas - your message is 50% trolling. Will you allow me to troll a little bit? I used django and scrapy few years ago and despite the fact it was better than PHP I would not even dare to compare it with Rails. Rails is that superior I don't even have words to explain it :D Conclusion: I'm not interested in Django and its bug because I love rails and wanna make it more secure anyways. Sorry, but Django is way less convinient to use. Security is another story though.
