Speeding up ActiveRecord creation?
My completely empty model (no validation callbacks etc etc) takes an average of 0.05 seconds to create, at least according to Benchmark.realtime{200.times{Message.create(:from => "me@here.com", :message_type => ''email'', :subject => "hello", :body => "goodbye", :sent_at => Time.now)}}/200 That''s a little slower than

Go back to previous action
Hello all! I have two views (list_1 and list_2) that show a list of users in two different ways. In the views for these actions there is a link to edit a specific user properties (edit_user). That works fine, except that when I change the user I want to go back to the view that originated the request and not to the default list (list_1). Can anyone help me?

Firefox and IE performance with Rails App
In my rails application, certain computers were having huge problems. There were certain pages that were exceptionally slow, even to the point of timing out. Other computers did not have a problem. I finally found that Firefox was the difference. When using Firefox on those computers it works fine. The slow pages were typically posting a form with a couple hundred fields. This behavior was

How to DRY up validates_presence_of

HTML sanitizer
Hello! Does anybody know of a Ruby implementation of a HTML sanitizer that prevents the attacks described on the xss cheatsheet? (http://ha.ckers.org/xss.html) I checked out the version Jamis wrote (http://dev.rubyonrails.com/ticket/1277), but that only covers the very basic attacks. Anybody? Just figured I would ask before, before I reinvent the wheel.. Ciao! Florian
