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?
Best regards,
Hugo

ad-hoc query
How do you run an ad-hoc query that does not belong in any model? I
thought it was something like ActiveRecord::connection.find("my
query..."), but I can''t seem to find the documentation on it. I know
I''ve seen it somewhere before, though.
thanks,
Jeff

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.

How to DRY up validates_presence_of
Given the case of validating the presence of an attribute and then
performing other tests on said attribute, how do you go about not having
to check for nil in the other tests?
Example:
validates_presence_of :start_date, :end_date
validate :validate_start_date_before_end_date
def validate_start_date_before_end_date
# without this check an exception will be thrown on access to the

Warnings printed to console causes error if console closed on Linux
I had a statement that was generating a warning about parenthesise
argument for future version. The interesting thing was it would crash
the page with an input/output error on my production linux server, but
worked fine in webbrick/windows. I finally tracked it down to it crashed
when trying to print the warning to the console. If I kept the terminal

There are potentially thousands of results. This takes ages to

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!

XSS prevention with Rails
Hi!
I wanna take a stab at implementing better XSS prevention for Rails.
This time for real =)
I''m wondering what would be the better way, clean everything up with
tidy first and then do the rest with regexp or regexp all the way?
Anybody done this before?

DRYing - similar named fields, etc.
I''m sorry - just couldn''t come up with a subject that describes the
problem :(
Anyway, this is my problem. I have a long list of fields that need to
be displayed when a ''show'' is requested on the controller. I''m now
doing the list.rhtml and looking for a DRY way to do the following.
For each data item, I have 2 fields - one is the item name, the
