ActiveRecord Love While We''re At It
I am working on and will be publicly showing ActiveRecord some love
around the time of the RubyConf*MI [1] in late August.
My main focus is getting AR to better handle inserts, updates and merges
when working large sets of data. It can improve improve performance by
400% to 600% in preliminary benchmarks.
I am coding this in a way so it can be patched to AR easily, and with
that in mind

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

ActiveRecord, using sql functions for some attributes
Hi.
I need to use functions INET_ATON, INET_NTOA for IP address retrieving.
Is it possible to make this transparently (without custom SQL for

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

has_many.count not accepting options hash
has_many.count does not seem to support an options hash like

Nasty pitfall: don''t use ^ and $ in validation regexes!
Let''s say you want to validate that an attribute contains only 2-10
lowercase characters, e.g. with validates_format_of. The appropriate
regex is obviously /^[a-z]{2,10}$/, right?
Wrong! Try it with "abc\nANYTHING YOU LIKE" - this is perfectly valid.
On the second look the reason is clear: ^ matches the start of a line, $
matches the end of a line. So as long as one line in

ActiveRecord, can it save more than one row at a time????
Hi,
I wonder if there is some fonctions which allow an
activeRecord to save more than one row at a time???
As I understand, when we create an object from
AC::Base, it represents one row of the table. So if I
want to save more than one row, I have to create the
object one by one and then save them one by one. If I
have 10, it is fine, but if I have more than 1000, so
it will a lot of time.... So

HOWTO? security based on data values
Hi!

I have a company table, employee table and transactions table.
1 company has many employees. Each employee performs many transactions.
Employees from different companies LOGIN to the system to record their
transactions. Employees can search on all transactions associated to
their companies (indirect relationship via employee),
