ActiveRecord instead of direct sql execution
Hi all,
I have 2 tables and a standard one-to-many association.
How do I substitute the following sql with ActiveRecord calls so that
it uses just one sql statement:
update geo_entities set terminal_id = 3 where id = 10 or id = 23
or id = 87;
Thank you!
Regards,

radiobuttons are weird in 1.2.x series
Hello all,
Run groupbox.rb example in any of the two alpha versions and
click the radiobutton in the upper right group box (those named Hilvesum 1,
Hilversum 2, etc). You''ll notice that once a radiobutton is checked,
it remains checked when some other radiobutton is checked.
What''s the reason?
Thank you.

Eager loading of association extensions
Hello all,
Is it possible to do eager loading of association extensions?
That is, the following code produces one SQL query:
cat = ProductCategory.find(:first, :include => :pricing_rules)
cat.pricing_rules
But if in ProductCategory I have an association extension like this:
has_many :pricing_rules do
def applicable()
find(:all).select(&:applicable?)
end

Newbie question - self.var OR @var in ActiveRecord
I started learning rails by following the agile way. It comes to the
point where it puzzles me.
class Puzzle < ActiveRecord::Base
# virtual var, not existing in the database
def var
@var
end
def var=(foo)
@var= foo
@var_in_database = @var + 1 # var_in_database exists in database
end
end
Then when I do a save of this model it does nothing. I know that if I

Dynamic JS updating / data-preloading using ajax
Hi all,
I''m building an application which uses mostly ajax to update the
sections of the page. Now I''ve come to some thoughts on how to make the
ajax-handling more efficient / less buggy.
Currently, when the page loads up, I start some "new Ajax.Updater"-stuff
to fill some sections with content from the db. I also registered
watchers which also start nearly the same

How to fire Ajax call from Form_for
I am learning Rails 3 and need some help on Ajax part.
I am trying to accomplish the following:
There is a textarea on the page which has a length of letters
constraint, say 100. Every time a symbol is typed there,a nearby label
tells you how many letters you have left.
I plan to use Ajax to do this.
I googled for a few hours and could not figure out how to do this.

Which version of Ubuntu to use with Rails
Hello,
This is a question for folks who are using Ubuntu to host your Rails
apps. Which version of Ubuntu do you use?
Do you use the ''Dapper'' release (6.0.6) perhaps due to the long term
support (LTS), or are you using the latest release ''Feisty'' (7.0.4)?
Or maybe a better way to ask the question is, is there a preferred
version of Ubuntu to use with Ruby

Updatable "datagrid" with ajax support? Is there any code/approach I can leverage?
Hi,
I want to have a page in my Ruby on Rails application that is like a
dynamic / updateable data grid. Like a matrix or spreadsheet segment
(x rows, y columns) which one can click in any of the cells and make
an update, which triggers some AJAX code to fire off the update, and
then the responses come back and update whatever else needs updating
based on this change.

Ajax.Request: onFailure vs. onException
Hello All,
I''m trying to capture the exception message that my server application
is providing in response to my Ajax.Request. However, I''m confused as
to when onFailure is fired vs. onException. The onException handler has
access to the javascript exception object and I''d understood that it was
only called when the dispatch fails. Not sure what exactly that means
