Hi list, I''ve got some counter_caches in a model. When these get incremented - say on a page view - my updated_on column also gets updated. How can I conditionally not update updated_on if just these counter_cache columns change? The problem with that is that I am using acts_as_versioned which clones the record each time updated_on changes. I am successfully ignoring the counter_cache

Hi All, Rails newbie here trying to set up acts_as_versioned according to Chapter 14 in the Rails Recipies book.

Hi Rails List, I need some beta testers for my new site: http://www.smarkets.net. This list is literally the first group to see it, so be gentle. Smarkets is a prediction market for Amazon products. It takes Amazon products and turns them into a stock. The price of these "stocks" move based on the movement of its Amazon sales rank. If the sales rank goes up 10%, the price of the stock

Is there a method for retrieving the last SQL statement executed by ActiveRecord? I realize I can open the log file, but I''m looking for a programmatic way. -- Posted via http://www.ruby-forum.com/.

I''m trying now to do "sudo fixrbconfig" in the terminal, and I get this: /usr/lib/ruby/1.8/powerpc-darwin8.0/ruby.h does not exist.

I''m tinkering around with an old legacy table in SQL Server 2000. Ruby 1.8.4, most recent ADO.rb file from RubyForge, Rails 1.0 Here''s the model: class InventoryItem < ActiveRecord::Base set_table_name "[_SMDBA_].[_INVENTOR_]" set_primary_key "sequence" end Everything works fine.

I have a database with a couple of tables. One table called spares has foreign keys in another called equipment. When I create a new record, it is added to the spares table however the list action does not show all the columns in the table. It only shows those columns that are not foreign keys. I am using the default action generated by scaffold for list. Why is that so? Do i need to re-write my

Hi, I''ve started getting an error I can''t debug. The error doesn''t generate anything in my development log. A breakpoint set right at the beggining of the controller method does not get triggered. It happens on a form submission. I can make changes to the object model from with the console, but not on this form submission. I thought maybe it was routing, because I have

I am using a serialized attribute in one of my models The serialized data is in the form of an array. I want to have a text_tag for each element contained in my serialized attribute. How would I construct the text_tag? My model name is ''questions''. The serialized attribute is "answers" So I might have: <% form tag %> <% text_tag ''question'',

Quick question to see how I might re-sort an Activerecord data set. Let''s say I have this table: tablename: testscores | id | student | score | avg_for_year 1, steve, 85, 82 2, tom, 84, 92, 3, jim, 92, 95 In my controller, I have something like: t= Testscores.find(:all, :order => "score DESC", :limit => 2) ...where it would return the records for Jim and Steve.... My

I''m trying to get the id of the previous row prior to what would be input and then rename an uploaded image to that row number. So say the previous row was 19 and the image in that row was named 19.jpg, I''m wanting to name the next uploaded image as 20.jpg since the row that would be added then would be 20. Right now I''ve just got: @new_tutorial =

I''ve just about finished up work on a plugin similar to acts_as_taggable, but for comments instead which would allow you to attach comments (possibly even a threaded discussion if conbined with acts_as_tree) to any object. Is there anyone that would be interested in it? I don''t want to go throug the trouble of finding some way to distribute it unless I know that there is a

However, from time to time I switch some featured items off and mark others as featured. When this is done, I start getting dublicate numbers on the list and ordering starts getting problem... What would be the good approach to
