Hi, I''m trying to execute something like this method in a model: def self.sql_for_rankings() sql = "SET @counter:=0;" sql << " SET @counter:=0; SELECT *, @counter:=@counter+1 AS rank FROM testscores. " find_by_sql(sql) end Where the new rank column is a kind of autoincrementer inside of

Hi, I''m completely new to all of this. Not even certain this is an appropriate forum for an installation question. I''m just about to plunk down some money to get a virtual server. In looking over the list of isp''s elsewhere on this site, goDaddy isn''t mentioned - probably because they don''t offer rails as a standard distribution. There are some

Hi, I seem to remember seeing the equivalent of saving only if all attributes are different. I can''t seem to find that now in the API or the agile book. I''m using the acts_as_versioned and only want to save if the input is different. Thanks, Steve http://www.smarkets.net -------------- next part -------------- An HTML attachment was scrubbed...

Hi list, I have a list of tags. I want to be able to click on a tag and have that tag name populate an input field. I think delicious used to allow you to click on existing links to tag your bookmark similar to this (moving instead to auto_complete). My guess is the code looks something like this.... <form> <input type="text" name="all" id="discover"

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

Hi, I''m using textilize with redcloth 3.0.4. Everything works best except that paragraphs are not translated as an HTML paragraph When I write something like: *first paragraph* second paragraph the output is without paragraph: *first paragraph* second paragraph Any help??? Thanks Jörg

Hi All - I notice that most of the Rails team are using Mac OS X and TextMate for Ruby development. I too am working on Mac OS X and trying TextMate and (shudder?) EMacs. I was wondering about version control. Are folks using Subversion? If so, are they using a graphical client? Which one do they recommend? Yours, Jordan -- Posted via http://www.ruby-forum.com/.

Anyone know of a good (fast) way to encrypt/decrypt uploaded files in RoR? I''ve seen this project: http://ezcrypto.rubyforge.org/ but it only seems to encrypt strings and such. I need to encrypt files once they are uploaded, then decrypt them when they request the file back. Any ideas? Thanks, Mark -- Posted via http://www.ruby-forum.com/.

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

Hi all, I''m working on a Rails application. In this application I retrieve a list of ''brands'' using a method somewhere defined in my controller: private def get_brands @brands = Product.find_by_sql("select distinct brand from products"); end However, I display this information in a listbox in the template for my controller. This means @brands

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'',

Using lighttpd + fcgi to power a site. When no one has accessed it in a while, the first visit to the page takes a while to load up. Then subsequent visits are fairly fast. Any ideas on how to fix it?

I''ve tried a bunch of things trying to get ruby/apache2 and php working together. I looked over my earlier post and followed the instructions on ezra''s website to install lighttpd on debian. I''ve gotten really far but I think there is one bit missing: 1. I got apache2 and php working together 2. I got lighttpd working on port 3000 and my rails app launches ok

Well, my entry for the 24-hour Rails Day competition is here: http://yubnub.org . It''s a web app called YubNub that implements the grandiose idea of a "command line for the Web OS". Type "gim porsche 911" to do a Google Image search for Porsche 911 cars. Type "random 1000" for a random number between 1 and 1000. Type "tts David Heinemeier Hansson is

(Nuby to Ruby and Rails...) I''ve implemented security using the login generator in a simple app so that I have a user table, a roles table, and a join between them (roles_users). All works as expected. I now need to check if a user has a specific role, but my approach is off somehow. Here''s what I''ve tried thusfar: user_roles = @session[:user].roles

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

Hi, I need a fresh set of eyes to look at this bit of controller code and tell me why I might be getting an error message: lookup = Profit.find(:all, :conditions => [ "user_id = ? AND product_id = ?", uid, pid]) unless lookup.empty? if (lookup.updated_on > 360.minutes.ago) return end end If lookup is empty, then I
