Hi all, I have a little function called format_price(price) that simply formats the argument as a dollar sign, dollar amount, dot and penny amount. Then, in a .rhtml file, I could do this: <%= format_price(item.unit_price * item.quantity) %> But where do I put the format_price() function definition? The app couldn''t find it in app/controllers/application.rb. Where do I put it

Hi all, On the rails list I''ve seen that it''s hard to integrate Rails with Apache (especially apache2), that it''s hard to change the default port (3000), and that Apache runs Rails stuff slowly. Is it reasonable to run Rails stuff on Webrick while simultaneously running other stuff on Apache? How does one simultaneously run two rails applications on Webrick, when

Hi all, In re-doing the very first Hello World in the Agile Rails WEb Dev book, I continuously got blank pages, no matter what URL I put in, except when I put http://localhost:3000/ After eliminating everything else, I switched from Mozilla to Konqueror, and the symptom went away. I tried clearing cache on Mozilla, but that didn''t bring it back. I copied and pasted the URL from

I am creating an application to run a fishing tournament (see http:// www.ruby-forum.com/topic/51209 for a little background) Now I am running into an issue trying to calculate a leader board. each participate can enter multiple fish but only the largest fish per a given species counts towards the overall score. My entries table looks like this:

Today we finally opened the doors to "Street Easy" (http:// www.streeteasy.com/), a Real Estate Research Site for New York City. It was built by two guys in three months. It doesn''t have tags, but it has google maps. It rides two bubbles at the same time. It''s like road kill: the price tags will shock you, but you won''t be able to stop browsing around.

Hi all, Apparently rails didn''t install correctly on my Mandrake 10.0 system. ================================= [slitt@mydesk work]$ rails demo /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:204:in `report_activate_error'': Could not find RubyGem rails (> 0) (Gem::LoadError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:141:in `activate'' from

I''m new to Ruby and RoR but excited to learn what I can do with RoR; I have Pickaxe second edition and want to get "Agile Web Development with Rails" but I''m aware that the book was published some while before RoR version 1.0 was released. Has a lot changed since then, and would I therefore be advised to wait for a second edition of AWDwR? Many thanks in advance

Is it still true that in order for a Linux hosted Samba server to have NT ACL support, the Linux box must have an ACL aware file system such as XFS or Andreas Gruenbacher's kernel patch ("POSIX ACL")? I read this in chapter 4 of "Teach Yourself Samba in 24 Hours". In the time since that book was written, has an easier method been developed, or has a

I''m interested in the idea of using AJAX and SVG to create a simple diagram editor. It seems like Rails might be able to support this sort of thing, so I thought I''d ask if anyone is doing anything in this direction. -r -- Technical editing and writing, programming, and web development: http://www.cfcl.com/rdm/resume.html Contact information: rdm@cfcl.com, +1 650-873-7841

Hi, I have a little conundrum. I want to bitcode link a whole program, but I've run into a roadblock. During code generation on a processor that doesn't support e.g. floating point, a floating point mul is turned into a function call. This isn't known at bitcode linking time so the appropriate bitcode for the mul isn't linked. Is there a pass I can run that will do the

Just tried the first AJAX example in the rails book (p.391-392, the ''word guessing'' thing), and the AJAX partial used seems to render as a full page. I''m not sure whether it''s a) a partial bug b) some interaction between ajax and partials c) a change since the book came out or d) pilot error I''ve checked the errata pages and it''s flagged up

Hi all, I''ve been offered a short-term contract here in the North of England - around 3 months work, but with RoR I think it will take considerably less time - and am just curious what market rates were right now. I''ve been offered a little under ?1k/week which seems ''right'' for a PHP coder doing this kind of work, but should I be hitting for more, or is

I have just taken on a new site and they were running ruby on rails for their store. I have finally found the database but I cannot get the store to work. I can''t even get it to show up. I have never used this software before and have no idea where to start. All I know is the client was upset when I told them we wou;ld have to start a new store. They apparently have a few hundred of

Greetings, I''m fairly noob with rails and making my first DB driven site with it. I''m using the scaffold generator to develop the admin side of my site (admin_controller) I have three sections that I want to have the administrator edit, and I want to call these from the admin controller that has a layout with navigation to these three sections. When using the scaffold

Hello, I have table called ''listings.'' There are a certain combination of properties which make a listing viewable (e.g., it is confirmed, has been authorized, hasn''t expired, etc.). Each listing has one and only one category. I want to be able to do things like Listing.find_viewable(...) and Category.find(...).viewable_listings, but I see no way to do this

This is way offtopic, but I''ve seen this several times recently and it''s annoying me. If you put "HOWTO" in your subject that means that you''re posting a guide on a particular topic. It doesn''t mean that you''re asking a question about "how to" do something. It''s not like it''s a crisis, but it screws up searches

To make file_column work I have to copy my local variable back to an instance variables like this: <% for product in @products @product = product %> <div class="catalogentry"> <%= image_tag url_for_file_column(''product'', ''image_url'') %></p> This is needed because file_column specifically looks for the instance
