Is it true that Rails needs a single column to uniquely identify a row in table? If yes, doesn''t this limit the database design and disables the use of Rails for legacy databases? /Fredrik -- Posted via http://www.ruby-forum.com/.

Our group has several web apps developed in ColdFusion, PHP, and Rails. The ColdFusion and PHP apps are on an older server, and the Rails apps on a new server. Ideally, we''d like them all to share the same server. Our current setup for the Rails server is Apache2.2 with mod_proxy_balancer and mongrel_cluster. We''d like to have specific directories be processed and served by

Hi, I am still new to RoR, so please bear with this newbie question. I would like to have the application in view to press result back to the controller when the periodically_call_remote is called. Right now, this is the code in the view: <div id="get_result"></div> <%= periodically_call_remote(:update => ''get_result'',

Hi, I''m new to Ruby on Rails (and Ruby itself). So far, I''ve been able to find answers to most of my questions in the docs or mailing lists. One thing I haven''t been able to find the answer to is how to stop a periodically_call_remote call. My first Rails app is going to be a front-end for our Ant-based build system at work. While the build is running,

Hi, I''m using Rails 1.1 and the periodically_call_remote() helper to query the server for the progress of a long running action. I''m using the excellent new RJS partials to send a page.replace_html() to update the status information on the page--which works very well. When the action completes I''m also trying to send a redirect_to() by the same approach--which

When I do periodically_call_remote with e.g. :frequency => 30 after initial page load I have to wait 30 seconds until this partial renders first time. Does anybody know how to make ROR to render partial on web page load, and then start periodic calls every 30 seconds? I tried to put <div id=''mydiv''><%= render(:partial, :action=>''myaction'')

I posted this ealier on the web forums but noticed a similar question about this function and one user responded to try this list instead. If anyone can help I would greatly appreciate your suggestions. Q: Is there a way to use periodically_call_remote to run just one time instead of every '':frequency'' seconds? I tried putting the call inside the div container thinking it

I need make progress bar with following function: # Ruby on Rails code <%= periodically_call_remote(:update => ''progress-bar'', :url => { :action => :progress }, :frequency => 0.1 , :complete => "check(request)") %> How I can stop it? If I have this: /* JavaScript code */ function check(request, object) { if (request.responseText ==

I need to know what controller and action the user is currently in to do various things in my layouts/application.rhtml file. Isn''t there is a better way than: <% if params[:controller] == "whatever" && params[:action] == "whatever" %>some html<% end %> I know in the controllers you can just use controller_name, but that is not provided

If there is an exception raised in my worker I rescue it and throw it into the log. This is decent, but it would really help to find out more information. Like the line number, the stack trace, etc. Is this possible? Thanks for your help.

Since MiddleMan is an uninitialized constant in a worker how do you create new workers inside a worker?

I am pretty confident that mailers do not work in backgroundrb. Can anyone confirm this? Because when I try to do Notifier.deliver_some_method I get an error saying it cant find the templates for my email. The funny thing is that when I run script/ runner Notifier.deliver_some_method it works just fine. Any ideas? Thank You, Ben Johnson E: bjohnson at contuitive.com O: 800-341-6826 M:

I have workers that need to be created when I run rake backgroundrb:start. Where do I put this code? Thanks for your help.

I made a worker that run an infinite loop and does the following: while true @logger << "logging #{Time.now}" sleep 2 end In my secong console I did: tail log/backgroundrb.log -f This is so I could see the line getting added to the log every 2 seconds. Then in my other console I started script/console and created a new worker. Then killed it with

Is there a way to determine if attributes were changed? Let''s say in the before_save or after_save method? Thanks for your help.

I have a simple question, but can''t seem to figure this out. I added an in place editor field and didn''t like how it didn''t use the save method. It uses the update_attribute method which does not run validation, etc. So I just added the method in my controller myself: def set_event_url begin @event = Event.find params[:id] @event.url =

Let''s say I wanted to find 3 products from my database and put them in the layouts/application.rhtml view. Where do I find these 3 products? Do I just do it in application.rhtml? <% for product in Product.find(:all, :limit => 3) %> Because I was under the impression that you really don''t want to do this in your views. You should do this in your controllers and

I''m having an argument with my son :) I have a table with about 1500 objects called entries. I need to do something with about 100 of them (schedule manually) I say I should just mark them with a boolean when I have scheduled them. (manual == true) My son says I should pull them out of the entries table and copy them to new objects (lets call them "manual" objects, and store

I''m not sure how to ask this succinctly, so bear with me. I''m trying to learn how to use periodically_call_remote to update a div. I have a table whose rows have the data I want to display in the div, one at a time, every 10 seconds (let''s say). For simplicity let''s pretend each row just has one column, "description," which is just a text
