Okay, I know this will probably be a very easy question. But I am discovering that RonR makes just about everything easy. The problem is, it takes me a few hours to figure out that I can do it the easy way. I need to know how to move to the next record in a database. I want to format my out put in a table. For example, I want a 3 by 3 table. So record one goes in the first cel...

...'m building a collection of desktop app''s and want to use ruby, and Active Record in particular, as an intermediary layer to my databases. I''m not sure how to connect my development environment, Runtime Revolution, to Ruby and Active Record. One option is to just set up a RonR environment and have my app''s make calls that return regular text results instead of html pages, but I haven''t looked into how to do that yet. There are some downsides to this, including preventing any local ruby code. Another option would be to make socket calls to a local R...

...''Big Picture'' of how Ruby on Rails applications are deployed and operate in distributed environment (one deployment server, many remote servers). I follow AWD by Dave Thomas'' explanation from pages 624-626. From reading these pages I have these questions; 1.

Is Mongrel the actual program running that receives the HTTP request and runs the code against the RonR libraries and the application code? 3. How does Mongrel know where the '...

Hello, I''ll try to keep this short BUT, I''ve got little/no experience with programming. In fact, my only background is using Cold Fusion (since 1996 and VERY little of that for the past 5 years as I''ve been playing as a Manager-type at my jobs so I haven''t had to do any hands-on stuff for a while). My question: Would Ruby on Rails be a good platform to get

...t I have access to this user automatically in every view. What is the generally recommended way of doing this -- should I put a call to this method in the constructor of the controller and assign it to an instance variable there? Or should I put it in a view helper instead? Thanks for any tips...RonR is proving to be pretty awesome (I guess you all know that), so glad to be getting into the swing of it.

Hi, Sometime in the near future I''m going to attempt an installation of Rails on one of our school servers, so that a few of our most talanted students also will have the opportunity to learn RoR. The problem is that I''m not entirely sure on the best way to proceed, and I''m the only teacher on the school with Rails experience, but only for Windows. The server runs

I have been working through the Agile Web Development with Rails book doing the Depot tutorial. I have completed it and it works but I cant say I understand how and why. My question is this "After adding products to the Cart, how do I then give users the option to delete just one item and not empty the whole cart?" I''ve been playing around with all sorts of code, just making

Hey, I need to get the number of years (as a number) between two dates. Here is what I have as a helper. # Returns the number of years between now and the specified date. def years_ago(date) dateDifference = DateTime.now - date results =Date.day_fraction_to_time(dateDifference) return results[0] / 24 / 365; end I''m sure there is a better way to do this.

Hi, A few days ago I submitted the following ticket http://dev.rubyonrails.com/ticket/596 asking that ActiveRecord::Timestamp also apply for the join tables of habtm. The answer was that it was left for milestone 1.x, and since I think that without this functionality rails 1.0 would be incomplete, I''m raising the issue here to discuss it. My use case is very simple, I
