As a long-time Ruby and Rails user, it never struck me until today to really think about the get-and-redirect pattern in Rails. The typical example of this would be calling a create() action, and then redirecting the user to a show() action to display the newly-created item: class JournalEntries def index @entries = JournalEntr...

Let's say I have: object A, B, C each with corresponding models, views, and controllers How would you load them all into one view (site index)? You could use a partial of each model's index, but then methods of that particular controller don't get called so you would have to add that view's methods. Any other suggestions? Thanks! ...

I would like to create a "Hall of Fame" page, where I list the top 10 businesses, by sorting businesses based on average ratings (which would use the Ratings model) and limiting the results to 10. I'm ...
I have a controller within a namespace and would like to cache it's Index. I am successfully caching pages that are not under a namespace, and successfully caching fragments as well. When I visit http//.../house/kitchen it successfully creates /public/house/kitchen.html. However it never finds it, so it is always writing over the cache...

I'm starting to use vlad for new deployments and am wondering what's the best way to set it up so I can use the same tasks for my local development and remote production servers?

Hi All, I'm looking for a mechanism by which to facilitate user preferences. I also want to have a set of "master" prefs that are used if the currently logged in user doesn't have a specific pref set. I see several questions similar to this, but they seem to get into theory instead of simply proposing a quality solution. Basically I'...

It seems that setting multiple instance variables in a controller's action (method) causes problems in the template, only the very first instance variable got passed to the template. Is there any way to pass multiple variables to the template? Thanks! And why, in Ruby's perspective, does the template get access to the instance variables ...
This is a problem I've come across for a couple different projects I'm working on. Since the projects are still under stealth development, and the problem itself is of potentially broader interest and agnostic to them, I'm going to anonymize it - but FWIW, I work primarily with Ruby/Rails and MySQL. Scenario I want to have a system f...

I'm in the middle of trying to upgrade a rails project from rails 2.0.2 to rails 2.3.5 In doing so, I've noticed a change that is driving me nuts. It seems that now by default, any queries that are run by the application get logged to the webrick console (I'm working in Eclipse/Aptana). It used to be that webrick would only show request...
I have three tables: Project, Tasks, and Tags. When migrate the databases in development mode, everything works. But when I run the rake db schema load command for production mode, it isn't migrating the "Tasks" table, hence the app doesn't work. I looked at my production.log file, but there isn't anything there. What am I missing he...
