I am having some trouble installing an app on MediaTemple's Grid Servers... I'm deploying with cap and github... everything seems to go ok with those, but the app won't start up. There seems to be a problem with my database.yml file? I've checked for space errors and those all look good. Here is a copy of the console when I try and st...
I built a basic search form that queries one column in one table of my app. I followed episode 37 Railscast: http://railscasts.com/episodes/37-simple-search-form. Note I just posted another search related question, but it's on a completely different issue. In my app, the search queries the zip code column of my profile table, and retur...
Django as a framework is a neat little package. There are very few files (compared to Rails) and it's got a clean structure. The fact that you can plug and unplug apps between different projects is an extremely nifty feature. At the same time, Ruby's hacking ability is unparalleled. It's complete object-orientedness makes it more express...
I am (quite) an experienced programmer but totally new to Ruby and Ruby on Rails. RoR looks great to get working quickly, specially the automatic screen generation for CRUD operations. It really it gets you productive quickly. The questions is with the last 20% of the work, when I must finish my application. Won't RoR conventions stan...
If there's an exception in a Rails application, one gets an error page with the call stack, request parameters and a code excerpt. Is it possible to create a different output if the request is an XHR request? Is it possible to re-define the exception output in general? (I assume that would automatically answer the first question) ...
Does ruby or rails provide a method to order strings in a specified order? Say that I have the following priorities "Severe, High, Medium, Low". These priorities are not going to change frequently (if at all). I have a Task model with a priority column: tasks - id (integer) - name (string) - priority (string) I'd like to get ...
Hi! I've got a problem when I used a new templates functionality in Rails 2.3 (updated InstantRails on Windows Vista). I created a template and called it test.rb. test.rb run "gem sources -a http://gems.github.com" I tried to execute rails tt -m test.rb and got: create log/development.log create log/test.log applying template:...
I have a problem with GeoRuby conflicting with Authlogic. I set up a very simple application that only lets me register and log in and out useing Authlogic. This works fine. Then I added GeoRuby to the application and I get the error: wrong number of arguments (1 for 2) when the current_user is called in the view. I'm quite new to...

Hello, this is my first post on this website, but I'm all the time getting answers for my questions here, through other users, so thank you very much. Well, actually I'm creating a web application, specifically on rails. All the models structure were built and now I was pretending to start to build the controllers and routing. So, I hav...
What is the best way to architect a Rails app to handle two distinct classes of users? For a marketplace there'll be Buyers and Sellers. There will be overlapping functionality in editing the profiles and such, but most the funcitonality will be distinct. Is the approach in the following post a good way to do it? I'm hoping to use RE...
Often I find myself inserting logging statements like this into my code: logger.info("orphaned_annotations: ".upcase + orphaned_annotations.to_s) logger.info("orphaned_anchors: ".upcase + orphaned_anchors.to_s) It seems like this would be a pretty common use-case -- is there an easier way to get this kind of functionality? ...

I always hear about UML being used in Java projects but never in Ruby ones. Is this just a cultural difference or is there less of a need for modeling in Ruby development because it's part of a more 'agile' culture? ...
Hi, Stackoverflow folks. I want to teach myself RoR. I am a newbie to Web development. I hate reading manuals and learn best by doing, rather than reading. I understand the basics of RoR conventions and the idea behind it. But for me the best way to learn how to use stuff is to have a step-by-step guide walk me through stuff like setup, ...
Given two model classes, Foo and Bar, I want Foo to have 3 references to separate instances of Bar using 3 different property names, with the foreign key on the Foo table. Bar will be managed separately and can belong to many instances of Foo. This somewhat explains it, obviously has_one is the wrong association to use (I think?): Foo ...
I want to use the before action to optionally interrupt the processing if it fails to comply certain criteria (e.g. the object is not owned by such user etc) I need to use this because I have a more complicated scenario that I need the object to be loaded before the access rights could be determined, so I would have situations where I w...
