I am trying to determine the duration of elapsed time minus any interruptions. The method below seems inefficient and silly is there a better method? The user specifies an end_time and a start_time are and records any interruptions as an integer representing minutes. def duration ((end_time - start_time).seconds - interrupt.minutes) ...
I can typically test a regular Test::Unit method using the following commandline syntax for a method "delete_user_test": ruby functional/user_controller_test.rb -n delete_user_test Now when I'm using the shoulda plugin with Test::Unit I try to use the same technique as follows: ... context "Deleting a User" do should "remove user ...
Let's say I have a form where users can search for people whose name starts with a particular name string, for example, "Mi" would find "Mike" and "Miguel". I would probably create a find statement like so: find(:all, :conditions => ['name LIKE ?', "#{name}%"]) Let's say the form also has two optional fields, hair_color and eye_color ...

Hi, we are using Perforce for source configuration management and I have just started to hack some small stuff in Ruby on Rails. As Perforce follows the "check-out before modify" paradigm, and RoR expects to have all files writable for the various script/ stuff, do you know/use any helpers to make RoR work together with Perforce? I know ...
How might you call a Lisp program from a Rails application?... For example, allow the end user to enter a block of text in the Rails web app, have the text processed by the Lisp program and return results to the Rails app? ...
I was doing this kind of thing in my migrations: add_column :statuses, :hold_reason, :string rescue puts "column already added" but it turns out that, while this works for SQLite, it does not work for PostgreSQL. It seems like if the add_column blows up, even if the Exception is caught, the transaction is dead and so the Migration can...
I tried to define a default_scope in the following way: default_scope :joins => :product, :select => "catalog_products.*, products.*" What I'm getting from Rails though is this: SELECT catalog_products.* FROM `catalog_products` INNER JOIN `products` ON `products`.id = `catalog_products`.product_id When I define it as a named_scope...
I'm working on a Rails application which I've set up locally on my OSX Machine. However, the app, which typically runs on a Linux box, connects to a proprietary database via unixODBC. The database manufacturer only provides drivers for Linux and Windows. I did some searching around but couldn't figure out what the state of unixODBC is...

I'm in the processing of developing a GIS component for our product and I have the need to convert NAD83 to WGS84. Does anyone know of any Ruby libraries that are available that do this? Or experience with anything that might do this? I had previously done this using a library in .Net/C#, but so far I haven't had much luck tracking ...
I have a couple users that are getting this CookieStore::CookieOverflow error. I'm suspicious of nginx/passenger because I just switched to that last week (from nginx/thin) and now these are happening. It's always a particular action, but it doesn't happen for all users. I checked to see what I'm storing in the session and I'm not sav...

Hello, I'm pretty new to rails and it's the first time I'm actually using authlogic + acl9. I followed the default installation steps for both plugins. So far everything works great, but I have trouble to find an elegant solution for this problem: Let's say I have a model class called Products. When creating a new Product object I ass...
