I am trying to find a clean way of referencing an array's index using octal numbering. If I am looking for the array index that is octal 13 it should return the value for a[11]. This is what I have come up with to accomplish it, but it doesn't seem very elegant or efficient: a = [ 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62 ] ...
I'm working on an API integration project in Ruby and I was about to create a class method to somewhat follow what Rails does with the finder methods but I stopped short of doing so because I'm concerned I might introduce a race condition. I wouldn't be storing anything within the member variables, just instantiating objects with the th...

Hey, Will Rails 3 be a modular framework like Merb or Ramaze? By this I mean, can we use any persistence framework (DataMapper or Sequel) and jQuery in Rails 3 application (via the command line for example)? Or the default stack (ActiveRecord, Prototype) is still enforced? (Sorry, I'm pretty new to Ruby/Rails community). Thanks. ...
I'm trying to output RTF (Rich Text Format) from a Ruby program - and I'd prefer to just emit RTF directly without using the RTF gem as I'm doing pretty simple stuff. I would like to highlight specific characters in a DNA sequence alignment and from the docs it seems that I can either use \highlightN ... \highlight0 or \cbN ... \cb1 Th...
I have a simple call JSON.parse(Panda.get("/videos/#{self.panda_video_id}/encodings.json")) Which returns : can't convert Array into String This is because the Panda.get("/videos/#(self.panda_video_id}/encodings.json") call returns an array in the new Panda 1.0.0 gem. I also tried : JSON.parse(Panda.get("/videos/#{self.panda_vi...

Hello, I'm pulling in the RSS feed from Craigslist into a rails app I'm building. When I try and insert content from the posts into my database, there's plenty of bad characters that cause the database to choke. I've tried a few different methods (the Sanitize plugin, hpricot, regexing the input) but nothing seems to work right. I'm ...
It's very simple, I want to handle a normal [show] request with a call to DataMapper like I did in Merb. With ActiveRecord I could have done this: class PostsController def show @post = Post.get(params[:id]) @comments = @post.comments unless @post.nil? end end and it handles the 404 by catching the resource's exceptions. ...
Rails is collection of several gems, all who's source resides in the rails repository, aka active_record has its own gemspec but is at github.com/rails/rails/active_record.
