So, we all strive to reduce duplication (DRY) and other smells, and keep our code as nice and clean as possible. For Ruby code, there are a lot of instruments to detect smells, for example the quite nice Caliber service. However, it seems that I have a different definition of code duplication than the tools. I think this might be connec...

Is there something similar to Ruby Benchmark within Rails? I have used Ruby benchmark in the past to compare different bits of code, but none of it was Rails related. I would like to use my application models in some benchmarking to do something along the lines of... #!/usr/bin/ruby require 'benchmark' Benchmark.bmbm do |x| x.report(...
Hi! I'm writing a simple application with Sinatra and Datamapper in Ruby and I have a trouble — when I try to save data into my SQLite database nothing is changing. But when I try to install database or change data from irb it works perfectly. Here is my Datamapper's setup, model and database installing method (this works fine): DataM...
Hello, I'm working on a Ruby on Rails app which has a REST API. I manage two formats JSON and XML. Very often to simplify the use if the API, I'm making includes. But when you add params to to_json and to_xml like :only, :except, it's not only applied on the root object but on all the objects included. Do you know libs or methods to an...
Hi I want to make my rails controller more flexible and try to create some Meta foo for it. I have a problem with the redirect_to method. Can I convert the "edit_admin_post_path()" method from a string or better read out the controller name and pass it dynamicly? this is my code for "post" in my Admin::Posts controller. respond_to do...

I appreciate makefiles and make in all their glory, but I wonder if there isn't a more intuitive way to maintain my c/c++ builds. Has anyone tried replacing their makefiles with ruby scripts to allow for complex and adaptive builds without sacrificing readability? Are there gems that make this easier? ...
For kicks, I'm setting up the build process of my C++ program using rake. I'd rather not reinvent the wheel, however. Are there any ruby gems that have build features similar to the cool ones in SCons (e.g., C++ dependency detection, md5 difference detection, cross-platform pathing, multi-threading, etc.)? ...
What I want is a way of not having to 'require' the class under test in each spec file. So hoping there is a means of setting the root of the source code under test and rspec automatically mapping my tests, or any other means of automatically mapping specs to ruby files. In Rspec for rails this happens magically, but this is not a ra...

I've created an RSA private key in ruby with: require 'openssl' key = OpenSSL::PKey::RSA.generate(1024) I can get the key in PEM or DER formats: key.to_pem key.to_der But there doesn't seem to be a way to get it into PKCS#8 format. The best I've come up with is to call out to openssl in another process: require 'open3' Open3.pope...
I'm trying to read files and create a hashmap of the contents, but I'm having trouble at the parsing step. An example of the text file is put 3 returns 3 between 3 pargraphs 1 4 3 #foo 18 ****** 2 The word becomes the key and the number is the value. Notice that the spacing is fairly erratic. The word isn't always a word (which does...
During RubyAMF and AS3 interaction, I keep getting the error "Client.Data.UnderFlow" in a NetStatusEvent.NET_STATUS on the AS3 side. On the Ruby side I get "ActiveRecord::RecordNotFound (Couldn't find {type} without an ID)", where {type} is the defined type that I'm looking up. A google search suggests that this issue seems to have com...

Basic method DataMapper::Resource.attributes returns a collection of properties, but it does not say anything about types.

I am having trouble figuring out the elegant way to add an array of hashes [{:a=>1,:b=>2,:c=>3},{:a=>1,:b=>2,:c=>3},{:a=>1,:b=>2,:c=>3}] should return [{:a=>3,:b=>6,:c=>9}] I know it would probably involve mapping/reducing, but I can't figure out the right syntax, doesn't help that ruby-doc dot org doesn't match my version I am us...
