I've used wsdl2ruby to generate a client for a web service. When a service method raises one of the exceptions defined in the WSDL I'd like to access the exception object's attributes. From what I can tell the exception object has been marshalled into a SOAP::Mapping::Object that's referenced by the detail attribute of the SOAP::FaultErr...
If I try to autocomplete smth in a Ruby file, that has require 'xxx' statement, it starts to scan all files required (and files required by required files as well). and it does that every freakin time! Is it possible to make vim autocomplete to NOT scan required files or just files in particular path (e.g. app/ only)? ...

I'm trying to create a system where I can convert RegEx values to integers and vice versa. where zero would be the most basic regex ( probably "/./" ), and any subsequent numbers would be more complex regex's My best approach so far was to stick all the possible values that could be contained within a regex into an array: values = [ "...
I have a some code that embeds a return_to URL into a redirect (like OpenID) that I want to test: def test_uses_referrer_for_return_to expected_return_to = 'http://test.com/foo' @request.env['HTTP_REFERER'] = expected_return_to get :fazbot # @response.redirected_to looks like http://service.com?...&return_to=[URI-encoded ver...
I'm using rspec-rails, version 1.2.6. In a controller test describe WebsController do ... I don't seem to have access to the controller object in order to stub methods. For example, the following won't work: before :all do @feed = mock_model(Feed) controller.should_receive(:feed_from_params).and_return @feed end I g...
I'm reading a document that talks about a method having a receiver. What's a receiver? ...
In the example below, why do we say "k.send :hello" instead of "k.receive :hello" if, as stated elsewhere, k is actually the receiver? It sounds like k is the sender rather than the receiver. When we say "k.send :hello" who is sending, if not k? (Are you as confused as I am?) class Klass def hello "Hello!" end end k = Klass....
I wanted to make something that looks like this: def make_wrapped_block(&block) puts "take_block:before" func = lambda do puts "Before calling make_wrapped_block's passed block" block.call puts "After calling make_wrapped_block's passed block" end puts "take block:after" func end def make_block make_wrapped_bloc...
If I say x.hello() In Java, object x is "calling" the method it contains. In Ruby, object x is "receiving" the method it contains. Is this just different terminology for expressing the same idea or is there a fundamental difference in ideology here? Coming from Java I find Ruby's "receiver" idea quite baffling. Perhaps someone coul...
From my understanding, Python's twisted framework provides a higher-level abstraction for networking communications (?). I am looking for a Ruby equivalent of twisted to use in a Rails application. ...
Working on a little Ruby script that goes out to the web and crawls various services. I've got a module with several classes inside: module Crawler class Runner class Options class Engine end I want to share one logger among all those of those classes. Normally I'd just put this in a constant in the module and reference it like ...
instead of using exec in our script to do an nslookup, is there an easy way to write it programmatically in PHP, Python, or Ruby? ...
I have a Ruby on Rails application and I need to duplicate some computations in both Ruby and JavaScript. Ruby is used in the server side but I also need to compute a students grade on the browser using JavaScript. My first thought is to build up a JavaScript function using strings, convert it to JSON, ship it to the browser where it i...
If I run this file as "ruby x.rb": class X end x = X.new What is the thing that is calling "X.new"? Is it an object/process/etc? ...
I am wondering how I can target a specific commit SHA in Git for deployment, using Capistrano? It should be something like cap deploy --version=<sha targeted> Can't seem to find the answer to this after a lot of searching. ...
I want to reuse some cucumber steps but can't seem to find the right way. I want to write a step like: Given /^I login with (.*) credentials$/ |type| # do stuff with type being one of "invalid" or "valid" end But then have another step like: Given /^I login successfully$ # call "Given I login with valid credentials" end So in ...
Given the Ruby code line = "first_name=mickey;last_name=mouse;country=usa" record = Hash[*line.split(/=|;/)] I understand everything in the second line apart from the * operator - what is it doing and where is the documentation for this? (as you might guess, searching for this case is proving hard...) ...
I'm planning on teaching a programming elective next year at my high-school. The students would be from 9th to 12th grade with minimal programming experience in ti-basic at best. I've yet to decide on what language to use in it. I fear that if I use something ultra-interpretive and abstract like Ruby or Python I'll be doing them a disser...
