The problem: I have a collection of people, I want to have a revise.html page that allows me to increment a integer on all the people. if I make a new method in the people_controller it auto sends me to people/revise.. which gets interpreted as show/revise... which is not an id. I understand this happens because of REST constrictions....
I'm trying to parse out some log files with ruby. I have plenty of experience with regexes but the other day I was using rails routes and thought that might be a really neat way to parse out these log files because it would be incredibly easy to understand the parser. Regex, on the other hand, takes several minutes for most people to d...
I was wondering: In python, canon says to use buildout or virtualenv, to avoid installing into the system packages. It's second nature now, I no longer see anything ludicrously bizarre to the practice. It makes a kind of sense. In Ruby, is there something similar? How does ruby deal with this problem? Does ruby have this problem? ...

For example, I had a plan to use mongodb for our system, but now I'm not sure because of luck of transactions and ACID in mongodb. Wh...

I can't find any useful resources online that breaks down Ruby's different flow-control options. Let's assume that I'm iterating over an array within in a method: def a_method things.each do |t| # control options? end end What are my different flow-control options here? How do they differ? retry return break next redo ...
I have a Mix-in that reflects on the receiver class to generate some code. This means that I need to execute the class method at the end of the class definition, like in this trivially dumbed down example: module PrintMethods module ClassMethods def print_methods puts instance_methods end end def self.included(rece...
I primarily work in PHP and prefer to do so since there seem to be more jobs in this language, at least in my area (and I'm still fairly new to it so I want to continue to learn the language better).. but for some things I want to do I need to use the WWW Mechanize library that doesn't work with PHP but does with Ruby (yes I know PHP has...

I already have a windows WAMP server up and running and am using it for my PHP apps, I want to be able to run some small ruby scripts (to interact with a library that is not available in PHP), I don't even need Rails at this point, I just want to run ruby scripts an...
Hi, I'm having some troubles with my Rails app after installing (and removing) Compass. bundle install gives me the following: /Users/[..]/.rvm/gems/ruby-1.9.2-head@rails3beta/gems/bundler 1.0.0.beta.2/lib/bundler/settings.rb:10:in `[]': undefined method `[]' for false:FalseClass (NoMethodError) from /Users/[..]/.rvm/gems/ruby-1.9.2-he...
Sorry to ask such a general question as I'm sure a lot of questions have been asked before about IDE's... but I specifically have major problems running IDE's that are written in non-native languages for Windows (like Java), NetBeans gave me horrible performance and I just tried Aptana and got a similar issue... I have a fast computer (...
