Hi all, I'm running an ubuntu 9.10 server on an amd-64 platform. Everything's pretty much standard, and I've got Sinatra 0.94 running on a ruby 1.8 installation. I want to install passenger in order to easily configure ssl. The problem is, it fails to find the installer. I run sudo gem install passenger or sudo gem install -r ...
Hi all, I was wondering if there was a solution to automatically - from my ruby source code - ask Gem to install various librairies my code my require to work? From what i read on the internet, it seems we are obliged to either use an install script that directly runs "gem install ..." commands or do it manually or some people have pos...
I have a Ruby script that defines a class. I would like the script to execute the statement BoolParser.generate :file_base=>'bool_parser' only when the script is invoked as an executable, not when it is require'd from irb (or passed on the command line via -r). What can I wrap around the statement above to prevent it from executing ...

I have a Rails project and I used Migrations to setup the database schema (I'm using sqlite3). I have a XML file that I want to insert into my database. What's the best way to approach this? I'm thinking there's some Ruby script that I can write once and use to parse the XML file and insert it into my database, but intuitively it feels l...
We have a j2ee/spring/hibernate/tomcat web application already running on production. We are planning to integrate with a 3rd party service(recurly) which provides a ruby client lib. They don't have a java client lib yet. Their service is RESTful and their client is a thin custom wrapper over ActiveResource. I can think of a few ways to ...
As you all know, with Rails it is possible to use Builder::XMLMarkup templates to provide an http reponse in XML format instead of HTML (with the respond_to command). My problem is that I would like to use the Builder::XMLMarkup templating system not with Rails but with Ruby only (i.e. a standalone program that generates/outputs an XML f...

I want to use the current version of bundler (there have been quite some changes from 0.8 to 0.9) to mange the gems of my Rails app. First I created a Gemfile in the root of the app folder and added all the needed gems to it.

Hi, I've made a rails rake task that uploads/crops/re-sizes (with paperclip) silly amounts of images. I wanted to know how to output a message to the terminal when it was running (e.g. chipolata.jpg processed) and at the end, it takes a good few minutes to run and a little feedback would be good. Thanks. ...

I've never done any straight ruby coding - only worked with the Rails framework. I am not sure how to describe the relationships between Classes, other than inheritance relationships. For example, a School object may have many Student objects. I would like to be able to make calls like "myschool.student[2].first_name" and "mystudent.sc...
I'm part of a group that starts a new development project from scratch. Currently it is on hobby-basis but we aim to make it our living in the time frame of 1-2 years. We are senior developers coming from a multitude of languages and techniques with much of the focus on Java for the last few years. Now, we're thinking of choice of tools...
I'm trying to write my 1st Ruby program, but have a big problem. The code has to download 32 mp3 files over http. It actually downloads a few, but then timeouts. I've tried setting a timeout period, but it makes no difference. Run the code under Windows, Cygwin and Mac OS X with the same result. This is the code: require 'rubygems' requ...
I have a custom Rakefile which calls different file tasks. Sometimes a file that is expected doesn't exist, and rake throws a RuntimeError and fails. However, I'd like to do a few things before it fails. So is there any way I could rescue a RuntimeError? Or is there some sort of a magic task which gets called before a complete fail? ...

I've been trying to find a good way of doing this, either on the client side in Javascript or at the last minute within the server. This is a Rails application but it is a pretty generic question.
