Generate an absolute URL in padrino

Sometimes, you just need that absolute URL. Padrino gives you a great little helper to create your urls in th form of url_for. Unfortunately, Padrino's documentation seems to be written from the point of view of someone who is intimately familiar with Rails, which means the total noob trying to get into Padrino without any Rails experience can be left a little flummoxed. Anyway, it is important to realise that Padrino has Sinatra as its base and you can tap into all that goodness that Sinatra offers. Absolute urls are as simple as:

<%= uri url(:controller, :action, :param=>value) %>

Lovely.

Getting started with Ruby on Rails 3.2 and MiniTest - a Tutorial

For fun, I thought I would start a new Ruby on Rails project and use MiniTest instead of Test::Unit. Why? Well MiniTest is Ruby 1.9s testing framework dejour, and I suspect we will see more and more new projects adopt it. It has a built in mocking framework and RSpec like contextual syntax. You can probably get away with fewer gems in your Gemfile because of that. Getting started is always the hardest part - let's jump in with a new rails project rails new tddforme --skip-test-unit Standard stuff. MiniTest sits nicely next to Test::Unit, so you can leave it in if you prefer. I've left it out just to keep things neat and tidy for now. Now we update the old Gemfile: group :development, :test do gem "minitest" end and of course, bundle it all up.....from the command line: $ bundle Note that if you start experiencing strange errors when we get in to the generators later on, make sure you read about rails not finding a JavaScript runtime . Fire up...

Rails 3.2, MiniTest Spec and Capybara

What do you do when you love your spec testing with Capybara but you want to veer off the beaten path of Rspec and forge ahead into MiniTest waters? Follow along, and you'll have not one, but two working solutions. The setup Quickly now, let's throw together an app to test this out. I'm on rails 3.2.9. $ rails new minicap Edit the Gemfile to include a test and development block group :development, :test do gem 'capybara' gem 'database_cleaner' end Note the inclusion of database_cleaner as per the capybara documentation And bundle: $ bundle We will, of course, need something to test against, so for the sake of it, lets throw together a scaffold, migrate our database and prepare our test database all in one big lump. If you are unclear on any of this, go read the guides . $ rails g scaffold Book name:string author:string $ rake db:migrate $ rake db:test:prepare Make it minitest To make rails use minitest , we simply add a require ...

Poor person's guide to managing Ruby versions

Understanding the guts of Ruby Version Management by rolling your own I've been tinkering with a fresh install of Ubuntu 12.10, setting up a nice clean development environment. One of the first things to do, of course, is implement some sort of Ruby version management. RVM and rbenv seem to be the clear winners in this arena, though there are a lot of tools out there that do a similar job . Writing your own version management for your Rubies isn't actually all that difficult. At it's core, we need need two things: A way to segregate the executables of the various versions A way to call the versions at will Segregating versions is trivial - working with files and folders, we can put the various versions into named directories. Actually executing our different versions is not all that difficult either. One way would be to create aliases with version numbers and explicitly call those when we want to use them. The more popular way, however, is to manipulate our PATH ...
