There will probably be better solutions as we become more experienced with using Bundler, and more command line tools become Bundler-aware.
b will use bundle exec if there is a Gemfile in the working directory, and run the call without Bundler otherwise.

Bundler requires Rubygems >= 1.3.6. Run gem update --system if you have an older version.
It also is not compatible with older versions of passenger, so bring that up to date as well (2.2.15 works).
If you installed RubyGems through apt (which you should never do!), you may see a message giving you a hint to use apt to update.
Some people advise to install the 'rubygems-update-1.3.7' gem on Ubuntu systems if you used apt to install RubyGems.
I did that - and lost all...
Sometimes files attain executable-flags that they do not need, e.g. when your Windows VM copies them over a Samba share onto your machine.
From inside your Rails project directory call regularly:
geordi remove-executable-flags
Runs chmod -x on Ruby, HTML, CSS, image, Rake and similar files.

Boolean attributes can now be set by appending "which", "that" or "who" at the end:
Given there is a movie which is awesome
And there is a movie with the name "Sunshine" that is not a comedy
And there is a director who is popular
Instead of "and" you can now also use "but" and commas to join sentences:
Given there is a movie which is awesome, popular and successful but not science fiction
And there is a director with the income "500000" but with the account balance "-30000"

popthis is awesome when used with inaction_mailer.
Install the gem:
sudo gem install popthis
Start the server:
popthis tmp/sent_mails/ # e.g. the folder containing the .txt-mails generated by inaction_mailer
Now, configure your mail client as follows:
Server: localhost
Protocol: POP3
Port: 2220
Username: anything
Password: anything
Capybara does not play nice with sites that have some actions protected by SSL, some not. A popular way to implement this in Rails is using the ssl_requirement plugin by DHH, which redirects a requests from HTTP to HTTPS if the requested action requires SSL and vice versa.
Capybara follows the redirect, but seems to forget the changed protocol for the next request. The only hack-free workaround right now is to use URLs in lieu of paths everywhere (links, form actions).

Our awesome collection of rspec helpers (formerly known as "spec_candy.rb") is now available as a gem. It works, it is tested and there will be updates.
Add rspec_candy to your Gemfile.
Add require 'rspec_candy/helpers' to your spec_helper.rb, after the rspec requires.
YARD 0.6 adds the ability to serve documentation for gems as well as the current project with yard server. Just like gem server in RubyGems, you can serve gem docs. The advantage to YARD’s server is that you don’t need to pre-generate the static docs (with a gem install) before running the server. If you installed your gem with --no-rdoc, YARD will just generate it on the fly!
Try our Apify gem which solves many problems you will be having.

Ancestry is a gem/plugin that allows the records of a Ruby on Rails ActiveRecord model to be organised as a tree structure (or hierarchy). It uses a single, intuitively formatted database column, using a variation on the materialised path pattern. It exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants) and all of them can be fetched in a single sql query. Additional features are STI support, named_scopes, depth caching, depth constraints, easy migration from older plugins/gems, integrit...
Until May 2011 our gems have been created with Jeweler, which is a helper library to package code into a gem. You know a gem was cut with Jeweler if you see the word jeweler in a gem project's Rakefile.
This note describes how to update a gem that was cut using Jeweler. Note that this can be traumatic the first time. It would be great to have an easier workflow for this. Jeweler is deprecated these days because you can

We built cucumber_spinner to have a progress bar for Cucumber features, which also outputs failing scenarios as soon as they fail.

If you use CucumberSpinner::CuriousProgressBarFormatter and a feature fails, the according page will show up in your browser.

rspec_spinner is a progress bar for RSpec which outputs failing examples as they happen (instead of all at the end).
gem install rspec_spinner
script/spec -r rspec_spinner -f RspecSpinner::Bar -c
alias ss='script/spec -r rspec_spinner -f RspecSpinner::Bar -c'
There's also an alternate runner RSpecSpinner::Spinner which shows a spinner and the name of the current spec instead of a progress bar.

To parse XML-documents, I recommend the gem nokogiri.
xml = Nokogiri::XML("<list><item>foo</item><item>bar</item></list>") parses an xml string. You can also call Nokogiri::HTML to be more liberal about accepting invalid XML.xml / 'list item' returns all matching nodes; list item is used like a CSS selectorxml / './/list/item' also returns all matching nodes, but .//list/item is now an XPath selector

When you need to patch an existing gem, one way is to "vendor" the gem by copying it into the vendor/gems directory of your Rails project. You can then make any changes you require and Rails will use the vendored version of the gem after a server restart. Unfortunately you need to perform some additional steps to marry Rails and the copied gem. This notes describes what to do.
This is super-painful. If you just copy the gem to vendor/gems, Rails will complain:
Unpacked gem foolib in vendor/gems has no s...
