# My pretty prompt:
#  - Truncates the first few dirs in long paths
#  - red/green prompt based on return value of previous command
#  - inserts git branch name if in a repo
# Developed primarily for debian/ubunu systems

# First, some stuff from the Ubunutu .bashrc

  # set variable identifying the chroot you work in (used in the prompt below)
  if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then

This is a new version file /usr/bin/rails generated on my system by installing the Rails 3 Gem. The problem with this executable is that the ‘rails’ command no longer provided a way to execute the executables from Rails 2, because the bin had moved from Rails to Railties. A few more details in the related blog post.

Call a version of Rails 2 like so (after putting the following code in /usr/bin/rails):

rails _2.3.5_ myapp

The second file can be put in /usr/bin/rails2 as a convenience path to run the latest available Rails 2 version easily.

I’m working on both learning authlogic and Rails 3. The process here works (given the Rails 3.0.0.beta1 gem) for me. There is a list of the many resources I complied this from at the bottom of the document.

Travelers beware: this is incomplete, and possibly even wrong. But between the stuff about scaffolding and binary logic’s example app you should be able to get off your feet.

Basic Application¶ ↑

We assume Rails 3 is installed. We will create a rails app as usual.

rails authtest
cd authest
rails g scaffold post title:string body:text
rails g scaffold user username:string fullname:string is_admin:boolean
