Here's a way to make a relation immutable that doesn't break.
# Prevent self.user from being changed
alias_method :old_user_assign, :user=
def user=(new_user)
if self.new_record?
old_user_assign new_user
else
logger.warn "Attempt to modify user of record, id=#{self.id} with user id=#{new_user.id}"
return false
end

A test that fails when this solution, http://stackoverflow.com/a/6456889/270511, is applied.
test "inverse of user.profiles" do
user = create :user
profile = create :profile, user: user
assert_equal profile, user.profiles.first, "profile == user.profiles.first"
end

lsiden / my-rvm-prompt
Created January 8, 2012 06:28
Wrapper for rvm-prompt that searches parent directories for files that tell we're in a Ruby project dir or sub-dir
#!/bin/bash
# Use this script instead of ~/.rvm/bin/rvm-prompt
# and the output of rvm-prompt will show up in your command prompt
# only if you are in a Ruby project directory.
