A VERY partial implementation of .gitignore semantics in Ruby...
#!/usr/bin/env ruby
require 'set'
# This code is meant to demonstrate the difficulty of actually applying .gitignore semantics manually. It supports a key subset of .gitignore
# behaviors, including:
# * Anchored and unanchored patterns/globs.
# * Un-ignoring of patterns/globs, with the same quirky semantics as git.
# * Escaping a leading hash in a pattern.
# * User-wide exclusion list.
# * Top-of-repo .gitignore.

Proposal for Improving Mass Assignment

For a while, I have felt that the following is the correct way to improve the mass assignment problem without increasing the burden on new users. Now that the problem with the Rails default has been brought up again, it's a good time to revisit it.

Sign Allowed Fields

When creating a form with form_for, include a signed token including all of the fields that were created at form creation time. Only these fields are allowed.

To allow new known fields to be added via JS, we could add:
