# Rails edge includes pluggable sanitizers for mass assignment. Really cool is the
# StrictSanitizer which raises an exception instead of a log message, which makes 
# problems easier to spot in development.
# For the time being, there seems to be no way to achieve this in Rails 3.1 via
# configuration. Monkey patching to the rescue!
# Copy the gist into config/initializers and configure the environments in which the
# exception gets raised.
