Completely untested legacy bitfield-based role system fixer.

gistfile1.rb

alias_attribute :administrator :IsAdministrator
alias_attribute :consumer :IsConsumer
# etc...

# now you can do checks like:

if @user.administrator?

# and if you need .role:

def role
  case self
  when administrator?
    "administrator"
  when consumer?
    "consumer"
  # etc...
  end
end
