This gist contains a script that will check for collisions between the database table names and column names associated with ActiveRecord models. This type of collision was just revealed to be a security risk in this advisory: https://groups.google.com/forum/#!topic/rubyonrails-security/8CVoclw-Xkk

check_table_column_collisions.rb

def check
  ActiveRecord::Base.send(:subclasses).each do |klass|
    if klass.column_names.include?(klass.table_name)
      raise "#{klass.to_s}'s table name collides with column #{klass.table_name}"
    end
  end
  puts "All Clear."
end
