Yes, ActiveRecord has a bunch of callbacks that you can tap into such as before_save, before_validation, etc. You can do something like this:

class Person < ActiveRecord::Base
  before_save :strip_tags

  private

  def strip_tags
    self.name = name.gsub(TAGS, '')
  end
end

How you actually filter the name is up to you. If you have specific questions about filtering content, I would open a different question since you'll get better answers that way. – Peter Brown Aug 19 '12 at 17:14
(dry code problem)How can strip_tags be defined in one place for all models? – Ben Aug 19 '12 at 17:45
Put it in a module and include it in the models you want it in. – Peter Brown Aug 19 '12 at 19:27
