Chris, great stuff, thanks. Note that \w in a regex *is* a character class, so it does not need to be enclosed in the [ ] brackets if it's by itself. So /@(\w+)/ is all you need. Also, this would need some tweaking to avoid matching the domain name of an email address, for example. (html-pipeline's version does this)

The price is an attribute of the relation between Event and EventType. has_and_belongs_to_many doesn't allow you to add attributes, so you need to create a full model to hold the relation. I don't know what to call it; maybe just EventPrice.

So:

• Event has_many :event_prices
• EventPrice belongs_to :event
• EventType has_many :event_prices
• EventPrice belongs_to :event_type

price is then an attribute of the EventPrice model.

You can use has_many :through to reach through Event to EventTypes (and vice versa) if you need to.
