Thanks for pointing this out Jon, I didn't realise there was a string
property. I've just been looking at the docs, but can't find what the
upper limit for the string type is (or what the difference between a
String and Text actually is).
In this case the :salt property will always be a 2-character string.
It's used to add some randomness to the short-urls I'm building.
I've also got fields of :email and :name that I think should probably
be of type String too.
There's also a 'message' filed, but that could be long so Text is
probably better, yes?
On a related matter, does it help adding a length argument such
as :length => 2 to these properties?
cheers,
DAZ
