thanks - I'll have a look at the code - so would it be correct to say then that the Rails framework does effectively cast the params strings to their type prior to any saves to the data? (i.e. its not like it leave this up to the database to do itself is it, i.e. like if there was a date it doesn't just pass the string representation of the data through to the database to store in it's Date field)
