Thanks for all the help on this issue - I learned a lot more than I
expected from the discussion.
Looks like the save! method would be the way forward.
After all this though, I actually went back and implemented it in a
different way so the url didn't need to be saved in the database after
all and could be reconstructed from the id value. This meant I could
just use a method like Kristian suggested:
def url
"/mysite/#{self.id}"
end
Thanks again for the ideas and advice everyone,
DAZ
