('L' plates still firmly attached)

This is probably dead easy, but I'm utterly stuck - pointers much
appreciated.

I have an overly simple address model:

class Client
  include DataMapper::Resource

  property :id, Serial

  property :name, String
  property :addr1, String
  property :posttown, String
  property :postcode, String
  property :phone, String

  has n, :tickets
end

All I want to do is put the address as a line on the final form before
the table showing a list of client's tickets.  I can display the
individual elements of course but surely I should be able to
concatenate everything along the lines of:
FullAddress:=C.name+", "+C.addr1+", "+C.posttown+", "+postcode+",
"+phone

and then in the view have:
  =C.FullAddress
in order to display the full address

And of course the next step would be to miss out the ", " if an
element was NULL.

Thanks in advance.
