Return ID after create (rails 2.1)

Rails
1

I’m using a Flex app to post to a controller called segments using the
url http://localhost:3000/segments and am able to successfully create
the record in AR. However the block of code that should return the ID
of the new record being created in XML which is this

respond_to do |format|
  if @segment.save
    format.xml  { render :xml => @segment, :status => :created,

:location => @segment }
else
format.xml { render :xml => @segment.errors, :status =>
:unprocessable_entity }
end
end
end

Seems to be returning the following instead

Not Found

`/segments/' not found.
