Hi Daniel
Yes, as a database developer for many years I am used to a world
populated by rows and columns. I realise Django does things
differently. Understanding the differences is a bit tricky.
My reference to ifchanged relates to the loop in the template that
will need to display or not certain fields depending on whether their
value changed or did not, in each successive "row".
Thanks for your clear explanation. It helped greatly.
Mike
