I want to add one more comment about the benefit from my previous
suggestion.
The worst thing about a dedicated foo.html approach, is that the
controller has to feed (sometimes fake) every variables which are
mentioned explicitly inside the foo.html, even when in error exit,
otherwise you are very likely to get a "global name xxxx is not
defined" error.
With my suggested generic.html which eliminates the need for a
dedicated, decoration foo.html , now I can freely write this kind of
code in my controller, without caring foo.html anymore:
def foo():
# do something
if all_is_ok:
# instead of return dict(msg="ok", partA=dataA, partB=dataB), now
I do:
return dict(DIV(partA,partB))
else:
# instead of return dict(msg="oops", partA=dummyA, partB=dummyB),
now I do:
return dict(whatever="oops")
