What is the problem with the A() helper? Is it that the URL is a relative
URL rather than an absolute URL? If you need an absolute URL, you can do:
A('myrepresent', _href=URL(..., scheme=True))
If that's the issue, the leaving scheme=True will work in both cases, so
you don't necessarily need to check where the call is coming from, but if
you want, you can do:
def normal_page_function():
table = db(db.atable.id>0).select()
db.atable.oneofmyfields.represent = lambda value, record: A(
'myrepresent',
_href=URL(..., scheme=request.function != 'normal_page_function'))
That simply checks whether request.function is the normal_page_function,
and if not, it sets "scheme" to True.
