Today I was struggling with why the following did not work for me in one of
my tables:
Field('modified_on', 'datetime', default=request.now, update=request.now)
After some fiddling I found that writable=False must be explicitly added for
this to work properly.
--> Field('modified_on', 'datetime', default=request.now, update=request.now,
writable=False)
I understand that it does not make sense to have writable=True when you added
update=... to a field (same counts if you use compute), but I believe it does
make sense to add this in the documentation (in the DAL chapter describing the
Field constructor) - just so other people don't waste time figuring this out.
Best regards,
Tom.
