I've narrowed down the problem. I dropped the table then added it again and
started removing fields and doing the create. My problem is a field called
'expiration' that I want to set automatically for the user. My model
includes 3 tables: tiers, groups, and accounts. Each account references the
group it's in (every account is in a group), and each group references a
tier. When an account is created, I want the expiration field of the
account to be:
(time since epoch in seconds)+(the new account's assigned group's tier's
TTL [days] in seconds) which I have tried to achieve like so:
Field('expiration', 'time',
required=True,
notnull=True,
default=time(),
writable=False,
represent=lambda expiration, row:
datetime.datetime.fromtimestamp(int(expiration)),
compute=lambda row: time()+row.batch.tier.ttl*24*60*60)
note that row.batch is the account's reference to a group (but it can't be
called group since that is a reserved word)
This produced problems with compute, so I circumvented by commenting it out
and adding this to the creation/insert controller:
group = __get_group()
db.accounts.batch.default = group.id
db.accounts.expiration.default = time()+(group.tier.ttl*24*60*60)
form = crud.create(db.accounts, message='Account Created', next=URL(
'accounts','review')+'/[id]')
I am missing something... because now i'm getting:
<type 'exceptions.ValueError'> need more than 2 values to unpack
...stumped.
