Currently, I am playing around with steem-python.
I wanted to add some missing escrow functions.
And now I hit a wall.
Something is very wrong, I just don't know what.
Here are my thoughts:
You just need to change 2 files:
steem/commit.pysteembase/operations.pyIn steem/commit.py add following function:
def escrow_transfer(self,to,agent,fee_amount,fee_asset,escrow_id=None,sbd_amount=0,steem_amount=0,ratification_deadline=7 * 24 * 60 * 60,escrow_expiration=7 * 24 * 60 * 60,json_meta=None,account=None):
if not account:
account = configStorage.get("default_account")
if not account:
raise ValueError("You need to provide an account")
assert fee_asset in ['STEEM', 'SBD']
op = operations.EscrowTransfer(
**{"from": account,
"to": to,
"agent": agent,
"escrow_id": escrow_id or random.getrandbits(32),
"sbd_amount": '{:.{prec}f} {asset}'.format(
float(sbd_amount),
prec=3,
asset="SBD"
),
"steem_amount": '{:.{prec}f} {asset}'.format(
float(steem_amount),
prec=3,
asset="STEEM"
),
"fee": '{:.{prec}f} {asset}'.format(
float(fee_amount),
prec=3,
asset=fee_asset
),
"ratification_deadline":transactions.fmt_time_from_now(ratification_deadline),
"escrow_expiration":transactions.fmt_time_from_now(escrow_expiration),
"json_meta":json_meta
}
)
return self.finalizeOp(op, account, "active")
Also, you need to add from steembase import transactions because we are using from there fmt_time_from_now.
Next step, change steembase/operations.py:
class EscrowTransfer(GrapheneObject):
def __init__(self, *args, **kwargs):
if isArgsThisClass(self, args):
self.data = args[0].data
else:
if len(args) == 1 and len(kwargs) == 0:
kwargs = args[0]
meta = ""
if "json_meta" in kwargs and kwargs["json_meta"]:
if isinstance(kwargs["json_meta"], dict):
meta = json.dumps(kwargs["json_meta"])
else:
meta = kwargs["json_meta"]
super().__init__(OrderedDict([
('from', String(kwargs["from"])),
('to', String(kwargs["to"])),
('agent', String(kwargs["agent"])),
('escrow_id', Uint32(int(kwargs["escrow_id"]))),
('sbd_amount', Amount(kwargs["sbd_amount"])),
('steem_amount', Amount(kwargs["steem_amount"])),
('fee', Amount(kwargs["fee"])),
('ratification_deadline', PointInTime(kwargs["ratification_deadline"])),
('escrow_expiration', PointInTime(kwargs["escrow_expiration"])),
('json_meta', String(meta)),
]))
now we write a small test script:
from steem import Steem
from steem.commit import Commit
s = Steem()
c = Commit(steemd_instance=s,debug=True)
returncode = c.escrow_transfer(to='nanobot', agent='microbot', sbd_amount=0.01,fee_amount=0.001,fee_asset='SBD',ratification_deadline=100,escrow_expiration=100,account='isnochys')
print(returncode)
We enter our passphrase for the wallet, where all keys are store and get this error:
raise RPCError(error_message)
steembase.exceptions.RPCError: 3010000 tx_missing_active_auth: missing required active authority

Missing Active Authority isnochys ..
Come on, thats me!
I do all the shenanigans with this account!
What step did I miss?
The active key should be the right one..
Oh, let's have a qiock look, how your outpot changes, when we set no_broadcast=True:
$ python test.py
Fri, 26 Jan 2018 10:19:15 +0000
Passphrase:
Not broadcasting anything!

Hmm, the function is working, broadcasting is the issue here:(
