Title: howto signature the transaction from python?
Post by: alt on December 21, 2015, 09:35:45 am

If I got a transaction like this:

Code: [Select]

{'expiration': '2015-12-21T09:33:30',
 'extensions': [],
 'operations': [[1,
                 {'amount_to_sell': {'amount': 900000000,
                                     'asset_id': '1.3.0'},
                  'expiration': '1969-12-31T23:59:59',
                  'extensions': [],
                  'fee': {'amount': 500000, 'asset_id': '1.3.0'},
                  'fill_or_kill': False,
                  'min_to_receive': {'amount': 1900000,
                                     'asset_id': '1.3.1'},
                  'seller': '1.2.18'}],
                [1,
                 {'amount_to_sell': {'amount': 2000000,
                                     'asset_id': '1.3.1'},
                  'expiration': '1969-12-31T23:59:59',
                  'extensions': [],
                  'fee': {'amount': 500000, 'asset_id': '1.3.0'},
                  'fill_or_kill': False,
                  'min_to_receive': {'amount': 1100000000,
                                     'asset_id': '1.3.0'},
                  'seller': '1.2.18'}]],
 'ref_block_num': 30631,
 'ref_block_prefix': 2405814624,
 'signatures': []}

That script is NOT OPERATIONAL yet ..
Hopefully I can complete it in Q1 2016 .. but at the current stage it does not yet do what it should ..

I would recommend you use the transaction builder of the cli_wallet as described here:
http://docs.bitshares.eu/bitshares/tutorials/construct-transaction.html

Transaction signing is currently only implemented in C++ (cli_wallet) and javascript/coffee script for the Web wallet ..

it's very hard to understand these code, after a hard try,  I have to give up ....
BTW, can you upload python-graphine to the Python Package Index?
then I can add your package as dependency.
https://pypi.python.org/pypi

Just did so .. the package should be called "graphenelib". Please tell me if you find anything not ok. Never used Pypi for distribution ..

Gonna work more on the transaction signing next year
