I have had some working code (coded in pybitshares) that recently encountered errors. I did not change the code so I was wondering if some pybitshares code changes was the cause of the new errors?

Here is a small snippet of code that illustrates the problem:

from pprint import pprint
from bitshares.account import Account
from bitshares.market import Market

#This code works fine...
marketObj = Market("OPEN.EOS:BTS")
t = marketObj.ticker()
print(t)
#Below generates an error (same code, different market parameter):
marketObj = Market("OPEN.EOSDAC:BTS")
t = marketObj.ticker()
print(t)

when I execute this code the result is:
python3 bug_report.py

{'latest': 79.72939583253 BTS/OPEN.EOS, 'core_exchange_rate': 66.11000000000 BTS/OPEN.EOS, 'quoteVolume': 450.907329 OPEN.EOS, 'lowestAsk': 81.46565644572 BTS/OPEN.EOS, 'highestBid': 79.72939583253 BTS/OPEN.EOS, 'percentChange': 6.97, 'baseVolume': 35,861.43141 BTS}
Traceback (most recent call last):
  File "bug_report.py", line 11, in <module>
    t = marketObj.ticker()
  File "/home/plview/HUG/lib/python3.5/site-packages/bitshares/market.py", line 174, in ticker
    data["percentChange"] = float(ticker["percent_change"])
ValueError: could not convert string to float:


Any ideas on what is causing this? Or how to correct it?

I'm having difficulty obtaining the current supply of a UIA using pybitshares.
When I look at the data in the Asset() call I see the "dynamic_asset_data_id" which is what I believe I need to access to obtain the current_supply for the UIA (I believe this from reading the Graphene doc).

I have the following code that provides me with the asset info:

a = Asset(asset_id)
pprint(a)
for i in a:
    print(i, a)

I obtain the following output when "asset_id" = "1.3.4106":

<Asset 1.3.4106>
symbol RUDEX.EOS
dynamic_asset_data_id 2.3.4106
options {'issuer_permissions': 79, 'extensions': [], 'description': '{"main":"RUDEX.EOS asset is backed 1:1 by the real EOS on EOS blockchain (https://eos.io), and can be deposited and withdrawn using gateway operated by RuDEX (https://rudex.org).","short_name":"EOS","market":""}', 'max_market_fee': 0, 'whitelist_markets': [], 'core_exchange_rate': {'quote': {'amount': 10000, 'asset_id': '1.3.4106'}, 'base': {'amount': 3000000, 'asset_id': '1.3.0'}}, 'whitelist_authorities': [], 'max_supply': '100000000000000', 'blacklist_authorities': [], 'flags': 4, 'market_fee_percent': 0, 'blacklist_markets': []}

The output in orange above is what I believe I need to inspect to obtain the current supply of the UIA.

I have tried to use the AssetId call from the bitsharesbase.objects:

from bitsharesbase.objects import AssetId

o = AssetId('2.3.4901')
pprint(o)

which outputs:
<bitsharesbase.objects.ObjectId object at 0x7fcd39eef400>

I have tried a number of approaches but I keep getting error messages like: argument of type ObjectId is not iterable.

I'm struggling to inspect that object!

Can anyone give me a pybitshares example of how to obtain the current_supply for a UIA?
