Cannot run dazl introductury example

Questions

I’d like to run the following introductory example from the dazl documentation:

import asyncio
import dazl

async def main():
   async with dazl.connect(url='localhost:6865', read_as='Alice') as conn:
      async for event in conn.creates():
         print(event.contract_id, event.payload)

# Python 3.7+ or later
asyncio.run(main())

See dazl.ledger

On ‘localhost:6865’ a sandbox is running.

I get the following error message:

line 6, in main
    async for event in conn.creates():
AttributeError: 'Connection' object has no attribute 'creates'

What am I doing wring?

My apologies: the docs are incorrect.

The correct version is this:

import asyncio
import dazl

async def main():
   async with dazl.connect(url='localhost:6865', read_as='Alice') as conn:
      async with conn.query('*') as stream:
         async for event in stream.creates():
            print(event.contract_id, event.payload)

# Python 3.7+ or later
asyncio.run(main())

We’ll update the docs as well. Thanks for bringing this to our attention!
