AttributeError: 'Consumer' object has no attribute 'database'

The Consumer class holds an instance variable db, but at least the query method for type rows requires that it has an instance variable called database. It leads to e.g.,

...
    out = consumer.query('condor_failures', 'rows', start, end)
  File "/usr/lib/python3.6/site-packages/ligo/scald/io/influx.py", line 656, in query
    return self.retrieve_rows_by_tag(s['measurement'], start, end, s['tag_key'], aggregate=s['aggregate'], **kwargs)
  File "/usr/lib/python3.6/site-packages/ligo/scald/io/influx.py", line 704, in retrieve_rows_by_tag
    return _retrieve_rows_by_tag(self.client, self.database, measurement, self.schema[measurement], start, end, tag, aggregate=aggregate, dt=dt, datetime=datetime)
