MyAPIKeys

[nanchenchen]

$ python manage.py stream MyAPIKeys --poll-interval 30

# The name of the default keys to use for streaming. If not set, we'll just grab one.
    'DEFAULT_KEYS_NAME': None,

I just found the MyAPIKeys AND DEFAULT_KEYS_NAME is so unclear because it is actually username in the ApiKey model.
I expected it to be either app name or username + appname, as what is shown in the Admin panel...:)
