I added a middleware django-user-agents
to my application, used for getting user agent information and now my app won't start up. I followed all steps mentioned on their github page: django_user_agents
but cannot get this thing working.
Here's the stacktrace:
Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x000000000520B048>

mw_instance = middleware(handler)
TypeError: object() takes no parameters
Would be really helpful if someone would figure this out.
Feel free to pop a question in case I missed something/something is not clear.
Thanks in anticipation!! :)

The middleware you are trying to use seems not to be compatible with Django version >= 1.10. There is already an open issue on GitHub for your exact problem:
https://github.com/selwin/django-user_agents/issues/13
Their workaround right now is to use the old-style MIDDLEWARE_CLASSES
setting instead of the MIDDLEWARE
setting if possible.
Another option from the associated pull request (https://github.com/selwin/django-user_agents/pull/17) is to create your own middleware extending the other middleware:
from django.utils.deprecation import MiddlewareMixin
from django_user_agents.middleware import UserAgentMiddleware
class CustomUserAgentMiddleware(MiddlewareMixin, UserAgentMiddleware):
pass
And then in your settings.py:
MIDDLEWARE = [
# other middlewares...
'path.to.your.own.file.CustomUserAgentMiddleware',
]
