AttributeError at / 'NoneType' object has no attribute 'as_meta'
I followed all the instruction given in Github, created virtualenv and added secret keys in the .env file and so on. When I launched server by
python3.6 manage.py runserver
the following screenshot popped up in my local server.

I do not know what this means. Please inform me how to fix this. Thank you!
Hi,
Try to create a superuser, go to the /admin and create an event. Populate it with some dummy data and it should work.
@dingzhen93 missing conference that needs to be created in DjangoAdmin, we need to have a failover for this.
Feel free to make a pull request ! :)
Will it suffice to make a simple check in core/views if there are any conferences?
