How to get the value of the bud in the violin. Django

[shizuka]

I need to get it. key database Users And this variable is working. I tried this code:

@login_required()
def index(request):
    key_user = Users.objects.filter(name=request.user)
    for key_user in key_user:
        key = key_user['key']
# worlds = World.objects.get(key_user=key)
return render(request, 'app/index.html')

But he didn't work with a mistake.

TypeError at /app/

'Users' object is not subscriptable
