views.py

def session_auth(fn):
    def inner(request,*args,**kwargs):
        status = request.session.get('session_login')
        if status:
            ret = fn(request)
            return ret
        else:
            return redirect(reverse('login'))
    return inner

@session_auth
def index(request):
    username = request.session['user']
    # print('index')
    return render(request, 'index.html',{'username':username})
