django - 使用 Django-subdomains 'WSGIRequest' 对象没有属性 'subdomain'

Question

我正在使用 Django-Subdomain 包，每次'WSGIRequest' object has no attribute 'subdomain'运行此视图时都会收到此错误。

    def post(self, request):
    register_form = StaffRegisterationForm(request.POST)

    if register_form.is_valid():
        staff = register_form.save()
        print(dir(request))
        return redirect('account:dashboard',     subdomain=request.subdomain)
    else:
        print(register_form.errors)
        return HttpResponse('form is invalid')

这是我在设置文件中的中间件：

    MIDDLEWARE = [
