有没有办法request.session从基于类的视图中获取信息？

例如，我有

from django.views.generic.edit import FormView

class CreateProfileView(FormView):
    def form_valid(self, form):
        # --> would like to save form contents to session here

        return redirect(self.get_success_url())

我唯一能想到的就是as_view添加

def as_view(self, request, *args, **kwargs):
    self.session = request.session
    super(CreateProfileView, self).as_view(request, *args, **kwargs)

上课。但这看起来很丑。还有另一种方法吗？
