Python 删除视图扩展

我得到以下错误：

class BaseDeleteViewMixin():
    template_name = 'confirm_delete.html'

    def get_success_url(self):
        return reverse_lazy('index-' + self.model._meta.model_name)

    def post_override(self, view_class, request, *args, **kwargs):
        self.object = self.get_object()
        if "cancel" in request.POST:
            url = self.get_success_url()
            return HttpResponseRedirect(url)
        else:
            return super(view_class, self).post(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        klass = type(self)
        return self.post_override(klass, request, *args, **kwargs)


class PersonDeleteView(BaseDeleteViewMixin, DeleteView):
    model = Person

方法帖子，放置在PersonDeleteView中

Request Method: POST
Request URL:    http://192.168.33.10:8000/contractor/person/111/delete/
Django Version: 1.7.4
Exception Type: RuntimeError
Exception Value: maximum recursion depth exceeded while calling a Python object
Exception Location: /usr/local/lib/python2.7/dist-packages/django/db/models/sql/compiler.py in __call__, line 59

很好。 如何正确覆盖BaseDeleteViewMixin中的post

我的目标是创建任何ModelNameDeleteView，而不覆盖其中的帖子。但是

我选择下一个解决方案：

 class PersonDeleteView(BaseDeleteViewMixin, DeleteView):
    model = Person
    def post(self, request, *args, **kwargs):
        klass = type(self)
        return self.post_override(klass, request, *args, **kwargs)

type（self）

将返回对象的实际类（

PersonDeleteView

），而不是该代码所在的类（

BaseDeleteViewMixin

），因此

super

将在

PersonDeleteView

的上下文中启动。这将导致从

BaseDeleteViewMixin

再次启动post方法，而不是从

DeleteView

启动（正如您所期望的那样）

只需在您的

super

调用中硬编码您的mixin类名。

您的问题是什么？

class BaseDeleteViewMixin():
    # other code
    def post_override(self, request, *args, **kwargs):
        self.object = self.get_object()
        if "cancel" in request.POST:
            url = self.get_success_url()
            return HttpResponseRedirect(url)
        else:
            return super(kwargs["view_class"], self).post(request)


class PersonDeleteView(BaseDeleteViewMixin, DeleteView):
    model = Person
    def post(self, request, *args, **kwargs):
        return self.post_override(request, view_class=PersonDeleteView)
