将基于函数的旧通用CRUD视图转换为基于类的新通用CRUD视图

在我的项目中,我一直在使用Django的通用CRUD视图。我现在想开始在DJango 1.3中迁移到基于类的基于类的通用CRUD视图。我没有发现文档非常有帮助,可以使用一些帮助来转换我的一些基于函数的视图。以下是我的观点片段:

def create_domains(request, *args, **kwargs):
    return create_object(request=request, form_class=DomainForm,
        template_name='customer/create_domains.html',
        post_save_redirect=reverse('manage_domains')
    )

def delete_domains(request, object_id, *args, **kwargs):
    return delete_object(request=request,
        object_id=object_id, model=Domain,
        template_name='customer/delete_domains.html',
        post_delete_redirect=reverse('manage_domains')
    )

我想我会为第一个使用CreateView,为下一个使用DeleteView。这是我到目前为止所提出的:

class DomainCreateView(CreateView):
    form_class = DomainForm
    template_name = 'create_domains.html'
    success_url = 'manage_domains'

class DomainDeleteeView(CreateView):
    model = Domain
    template_name = 'delete_domains.html'
    success_url = 'manage_domains'
    pk_url_kwarg = object_id

你们当中有人能告诉我重写同一个基于类的视图吗?一个小小的启动将是一个很大的帮助,我相信我可以从那里开始。

感谢。

在深入了解Django源代码后,我发现了如何做到这一点。

class DomainCreateView(CreateView):
    """
    Creates a Domain
    """
    form_class = DomainForm
    template_name = 'customer/create_domains.html'
    success_url = reverse_lazy('manage_domains')

    @method_decorator(login_required)
    @method_decorator(only_managers_allowed)
    def dispatch(self, *args, **kwargs):
        """
        The Dispatcher
        """
        return super(DomainCreateView, self).dispatch(*args, **kwargs)

    def form_valid(self, form):
        """
        Validate and save the form
        """
        company = self.request.user.get_profile().company
        self.object = form.save(company)
        return super(ModelFormMixin, self).form_valid(form)


class DomainDeleteView(DeleteView):
    """
    Deletes a Domain
    """
    model = Domain
    template_name = 'customer/delete_domains.html'
    success_url = reverse_lazy('manage_domains')

    @method_decorator(login_required)
    @method_decorator(only_managers_allowed)
    def dispatch(self, *args, **kwargs):
        """
        The Dispatcher
        """
        return super(DomainDeleteView, self).dispatch(*args, **kwargs)
