将旧的基于函数的通用CRUD视图转换为新的基于类的通用CRUD视图

Question

我在我的项目中用过Django的通用CRUD视图，已经用了一段时间了。现在我想开始迁移到Django 1.3的新风格基于类的通用CRUD视图。我发现文档不是特别有帮助，所以想请教一下如何把一些基于函数的视图转换过来。以下是我视图的一部分：

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')
    )

我想第一个视图会用到一个叫CreateView的东西，第二个视图会用到DeleteView。这是我目前想到的：

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

有没有人能教我怎么把这个改写成基于类的视图？如果能给我一点启发就太好了，我相信我能在此基础上继续进行。

谢谢！

经过仔细研究Django的源代码，我找到了实现这个功能的方法。

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)
