python - 将旧的基于函数的通用 CRUD View 转换为新样式的基于类的通用 CRUD View

Question

我在项目中的很多事情上都使用了 Django 的通用 CRUD View 。我现在想开始迁移到 DJango 1.3 中新型基于类的通用 CRUD View 。我没有发现这些文档有很大帮助，并且可以在转换我的一些基于函数的 View 时使用一些帮助。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')
    )

我想我将在第一个 View 中使用 CreateView ，在下一个 View 中使用 DeleteView 。这是我到目前为止所想到的:

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

你们中的一个人可以告诉我重写相同的基于类的 View 吗？一点点的起步将是一个很大的帮助，我相信我可以从那里开始。

谢谢。

在深入研究 Django 源代码后，我找到了如何做到这一点。

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)
