Question

我正在Django 1.3中实现基于类的视图，我发现自己在这个场景中我的CreateView，UpdateView和DeleteView几乎完全相同。有没有办法用一个视图CreateUpdateView或类似的东西来实现它，或者这是实现CBGV的标准方法？

另外，在ThingyAdd中我没有像ThingyEdit那样指定模型，但它们都运行良好。我假设模型是由form_class，ThingyForm的meta部分中定义的模型暗示/拾取的，它是一个ModelForm。这个假设是否正确？

class ThingyAdd(AuthMixin, CreateView):
    form_class = ThingyForm
    context_object_name='object'
    template_name='change_form.html'
    success_url='/done/'

class ThingyEdit(AuthMixin, UpdateView):
    model = Thingy
    form_class = ThingyForm
    context_object_name='object'
    template_name='change_form.html'
    success_url='/done/'

class ThingyDelete(AuthMixin, DeleteView):
    model = Thingy
    form_class = ThingyForm
    context_object_name='object'
    template_name='delete_confirmation.html'
    success_url='/done/'

你可以创建另一个mixin

class ThingyMixin(object):
  model=Thingy
  form_class=ThingyForm
  template_name='change_form.html'
  context_object_name='object'
  success_url='/done/'

然后在你的观点中：

class ThingyAdd( AuthMixin, ThingyMixin, CreateView ):
  pass

class ThingyEdit( AuthMixin, ThingyMixin, UpdateView ):
  pass

class ThingyDelete( AuthMixin, ThingyMixin, DeleteView ):
  template_name='delete_confirmation.html'

基于类的通用视图和DRY
