基于类的通用视图和DRY [英] Class Based Generic Views and DRY

问题描述

我正在Django 1.3中实现基于类的视图，并且在这种情况下，我的CreateView，UpdateView和DeleteView几乎相同.有没有一种方法可以仅使用单个视图CreateUpdateView或类似的视图来实现，或者这是实现CBGV的标准方法吗?

I'm implementing class based views in Django 1.3 and I find myself in this scenario where my CreateView, UpdateView and DeleteView are almost identical. Is there a way to implement this with only a single view CreateUpdateView or something like that or is this the standard way to implement CBGV's?

此外，在ThingyAdd中，我没有像在ThingyEdit中那样指定模型，但是它们都可以正常工作.我假设该模型是由form_class ThingyForm(是ModelForm)的元部分中定义的模型隐含/拾取的.这个假设正确吗?

Also, in ThingyAdd I haven't specified the model like I have in ThingyEdit, yet they both function fine. I'm making the assumption that the model is implied/picked-up by the model defined in the meta portion of the form_class, ThingyForm, which is a ModelForm. Is this assumption correct?

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/'

推荐答案

您可以创建另一个mixin

You could create another mixin

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

然后在您的视图中:

class ThingyAdd( AuthMixin, ThingyMixin, CreateView ):
  pass

class ThingyEdit( AuthMixin, ThingyMixin, UpdateView ):
  pass

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