基於類的通用視圖和DRY

Question

我在Django 1.3中實現基於類的視圖，我發現自己在這種情況下，我的CreateView，UpdateView和DeleteView幾乎完全相同。有沒有一種方法來實現這隻有一個視圖CreateUpdateView或類似的東西，或者這是實現CBGV的標準方式？

另外，在ThingyAdd中，我沒有指定像ThingyEdit那樣的模型，但它們都運行良好。我假設模型是由form_class的元部分ThingyForm定義的模型來暗示/拾取的，該模型是ModelForm。這個假設是否正確？

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/' 

Answer 1

你可以創建另一個混入

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

然後在您的觀點：

class ThingyAdd(AuthMixin, ThingyMixin, CreateView): 
    pass 

class ThingyEdit(AuthMixin, ThingyMixin, UpdateView): 
    pass 

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