訪問到父母的變量

Question

我有一個從基類繼承兩個基於類的觀點：

class Base(object): 
    context_object_name = "book_list" 
    model = Book 
    def get_context_data(self, **kwargs): 
     context = super(Book, self).get_context_data(**kwargs) 
     return context 
    def get_queryset(self): 
     book_set = Book.objects.all() 
     return book_set 

class C1(Base ,ListView): 
    paginate_by = 20 
    template_name = 'sl/v1.html' 

class C2(Base, View): 
    template_name = 'sl/v2.html' 

我需要做一些工藝上的查詢集結果C2類裏面。那麼我怎樣才能訪問C2中的book_list？

Answer 1

class C2(Base, View): 
    template_name = 'sl/v2.html' 

    def get_queryset(self): 
     qs = super(C2, self).get_queryset() 
     # do something 

     return qs
