使用基于Django类的视图生成PDF

Question

我目前有一个使用基于类的视图实现的图书馆借阅模板。实现是可能的东西，我们以前见过：

在urls.py：

#PK is the member ID 
url(r'^library/generate_loan_slip/(?P<pk>(\d+))/(?P<loan>(\d+))/' 
     ,LoanSlipDetailView.as_view() 
     , name='library_app_generate_loan_slip'), 

在views.py：

class LoanSlipDetailView(DetailView): 
    model = LibraryMember 
    loan = None 
    template_name = 'loan-slip.html' 

    def get_context_data(self, **kwargs): 
     context['loan'] = self.loan 
     context['member'] = member 
     return context 

    def get_object(self): 
     member = self.model.objects.get(pk=self.kwargs['pk']) 
     self.loan = LibraryLoan.objects.get(pk=self.kwargs['loan'], for_member=member) 
     return member 

而在HTML，loan-slip.html，与所有所需的变量HTML {{}}和使用{% if %} ... {% else %} ... {% endif %}和{% for ... %} ... {% endfor %}的对照。

现在，我想让响应生成PDF视图。到目前为止，我已经检查出reportlab，并且他们实现了基于功能的视图。但是，基于类的视图有没有实现？

您可以重写DetailView的get方法并在那里写入reportlab逻辑。
