使用django开发博客过程记录5——日期归档和视图重写

针对每条博客的观看次数我么是使用django的Mixin实现的：

    def get(self, request, *args, **kwargs):
        last_visit = request.session.get(‘last_visit‘)
        reset_last_visit_time = False

        if last_visit:
            last_visit_time = datetime.datetime.strptime(last_visit[:-7], "%Y-%m-%d %H:%M:%S")

            if (datetime.datetime.utcnow() - last_visit_time).seconds > 0:
                obj = super(ArticleDetailView, self).get_object()
                obj.views = obj.views + 1
                obj.save()
                reset_last_visit_time = True
        else:
            reset_last_visit_time = True

        if reset_last_visit_time:
            request.session[‘last_visit‘] = str(datetime.datetime.utcnow())

        return super(ArticleDetailView, self).get(request, *args, **kwargs)

而根据日期归档则比较麻烦，借鉴了mysql必知必会得到了思路代码如下：

class DateView(ListView):
    template_name = ‘apps/full-width.html‘
    context_object_name = ‘article_list‘
    paginate_by = 10

    def get_queryset(self):
        year = self.kwargs[‘year‘]
        month = self.kwargs[‘month‘]
        start_date = datetime.date(int(year), int(month), 1)
        end_date = datetime.date(int(year), int(month), 31)
        article_list = Article.objects.filter(create_time__range=(start_date, end_date))

        return article_list
