使用session统计pageviews django detailview

Question

我正在计算视图的访问次数。我希望每次有人调用视图时计数器都会增加 1。然后，我希望模型上的 "visits" 字段自动更新为最新计数。但是，我不确定如何实现它。使用我发现的一些代码，我正在尝试这样做：

models.py

class Statute(models.Model):
    address = models.ForeignKey(Address,
                                null = True)
    statute_name = models.CharField(max_length=25,
                                    default='')
    category = models.CharField(max_length=55,
                                default='')
    section_number = models.CharField(max_length=55,
                                    default='')
    section_title = models.CharField(max_length=255,
                                        default='')
    timestamp = models.DateTimeField(editable=False)
    visits = models.IntegerField(default=0)
    content = models.TextField(default='')

    slug = models.SlugField()

views.py

def get_context_data(self, **kwargs):
        context = super(LibraryInStateView, self).get_context_data(**kwargs)
        state = State.objects.get(slug=self.kwargs.get('state'))
        statute = Statute.objects.all()
        context['latest_statutes'] = statute.filter(
                address__zipcode__city__county__state=state).order_by(
                '-timestamp')
        context['statute_count'] = Statute.objects.filter(
                address__zipcode__city__county__state=state).count()    
        context['view_count'] = self.request.session['visits']+1
        return context

Answer 1

在您看来更新：

statute = Statute.objects.filter(address__zipcode__city__county__state=state)
statute.visits += 1
statute.save()
context['statute_count'] = statute

Answer 2

您可以将其包含在 LibraryInStateView

的 .get_object() 方法中

def get_object(self):
    statute = super().get_object()
    statute.visits += 1
    statute.save()

    self.view_count = statute.visits
    return statute

或获取方法：

def get(self, request, *args, **kwargs):
    statute = # ... code to retrieve Statute for this view
    statute.visits += 1
    statute.save()

    self.view_count = statute.visits
    return super().get(request, *args, **kwargs)

然后将 view_count 附加到 class 实例后，您可以将其添加到上下文中：

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