django - 如何在基于函数的 View 而不是类中使用 Django Hitcount？

Question

该文档仅涵盖了 Django-Hitcount 在基于类的 View 中的使用。

from hitcount.views import HitCountDetailView

class PostCountHitDetailView(HitCountDetailView):
    model = Post        # your model goes here
    count_hit = True    # set to True if you want it to try and count the hit

有没有办法在函数中使用它？

Answer 1

有可能，你只需要实现 HitCountDetailView implements [GitHub]的逻辑即可。 .
因此，对于“命中”MyModel 的对象的基于函数的 View 这看起来像:

from hitcount.utils import get_hitcount_model
from hitcount.views import HitCountMixin

def some_view(request, pk):
    object = get_object_or_404(MyModel, pk=pk)
    context = {}

    # hitcount logic
    hit_count = get_hitcount_model().objects.get_for_object(object)
    hits = hit_count.hits
    hitcontext = context['hitcount'] = {'pk': hit_count.pk}
    hit_count_response = HitCountMixin.hit_count(request, hit_count)
    if hit_count_response.hit_counted:
        hits = hits + 1
        hitcontext['hit_counted'] = hit_count_response.hit_counted
        hitcontext['hit_message'] = hit_count_response.hit_message
        hitcontext['total_hits'] = hits

    # … extra logic …

    return render(request, 'my_template.html', context)

然而，这在某种程度上说明基于类的 View 更适合此类任务:人们可以轻松地在可重用组件中定义逻辑，从而将其混合到现有逻辑中。
