如何计算django中博客的观点

Question

我正在尝试计算我的Django项目中每个博客中的所有视图。最好的方法是什么？ （赦免错误）

假设您想在每次观众查看帖子时都可以更新帖子计数，这是您可以采用的一种方法。

您可以在 Post Model 上添加整数字段。查看该帖子后，可以更新帖子上的此字段。

您还可以在发布模型上添加方法，该模型每当被调用时都会专门更新视图计数，该视图计数可以允许从 hmtl 模板本身（不推荐），以及 views （是否CBV或FBV）。

在 models.py.py 文件中：

class Post(models.Model):
     ...
     views = models.IntegerField(default=0) # Upon creation the views will be 0
     ...

    # You can have
    def get_absolute_url(self):
         return reverse('post-details', kwargs={"id": self.id})

    # An alternative to use to update the view count 
    def update_views(self, *args, **kwargs):
         self.views = self.views + 1
         super(Post, self).save(*args, **kwargs)

在 app urls.py 文件

from app.views import PostDetailsView, post_details

urlpatterns = [
    ...
    # Using either of the following
    path('post-details/<int:id>/', PostDetailsView.as_view(), name='post-details'), # class-based view
    path('post-details/<int:id>/', post_details, name='post-details'), # function-based view 
    ...
]

中： views.pys.pys.py file：

# Class based view
class PostDetailView(DetailView):
     context_object_name = 'post'
     template_name = 'post-details.html'

     # Overriding the class get_object method
     def get_object(self):
          post_id = self.kwargs.get('id')
          post = get_object_or_404(Post, id=post_id)

          # Update the view count on each visit to this post.
          if post:
               post.views = post.views + 1
               post.save()
   
               # Or
               post.update_views()

          return post

    # You might have other methods in here if necessary
    ...

# Function based view
def post_detail(request, id):
     post = get_object_or_404(Post, id=id)

     # Update the view count on each visit to this post.
      if post:
           post.views = post.views + 1
           post.save()

           # Or
           post.update_views()

     ...

     context = {
          'post': post,
           ...
     }

     return render(request, "post-details.html", context)
