大家晚上好，我是 Django 的初学者，我有博客页面详细信息，其中包含博客文章的浏览次数和类别以及博客文章标签和其他人员
我的帖子模型是:
class Post(models.Model):
title = models.CharField(max_length=250)
content = RichTextUploadingField()
post_date = models.DateTimeField(auto_now=True)
slug = models.SlugField(max_length=200, unique=True)
image = models.ImageField(null=True, blank=True, upload_to="images/")
tagss = models.ManyToManyField(Tags, blank=True, related_name='post')
Categorys = models.ManyToManyField(Category, blank=True, related_name='post')
views_count = models.IntegerField(default=0, null=True, blank=True)
def __str__(self):
return self.title
我的观点是:
def post_page(request, slug):
post = Post.objects.get(slug = slug)
post.views_count = post.views_count + 1
post.save()
print("views:", post.views_count )
cats = Category.objects.all()
tags = Tags.objects.all()
# change 2 to how many random items you want
random_items = list(Post.objects.all().order_by('?')[:2])
related_posts = list(
Post.objects.filter(
Q(tagss__name__in=[tag.name for tag in post.tagss.all()]) |
Q(Categorys__name__in=[Category.name for Category in post.Categorys.all()])
).distinct()
)
recent_posts = Post.objects.all().order_by('-id')[:4]
context = {'post': post, 'cats': cats, 'tags': tags, 'recent_posts': recent_posts,
'random_blog': random_items, 'related_posts': related_posts}
return render(request, 'blog/Blog_details.html', context)
这是我的 url.py
from . import views
from django.urls import path
urlpatterns = [
path('blog', views.blogs, name='blog'),
path('blog/<slug:slug>', views.post_page, name= 'blog_page')
这是我的模板:

我的问题是，当我刷新帖子页面时，浏览量增加 2，当用户刷新页面时，我需要增加 1 谢谢大家
最佳答案
问题在于调用 post_view() View 函数两次。有一些常见情况会导致该问题:
- 当现代浏览器同时发送“OPTIONS”和“GET”请求时，您的 post_view() 函数可能会被触发。您可以更改代码，仅处理“GET”请求:
def post_page(request, slug):
post = get_object_or_404(Post, slug=slug) # This is a cleaner way to get the object or 404
if request.method == 'GET':
# Increment view count only if the request is a GET request
Post.objects.filter(slug=slug).update(views_count=F('views_count') + 1)
post.refresh_from_db() # Refresh the instance after the update
... rest of your code ...
return render(request, 'blog/Blog_details.html', context)
关于Django 为什么我的 post.count_views 增加了 2？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/77466905/
