找不到页面404添加评论

如何解决找不到页面404添加评论

嗨，我正在尝试在django项目中添加评论，但出现404错误，我不知道为什么 这是我的代码：

urls.py

    re_path(r'(?P<slug>[-\w]+)/',views.details,name="details"),path('comment/<prId>)',views.comment,name='comment'),

views.py

def details(request,slug):
    pr = get_object_or_404(Product,slug=slug)
    category = Category.objects.all()
    id1 = pr.category.id
    similar = Product.objects.filter(category_id=id1)
    pr.view = F('view')+1
    pr.save()
    context = {
        'products': pr,'similar' : similar,'category' : category
    }
    return render(request,"prDetails.html",context)

def comment(request,prId):
    pr = get_object_or_404(Product,id=prId)
    pr2 = pr.slug

    cm = Comment(
        name=request.POST.get('name',''),email=request.POST.get('email',text=request.POST.get('text',products=pr
    )
    cm.save()
    return HttpResponseRedirect(reverse('details',args=(pr2,)))

这是我的错误

Page not found (404)
Request Method: POST
Request URL:    http://127.0.0.1:8000/comment/1/
Raised by:  main.views.details
No Product matches the given query.

解决方法

def comment(request,prId):
    pr = get_object_or_404(Product,id=prId)

您是否在数据库中创建了任何注释？
