找不到页面 (404) 添加评论

Question

大家好，我正在尝试对我的 django 项目添加评论，但出现 404 错误，我不知道这是为什么 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

您是否在数据库中创建了任何评论？
