Django/Python中NoReverseMatch错误求助：新增数据后无法正常展示

我是Django和Python新手，开发资产管理功能时，想实现新增数据后在表格中展示，但出现了NoReverseMatch错误，自己排查不出代码问题，附上相关代码及错误截图，请求帮助解决。

错误截图：

Urls.py #

from django.urls import path, re_path
from django.conf import settings
from . import views
from django.conf.urls.static import static

urlpatterns =[
path('',views.index, name='index'),
re_path('<int:am_ast>', views.view_asset, name='view_asset'),
path('add/', views.add_asset, name='add_asset',) 
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) 

views.py #

    return render(request, 'assetmanagement/index.html', {
        'assets': asset.objects.all()
    })

def view_asset(request, am_ast):
    ast = asset.objects.get(pk=am_ast)
    return HttpResponseRedirect(reverse('index'))

def add_asset(request):
    if request.method == 'POST':
        form = assetform(request.POST)
        if form.is_valid():

            new_am_ast = form.cleaned_data['am_ast']
