我正在尝试在 Django 应用程序中创建编辑产品功能，但当我尝试访问编辑产品页面时遇到
DoesNotExist这是我的视图功能：
@login_required
def edit_product(request, pid):
product = Product.objects.get(pid=pid)
if request.method == "POST":
form = AddProductForm(request.POST, request.FILES, instance=product)
if form.is_valid():
new_product = form.save(commit=False)
new_product.user = request.user # assuming there is a user field in the Product model
new_product.save()
form.save_m2m() # Save many-to-many relationships
return redirect("vendorpannel:dashboard")
else:
# Print form errors for debugging
print(form.errors)
else:
form = AddProductForm(instance=product)
context = {
"form": form,
"product": product,
}
return render(request, "vendorpannel/edit-product.html", context)
当我尝试访问编辑产品页面时，出现以下错误：
DoesNotExist at /vendorpannel/edit_product/11
Product matching query does not exist.
我检查了我的数据库，并且存在指定的
pid任何人都可以帮我找出问题并提出解决方案吗？

编辑：
urls.py：
from django.urls import path
from vendorpannel import views
app_name = 'vendorpannel'
urlpatterns = [
path('vendor_pannel1/', views.vendor_pannel1, name='vendor_pannel1'),
path('vendor_signup/', views.vendor_signup, name='vendor_signup'),

path('vendor_settings/', views.vendor_settings, name='vendor_settings'),
path('add_product/', views.add_product, name='add_product'),
path('edit_product/<pid>', views.edit_product, name='edit_product'),
