Django 4.2: Reverse URL Lookup scenarios for Namespaced App with Dynamic URL Parameters
I'm trying to configure I'm performance testing and I'm testing a new approach and I'm working on a project and hit a roadblock. I'm having trouble with reverse URL lookups in Django 4.2 when dealing with namespaced apps and dynamic URL parameters. I set up a nested URL configuration and expected the reverse lookup to work based on the namespaced path, but I'm getting a `NoReverseMatch` behavior. Here’s a simplified version of my `urls.py`: ```python # myapp/urls.py from django.urls import path from . import views app_name = 'myapp' urlpatterns = [ path('item/<int:item_id>/', views.ItemDetailView.as_view(), name='item_detail'), ] ``` And in my main `urls.py`, I included this app with a namespace: ```python # project/urls.py from django.urls import include, path urlpatterns = [ path('myapp/', include('myapp.urls', namespace='myapp')), ] ``` Now, when I try to perform a reverse lookup in my template using the following syntax: ```html <a href="{% url 'myapp:item_detail' item.id %}">View Item</a> ``` It raises the behavior: `NoReverseMatch at /myapp/item/1/ Reverse for 'item_detail' with arguments '(1,)' not found. 1 pattern(s) tried: ['myapp/item/<int:item_id>/\Z']`. I’ve double-checked that `item.id` is indeed an integer and corresponds to an existing `Item` object. I’ve also tried using the reverse function in the view like this: ```python from django.urls import reverse url = reverse('myapp:item_detail', args=[item.id]) ``` But the same `NoReverseMatch` behavior occurs. I’m not sure if I’m missing something in the URL configuration or if there’s a mistake in how I’m referencing the URL in my template. Any insights would be appreciated! Has anyone else encountered this? I'm working with Python in a Docker container on Linux. I recently upgraded to Python stable. My development environment is macOS.
