Description

Created a small app to make notes and initial test of AI LLM POC.

Entire app works as intended except when editing notes. Always throws a dreaded "NoReverseMatch" (added word doc of the entire error).
NOTE: I deleted the all the *.html files and views.py functions, urls.py etc. and started all over again copy and pasting the code from another app I have written and used many times. Basically only having to change the namespace, models info etc. Only this app (hyperapp) is having the issue.

The error is in edit_notes.html hx-post="{% url 'hyperapp:notes_submit' item.pk %}"

I will add the relevant code below for viewing.

urls.py

from django.urls import path, include
from django.contrib import admin
from django.contrib.auth import login, logout
from django.urls import reverse

from . import views

app_name = 'hyperapp'

urlpatterns = [

path("hyperapp/", views.hyperindex, name="hyperhome"),
path("add", views.add_notes_view, name="add_notes_view"),

]
htmxpatterns = [

path("delete/<int:pk>/", views.delete_notes_view, name="delete_notes"),
path('edit_notes/<int:pk>/', views.edit_notes, name='edit_notes'),
path('notes_submit/<int:pk>/', views.notes_submit, name='notes_submit'),
path('setOrderby/', views.setOrderby, name='setOrderby'),
path('search_results_view/', views.search_results_view, name='search_results_view'),

]
urlpatterns += htmxpatterns
