I have tried importing from django.urls import include, re_path, however that could not solve my problem as it have solved for many in other threads..

Given below is my url file.. before if..

from django.conf import settings
from django.conf.urls.static import static 
from django.contrib import admin
from django.urls import path, include
from posts.views import (
    index, blog, post, search,
    post_update, post_delete, post_create)


urlpatterns = [
    path('admin/', admin.site.urls),
    path('', index),
    path('blog/', blog, name='post-list'),
    path('search/',search, name='search'),
    path('create/', post_create, name='post-create'),
    path('post/<id>/', post, name='post-detail'),
    path('post/<id>/update/', post_update, name='post-update'),
    path('post/<id>/delete/', post_delete, name='post-delete'),
    path('tinymce/', include('tinymce.urls')),
    path('accounts/', include('allauth.urls'))
]

I have been facing this problem while deploying my app on heroku, anyone can help on this?

Answer 1

The problem seems to be coming from tinymce, and it doesn't look like django-tinymce4-lite supports Django 4+ yet ( https://pypi.org/project/django-tinymce4-lite/ ).

The django-tinymce==3.5.0 package supports Django 4.0 and 4.1 ( https://pypi.org/project/django-tinymce/ ). You might want to try that...
