How to resolve recursion error in python django urls.py - django

Question

I'm pretty new to django and working on a project from https://github.com/mkaykisiz/DjangoS3Browser/ where I'm ending up with recursion error after adding "url(r'^' + settings.S3_BROWSER_SETTINGS + '/', include('djangoS3Browser.s3_browser.urls'))," line to url.py
Project structure:
I've the views under s3_browser dir and hence imported the same Can you correct me?Below is my project structure:
└───djangoS3Browser

You are importing wrong settings and views file. Just modify your code like:
from django.conf import settings
from django.conf.urls import url, include
from django.conf.urls.static import static
from your_app import views
import sys
urlpatterns = [
url(r'^get_folder_items/(.+)/(.+)/$', views.get_folder_items, name='get_folder_items'),
url(r'^upload/$', views.upload, name='upload'),
url(r'^create_folder/$', views.create_folder, name='create_folder'),
url(r'^download/$', views.download, name='download'),
url(r'^rename_file/$', views.rename_file, name='rename_file'),
url(r'^paste_file/$', views.paste_file, name='paste_file'),
url(r'^move_file/$', views.move_file, name='move_file'),
url(r'^delete_file/$', views.delete_file, name='delete_file'),
url(r'^' + settings.S3_BROWSER_SETTINGS + '/', include('djangoS3Browser.s3_browser.urls')),
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
EDIT: Instead of copying to your workspace, you need to install djangoS3Browser via pip and add it to your existing project. As in their github repo:
Just add as an application to a Django project, add some settings, and you'll be able to browse cloud containers and implied subdirectories, as well as view / download objects.
So you need to create a project in django by using django-admin startproject mysite command, then import djangoS3Browser as an app.
