How to solve urls not found issue in django

I am building an app using django and notice that some new urls that i have created, the list is provided below are not being found.
I read somewhere that the slug might be the reason django cannot found the urls but i am not sure
main urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path(config("ADMIN_URL"), admin.site.urls),
path("", include("core.urls", namespace="core")),
]
application urls.py
from django.contrib import admin
from django.urls import path, include
from . import views
app_name = 'core'
urlpatterns = [
path('index/', views.index, name='index'),
path('home/', views.home, name='home'),
path('home/<slug:slug>/', views.user_lessons_details, name='user-lessons-details'),
path('home/join-transaction/', views.user_lessons_join_transaction, name='user-lessons-join-transaction'),
path('home/start-transaction/', views.new_test_epoint, name='new-test-epoint'),
path('home/draft/<slug:slug>/', views.user_lessons_core_action, name='user-lessons-draft'),
path('teachers/lessons/create/', views.merchant_lessons_create, name='teachers-lessons-create'),
path('teachers/lessons/list/', views.teachers_lessons_list, name='teachers-lessons-list'),
path('teachers/lessons/<slug:slug>/', views.teachers_lessons_details, name='teachers-lessons-details'),
path('teachers/lessons/<slug:slug>/update/', views.teachers_lessons_update, name='teachers-lessons-update'),
path('teachers/lessons/<slug:slug>/delete/', views.teachers_lessons_delete, name='teachers-lessons-delete'),
path('teachers/drafts/create/', views.teachers_core_actions_create, name='teachers-drafts-create'),
path('teachers/drafts/list/', views.teachers_core_actions_list, name='teachers-drafts-list'),
path('teachers/drafts/<slug:slug>/', views.teachers_core_actions_details, name='teachers-drafts-details'),
path('teachers/drafts/<slug:slug>/update/', views.teachers_core_actions_update, name='teachers-drafts-update'),
path('teachers/drafts/<slug:slug>/delete/', views.teachers_core_actions_delete, name='teachers-drafts-delete'),
path('teachers/home/list/', views.teachers_home_list, name='teachers-home-list'),
path('teachers/home/<slug:slug>/', views.teachers_home_details, name='teachers-home-details'),
path('teachers/home/create/course/', views.teachers_home_transaction_quote, name='teachers-home-create-course'),
path('teachers/home/create/something/', views.teachers_home_create_transaction, name='teachers-home-create-something'),
path('teachers/home/create/fields-selection/', views.teachers_home_fields_selection, name='teachers-home-fields-selection'),
# ALL THE NEW URLS BELOW return NOT FOUND in django no matter what i do
path('teachers/home/account/settings/', views.teachers_settings, name='teachers-settings'),
path('teachers/account/settings/update-password/', views.teachers_settings_update_password, name='teachers-settings-update-password'),
path('teachers/account/payments/', views.teachers_payments, name='teachers-payments'),
path('teachers/account/payments/update/', views.teachers_payments_update, name='teachers-payments-update'),
path('teachers/account/analytics', views.teachers_analytics_stuff, name='teachers-analytics-stuff')
]
How can i possibly solve this urls not found issue in django?
Please dont mind the urls meaning

Problems in Django

I don't know why this problem happened.enter image description here
These errors occur when you read a book and follow it. I don't know what to do. Give me a hand.
Source Code
This is my fistsite.py source code.
fistsite.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
enter code here
path('admin/', admin.site.urls),
path('polls/', include('polls.urls')),
]
After changing the source code above
now fistsite.py
from django.contrib import admin
from django.urls import path, include
from . import views
urlpatterns = [
path('', views.index, name='index'),
path('/polls', views.polls, name='polls'),
path('/admin', views.admin, name='admin')
]
But there was an error.enter image description here
my projcetenter image description here

Assuming that you have Django version > 2.0, you should add to your urls.py file something like this:
from django.contrib import admin
from django.urls import path, include
from . import views
urlpatterns = [
path('', views.index, name='index'),
path('/polls', views.polls, name='polls'),
path('/admin', views.admin, name='admin')
]

So as shown in the error page, your Django project tried to go to localhost:8000/admin/ and localhost:8000/polls/ but the site you are trying to access in localhost:8000/ . You haven't defined any url pattern for capturing this scenario. What you can do is in your urls.py, add this line under urlpatterns :
urlpatterns=[
path('', views.index, name='index'),
...............
]
This works if you are using Django version>2.0
If you are using Django version<2.0 then you can add this:
urlpatterns=[
url(r'^$', views.index, name='index'),
...............
]

If you want to access you "polls". After change your fistsite.pytry this
url = "localhost:8000/polls/
and you are giving only localhost:8000 if did not create any app then this url will work.

I get this error when I run python manage.py

So I am working with Django. After setting up my URLs in both applications, I get this error when I run python manage.py migrate:
"file "C:\Users\Eric\Anaconda3\envs\myDjangoEnv\lib\site
packages\django\urls\resolvers.py", line 542, in url_patterns raise
ImproperlyConfigured(msg.format(name=self.urlconf_name))
django.core.exceptions.ImproperlyConfigured: The included URLconf 'alerts.urls' does not appear to have any
patterns in it. If you see valid patterns in the file then the issue
is probably caused by a circular import".
However, when I comment out include in my alerts.urls file it works fine. How can I fix this? I have attached my urls.py files.
This is my accounts.urls file:
from django.urls import path from django.contrib.auth import views as auth_views from . import views
app_name = 'accounts'
urlpatterns = [
path('login/',auth_views.LoginView.as_view(template_name='accounts/login.html'), name ='login'),
path('logout/', auth_views.LogoutView.as_view(), name ='logout'),
path('signup/', views.SignUp.as_view(), name ='signup'),
]
This is my main alerts urls.py file:
from django.contrib import admin
from django.urls import include,path
from django.urls import path,include from . import views
urlpatterns = [
path('', views.HomePage.as_view(), name="home"),
path('admin/', admin.site.urls),
path('test/', views.TestPage.as_view(), name="test"),
path('thanks/', views.ThanksPage.as_view(), name="thanks"),
path('accounts/', include("accounts.urls", namespace="accounts")),
path('accounts/', include("django.contrib.auth.urls")),
]

Why am I getting a 404 error when trying to access my website's domain name, yet if I domain name/home it works?

Okay... let's try to explain things clearly. I've used Python Django to create a dynamic webpage/web-app. After completing the website I have published it using DigitalOcean and have successfully attached my purchased domain name to the name server of DigitalOcean. When I access my website, ordinanceservices.com, i get an error 404; however, if I type ordinanceservices.com/home it works as it should and displays the home page. How, by editing the python files, can I have it to where ordinanceservices.com will display the home page as opposed to error 404? I feel like there's something that I am doing that is fundamentally wrong regarding my .urls structure and thus a rewrite/redirect in the nginx config should not be necessary.
Here is the specific error:
Page not found (404)
Request Method: GET
Request URL: http://ordinanceservices.com/
Using the URLconf defined in django_project.urls, Django tried these URL patterns, in this order:
^admin/
^ ^home/ [name='home']
^ ^contact/ [name='contact']
^ ^services/ [name='services']
The current URL, , didn't match any of these.
I somewhat understand what is happening here though I do not know how to fix this. Next I will provide my .urls files for each folder that contains such:
/django_project urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^', include('company.urls')),
)
/company urls.py
from django.conf.urls import url, include
from . import views
urlpatterns = [
url(r'^home/', views.home, name='home'),
url(r'^contact/', views.contact, name='contact'),
url(r'^services/', views.services, name='services'),
]
/company views.py
from django.shortcuts import render
def home(request):
return render(request, 'company/home.html')
def contact(request):
return render(request, 'company/contact.html')
def services(request):
return render(request, 'company/services.html')
What I am aiming to do, without needing to redirect the main URL using the nginx config files to do so, is to edit my urls and views structure of my Python files to ensure that the normal URL, ordinanceservices.com, will actually display a page; preferably the home page of my webpage.
I have a hunch that it has to do with the fact that I do not have a views.index for the r'^admin/' to reach to. I am not certain but I have been trying to figure this out for hours. Does anyone have a clue what I can do to fix this?

You haven't defined anything at the root url. Add one more line to your company urls.py so it becomes
//company urls.py
from django.conf.urls import url, include
from . import views
urlpatterns = [
url(r'^$', views.home, name='home'),
url(r'^home/', views.home, name='home'),
url(r'^contact/', views.contact, name='contact'),
url(r'^services/', views.services, name='services'),
]

First of all, check if you have added www.yourdomain.com or yourdomain.com to ALLOWED_HOST = ['www.yourdomain.com','yourdomain.com'] in your settings.py
and then in your company/urls.py do this
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.home, name='home'),
url(r'^contact/$', views.contact, name='contact'),
url(r'^services/$', views.services, name='services'),
]
and in your main urls.py add this code
from django.conf.urls import url,include
from django.contrib import admin
admin.autodiscover()
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^', include('company.urls')),
]

<module 'myblog.urls' from 'path\\to\\python\\file\\urls.py'>' is not a callable or a dot-notation path

I have this code in one file called urls.py
from django.conf.urls import url
from django.contrib import admin
from myblog import urls
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'', urls),
]
Im trying to redirect to another file in a module called myblog which contains another file called urls.py with the following code:
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.post_list, name='post_list'),
]
my views file which contains post_list method is as follows:
from django.shortcuts import render
def post_list(request):
return render(request,'myblog/post_list.html', {})
The result is that i keep getting the following error message:
module 'myblog.urls' from 'path\to\python\file\urls.py' is not a callable or a dot-notation path
Can anyone please explain to me where i am getting it wrong. I am new to django and python and i am using a tutorial from DjangoGirls.com. They use Django 1.8 and i have Django 1.9 installed.

Looking at the tutorial, uou can see that you have forgotten to use include.
First you have to add the import
from django.conf.urls import include, url
Then change the url pattern to:
url(r'', include('blog.urls')),
Be careful that you are using the correct module name - you have myblog, but the tutorial has blog.

You need to include the urls.py to link them
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'', include(urls, namespace='MyOtherapp')),
]
Note: I've also added a namespace here, its not required, it just helps when your using the url template tag.
