TypeError at /registration/login/ sequence item 0: expected string or Unicode, function found in Django 1.11

I am modifying Gitstack, a 32bit Python2.7-based Git Web Application (available here) for my 64bit Python installation.
In the process, I also had to modify all the Django codes e.g. urlpatterns, etc.
While I managed to adapt it to my Apache/PHP environment, I ended up with this Django issue.
The error is as below while trying to access /gitstack location
TypeError at /registration/login/

Request Method: GET

Django Version: 1.11.6

I could not make any useful insight from the traceback below with my little head. The traceback just ends inside Django which seems very little helpful.

Below is my modified app\urls.py:
from django.conf.urls import url, include
from django.contrib.auth.views import login
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()
urlpatterns = [
# Examples:
#url(r'^$', 'app.views.home', name='home'),
# url(r'^app/', include('app.foo.urls')),
# login
url(r'^registration/login/$', login, name=login),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
# url(r'^admin/', include(admin.site.urls)),
url(r'^gitstack/', include('gitstack.urls')),
# url(r'^rest/', include('rest.urls')),
]
Here is my modified gitstack/urls.py
from django.conf.urls import url, include
from .views import index, users, groups, repository_permission, add_repo_user_dialog, add_repo_group_dialog, group_user, add_group_user_dialog, settings_general, settings_authentication, settings_security, log_me_out
urlpatterns = [
# standard user interface
url(r'^$', index, name='index'),
url(r'^users/', users, name='users'),
url(r'^groups/', groups, name='groups'),
url(r'^repository/(?P<repo_name>.+)/permission/$', repository_permission, name='repository_permission'),
# add users dialog
url(r'^repository/(?P<repo_name>.+)/permission/adduser/$', add_repo_user_dialog, name= 'add_repo_user_dialog'),
url(r'^repository/(?P<repo_name>.+)/permission/addgroup/$', add_repo_group_dialog, name='add_repo_group_dialog'),
url(r'^group/(?P<group_name>.+)/user/$', group_user, name='group_user'),
# add users dialog (for the group)
url(r'^group/(?P<group_name>.+)/user/add/$', add_group_user_dialog, name='add_group_user_dialog'),
# settings tab
url(r'^settings/general/', settings_general, name='settings_general'),
url(r'^settings/authentication/', settings_authentication, name='settings_authentication'),
url(r'^settings/security/', settings_security, name='settings_security'),
url(r'^logout/', log_me_out, name='log_me_out'),
]

urlpatterns should be a Python list of url() instances. So you need to remove 'gitstack.views', from urlpatterns in gitstack/urls.py
UPD
Also you have problem with login pattern. Name should be string. Change url(r'^registration/login/$', login, name=login) to url(r'^registration/login/$', login, name='login')

Django accessing admin page and adding a new url - BEGINNER

I have created a DJango project in eclipse. Later i added a new application (R-CLick Project folder ---> DJANGO ---> Create application (manage.py startapp))
I names it Super.
Then again i created another new application (using the same steps described above), and named it Human.
In my project now, i have 2 applications created (In eclipse it appears as 2 packages).
I have a file called admin.py inside the package Super.
The code is as follows:
from django.contrib import admin
from Super.models import People
from Human.models import NormalHuman
admin.site.register(People)
admin.site.register(NormalHuman)
I even registered the 2 new applications in the Settings.py file.
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'Super',
'Human',
# Uncomment the next line to enable the admin:
'django.contrib.admin',
# Uncomment the next line to enable admin documentation:
# 'django.contrib.admindocs',
)
I also made changes to the urls.py file.
from django.conf.urls import patterns, include, url
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
from Human.models import NormalHuman
admin.autodiscover()
urlpatterns = patterns('',
# Uncomment the next line to enable the admin:
url(r'^admin/', include(admin.site.urls)),
url(r'^normal/', NormalHuman),
)
Problems i want to solve:
1.) After restarting the server, when i try to navigate to the url 127.0.0.1:9095/normal i end up in a 404
2.) I need to add NormalHuman to the admin page, so i have access to its content.

You have already registered admin url so you do not need to add
url(r'^normal/', NormalHuman),
to see content of NormalHuman model.
just simply hit 127.0.0.1:9095/admin/human/normalhuman to see content of NormalHuman model.

I am working off of the guide at http://net.tutsplus.com/tutorials/python-tutorials/python-from-scratch-creating-a-dynamic-website/
There seems to be some differences in his directory structure vs mine. I'm guessing something had changed in later django versions. I have never used django, just trying it out to see if it will work for a project. Any help would be much appreciated.

In urls.py
try these
url(r'^$', 'tickets.views.home', name='home'),
instead of these
url(r'^$', 'dcdev1.tickets.views.home', name='home'),
Also you can run python manage.py validate and maybe you will see something useful.

Django 1.4.1 not loading admin site (Django Book tutorial)

I can't figure out why Django is not loading the admin page. It seems like it isn't even reading the urls.py file that I am editing - because even if I comment out the 'urlpatterns' statement, it still loads the local hello page fine once I run the server.
This is the error message:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/admin
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
^hello/$
^time/$
^time/plus/(\d{1,2})/$
The current URL, admin, didn't match any of these.
This is my urlpatterns code:
from django.conf.urls import patterns, include, url
from mysite.views import *
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
('^hello/$', hello, ),
('^time/$', current_datetime, ),
(r'^time/plus/(\d{1,2})/$', hours_ahead, ),
# Examples:
# url(r'^$', 'mysite.views.home', name='home'),
# url(r'^mysite/', include('mysite.foo.urls')),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
url(r'^admin/', include(admin.site.urls))
)
And this is a snippet os my settings.py file:
MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
# 'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
# 'django.contrib.messages.middleware.MessageMiddleware'
# Uncomment the next line for simple clickjacking protection:
# 'django.middleware.clickjacking.XFrameOptionsMiddleware',
)
ROOT_URLCONF = 'mysite.urls'
# Python dotted path to the WSGI application used by Django's runserver.
WSGI_APPLICATION = 'mysite.wsgi.application'
TEMPLATE_DIRS = (
'/Users/pavelfage/Desktop/Coding/mysite/Templates',
# Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
)
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
# 'django.contrib.messages',
# 'django.contrib.staticfiles',
# Uncomment the next line to enable the admin:
'django.contrib.admin',
# Uncomment the next line to enable admin documentation:
# 'django.contrib.admindocs',
'mysite.books'
)
Any help much appreciated!

I faced same problem. Uncommenting from django.contrib import admin in urls.py solved the problem.

I had the same problem. You may try this:
In your urls.py replace the call include(admin.site.urls) by this: admin.site.urls
In your setting.py if don't have any TEMPLATE_CONTEXT_PROCESSORS property (that was my situation) add this:
TEMPLATE_CONTEXT_PROCESSORS = ("django.contrib.auth.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media", "django.core.context_processors.static", "django.core.context_processors.tz", "django.contrib.messages.context_processors.messages")
It seams to be roughly the default property in a normal django 1.4 configuration. Here are the docs talking about it: djangoproject-doc1 djangoproject-doc2
You may also have to uncomment the strings:
# 'django.contrib.messages',
# 'django.contrib.staticfiles',
in your INSTALLED_APPS property of the settings.py but i'm not sure about it.
Sorry about not explaining much better the reasons of those changes but I'm a django-beginner to. I just found your question corresponding to my problem and then a possible awnser.
I hope it may help you.
EDIT: as seen in a comment you may try to remove the url(...) instruction on the line concerning the url of the admin site

Can't get zinnia to work in my django application

Upon accessing the test server/weblog/ url on localhost, in an environment with "latest everything stable" (python 2.7, django 1.4.1, apache 2.2.22) I'm getting:
NoReverseMatch at /weblog/
Reverse for 'zinnia_entry_add' with arguments '()' and keyword arguments '{}' not found.
Request Method: GET
Request URL: http://127.0.0.1/weblog/
Django Version: 1.4.1
Exception Type: NoReverseMatch
Exception Value:

and from urls.py:

(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '/home/lastpixel/web/media', 'show_indexes': True}),
(r'^.*$', views.Index),
)
The application works otherwise (withouth the zinnia blog). Any idea what I might be doing wrong? Much appreciated!

I had a similar problem after updating zinnia.
This helped me out, although I didn't expect a solution in mysql:
First, edit /etc/my.conf
[client]
default-character-set=utf8
[mysqld]
default-character-set = utf8
skip-character-set-client-handshake
character-set-server = utf8
collation-server = utf8_general_ci
init-connect = SET NAMES utf8
Second, restart mysql
Taken from:
zinnia on github

It is likely that it is a namespace problem. In your error page, do you see the inline error highlight something that looks like {% block 'zinnia:zinnia_entry_add' %}? This is part of the zinnia name space, indicated by the zinnia: part of that definition. If you see something like this, you likely just need to add the correct namespace to your URLs:
urlpatterns = patterns('',
#.....
(r'^weblog/', include('zinnia.urls', namespace="zinnia")),
#.....
)
