Page not found 404 - Django

I'm a newbie to Django and I know this probably has been asked alot of times.
So basically what's happening is when I try to create a new project and whenever I'm trying to run my server, by default it's opening http://127.0.0.1:8000/catalog/ and not http://127.0.0.1:8000/.
Even if I run the server with my other projects, I'm facing the same error.
I followed this django basics tutorial on https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/skeleton_website
Idk but somehow I think it's default address is set to http://127.0.0.1:8000/catalog/.
Here's the link to the repo for the project:
https://github.com/Fanceh/django-404-error
Here's my project's urls.py:
from django.contrib import admin
from django.urls import path, include
from testuapp import urls
urlpatterns = [
path('admin/', admin.site.urls),
path('',include("testuapp.urls"))
]
Here's the code in my testuapp urls.py:
from django.urls import path
from . import views
urlpatterns = [
path('', views.testu),
]
Here's my webapp's views.py file:
from django.shortcuts import render
# Create your views here.
def testu(request):
render(request, 'Greetings!')
Is there any way I can change it?
Regards

From the tutorial link it mentions the redirect.
Any request for the root URL, will redirect you to /catalog.
Screenshot from the tutorial below.
HTH

so i assume you are below url pattern structure in your testuapp project.
urlpatterns = [
path('catalog',include("views.catalog"))
]
views.calalog is the name of the method in your view file.

Ok I think I figured it out, it's just the chrome cache. I cleared it and bam it's working!

What is the url.py file that opens home using wagtail?

I'm starting using Wagtail + Django.
Generally, in Django you set the urls path in a urls.py file.
However, I cannot find the url.py that says to my app, when users visits main domain (local http://127.0.0.1:8000/) show home_page.html view.
I'm following the get_started tutorial.
And used this command to generate the basic apps:
wagtail start elim
This generated: a) elim, b) home, c) search apps.
Only elim app contains a urls.py, but it doesn't set a path for home:
from django.conf import settings
from django.conf.urls import include, url
from django.contrib import admin
from wagtail.admin import urls as wagtailadmin_urls
from wagtail.core import urls as wagtail_urls
from wagtail.documents import urls as wagtaildocs_urls
from search import views as search_views
urlpatterns = [
url(r'^django-admin/', admin.site.urls),
url(r'^admin/', include(wagtailadmin_urls)),
url(r'^documents/', include(wagtaildocs_urls)),
url(r'^search/$', search_views.search, name='search'),
]
This is my project structure:
So how does going to "/" open the home page???

The home dir is served by wagtail internal mechanism. Scroll to the end of the file elim/urls.py to find this :
urlpatterns = urlpatterns + [
# For anything not caught by a more specific rule above, hand over to
# Wagtail's page serving mechanism. This should be the last pattern in
# the list:
url(r"", include(wagtail_urls)),
# Alternatively, if you want Wagtail pages to be served from a subpath
# of your site, rather than the site root:
# url(r"^pages/", include(wagtail_urls)),
]
So, continue to read the tutorial, I'm sure you will soon or later discover the Page models and everything provided by wagtail.

Try adding a view function in your app's views.py file that renders home_page.html when the user goes to "/".
in views.py write this:
def home_page(response):
return render(response, "home/home_page.html")
then map this to ur urs.py file
url_patterns = [
path("", views.home_page)
]
then add this url to your url conf

Django Url Redirection

I have a problem with my project & I hope that you will help me figure it out.The main problem is that my project is a one-single page template, so I don't have so many views , but I want to know , how to redirect to my homepage
from django.conf.urls import url
from django.contrib import admin
from iubestete import views as iubestete_views
urlpatterns = [
url(r'^$', iubestete_views.index),
url(r'^',iubestete_views.index,name="portal"),
url(r'^admin/', admin.site.urls),
]
here is my urls.py file , which function should I import or what should I do? I mean, I want to know for example, if a person types "http://127.0.0.1:8000/adsnjiwadi/" ,how can I redirect that link to my homepage(index.html)?Thank you so much & I hope that you'll have a great day:) Peace:)

Your code url(r'^',iubestete_views.index,name="portal") in urls.py already catch all URL pattern, it will direct to your home page.
eg: http://127.0.0.1:8000/adsnjiwadi, http://127.0.0.1:8000/sfddasfdfaf/ddfsaf, etc. will go to your home page (index).

In your urls.py
url(r'^(?P<garbage>.*)/$', views.garbage,name='redirect')
In your views.py
from django.core.urlresolvers import reverse
def garbage(request, garbage):
return HttpResponseRedirect(reverse('index'))
This is is a hacky method. Anything other than your root url will return to index url.

Polls application -- django tutorial not working

I followed the instructions in the tutorial
I made one change for debugging, here are the files:
mysite1\urls.py:
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^abc/', include('polls.urls')),
url(r'^polls/', admin.site.urls),
url(r'^admin/', admin.site.urls),
]
File: mysite1\polls\urls.py
from django.conf.urls import url
from .import views
urlpatterns = [
url(r'^&', views.index, name='index'),
]
Now if I go to the site http://127.0.0.1:8000/polls/ then it shows the login page same as going to the site http://127.0.0.1:8000/admin/.
However, if I go to the site http://127.0.0.1:8000/abc/ it gives me the following:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/abc
Using the URLconf defined in mysite1.urls, Django tried these URL patterns, in this order:
^abc/
^polls/
^admin/
The current URL, abc, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
Can someone guide me what I am doing wrong?

In mysite1\polls\urls.py It should be
url(r'^$', views.index, name='index'),
Notice that your code had an & instead of $. $ indicates a end-of-string match character.

I had a few issues with this, maybe it'll help someone. My VS code was running python 2.7 so the first line on page urls.py in the web project folder (not the polls folder) I had to change to "django.conf.urls import include, url" from "from "django.urls import include, path". I had to include .conf. and urls, path was not working and it was not working without "conf".
Another issue I had on this same page is I had to correct it to "urlpatterns = [url('', include('hello.urls'))..." from "urlpatterns = [path('', include("hello.urls"))". Path was not working so I got this to work.
The third thing is, Notice that there is a '' in the code. It should be blank otherwise when you go to url http://127.0.0.1:8000/ it doesn't redirect to views.py in the polls folder.
I hope this helps someone. Thanks

Can't display new html page with href from homepage

The only examples I find. are related to issues with login page and iteration to other pages but not in the way I have the problem, so here is the issue I have to deal with -
I want to display a form for creating an account with multiple steps, using modals, when a user access the button "subscribe"
on my homepage.html I have this:
<a onClick="window.location.href='account'" target="_blank">
<input type="submit" value="account">
</a> `
...which is supposed to go to a new account.html page, in the same folder as my homepage.html
in my app's urls.py, where the apps' name is homepage I have:
from django.conf.urls import patterns, url
from homepage import views
urlpatterns = patterns('',
url(r'^$', views.homepage, name='homepage'),
url(r'^account$', views.account, name='account'),
)
and in my views I have:
from django.shortcuts import render
from homepage.models import Email
def tmp(request):
latest_email_list = Email.objects.order_by('-pub_date')[:0]
context = {'latest_email_list': latest_email_list}
return render(request, 'home_page/homepage.html', context)
def homepage(request):
return render(request, 'home_page/homepage.html')
def account(request):
return render(request, 'home_page/account.html')`
when I click on the button I get
Not Found
The requested URL /account was not found on this server.
I am a complete beginner in django and python so I really haven't yet wrapped my mind on how to work properly with the urls, views, and models together but I assume I have something wrongly defined in my views
would be grate if someone could help me setting this up,
Thanks

I only want to thank all those who took time to check my question and tried to give a solution.
I think it was my mistake that I did not post the code I have in my main urls.py file, so here it is:
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^$', include('home_page.urls', namespace="homepage")),
url(r'^admin/', include(admin.site.urls)),
)
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()
Apparently, the problem was in that first prefix of the first url in the list:
I changed
url(r'^$'
for
url(r''
and now it calls whatever links I provide in my html pages.
Thanks all again
