Issues with path() in urls.py in django 2.0.5 - python

I am trying to do the following thing in urls.py but Django 2.0.5 doesn't seem to support url(). Instead of it, I used path() but still, its throwing invalid syntax error.
Can someone give a clearer picture of path() as it seems to be not supporting regex.
Providing the code here:
from django.contrib import admin
from django.urls import path
from .views import home_page
urlpatterns = [
path('$', home_page)
path('admin/', admin.site.urls),
]

You miss a ,, and $ is unnecessary
from django.contrib import admin
from django.urls import path
from .views import home_page
urlpatterns = [
path('', home_page),
path('admin/', admin.site.urls),
]

Django2 has 2 functions for URLconfs, path(), re_path().
You can use regex paths (regular expression based paths) with re_path(), so remove $ and place , between two consecutive paths.
Note: Let suppose your app name is my_django_app created by python manage.py startapp my_django_app command.
I created a new Django app named my_django_app and tried, it works fine. I have the following code in my urls.py file.
"""my_django_proj URL Configuration

django 2.0 - including urls file from an app to the root urls file
Thanks.

If you prefer to use url instead of path, that will work just fine. You just have to import from django.conf.urls instead. So your import statement should look like this:
from django.conf.urls import url
Django says on their documentation page that this feature will likely be deprecated in future versions to re-path, however, url still works fine for me, and I'm running Django 2.0.7... so, I imagine it would work with yours as well. I guess because of this, with Django version 2 and above, it nows decides when it creates the boilerplate project that instead of importing urls from django.conf.urls, it imports path from django.urls. (Note: PATH doesn't allow for regex)
What I typically do, is create an app specific urls.py. In that urls.py I'll import url from django.conf.urls and have my specific app level urls there:
from django.conf.urls import url
from app_name import views # have to import views
urlpatterns = [
url(r'^$', views.index),
url(r'^users$',views.users),
]
Then in the project level urls.py I'll add the include module as so I can link it to my app specific urls.py file:
from django.conf.urls import url, include
from django.contrib import admin
from app_name import views
urlpatterns = [
url(r'^',include('app_name.urls')),
url(r'^admin/', admin.site.urls),
]
(Note: If you have a separate folder in between such that the folder structure looks something like mainproject>apps>app_name>(settings.py, views.py, admin.py etc...) you will have to create an __init__.py file in the apps folder as so Django can recognize the module.

urlpatterns = [
path('', home_page),
path('admin/', admin.site.urls)
]
As stated in the above answers, the $ is unnecessary while using path(). You are getting a syntax error due to the comma after admin.site.urls) which should be removed.

Django can't map url to view using include method

I have the following urls.py in my project dir,
Main project urls.py
from django.contrib import admin
from django.urls import path, include
from . import views
urlpatterns = [
path('', views.render_calculator, name='render_calculator'),
path('calculator/', views.render_calculator, name='render_calculator'),
path('disclaimer/', views.render_disclaimer, name='render_disclaimer'),
path('cookiepolicy/', views.render_cookiepolicy, name='render_cookiepolicy'),
path('privacypolicy/', views.render_privacypolicy, name='render_privacypolicy'),
path('dashboard/', views.render_dashboard, name='render_dashboard'),
path('about/', views.render_about, name='render_about'),
path('admin/', admin.site.urls),
path(r'^', include('accounts.urls'))
]
Now I created a new app accounts (I added it to my apps in settings.py) where I would like to store the urls of that app in its own dir like so:
Accounts app urls.py
from . import views
from django.urls import path
urlpatterns = [
path('register/', views.render_register, name='render_register'),
]
Accounts app views.py:
from django.shortcuts import render
def render_register(request, template="register.html"):
return render(request, template)
However, this configuration throws me this error:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/register
Using the URLconf defined in CFD.urls, Django tried these URL patterns, in this order:
[name='render_calculator']
calculator/ [name='render_calculator']
disclaimer/ [name='render_disclaimer']
cookiepolicy/ [name='render_cookiepolicy']
privacypolicy/ [name='render_privacypolicy']
dashboard/ [name='render_dashboard']
about/ [name='render_about']
admin/
^
The current path, register, didn't match any of these.
Where is the missing piece?
You are using path() with the regex r'^' which is causing your problem.
In order to define a path with a regex, you need to use re_path.
So change it to the following line:
re_path(r'^', include('accounts.urls'))
or you can use
path('', include('accounts.urls'))
Change this.
path(r'^', include('accounts.urls')) to
path('', include('accounts.urls'))

Django : Page not found (404) Why...?

I'm a beginner Django. So I read the tutorials and I'm following them.
But I'm receiving an Error page. 'What is the problem...?'
(I installed the python 3.6.5 version)
My error:
Using the URLconf defined in mysite.urls, Django tried these URL
patterns, in this order:
1.polls/
2.admin/
The empty path didn't match any of these.
polls/urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
]
polls/views.py
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world. You're at the polls index.")
And Finally!!
mysite/urls.py
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
]
But running python manage.py runserver gives this error:
Page not found !!, The empty path didn't match any of these!!!
So I need your help, plz help me....!!
I assume your mysite is the "Django project name", so it contains the root urls.py. If we take a look at the file, we see:
# mysite/urls.py
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
]
So that means that all the urlpatterns in the polls/urls.py are "sub URLs" of this path('polls/', ...), therefore you can say that the URLs in polls/urls.py are "prefixed" with 'polls/' implicitly.
In order to reach the index(..) view, we thus have to find a "path" from the root URLs to this specific view. The only way to reach this is first taking the 'polls/' path, and then selecting the '' path in polls/urls.py. The path is thus polls/.
So in order to "trigger" this view, you need to query a URL like:
https://localhost:8000/polls/
(of course if you have specified another port, or run the Django webserver on another server, you need to modify localhost, and 8000 accordingly).
I stumbled on this error and figured out that I misinterpreted the instruction at the top of page 18, section 2.3.4, listing 10. I modified that mysite/usrls.py file at the top level mysite directory, instead of the mysite/mysite/urls.py file. It worked fine after that.

Django 2.0.5 404 error-page not found

I am new in using Django and I am having some problems. When I run my server 'runserver' it shows 404 page not found. My project directory name is 'mysite' and my app name is 'webapp'. The problem I think is in 'urls' file. I have also put my app name in INSTALLED_APPS under the settings section.
This is the code in mysite/urls.py file:
"""mysite URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')

1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('admin/', admin.site.urls),
path('webapp', include("webapp.urls")),
]
And this is the code in webapp/urls.py file:
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name = "index"),
]
I am using the latest Django version 2.0.5, I have tried to look up for this error but most of them seems to be of the older versions of Django.
I would appreciate any help, in this problem.
In your webapp/urls.py, you have to specify app name like
app_name = "webapp"
mysite/urls
urlpatterns =
[
path('webapp/'), include() )
]
Note: parent urls must contain trailing slash.
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('admin/', admin.site.urls),
path('webapp/', include('webapp.urls')),
]
You forgot to add backslash after webapp in path "webapp/" which would help to redirect to further methods in views.
As nothing has been defined for your root URL,it is thus empty and the 404 error occurs.To solve it,simply type the path to your view after the local server URL in your address bar.i.e "127.0.0.1:8000/webapp" or use "localhost/name_of_url"

Django URL patterns not being read

So I am following a Django tutorial and I have reached the stage where I add my own URL patterns to the urls.py file.
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url((r'^webapp/', include('webapp.urls'))),
url(r'^admin/', admin.site.urls),
]
the problem is that when I run the server Django doesnt even search for the pattern. I'm not sure what I'm doing wrong here
webapp.urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.index, name='index'),
]
Make sure the directory structure is:
app
app
urls.py
webapp
urls.py
You write about a file named webapp.urls.py that is unusable by django
You pass wrong arguments for url().
Wrong:
url((r'^webapp/', include('webapp.urls')))
Right:
url(r'^webapp/', include('webapp.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.
