NameError name 'Views' is not defined - django

from django.conf.urls import url, patterns, include
from django.contrib import admin
from django.views.generic import TemplateView
from collection import *
#from collection.views import index,thing_detail,edit_thing
urlpatterns = [
url(r'^$', views.index, name='home'),
url(r'^about/$',TemplateView.as_view(template_name='about.html'),name='about'),
url(r'^contact/$',TemplateView.as_view(template_name='contact.html'),name='contact'),
url(r'^things/(?P<slug>[-\w]+)/$', 'views.thing_detail' ,name='thing_detail'),
url(r'^things/(?P<slug>[-\w]+)/edit/$', 'views.edit_thing',name='edit_thing'),
url(r'^admin/', include(admin.site.urls)),
]
After running the server there is an error "NameError: name 'views' is not defined"
Any help ??

You aren't importing your own views.
Try adding this to your urls.py:
from . import views
Or if you are importing them from a specific app, try replacing . with the app name

First thing I notice is the import *, realize that this will/can cause confusion for other Developers reading your scripts. Python has a methodology that insists that explicit is better than implicit. Which in this senario means you should be explicit about what you are importing.
from django.conf.urls import url, patterns, include
from django.contrib import admin
from django.views.generic import TemplateView
from collection import views as collection_views
urlpatterns = [
# Function Based Views
url(r'^$', collection_views.index, name='home'),
url(r'^things/(?P<slug>[-\w]+)/$', collection_views.thing_detail ,name='thing_detail'),
url(r'^things/(?P<slug>[-\w]+)/edit/$', collection_views.edit_thing,name='edit_thing'),
# Class Based Views
url(r'^about/$',TemplateView.as_view(template_name='about.html'),name='about'),
url(r'^contact/$',TemplateView.as_view(template_name='contact.html'),name='contact'),
# Admin
url(r'^admin/', include(admin.site.urls)),
]
Here instead of importing everything from collection I'm importing just your views and assigning them to a variable. Then using that variable in the URL definitions.

Be sure to import your views by
specifying its location and the methods inside the view to be imported on your urls.py.
from . collection import *
(line above means from current location find collection.py and import everything on it)
Happy coding!

django rest framework "ModuleNotFoundError: No module named 'router'"

i have imported all the restframework packages but i don't understand why am i getting this strange error
from django.conf.urls import *
from django.contrib import admin
from django.views.generic.base import TemplateView
from .views import Create,Home,signup,Search,QuestionViewSet
from django.urls import reverse
from .models import Question
from django.contrib.auth import views as auth_views
from rest_framework import routers
router=routers.DefaultRouter()
router.register(prefix='question1',viewset=QuestionViewSet)
app_name='main'
urlpatterns = [
# url(r'^/',views.home,name='home'),
url(r'^home/',Home,name='home'),
url(r'^ques/',Create.as_view(success_url="/index/home/"),name='ques'),
url(r'^signup/',signup,name='signup'),
url(r'^logout/$', auth_views.logout,name='logout'),
url(r'^search/',Search,name='search'),
url(r'^api/', include('router.urls'))
# CreateView.as_view(model=myModel, success_url=reverse('success-url'))
]
this is the issue i'm facing
ModuleNotFoundError: No module named 'router'
any kind of help is appreciated
thanks in advance
First argument of include method can be module name or pattern list. Since router.urls is patterns list it should be
url(r'^api/', include(router.urls))
instead of
url(r'^api/', include('router.urls'))
So you need to remove '' signs.

NameError: name 'hello_world' is not defined

Using pycharm community python3.6.2 Django 2.0.3
views.py
from django.http import HttpResponse
def hello_world(request):
return HttpResponse('Hello World')
urls.py
from django.conf.urls import url
from django.contrib import admin
from . import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^$', views, hello_world),
]
i Tried to figure it out but missing something.
error while running on pycharm
urls.py", line 8, in
url(r'^$', views, hello_world),
NameError: name 'hello_world' is not defined
The error is telling you that there is no variable such as hello_world defined. You need to change it to:
url(r'^$', views.hello_world)
Where views is the views module that you have imported at the top.
This line of code is wrong
url(r'^$', views, hello_world)
You just imported the view which is the file view.py. Now you need to call the function view, which it is going to be like:
url(r'^$', views.hello_world)
And you might think it is going to be useful to give that url a name so you can use it as a reference in your templates in the future.
url(r'^$', views.hello_world, name='hello-world')
Also, you can import your view.py as follow:
from .views import hello_world
The next is possible as well as suggested in the comments Niayesh Isky, but not encouraged.
from .views import *

How would I write this url pattern in python 3.6/django1.11? (it is currently in python 2.7/django1.7)

I am very new, and I am doing a tutorial, that is a little bit old. I keep getting an error that this cannot import name 'patterns' then something about include, then syntax and so on. So what is wrong this section? How would I write it current day? Thank you for your time.
from django.conf.urls import patterns, include, url
from django.contrib import admin
from djangonote.views import home_view
urlpatterns = patterns('',
url(r'^$', home_view, name='home'),
url(r'^notes/', include('notes.urls', namespace='notes')),
)
The reply below fixed that issue, thank you Exprator!
I now get the issue:
NameError: name 'notes' is not defined.
What does that mean?
Ty for your time.
from django.conf.urls import include, url
from django.contrib import admin
from djangonote.views import home_view
urlpatterns = [
url(r'^$', home_view, name='home'),
url(r'^notes/', include('notes.urls', namespace='notes')),
]

Django URL mapping - NameError: name X is not defined

[A similar question was asked, but not marked as answered, here. I considered continuing that thread but the website told me I'm only supposed to post an answer, so it seems I have to start a new topic.] I'm trying to follow this tutorial and I'm having problems with the URL mapping. Specifically with the part described as "So best practice is to create an “url.py” per application and to include it in our main projects url.py file". The relevant, I hope, part of the folder structure, which arose by following steps of the tutorial to the letter (if possible; usage of the 'patterns' module was impossible for example) and using Django 1.10 is the following:
myproject/
myapp/
urls.py
views.py
myproject/
urls.py
The myproject/urls.py is as follows:
from django.conf.urls import include, url
from django.contrib import admin
admin.autodiscover()
from myapp.views import hello
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^myapp/', include(myapp.urls)),
]
The myapp/urls.py is as follows:
from django.conf.urls import include, url
urlpatterns = [
url(r'^hello/', myapp.views.hello),
]
The myapp/views.py is as follows:
from django.shortcuts import render
def hello(request):
return render(request, "hello.html", {})
However, running 'python manage.py runserver' results in the following error:
url(r'^myapp/', include(myapp.urls)),
NameError: name 'myapp' is not defined
INSTALLED_APPS in settings.py contains 'myapp'.
I'd be greatful for any tips on how to deal with the NameError! [Or any tips whatsoever that anyone might consider to be helpful!]
You have the NameError because you are referencing myapp in myproject/urls.py but haven't imported it.
The typical approach in Django is to use a string with include, which means that the import is not required.
url(r'^myapp/', include('myapp.urls')),
Since you have move the hello URL pattern into myapp/urls.py, you can remove from myapp.views import hello from myproject/urls.py.
Once you've made that change, you will get another NameError in myapp/urls.py. In this case, a common approach is to use a relative import for the app's views.
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^hello/$', views.hello),
]
Make sure you have imported following modules to urls.py.
from django.conf.urls import url
from django.contrib import admin
in django 2.0
use these
from django.contrib import admin
from django.urls import path
from first_app import views
urlpatterns = [
path('',views.index, name="index"),
path('admin/', admin.site.urls),
]
your app URL has to be a string
so, here is how the code should look like.
from django.conf.urls import include, url
from django.contrib import admin
admin.autodiscover()
from myapp.views import hello
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^myapp/', include('myapp.urls')),
]
also, note that from python 2 upward the regular expression is not needed.
change URL to path
from django.conf.URLs import include path
from Django.contrib import admin
admin.autodiscover()
from myapp.views import hello
urlpatterns = [
path('^admin/', include(admin.site.urls)),
path('^myapp/', include('myapp.urls')),
]
In Django 2.1.7 here is the default urls .py file
from django.contrib import admin
from django.urls import path
urlpatterns = [
path('admin/', admin.site.urls),
]
so we need to add this line as well
from django.conf.urls import url
I have followed #Alasdair answers
You have the NameError because you are referencing myapp in myproject/urls.py but haven't imported it.
The typical approach in Django is to use a string with include, which
means that the import is not required.
Unfortunately, it didn't work out(I still got the name X is not defined error). Here is how I do it.
from django.contrib import admin
from django.urls import include
from django.conf.urls import url
from article import urls as article_users
from article import urls as user_urls
urlpatterns = [
path('admin/', admin.site.urls),
path('api/article/', include(article_users)),
path('api/user/', include(user_urls)),
]
Before using the URL command be sure to first import the url from the module Urls. Then try using the runserver.
from django.conf.urls import url
from django.contrib import admin
from django.urls import path

Django URL not working as expected

I have a URL that does not work, for some reason. I get a 404, "'new' could not be found". Here is my urls.py:
url(r'^assets/new', 'watershed.views.new_asset', name='new_asset'),
There is a lot more in my urls.py but this is the ONLY one that contains the word, "assets" in it. If I change this url to anything/new, it works. If i misspell assets (assettss/new), it works. If I take out the /new and just use "assets", it also works fine. In my views folder I have an __ init __.py which contains the following:
from groups import *
from members import *
from leave_group import *
from payments import *
from assets import *
I also have an assets.py, which contains the following:
from django.contrib.auth.decorators import login_required
from watershed.models import Member, Org, OrgToMember, Asset
from django.shortcuts import render, redirect
from django.contrib.auth.models import User
def new_asset(request):
return render(request, 'asset_add.html')
I have no idea what Django does not like about assets/new.
UPDATE: Here is my full urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
url(r'^', include('outside.urls')),
url(r'^blog', include('blog.urls')),
url(r'^admin', include(admin.site.urls)),
url(r'^logout', 'watershed.views.logout', name='logout'),
url(r'^register/create', 'watershed.views.create', name='create'),
url(r'^register', 'watershed.views.register', name='register'),
url(r'^translog/(\d+)', 'watershed.views.translog', name='translog'),
url(r'^settings', 'watershed.views.settings', name='settings'),
# Group URIs
url(r'^groups/(\d+)/leave', 'watershed.views.leave_group', name='leave_group'),
url(r'^groups/(\d+)/dissolve', 'watershed.views.dissolve_group', name='dissolve_group'),
url(r'^groups/new', 'watershed.views.add_group_form', name='add_group_form'),
url(r'^groups/(\d+)', 'watershed.views.dashboard', name='dashboard'),
url(r'^groups/add', 'watershed.views.add_group', name='add_group'),
url(r'^groups', 'watershed.views.groups', name='groups'),
# Member URIs
url(r'^members/(\d+)', 'watershed.views.profile', name='profile'),
url(r'^member/login', 'watershed.views.login', name='login'),
# Payments URIs
url(r'^payments', 'watershed.views.payments', name='payments'),
# Asset URIs
url(r'^assets/new', 'watershed.views.new_asset', name='new_asset'),
You new_assets function containts in assets.py file, buy you import this function from views.py file. Use this:
url(r'^assets/new', 'path.to.assets.new_asset', name='new_asset'),
I figured it out. The problem is that my static url in my settings.py is - wait for it:
STATIC_URL = '/assets/'
So, clearly, one of those must change.
