What should I do?? I need a specific code directly to write on!
As the error said, inside your web3auth/urls.py you need to set app_name attribute. For example:
# web3auth/urls.py
from django.urls import path
from . import views
app_name = 'web3auth'
urlpatterns = [
...
]
You can checkout the documentation as well.

ModuleNotFoundError: No module named 'router'
please help me
ignore that this text is to avoid "it's look like post is mostly code,please add something "
urlpatterns = [
path('',include('router.urls')),

should be:
urlpatterns = router.urls
The include expression goes looking for a router module.
Use
path('', include(router.urls))
without quotes
While I'm trying to add a urls configuration in my urls.py file, I'm getting an error like ModuleNotFoundError: No module named 'employee.urls' and OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: ''
urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('employee/',include("employee.urls"))
]
directory and file path
It's a convention to name all your url config files urls.py not url_<appname> unless you have a very special use-case.
But in either case, you must import the url file after your filename. So if you want to keep the filename as is, try this:
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('employee/',include("employee.urls_employee"))
I start up an app named "article" but and configure an import like this: from article import * in the setting configure file, then when I run python manage.py runserver the error ocuur like this AttributeError: module 'article.admin' has no attribute 'site', when I comments from article import * with #, it will work on well, I do not know how from article import * raise the problem.
from article import *
atterns = [
path('admin/', admin.site.urls),
url(r'^article/',include('article.urls',namespace='article')),
]
The output:
File "<frozen importlib._bootstrap>", line 205, in _call_with_frames_removed
File "D:\pythonTestfolder\xuegod\blogtest\blogtest\urls.py", line 25, in <module>
path('admin/', admin.site.urls),
AttributeError: module 'article.admin' has no attribute 'site'
You don't need to import from your article app here
especially all of its contents with *
include method will work with a string of app_name and it's urls.py file , as you have wright corectly
and after that if it is a newer version of django project you are using , try not to use
url method because it is going to be deprecated use re_path() instead , if you want to check for regex urls:
from django.urls import path, re_path, include
urlpatterns = [
path('admin/', admin.site.urls),
re_path(r'^article/',include('article.urls',namespace='article')),
]
I'm trying to get familiar with django-RESTframeworks, therefore I started the official tutorial, to create a Test-API.
https://www.django-rest-framework.org/tutorial/quickstart/#quickstart
When finally starting the API on my Windows via [CMD] "pyhon manage.py runserver", I get an error code on the command line, which you will see below.
I also want to add, that unfortunately, there is some ambiguity in the descriptions in the tutorial, at least from the viewpoint of a beginner, i.e. it's not always certain whether the corresponding code in the tutorial
needs to be added in a module or replace all or part of the code in the modules.
Therefore, I tried implementing the directions of the tutorial in various ways, always with the same end result.
I'm running the code in a virtual env, where i've installed Django 1.11., so there shouldn't be an issue with different Django versions.

Most probably you are using django<2.0 but following tutorials which are written in django>2.0. From django 2.0, include has been moved to django.urls, before it resided in django.conf.urls(changelog reference). So you need to update your urls.py like this:
from django.conf.urls import url, include
from django.contrib import admin
from rest_framework import routers
from tutorial.quickstart import views
router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
You can't use path as well, because it was introduced in django 2 as well.
Or you can move to django>2.0, but in that case you have to remove from django.conf.urls import url and use from django.urls import url.
models.py
from django.conf.urls import include, url
app_name = "Review"

I am providing app_name before my urlpatterns. But it's giving me error while running my code. The errors are given below:

Please help.
The app_name needs to be set in your app's urls.py not the main urls.py.
In review.urls.py add the following,
from django.conf.urls import include, url
from django.contrib import admin
from .views import ( ReviewUpdate, ReviewDelete, )
app_name = 'Review'
urlpatterns = [
url(r'^reviews/(?P<pk>\d+)/edit/$', ReviewUpdate.as_view(), name='review_update'),
url(r'^reviews/(?P<pk>\d+)/delete/$', ReviewDelete.as_view(), name='review_delete'),
]
and remove the app_name from the main urls
EDIT: for the admin issue that the op mentioned in the comments,
in the main urls.py
from django.urls import path
urlpatterns = [
path('admin/', admin.site.urls),
]
You need to define app_name in urls.py and pass urlconf_module in tuple . Here is example
app_name = "example"
from typing import NamedTuple
class NamedURL(NamedTuple):
urlconf_module: None
app_name: None
daily_urls = NamedURL(<your custom urls in list>, "example")
urlpatterns = [
...
re_path(r'^daily/', include(daily_urls, namespace='daily')),
]
