I can't found what is wrong with urls.py - python

I can't find where is bug. It's my begining with django. If somebody helping me i will grateful.

Judging by your screenshot of your folder structure, the outer superlista is the project root, and the installed apps are superlista and lists.
If you have correctly defined the INSTALLED_APPS setting, your import should be:
from lists import views

ModuleNotFoundError: No module named 'members.urls'

I tried to start a app so that I can create a Login for my blog but I came by this error.
So I thought to post a question in stack over flow. I hope yu can take some time to answer my question.

ModuleNotFoundError: No module named 'members.urls'
Here is the url for members
from django.urls import path

Here is the urls for ablog
from django.contrib import admin

urlpatterns = [
path('admin/', admin.site.urls),
path('',include('myblog.urls')),
path('members/', include('django.contrib.auth.urls')),

Here is my views.py
from django.shortcuts import render

from django.urls import reverse_lazy
class UserRegisterView(generic.CreateView):
form_class = UserCreationForm
template_name = 'registration/register.html'
success_url = reverse_lazy('login')
How do I solve this error.

At first Correct your urlpatterns:(you forgot , )
path('register/', UserRegisterView.as_view(),name='register'),
also make sure for migrations

I got the same problem and I was missing the urls.py file in my app.
Add urls.py file in members app.

How to setup Django every time you use it? (i.e. using **source bin/activate** and ** python manage.py runserver**)

I am a beginner with Django, and I am very confused as to how to consistently setup Django everytime you are opening a new terminal. Whenever I do so, I have to always restart and do the following:
Change directory (cd) to my trydjango directory where I start the virtual environment (source bin/activate)
After the terminal has the automatic (trydjango) at the furthest left of (trydjango) lyons-MacBook-Air:trydjango lyons$ I know that I have the virtual environment enabled.
Then, I go to the src directory through the terminal where I enter python manage.py runserver
I am running into consistent errors (e.g. AttributeError) whenever I enter the runserver step (step 3). Am I doing something wrong?
The following is the full Traceback of the error

It looks like you are passing the string representation of the name to include() rather than the actual articles.urls variable. Instead, it should look something like this:
from articles import urls as article_urls
...
urlpatterns =[
url(r'article/',include(article_urls, namespace='article'))
]

the problem is explained in this way:
skcms/urls.py
from django.urls import include, path
urlpatterns =[
path('article/',include('articles.urls')),
]
articles/urls.py
from django.urls import path
from . import views
urlpatterns =[
path('', views.articles, name='articles'),

i've read a few tutorials and the code is being referred from https://www.tutorialspoint.com/django/django_url_mapping.htm but not sure why i am getting an error.

Just replace the url with path:
# main urls.py
urlpatterns = [
path('admin/', admin.site.urls),
path('myapp/', include('myapp.url'))
]
# app urls.py
from django.urls import path
from .view import hello
urlpatterns = [
path('hello/', hello, name='hello'),
]
As you can see in documetation, path has been introduced(from Django>=2.0), so you don't have to use url here. The tutorial you are following is for older versions, so it is using url with regex to generate URLs.

AttributeError: module 'django.contrib.auth.views' has no attribute 'LoginView'

I am using an older version of django.After i run my code i get this error -"AttributeError: module 'django.contrib.auth.views' has no attribute 'LoginView'".I should get error if I use login instead of LoginView. Even after using login I get the same attribute error.
this is my urls.py-
from django.conf.urls import url
from django.contrib.auth import views as auth_views
from . import views
app_name = 'accounts'
urlpatterns = [
url(r"login/$",auth_views.LoginView.as_view(template_name="accounts/login.html"),name='login'),
url(r"logout/$", auth_views.LogoutView.as_view(), name="logout"),
url(r"signup/$", views.SignUp.as_view(), name="signup"),
]
this is my app's urls.py-
from django.conf.urls import url,include
from django.contrib import admin
from .import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^$',views.HomePage.as_view(),name='home'),
url(r'^accounts/',include('accounts.urls',namespace='accounts')),
url(r'^accounts',include('django.contrib.auth.urls')),
url(r'^test/$',views.TestPage.as_view(),name='test'),
url(r'^thanks/$',views.ThanksPage.as_view(),name='thanks')
]
and views.py-
from django.shortcuts import render
from django.contrib.auth import login, logout
from django.core.urlresolvers import reverse_lazy
from django.views.generic import CreateView
from . import forms
class SignUp(CreateView):
form_class = forms.UserCreateForm
success_url = reverse_lazy("login")
template_name = "accounts/signup.html"
I got this result after making migrations.My app's name is accounts:-

AttributeError: module 'django.contrib.auth.views' has no attribute 'LoginView'

LoginView was added in Django 1.11. If the import fails, you must be using an older version of Django.
Django 1.11 LTS is the oldest supported version of Django, so you really should upgrade, ideally to the latest version 2.2.

It is always a good idea to say which version you are using. Anyway, the class "LoginView" was implemented in Django 1.11 (https://docs.djangoproject.com/en/1.11/topics/auth/default/#django.contrib.auth.views.LoginView)
If your version is compatible with that, try to change the url part to something like:
path('accounts/login/',auth_views.LoginView.as_view(template_name='myapp/login.html'))
Hope it helps
