Here is the error message:
django.core.exceptions.ImproperlyConfigured:
The included URLconf '<module 'basicsiteApp' from '/Users/msa/trydjango/basicsite/basicsiteApp/__init__.py'>'
does not appear to have any patterns in it.
If you see valid patterns in the file then the issue is probably
caused by a circular import.
I don't have anything written in init.py because I don't know what I need to write in it so it can work.
Below is what I have in views.py:
from django.shortcuts import render
from .forms import SignUpForm
from django.contrib import messages
def signup(request):
if request.method == 'POST'
form = SignUpForm(request.POST)
if form.is_valid():
form.save()
messages.success(request, 'Account Created')
return render(request, 'signup.html')
else:
form = SignUpForm()
render(request, 'signup.html')
Basicsite/urls.py:
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('', include('basicsiteApp')),
path('admin/', admin.site.urls)
]
basicsiteApp/urls.py:
from django.urls import path
from . import views
app_name = 'basicsiteApp'
urlpatterns = [
path('', views.signup, name='signup')
]
I know it comes late, but if someone (like me) faces the same problem:
In your "Basicsite/urls.py"
path('', include('basicsiteApp')),
it should be
path('', include('basicsiteApp.urls')),
implying django to use the basicsiteApp/urls.py file instead of basicsiteApp/init.py

I need the following in the SIMPLEST DRY manner possible; how do I write this redirect inside contact/views.py?
return redirect('PostList') #another view from another app
PostList is a class-based view from another app called blog. It is the homepage essentially.
for reference..

In your project folder (eg, my_project/my_project) you should have a urls.py with something like this
path("admin/", admin.site.urls),
path("", include("blog.urls")),
path("", include("contact.urls"))
This allows django to look through all url files in the order listed. So long as all your url names and patterns are unique, then your view should be able to simply do
from django.shortcuts import redirect
from django.urls import reverse
return redirect(reverse('home'))
'home' being the name value of the ListView.
(NB: if you have various applevel urls.py files with path(''... django will take the first one it hits)
I have two apps in my Django project:basket and store. In root url files I configured the urls.py like this:
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('store.urls', namespace='store')),
path('basket/', include('basket.urls', namespace='basket')),
store/urls.py:
from django.urls import path
from . import views
app_name = 'store'
urlpatterns = [
path('', views.all_products, name='all_products'),
path('<slug:slug>/', views.product_detail, name='product_detail'),
path('category/<slug:category_slug>/',
views.category_list, name='category_list')
]
basket/urls.py:
from django.urls import path
from . import views
app_name = 'basket'
urlpatterns = [
path('', views.basket_summary, name='basket_summary'),
path('add/', views.basket_add, name='basket_add'),
]
I am getting an error:
Page not found(404)
Request Method:GET
Request URL:http://127.0.0.1:8000/basket/
Raised by:store.views.product_detail
this is my store/views.py:
from django.shortcuts import get_object_or_404, render
from .models import *
def product_detail(request, slug):
product = get_object_or_404(Product, slug=slug, in_stock=True)
context = {
'product': product,
}
return render(request, 'store/products/detail.html', context)
please help me solve this problem i've been stuck on this for a long time.
Try this way if you want to avoid 404 error:
from django.shortcuts import get_object_or_404, render
from .models import *
def product_detail(request, slug):
try:
product = Product.objects.get(slug=slug, in_stock=True)
context = {
'product': product,
}
except Product.DoesNotExist:
raise ValidationError('Product Does not exist ')
return render(request, 'store/products/detail.html', context
)
so the error is Page not found(404) when I am requesting the instance that does not exist. I would like to customize the 404 page, instead of displaying the general error.
Here is my new_wiki/urls
from django.urls import path
from . import views
from .views import IndexView, InstanceView, AddPostView, EditPost
urlpatterns = [
# path('', views.index, name="index")
path('', IndexView.as_view(), name="index"),
path('instance/<int:pk>', InstanceView.as_view(), name="instance"),
path('create_post/', AddPostView.as_view(), name="create_post"),
path('instance/edit/<int:pk>', EditPost.as_view(), name="edit_post")
]
And my InstanceView class
class InstanceView(DetailView):
model = Post
template_name = 'new_wiki/instance.html'
I have tried to use the solution from Django documentation:
def detail(request, post_id):
try:
p = Post.objects.get(pk=post_id)
except Post.DoesNotExist:
raise Http404("Poll does not exist")
return render(request, 'new_wiki/instance.html', {'post': p})
but it is still returning the same 404 page. Thank you
You can just render a page with a 404 status:
def detail(request, post_id):
try:
p = Post.objects.get(pk=post_id)
except Post.DoesNotExist:
return render(request, 'new_wiki/404error.html', status=404)
return render(request, 'new_wiki/instance.html', {'post': p})
If you want to specify a custom 404 page in general, you specify the handler404 [Django-doc] in the urls.py:
from django.urls import path
from . import views
from .views import IndexView, InstanceView, AddPostView, EditPost
urlpatterns = [
# path('', views.index, name="index")
path('', IndexView.as_view(), name="index"),
path('instance/<int:pk>', InstanceView.as_view(), name="instance"),
path('create_post/', AddPostView.as_view(), name="create_post"),
path('instance/edit/<int:pk>', EditPost.as_view(), name="edit_post")
]
handler404 = views.handler404
In the view you can then analyze the exception parameter and return a specific
# app/views.py
from django.http import HttpResponseNotFound
def handler404(request, exception):
data = exception.args
if data:
return HttpResponseNotFound(data[0])
return HttpResponseNotFound('some text')
This then works if you set the DEBUG setting [Django-doc] to False:
# settings.py
DEBUG = False
In that case the handler will be invoked when you raise a Http404.
Please use get_object_or_404 method
from django.shortcuts import get_object_or_404
def detail(request, post_id):
p = get_object_or_404(Post,pk=post_id)
return render(request, 'new_wiki/instance.html', {'post': p})
Please check this is working.
Could someone please help me. I get the following error when loading my project:
raise ImproperlyConfigured(msg.format(name=self.urlconf_name))
django.core.exceptions.ImproperlyConfigured: The included URLconf
'siteV1.urls' does not appear to have any patterns in it. If you see
valid patterns in the file then the issue is probably caused by a
circular import.
This is my urls.py
from django.contrib import admin
from django.urls import path
from django.conf import settings
from django.conf.urls.static import static
from drink.views import HomepageView, CreateDrinkView, CreateNormalDrinkView, CreateMixedDrinkView
from machine.views import SettingsView
from account.views import LoginView

path('', HomepageView.as_view()),
path('create-drink', CreateDrinkView.as_view()),
path('create-drink/save-normal', CreateNormalDrinkView.as_view()),
path('create-drink/save-mixed', CreateMixedDrinkView.as_view()),
path('settings/', SettingsView.as_view()),
path('accounts/login/', LoginView.as_view()),
path('admin/', admin.site.urls),
]
if settings.DEBUG == True:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
else:
pass
#enter code here for media and static handeling during production
The problem seems to be related to the import of the LoginView. If I delete this import and path the program runs without any errors. My accounts.views contains the following code:
from django.contrib.auth import authenticate, login
from django.shortcuts import render, redirect
from django.views.generic import TemplateView
# Create your views here.
class LoginView(TemplateView):
template_name = 'login.html'
def get(self, request):
return render(request, self.template_name, {})
def post(self, request):
username = request.POST['username']
password = request.POST['password']
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
# Redirect to a success page.
return redirect('')
else:
# Return an 'invalid login' error message.
return render(request, self.template_name {'error': 'Gebruikersnaam of wachtwoord onjuist!'})
The account.models is empty at the moment. I tried running pycycle to check for circular imports. Pycycle returned that there were no circular imports found. Your help is much appreciated!
Solved this by deleting the app and recreating it. Still don't know what the problem is but it works for now.
I'm new to Django, and trying to create my first project. I tried to resolve the above mentioned error, spent hours banging my head against the wall, but was unable to correct it.. Given below are the relevant files. I guess it must be a small thing that I am missing, but unable to pin point it.
Views.py:
from django.shortcuts import render
from django.http import HttpResponse, JsonResponse

def home(request):
if request.GET.get('type') == 'formdata':
options = {'fruits': [], 'vendors': [], 'release_version': []}
try:
options['fruits'] = ['Mango', 'apple', 'banana']
options['vendors'] = ['Amazon', 'flipkart', 'myntra']
options['release_version'] = ['2015','2016','2017','2018']
today = datetime.today()
options['end_date'] = today.strftime('%Y-%m-%d')
last_week_date = today - timedelta(days=7)
options['start_date'] = last_week_date.strftime('%Y-%m-%d')
return JsonResponse({'options': options})

return JsonResponse({'message': 'An error occured while getting form data'})
return render(request, 'index.html')

Urls.py
from django.contrib import admin
from django.urls import path
from . import views
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.home, name='home')
]
The index.html is the template I want the urls.py to point to, and is in the templates/project_name folder in my project. I have also set the TEMPLATES_DIR in the settings.py. I wonder where I am going wrong. Any help is appreciated.
