Your current error is caused by passing TemplateView into your url conf. It should be TemplateView.as_view().
urlpatterns = patterns('',
#...
(r'^accounts/profile/$', TemplateView.as_view(template= 'registration/profile.html')),
#...

I'm trying to add a new page in Django but getting 404 error yet I've added urls and views

I'm a newbie trying to add an a new page but get the following error:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/study
Using the URLconf defined in student_management_system.urls, Django tried these URL patterns, in this order:
I've added a function for the page in Views.py and also added the path in URLS.py.
StudentViews.py ---> in student management app folder:
from django.shortcuts import render, redirect

login(request, user)
user_type = user.user_type
#return HttpResponse("Email: "+request.POST.get('email')+ " Password: "+request.POST.get('password'))

urlpatterns = [
path('', views.loginPage, name="login"),
path('student_view_result/', StudentViews.student_view_result, name="student_view_result"),
path('study/', StudentViews.study, name="study"),

from student_management_system import settings
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('student_management_app.urls')),
]+static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
How could I resolve this error? And why it reported this error?

Why am I getting error 404 in my django project when everything seems correct?

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
)

dblog.verification_status = 'Verified'
print dblog.verification_status
dblog.save()
#.update(dblogdetails.verification_status = 'Verified')
return HttpResponseRedirect(request.GET.get('next'))
NOTE: NOT able to reach to MyView.get() and no db update happening. I assume my code is not able to read my function.

Django NoReverseMatch Error

I'm trying to develop a blog script with Django. But when I want to show post links, I get NoReverseMatch error.

except Yazi.DoesNotExist:

return render_to_response('Penguencik_Yazilar/yazi_list.html', c)
def Detail(request, slug):
post = Yazi.objects.get(slug=slug)
site = Site.objects.get_current()
c= RequestContext(request,{
'posts':post,

return render_to_response('Penguencik_Yazilar/yazi_detail.html',c)
Urls.py in application folder.

Urls.py in project folder

# Uncomment the next two lines to enable the admin:

urlpatterns = patterns('',
url(r'^$', include('Penguencik_Yazilar.urls',namespace='blog')),
url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
url(r'^admin/', include(admin.site.urls)),
)
And template code. What am I doing wrong?
{% load url from future %}
...
Read

Try to change this:
Read
to:
Read
Cause your view expect slug keyword here (?P<slug>[0-9A-Za-z._%+-]+).

Django - Why doesn't reverse work?

I'm trying to make a view redirect to another view so user's can't access it without a condition being met. In this case, a successful password change. I also want to achieve this using HttpResponseRedirect.
Now, I've never used reverse before, but I figured that this is the way to do that. Problem is that I can't get reverse to work. I get the following error:
ViewDoesNotExist at /account/password/

You have to specify name kwargs in you url, in this case :
url(r'^account/password/success/$', 'findadownload.accounts.views.password_success', name = 'password_success')
Then use reverse like this :
return HttpResponseRedirect(reverse('password_success'))
What you pass in reverse is the name kwarg on urlpatterns.
EDIT:
Can i see the rest of your urls.py. I think the problem is not on reverse, because Django can't find view named foo.
