I feel embarassed to ask this question as I have solved this type of problem many times, but on this occasion I have failed. I was unable to determine the cause of this and despite copying the code from this repo, this error still persists. All url.py files and views.py are identical. I've been struggling for two days now and just cannot see the error. I'd be grateful for some assistance. Apologies but I really can't figure out how this issue tracker works and to me seems rather antiquated. I've wasted a lot of time trying to format this without any luck. Nothing works as expected. Anyway:-

Page not found (404) No Product matches the given query.

Request Method: GET Request URL : http://localhost:8000/basket` Raised By : store.views.product_detail Using the URLconf defined in core.urls Django tried these URL patterns, in this order:core.urls Django tried these URL patterns, in this order:

1 - basket/
2 - [name='product_all']
3 - [name='product_detail']

The current path, basket, matched the last one.

This view is supposed to be raising the problem but I can't see why it would be...

def product_detail(request, slug): product = get_object_or_404(Product, slug=slug, in_stock=True) return render(request, 'store/products/single.html', {'product': product})

from django.urls import path

from . import views

app_name = 'store'

urlpatterns = [ path('', views.product_all, name='product_all'), path('slug:slug', views.product_detail, name='product_detail'), path('shop/slug:category_slug/', views.category_list, name='category_list'), ] `

1 - basket/
2 - [name='product_all']
3 - [name='product_detail']

The current path, basket, matched the last one.

This view is supposed to be raising the problem but I can't see why it would be...

`from django.shortcuts import get_object_or_404, render

from .models import Category, Product

def product_all(request): products = Product.products.all() return render(request, 'store/home.html', {'products': products})

def category_list(request, category_slug=None): category = get_object_or_404(Category, slug=category_slug) products = Product.objects.filter(category=category) return render(request, 'store/products/category.html', {'category': category, 'products': products})

def product_detail(request, slug): product = get_object_or_404(Product, slug=slug, in_stock=True) return render(request, 'store/products/single.html', {'product': product})'

My store/urls.py:

`from django.urls import path

urlpatterns = [ path('', views.product_all, name='product_all'), path('slug:slug', views.product_detail, name='product_detail'), path('shop/slug:category_slug/', views.category_list, name='category_list'), ]`

My core/urls.py:

`from django.conf import settings from django.conf.urls.static import static from django.contrib import admin from django.urls import include, path

urlpatterns = [ path('basket/', include('basket.urls', namespace='basket')), path('', include('store.urls', namespace='store')), path('admin/', admin.site.urls), ]

if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)`

i was following your tutorial i tried to download to the 3rd part code but it raise this error while running btw thanks your knowledge about django is awesome

Issue: URL Path for activate containing an extra ")" due to which redirect not working for dashboard.

Fix: Removed ")" from URL path for account_activate

Hello sir, I am learning from your YouTube video and also referring your repositories, I found one mistake their that you did not changed in your repositories code but you teach that part in video so I add that code in Part-03 User Payment and Order Management/Final/account/urls.py /

So please make sure I'm added the right code and please add it for other learners. You are great Teacher please keep it up Thank you

The code in Part-01 Django Models Views and Testing/Part-1 Initial/store/admin.py produces the following error when attempting to create a superuser:

<class 'store.admin.ProductAdmin'>: (admin.E116) The value of 'list_filter[1]' refers to 'is_active', which does not refer to a Field.

I noticed that on part3/final/account/forms.py on line 35 the validation was not working. it seems to be working because of the django default validation but clean_username() function is not called upon validation on view. The fix should be:

clean_username(self): ↓ clean_user_name(self):

in store>view.py line 13

category__in=Category.objects.get(name=category_slug).get_descendants(include_self=True)

should most likely be

category__in=Category.objects.get(name=category).get_descendants(include_self=True)

if the slug and the category name does not match, it throws and exception in the original code. The category name is already retrieved in line 13.

The problem is with this line:

path("activate/slug:uidb64/slug:token)/", views.account_activate, name="activate")

The problem is not obvious with console email emulator, if you copy and use the link as is. But the url ending in characters which are not url-safe (specifically ')/' is manifest when sending an actual email - the url in the email text will be displayed in full, but the browser will cut the unsafe characters from the link, and thus the link will always be broken

This is the block we have here in account/views.py:

    try:
        uid = force_text(urlsafe_base64_decode(uidb64))
        user = Customer.objects.get(pk=uid)
    except (TypeError, ValueError, OverflowError, user.DoesNotExist):
  

same block is present in pre-refactorin lectures, starting with Part 04, and up to including Part 10.

obviously, 'user', being a regular variable, doesn't have the DoesNotExist on it. If we replace the lower-case 'user' with, say, Customer (after we've created the class), the error goes away. Python being so dyamic and lenient is a double-edged sword )

I don't know, exactly, why the site keeps working, but once I've enabled debug logging server-side, there came in a flood of messages pointing to the same problem on lines 46 and 125:

           <li {% if category.slug == c.slug %}class="selected" {% endif %}>
              <a class="dropdown-item" href="{{ c.get_absolute_url }}">{{ c.name|title }}</a>

, where 'category' variable does not exist. The code above is taken from Chapter 10.
