URLconf for foreign key in a model

Not sure how to title this but I was trying to look up how to put a foreign key value into the URL address.

Here is some example code of what I am trying to do:

#models.py
class Client(models.Model):
name = models.CharField(max_length = 13)

class Product(models.Model):
client = models.ForeignKey(Client, on_delete=models.CASCADE)
name = models.CharField(max_length = 80)
description = models.TextField(blank=True, null=True)

# views.py
class ClientView(generic.DetailView):
model = Client
template_name = 'app/client.html'

class ProductView(generic.DetailView):
model = Product
template_name = 'app/product.html'

#url.py
urlpatterns = [
url(r'^profile/(?P<pk>[0-9]+)/$', views.ClientView.as_view(), name='client'),
## This I am trying to preserve the foreign key and use it here for client
url(r'^profile/(?P<client__pk>[0-9]+)/(?P<pk>[0-9]+)/$', views.ProductView.as_view(), name='product'),
]

Basically I am trying to add the primary key from client into the URL for the product page. Is there a good way to do this?

I made my large flask project open source! CryptoCurrency based community with wallets.

This has been a nonstop project during covid. It was on gitea but moved it to github. Its made with Python flask/ flasksqlalchemy / postgres. I decided to work on the project with my wife after she got a reddit gold and realized it was worth nothing and complained it should be a bitcoin or crypto something. Then we found out it probably benefits tencent (China) the most. So work began to bring the coin back to the people.

Problem creating a basic hello world app

I'm a complete beginner with Django and I'm trying to create a basic hello world app but I have been getting this error:

Request Method:GET

Request URL:http://127.0.0.1:8000/playground/hello/

Using the URLconf defined in Django_project.urls, Django tried these URL patterns, in this order:

admin/

The current path, playground/hello/, didn’t match any of these.

&#x200B;

I created an app with the _python manage.py startapp_ command, called playground.

&#x200B;

Code in playground.views.py

&#x200B;

from django.shortcuts import render

from django.http import HttpResponse

def say_hello(request):

return HttpResponse('Hello World')

&#x200B;

Code in playground.urls.py

from django.urls import path

from .views import views

&#x200B;

#url configuration

urlpatterns = [

path('hello/', views.say_hello)

\]

&#x200B;

and of course in django.urls.py

i added the include function to urlpatterns

&#x200B;

from django.contrib import admin

from django.urls import path, include

&#x200B;

&#x200B;

urlpatterns = [

path('admin/', admin.site.urls),

path('playground/', include('playground.urls'))

\]

So where exactly did i go wrong?
