Question

I want to create the products through the customer's profile, so that the customer's name is attached to the form when creating the product that is related to it. But when I try to enter the user profiles from the dashboard it throws this error
urls.py
urlpatterns = [
path('', views.home, name="home"),
path('products/', views.products, name="products"),
path('customer/<str:pk_test>/', views.customer, name="customer"),
path('create_order/<str:pk>', views.createOrder, name='create_order'),
path('update_order/<str:pk>', views.updateOrder, name='update_order'),
path('delete_order/<str:pk>', views.deleteOrder, name='delete_order'),
path('create_customer/', views.createCustomer, name='create_customer'),
]
views.py
Here I focus on the "create Order" function passing the customer's primary key and using "initial" to append the customer's name to the form
def home(request):
orders_value = Order.objects.all()
customer_value = Customer.objects.all()
total_orders_value = orders_value.count()
total_customers_value = customer_value.count()
pending_value = orders_value.filter(status='Pending').count()
delivered_value = orders_value.filter(status='Delivered').count()
context = {'orders_key': orders_value, 'customer_key': customer_value,
'total_orders_key':total_orders_value, 'pending_key': pending_value,
'delivered_key': delivered_value}
return render (request, 'accounts/dashboard.html', context)
def products(request):
products_value = Product.objects.all()
return render (request, 'accounts/products.html', {'products_key': products_value})
def customer(request, pk_test):
customer_value = Customer.objects.get(id=pk_test)
orders_value = customer_value.order_set.all()
orders_value_count = orders_value.count()
context = {'customer_key':customer_value, 'orders_key': orders_value, 'orders_key_count': orders_value_count}
return render (request, 'accounts/customer.html', context)
def createOrder(request, pk):
customer = Customer.objects.get(id=pk)
form_value = OrderForm(initial={'customer':customer})
if request.method == 'POST':
form_value = OrderForm(request.POST)
if form_value.is_valid:
form_value.save()
return redirect('/')
context = {'form_key':form_value}
return render(request, 'accounts/order_form.html', context)
def updateOrder(request, pk):
order = Order.objects.get(id=pk)
form_value = OrderForm(instance=order)
if request.method == 'POST':
form_value = OrderForm(request.POST, instance=order)
if form_value.is_valid:
form_value.save()
return redirect('/')
context = {'form_key':form_value}
return render(request, 'accounts/order_form.html', context)
def deleteOrder(request, pk):
order = Order.objects.get(id=pk)
if request.method == 'POST':
order.delete()
return redirect('/')
context={'item':order}
return render (request, 'accounts/delete.html', context)

This is the error that throws me
NoReverseMatch at /customer/1/
Error during template rendering
Reverse for 'create_order' with arguments '('',)' not found. 1 pattern(s) tried: ['create_order/(?P<pk>[^/]+)$']
Maybe i wrote some wrong in "customer.html" but i dont know where and i cant find the error... I need help, please

Answer 1

inside your template customer.html
change this(why ? because inside your context = {'customer_key':customer_value, 'orders_key': orders_value, 'orders_key_count': orders_value_count} that refers to this template there is no key called 'customer' and you tried to access again his id that is not correct)
<a class="btn btn-outline-info btn-sm btn-block" href="{% url 'create_order' customer.id %}">Place Order</a>
to (if you look your context you have a customer_key that is from your Customer model to get his id you can just use customer_key.pk)
<a class="btn btn-outline-info btn-sm btn-block" href="{% url 'create_order' customer_key.pk %}">Place Order</a>
there is some mistake inside your urls.py(pk is an integer so instead of str(string) you should use int(integer))
urlpatterns = [
path('', views.home, name="home"),
path('products/', views.products, name="products"),
path('customer/<int:pk_test>/', views.customer, name="customer"),
path('create_order/<int:pk>', views.createOrder, name='create_order'),
path('update_order/<int:pk>', views.updateOrder, name='update_order'),
path('delete_order/<int:pk>', views.deleteOrder, name='delete_order'),
path('create_customer/', views.createCustomer, name='create_customer'),
]
