Reverse for 'create_order' with no arguments not found. 1 pattern(s) tried: ['create_order/(?P<pk>[^/]+)/$'] - django

Question

I'm getting this error when I use
path('create_order/<str:pk>/', views.createOrder, name="create_order"),
but there is no such error when path is..
path('create_order', views.createOrder, name="create_order"),
urls.py
from django.urls import path
from . import views
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"),
]
views.py
def createOrder(request, pk):
OrderFormSet = inlineformset_factory(Customer, Order , fields=('product','status'), extra=9)
customer = Customer.objects.get(id=pk)
formset = OrderFormSet(queryset=Order.objects.none(), instance=customer)
#form = OrderForm(initial={'customer':customer})
if request.method == 'POST':
#print('printing post', request.POST)
formset = OrderFormSet(request.POST, instance=customer)
if formset.is_valid():
formset.save()
return redirect('/')
context = {'formset': formset}
#return redirect('accounts/order_form.html', context)
return render(request, 'accounts/order_form.html', context)
i also have tried redirect, that's not working the problem is with urls.py.

I have added the templates , and thanks to all but I think the only problem is with urls.py , because if I use
path('create_order/<str:pk>/', views.createOrder, name="create_order"),
instead of
path('create_order', views.createOrder, name="create_order"),
then I get error, otherwise there is no such error for the above path.

Answer 1

I finally got the error.
So, error was here
the href which we have used id {% url 'create_order' customer.id %}
and this is in customer.html ,so the customer.id will get value provided by the views.customer
but if you see in your view.customer,
context = {'customers':customers,'orders': orders,'orders_count': orders_count}
because we followed a tutorial video, that guy did some changes which we didn't because it isn't shown in the video.
the changes he did was that
he changed 'customers' to 'customer' and now context of customer.html is good
because now it knows what the hell is customer.id

Answer 2

i know where the problem is
in the dashboard.html you should delete the line includes {% url 'create_order' %}

Answer 3

I don't know what is the problem but just replaced the file urls.py from GitHub with the same context and it's not showing that error.
urls.py
from django.urls import path
from . import views
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"),
]
views.py
from django.forms import inlineformset_factory
def createOrder(request, pk):
OrderFormSet = inlineformset_factory(Customer, Order, fields=('product', 'status'), extra=10 )
customer = Customer.objects.get(id=pk)
formset = OrderFormSet(queryset=Order.objects.none(),instance=customer)
#form = OrderForm(initial={'customer':customer})
if request.method == 'POST':
#print('Printing POST:', request.POST)
#form = OrderForm(request.POST)
formset = OrderFormSet(request.POST, instance=customer)
if formset.is_valid():
formset.save()
return redirect('/')
context = {'form':formset}
return render(request, 'accounts/order_form.html', context)
order_form.html
{% extends 'accounts/main.html' %}
{% load static %}
{% block content %}
<div class="row">
<div class="col-md-6">
<div class="card card-body">
<form action="" method="POST">
{% csrf_token %}
{{ form.management_form }}
{% for field in form %}
{{field}}
<hr>
{% endfor %}
<input type="submit" name="Submit">
</form>
</div>
</div>
</div>
{% endblock %}
Again I don't know why it was showing this error and where was the problem but just relapced it with the same code from GitHub and it worked.if someone know how it worked, that will be really helpful in near future.

Answer 4

in dashboard you should remove the line with create order
cause there is use of create_order url without id so there's an error
