Namespacing URL names with multiple parameters in Django 2.0

Question

How do I properly reference the edit_product.html line to the Edit_Product in urls.py with 2 parameters?

I tried looking for examples but I couldn't find any.

This is the error I received:

Reverse for 'Edit_Product' with arguments '('eiffel',)' not found. 1 pattern(s) tried: ['shop/edit_product/(?P[-a-zA-Z0-9_]+)/(?P[-a-zA-Z0-9_]+)/$']

urls.py

from django.urls import path
from . import views

app_name='shop'

urlpatterns = [

    path('create_product/', views.CreateProduct, name='Create_Product'),
    path('edit_product/<slug:c_slug>/<slug:product_slug>/', views.EditProduct, name='Edit_Product'),
    path('', views.allProdCat, name='allProdCat'),
    path('<slug:c_slug>/', views.allProdCat, name='products_by_category'),
    path('<slug:c_slug>/<slug:product_slug>/', views.ProdCatDetail, name='ProdCatDetail'),
]

edit_product.html

<td><a href="{% url 'shop:Edit_Product' category.slug | product.slug %}">{{ product.name }}</a></td>

Don't you need two parameters here? Why do you write | in your {% url ... %}. — willeM_ Van Onsem

path('edit_product/<slug:c_slug>/<slug:product_slug>/', views.EditProduct, name='Edit_Product') and path('<slug:c_slug>/<slug:product_slug>/edit_product', views.EditProduct, name='Edit_Product'), would it still work the same if I type the following in the html: <a href="{% url 'shop:Edit_Product' category.slug product.slug %}"> — moonfairy

You don't need | just separate those with space

<a href="{% url 'shop:Edit_Product' category.slug product.slug %}">
