How do I pass a slug to the URL in Django?

At this point I just want to call a page based on my table.html template. I'll work on adding all of my table data later. Presently, when I click on my link to a table on the index.html page I get a "TypeError... table() got an unexpected keyword argument 'd_100_id'.

I've tried removing unnecessary code from the table view and template, and I checked in an incognito Chrome browser in case I'm getting the old page each time.

My views.py page

from django.shortcuts import get_object_or_404, render

from .models import D100Generator

def index(request):
    latest_table_list = D100Generator.objects.order_by('-d_100_id')[:5]
    context = {
        'latest_table_list': latest_table_list
    }
    return render(request, 'generators/index.html', context)

def table(request, table_slug):
    table = get_object_or_404(D100Generator, pk=table_slug)
    return render(request, 'generators/table.html', {'table': table})

My url.py (in case this helps):


from . import views
app_name = "generators"

urlpatterns = [
    path('', views.index, name='index'),
    path('table/<slug:d_100_id>', views.table, name='table'),
]

index.html

<br>
<h2>Recent tables added include:</h2>
{% if latest_table_list %}
    <ul>
    {% for table in latest_table_list %}
        <li><a href="/generators/table/{{ table.table_slug }}">{{ table.table_name }}</a></li>
    {% endfor %}
    </ul>
{% else %}
    <p>No tables are available.</p>
{% endif %}

and table.html <h1>{{ table.table_name }}</h1>

I wanted it to call at least the table.html page and display the table_name.

What I got instead was an error message at the top of the page:

TypeError at /generators/table/your-elf-spent-25-years-learning

table() got an unexpected keyword argument 'd_100_id'

I can post the traceback as well if needed.

Your path should look like this: path('table/<slug:table_slug>', views.table, name='table'),

def table(request, table_slug):
    table = get_object_or_404(D100Generator, pk=table_slug)
    return render(request, 'generators/table.html', {'table': table})

Also, in template, you can use url template tag to reverse the URL rather than hardcoding it:

<li><a href="{% url 'generators:table' table_slug=table.pk %}">{{ table.table_name }}</a></li>
