Hi,
The reason you are getting this is that you are adding an argument to the
productsgrouping url - which doesn't take any arguments.
In your code you have:
<a href="{% url 'productsgrouping' item.id%}"></a>
(Which by the way isn't correct either, I think you mean: <a href="{% url
'productsgrouping' item.id%}">{{ item }} - {{item.id}} </a>)
If you look at the url for the producsgrouping view, you have:
path('', views.productsgrouping_view, name='productsgrouping'),
Which doesn't take any arguments, when you then add an argument django
can't find the right URL.
You may mean:
<a href="{% url 'update_productsgrouping' item.id%}">{{ item }} - {{item.id}}
</a>
?
Regards,
Andréas
