Reverse for 'details' with arguments '('',)' not found. 2 pattern(s) tried: - django

Question

I can't seem to spot the error in my code and I have tried everything. It is probably something simple that is escaping my eye. Please help! Any input is appreciated. New Django learner here.

Answer 1

The name of the variable in the for loop is actually objects, for some reason. So, just like you use objects.body to display the body, you need objects.id in the URL:
<h1><a href="{% url 'details' objects.id %}"</a>{{ objects.Title }}</h1>
