django select_related in template

Question

Sometimes it makes sense to use select_related in a django template. For example, say I have a class extending DetailView

class DemoCarView(DetailView):
             


        

Answer 1

How about a simple method on the Car model?

class Car(models.Model):
    ...
    def parts_with_manufacturers(self):
        return self.part_set.select_related('manufacturer')

and then

{% for part in car.parts_with_manufacturers %}
    
{{ part.name }} - {{ part.manufacturer.name }} 
{% endfor %}
