It's highly unlikely that will you execute unnecessary queries from view code because usually you'll have a context like {"pizzas": page_obj.object_list}. You'll almost never execute something like:
for pizza in pizzas:
print(pizza.topping.name)
But you'll certainly do the following in templates:
{% for pizza in pizzas %}
<p>{{ pizza.topping.name }}</p>
{% endfor %}
I also don't understand why you want to avoid 3rd party packages, especially if it helps you write better code.
- Nextgrid 5y agoMy argument was that the third-party package is what's key here. Merely converting your querysets to a list in code before handing it off to the template won't fully protect you against extra queries. I'm not necessarily trying to avoid third-party packages, in fact I've installed the package you suggested in one of my projects and will be trying it out.
