Question

I’d like to use a variable as an key in a dictionary in a Django template. I can’t for the life of me figure out how to do it. If I have a product with a name or ID field, and ratings dictionary with indices of the product IDs, I’d like to be able to say:

{% for product in product_list %}
     <h1>{{ ratings.product.id }}</h1>
{% endfor %}

In python this would be accomplished with a simple

ratings[product.id]

But I can’t make it work in the templates. I’ve tried using with… no dice. Ideas?

Answer 1

You need to prepare your data beforehand, in this case you should pass list of two-tuples to your template:

{% for product, rating in product_list %}
    <h1>{{ product.name }}</h1><p>{{ rating }}</p>
{% endfor %}
