I have the following Models: Restaurant with a Foreignkey for Cardapio, Cardapio with a Manytomany for Product, Product with a Manytomany for Diapromocao, and I need in the template, display some information such as the restaurant, the product, the normal price of the product and the promotional price of the product.

Answer 1

I don’t think it’s a good idea to format the list of products and prices in the model, you can do this directly in the template.

In the template would look something like this:

{% for produto in cardapio.produtos.all %}
    {{ produto }} {{ produto.preco_promocao }}
{% endfor %}
