CookBook - Template tag Regroup
If you need to group a list of objects by a choice like fied choices = CATEGORY_CHOICES, here is the trick.
A Model.
CATEGORY_CHOICES = ( (1, 'Entrées'), (2, 'Poissons et crustacés'), (3, 'Viandes et volailles'), (4, 'Légumes et accompagnements'), (5, 'Desserts'), (6, 'Boissons'), (8, 'Autres'), ) class Recette(meta.Model): [...] categorie = meta.SmallIntegerField(choices = CATEGORY_CHOICES)
The Rrgroup tag in action, the thing is that you don't want to display the category number bit its corresponding name. (e.g not '1' but 'Entrées').
Temmplate
{% regroup recettes by categorie as grouped %} <ul> {% for group in grouped %} <li>{{ group.list.0.get_categorie_display }} <ul> {% for item in group.list %} <li>{{ item }}</li> {% endfor %} </ul> {% endfor %} </ul>
