The Full Menu

Part of the Django Basics section of Coddy's Django journey. Lesson 21 of 23.

The café's full menu is in MENU in menu/views.py: a dictionary of sections, each a list of items. To loop over a dictionary's keys and values together, call its items method. A template calls a method without parentheses, and a loop can unpack two values, like Python's for key, value in d.items(). A week of daily specials:

{% for day, specials in week.items %}
    <h3>{{ day }}</h3>
    <p>{{ specials|join:", " }}</p>
{% endfor %}

Each value is a list, so it can be looped over in turn: a {% for %} inside a {% for %}, each closed by its own {% endfor %}.

Challenge

Medium

menu/menu.html is started for you. Add the menu page at /menu/:

a view that renders it with MENU, and a route named menu;
one <section class="menu-section"> per section, its name in an <h2>;
one <li class="menu-item"> per item: its name, then <span class="price">$4.00</span>.

Press Run: the preview opens /menu/.
