Can't find info on step_set

I'm having trouble with this challenge.

<html>
    <head>
        <title>Ice Cream</title>
    </head>
    <body>
        <div>We have {{ flavors.step_set.all|length }} flavors today.</div>
        <ul>            
        </ul>
    </body>
</html>

I searched in both the django docs and stackoverflow and nothing came up for step_set.

Django is powerful. The variable flavors is a queryset and the length of it is the count. So you can use:

{{ flavors|length }}

Oops. Fixed my answer. The iPhone isn't the best platform for challenges and forum posts.
