Refreshing old question but it was something that I've spent some time on as a programming noobie. It kinds of expands Yuji Tomita's answer.

How to sort dictionary that looks like this:

{model_A_object: {key: value, ...},...}

by model_A_object.field.

I fill it with for loop, and use it to store some aggregation, etc., data for queryset that I pass to template.

I've managed to do this (with Shubuntu from #Django help) by:

    result = sorted(dictionary.iteritems(), key= lambda (k, v) :  (k.field, v))

Then in the template:

    {% for model_A_object, data in result %}
        {% for key, value in data.items %}
            ...
        {% endfor %}
    {% endfor %}

Clean and easy, yet not that simple to figure out for beginner. Notice, that first for loop has result not result.items as it's not dictionary anymore, but list of tuples.

Hope it helps someone.
