Show field_dict.items() of django-reversion in template

I am tring to use django reversion app in my project. I am little bit comfused. How to show list of changes (field_dict.items()) in template?

models.py:

@reversion.register()
class Function(models.Model):
    ***FIELDS***

views.py:

def function_revisions(request, function_code):
    function = get_object_or_404(Function, pk=function_code)
    versions = Version.objects.get_for_object(Function)
    context = {
        'function': function,
        'versions': versions,
    }
    return render(request, 'project/function_revisions.html', context)

function_revisions.html:

{% for version in versions %}
     <p>Version: {{ forloop.counter }}.</p>
     <p>Revision by {{ version.revision.user }}.</p>
     <p>Date of revision : {{ version.revision.date_created }}.</p>

     {% for field_name, field_value in version.field_dict.items() %} <-- ???
         <p>Field </p>{{ field_name }} had the value {{ field_value }}<p>
     {% endfor %}
{% endfor %}

ERROR:

You're passing the wrong thing into get_for_object - you need to pass the instance, function, not the model, Function.

Drop the parens and the Django template engine will do the calling for you:

{% for field_name, field_value in version.field_dict.items %}

This works for methods that take zero arguments.
