如何正確回覆到django-reversion中的特定版本？

Question

我有2個問題引起一點點與django-reversion應用程序comfusion。我有頁面，用戶可以看到列出所有的反轉。每個版本都有按鈕可以恢復。

1問題：如何僅顯示一些更改的字段。現在它向我展示了所有領域。我使用version.field_dict.items。

2問題：如何正確恢復到特定版本？

下面您可以看到代碼，但當我嘗試點擊以恢復鏈接時，它會在views.py中引發錯誤。我做錯了什麼？

template.html

{% for version in versions %} 
     {% for field_name, field_value in version.field_dict.items %} 
      {{ field_name }} 
      {{ field_value }} 
     {% endfor %} 
     <a href="{% url 'project:group_task_revert' project_code=project.code group_task_code=group_task.code group_task_reversion_id=version.revision.id%}">REVERT</a> 
{% endfor %} 

urls.py：

url(r'^(?P<project_code>[0-9a-f-]+)/(?P<group_code>[0-9a-f-]+)/(?P<group_reversion_id>\d+)/$', 
     group_revert, 
     name='group_revert'), 

views.py：

def group_revert(request, project_code, group_code, group_reversion_id): 
    project = get_object_or_404(Project, pk=project_code, status='open') 
    group = get_object_or_404(Group, pk=group_code) 

    versions = Version.objects.get_for_object(group) 
    versions[group_reversion_id].revision.revert() 

    return redirect('project:project_detail', project_code=project.code) 

錯誤：
