我有 2 个问题导致对django-reversion应用程序有点困惑。我有页面，用户可以在其中查看所有版本的列表。每个版本都有恢复按钮。

1 问题：如何仅显示某些更改字段。现在它向我显示了所有字段。我使用 version.field_dict.items。

2 问题：如何正确恢复到特定版本？

在下面您可以看到代码，但是当我尝试单击以还原链接时，它会在 views.py 中引发错误。我做错了什么？

模板.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 %}

网址.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'),

视图.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)

错误：

Internal Server Error: /ru/account/dashboard/projects/42442299-97dd-4d92-9ef1-880f9cdd1612/4d3d3422-2618-4d66-96f5-8f0a0b5d9bf3/21/
