Question

我有两个问题因为django-reversion应用程序有点混乱。我有一个页面，用户可以看到列出所有的逆转。每个版本都有可以恢复的按钮。

1问题：如何仅显示某些更改字段。现在它向我展示了所有领域。我使用的是version.field_dict.items。

2问题：如何正确还原到特定版本？

下面你可以看到代码，但是当我尝试单击以恢复链接时，它会在views.py中引发错误。我做错了什么？

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)

错误：
