Django让所有提交按钮返回主页

我有一个应用程序,有一个主页,有几个按钮。每个按钮执行一些查看功能,然后返回主页。单击下面的按钮时,返回主页,但url显示: http://localhost:8080/abc_app/backup_system

还有什么需要我回去的吗 http://localhost:8080/abc_app http://localhost:8080/abc_app/backup_system

提前谢谢。

<form action="{% url 'abc_app:backup_system' %}" method="post">{% csrf_token %}
   <button type="submit" name="index" class="btn btn-primary btn-block float-right"value="index">Refresh</button>
</form>

def backup_system(request):
    status = g_abc_api.backup_system()
    return index(request)
    # I have tried HttpResponseRedirect('/compost') as well.
    # If possible, it would be great to have the 'status' variable returned from the API available in  index(request) so I can display errors.

def index(request):
    '''
    Populate context
    ''
    return render(request, 'abc_app/index.html', context)
