获取对象的历史 [英] Getting the history of an object

问题描述

我使用django admin来添加他们的Model对象，如你所知，django正在跟踪用户操作的跟踪，例如添加了一个项目的用户。对于一个对象，在管理面板外面的自定义视图中，我需要显示加法器的用户名。

如何获取/检索这些数据？ p>

干杯

解决方案

这只是一个粗略的草图，但应该是非常接近您需要的视图：

  from django.contrib.admin.models import LogEntry，ADDITION 
 
 def your_view（request）：
 ... 
＃这是您修改的对象
 my_obj = ... 
 log_entry = LogEntry.objects.filter（
 object_id = my_obj.id，
 action_flag = ADDITION，
 content_type__id__exact = ContentType.objects.get_for_model（MyModel）.id）
 ... 
  

然后在您的模板中：

  {{ log_entry.user.username}} 
  

I use django admin for my users to add their Model objects, as you know django is keeping the track of user actions such as the user who added an item. For an object, At a custom view outside the admin panel, I need to display the user name of the adder.

How can I fetch/retrieve this data ?

Cheers

解决方案

This is just a rough sketch but should be pretty close to what you need for your view:

from django.contrib.admin.models import LogEntry, ADDITION

def your_view(request):
    ...
    # This is your object that was modified
    my_obj = ...
    log_entry = LogEntry.objects.filter(
        object_id=my_obj.id,
        action_flag=ADDITION,
        content_type__id__exact=ContentType.objects.get_for_model(MyModel).id)
    ...

Then in your template:

{{ log_entry.user.username }}
