Question

您在Django Admin中执行的所有更改都记录在表django_admin_table中，您还可以在“最近操作”中查看最近的更改。

但是当您编写自己的“管理操作”并通过它们进行更改时，默认情况下不会记录任何内容。

示例：

def make_checked(modeladmin, request, queryset):
    queryset.update(checked = 1)
make_checked.short_description = 'Mark selected products as checked'

我现在的问题是，是否可以记录自定义管理操作，如果可以，如何记录？

Answer 1

查看管理员的LogEntry模型，更重要的是LogEntryManager。模型管理器提供了一个log_action方法，可以很容易地添加自己的日志条目（这是未经测试但应该给你的想法）：

from django.contrib.admin.models import LogEntry, CHANGE
from django.contrib.contenttypes.models import ContentType

def make_checked(modeladmin, request, queryset):
    queryset.update(checked = 1)

    ct = ContentType.objects.get_for_model(queryset.model)
    for obj in queryset:
        LogEntry.objects.log_action(
            user_id=request.user.id, 
            content_type_id=ct.pk,
            object_id=obj.pk,
            object_repr=obj.description,
            action_flag=CHANGE,
            change_message="You have ...") 
make_checked.short_description = 'Mark selected products as checked'

您可以看到logging being used in the normal django admin的一些示例。如果您只想为整个查询集添加一个LogEntry，则可以手动执行（因为上面的log_entry需要一组专门用于记录单个对象的参数）：

l = LogEntry(user_id=request.user.id, actions_flag=CHANGE, change_message="...")
l.save()

谢谢！经过一些细微的改变后，工作得很完美：

def make_checked(modeladmin, request, queryset):
    queryset.update(checked = 1)

    ct = ContentType.objects.get_for_model(queryset.model) # for_model --> get_for_model
    for obj in queryset:
        LogEntry.objects.log_action( # log_entry --> log_action
            user_id = request.user.id,
            content_type_id = ct.pk,
            object_id = obj.pk,
            object_repr = obj.title,
            action_flag = CHANGE, # actions_flag --> action_flag
            change_message = 'Changed checked.')
make_checked.short_description = 'Mark selected products as checked'

实际上，现在有比接受的答案更简单的方法，前提是您有ModelAdmin可用，在自定义操作的情况下也可以这样做。

ModelAdmin类的文档尚不完善，但实际上它是provides these methods的快捷方式：

def log_addition(self, request, object, message):
    """
    Log that an object has been successfully added.

    The default implementation creates an admin LogEntry object.
    """

def log_change(self, request, object, message):
    """
    Log that an object has been successfully changed.

    The default implementation creates an admin LogEntry object.
    """

def log_deletion(self, request, object, object_repr):
    """
    Log that an object will be deleted. Note that this method must be
    called before the deletion.

    The default implementation creates an admin LogEntry object.
    """

这些很容易使用。继续问题中的示例：

def make_checked(modeladmin, request, queryset):
    queryset.update(checked = 1)
    for obj in queryset:
        modeladmin.log_change(request, obj, 'Marked checked: ' + str(obj))
make_checked.short_description = 'Mark selected products as checked'
