创建Django管理操作以复制记录

您有正确的想法,但是您需要遍历queryset,然后复制每个对象。

def duplicate_event(modeladmin, request, queryset):
    for object in queryset:
        object.id = None
        object.save()
duplicate_event.short_description = "Duplicate selected record"

也许这对你有用。

def duplicate_query_sets(queryset, **kwargs):
    for p in queryset:
        p.pk = None
        for i, v in kwargs.iteritems():
            setattr(p, i, v)

        p.save()
