    queryset.update(status="p")

class ArticleAdmin(admin.ModelAdmin):
    list_display = ["title", "status"]
    ordering = ["title"]
    actions = [make_published]
\#或者
    @admin.action(description="Mark selected stories as published")
    def make_published(self, request, queryset):
        queryset.update(status="p")
        self.message_user(
            request,
            ngettext(
                "%d story was successfully marked as published.",
                "%d stories were successfully marked as published.",
                updated,
            )
