@admin.action(description="Mark selected stories as published")
def make_published(modeladmin, request, queryset):
    queryset.update(status="p")


class ArticleAdmin(admin.ModelAdmin):
    list_display = ["title", "status"]
    ordering = ["title"]
    actions = [make_published]


admin.site.register(Article, ArticleAdmin)
