save_model(request, obj, form, change)

此方法为admin界面用户保存model实例时的行为。request为HttpRequest实例，obj为model实例，form为ModelForm实例，change为bool值，取决于model实例是新增的还是修改的。

重写此方法可以做一些pre-save或者post-save行为。

比如，可以把request.user保存为model实例的属性：

from django.contrib import adminclass ArticleAdmin(admin.ModelAdmin):    def save_model(self, request, obj, form, change):        obj.user = request.user        obj.save()
