# admin.site.unregister(Group)
admin.site.register(models.Asset,AssetAdmin)
admin.site.register(models.Server)
admin.site.register(models.NetworkDevice)
admin.site.register(models.IDC)
admin.site.register(models.BusinessUnit)
admin.site.register(models.Contract)
admin.site.register(models.CPU)
admin.site.register(models.Disk)
admin.site.register(models.NIC,NicAdmin)

admin.site.register(models.Tag)
admin.site.register(models.Software)
admin.site.register(models.EventLog,EventLogAdmin)
admin.site.register(models.NewAssetApprovalZone,NewAssetApprovalZoneAdmin)

ContentType是对app和其中的表做了进步一抽象，可以实现对于model的动态调用;
