django-import-export从'1'开始按顺序指定id

Question

当我从excel导入数据时，我发现默认ID是随机的：

ID   NAME
5    A
9    B

我希望它在导入数据时看起来像下面的示例＆＃34; NAME：A，NAME：B＆＃34;来自excel：

ID   NAME
1    A
2    B

我该怎么做？

class assets_resource(resources.ModelResource):

class Meta:
    model = assets
    skip_unchanged = True   
    report_skipped = False

@admin.register(assets)
class data_import(ImportExportModelAdmin):
    list_display = ['id', 'sn']
    search_fields = ['id', 'sn']
    ordering = ['id', 'sn']
    resource_class = assets_resource
