django-import-export：无法在导入过程中排除 id 字段：KeyError: u'id'

Question

在 Django-1.9.6 上，django-import-export-0.5

当我尝试上传没有“id”字段的 CSV 时会引发此错误。

似乎“django-import-export”仍在使用默认的“id”。目前，在 CSV 文件的标题中包含一列“id”，并排除在 resources.py 中的导入

class edxUserResource(resources.ModelResource):

    class Meta:
        model = edxUser
        skip_unchanged = True
        report_skipped = True
        exclude = ('id',)
        import_id_fields = ('edx_id', 'edx_email', 'edx_name',)
        #export_order = ('edx_id', 'edx_email')
