推荐答案
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"，并排除了在resources.py
Seems "django-import-export" still using the default one 'id'. for the time been, included a column 'id' in the header in CSV file and excluded importing in resources.py
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')
