python - django-import-export: cannot exclude id field during import : KeyError: u'id'

On Django-1.9.6, django-import-export-0.5

When I try to upload CSV without "id" field throws this error.

Line number: 1 - u'id'

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')
