【问题描述】：

我正面临这个错误：我正在使用 django-import-export 包。问题是我在导入方面找不到太多文档，我希望能够使用它将数据导入我的应用程序。

Line number: 1 - 'id'

这是我的 Excel 工作表文件：

这是我的模型资源

class IncidenceReport(resources.ModelResource):

    class Meta:
        model = Incidence

        skip_unchanged = True
        report_skipped = True
        import_id_fields = ['id']
        fields = ('country__name', 'state__name', 'city__name', 'created_at', 'updated_at',
                  'reporter_name', 'reporter_email', 'reporter_phone', 'description',
                  'street_address', 'date_of_incidence', 'name_of_officers',)


class IncidenceAdmin(ImportExportModelAdmin, admin.ModelAdmin):
    resource_class = IncidenceReport
    autocomplete_fields = ("country", "state", "city")
    list_display = [field.name for field in Incidence._meta.fields]
    search_fields = ['country__name', 'state__name', 'city__name', 'description',
                     'street_address', 'is_rep_needed', 'is_victim']
    list_filter = ('created_at', 'updated_at',  'is_rep_needed', 'is_victim')

【解决方案1】：

这可能是因为您没有在字段列表中列出“id”（即import_id_fields 值）：

class IncidenceReport(resources.ModelResource):

    class Meta:
        model = Incidence

        skip_unchanged = True
        report_skipped = True
        import_id_fields = ['id']
        # declare 'id' in this tuple:
        fields = ('id', 'country__name', ...)

我已经解决了这个问题。问题是我在excel表上添加了id字段
