目前有两种比较推荐的方法:

  1. 重写export方法在export方法中将表头及数据造出来,只需要将数据写入列表中即可,推荐使用sql,连表查询比较灵活,需要注意的是表头要和数据一一对应,不然报错:
class IncomingValuableGroupViewResource(resources.ModelResource):
    class Meta:
        model = IncomingValuableGroupView
        # fields = ('id', 'author_name',)

    def export(self, queryset=None, *args, **kwargs):
        headers = ['序号', '日期', '清点SKU种类', '清点SKU数量', '质检SKU种类', '质检SKU数量', '加工SKU种类', '加工SKU数量', '上架SKU种类', '上架SKU数量',
                   '目的仓库']
        data = tablib.Dataset(headers=headers)
        from django.db import connection
        cr = connection.cursor()
        sql = """
                select A.id,
                       A.create_date_without_time,
                       A.count_product_check,
                       A.sum_actual_check_qty,
                       A.count_product_quality,
                       A.sum_actual_quality_qty,
                       A.count_product_processing,
                       A.sum_actual_processing_qty,
                       A.count_product_shelves,
                       A.sum_actual_shelves_qty,
                       B.name as location_name
                from incoming_valuable_group_view as A,
                     stock_location as B
                where A.location_id = B.id;
        """
        cr.execute(sql)
        res = cr.fetchall()

        for insert_data in res:
            data.append(insert_data)

        self.after_export(queryset, data, *args, **kwargs)

        return data
  1. 我目前没有使用过,但也挺简单的,不需要重写​​export​​方法,直接在数据库中创建视图,并在项目中创建相应的模型,视图,按照常规的文件下载方式设置即可,这里比较麻烦的是需要重新创建模型,但是以后维护方便,以后加减字段,调整逻辑比较方便.

懂得,原来世界如此简单!
