示例需求:
1:查询所有的商品列表下的对应的图片
使用点:
1:使用了dicts()和没使用dicts()的有很大的区别
2:连表中有相同的字段重名的重新命名alias的使用
query1 = FloweshopGoods.select(FloweshopGoodsImages.images_id.alias('图片XXX'), FloweshopGoodsImages.goods_id, FloweshopImages.name.alias('XXXXXXXXXXXX'), FloweshopGoods).join(FloweshopGoodsImages, on=(
FloweshopGoodsImages.images_id == FloweshopGoods.image_id)) \
.join(FloweshopImages, on=(FloweshopGoodsImages.images_id == FloweshopImages.id)).dicts()
查询的结果为:
