関係:
Shop.hasMany(ShopAd, {foreignKey : 'shop_id', as : 'ads'});
ShopAd.belongsTo(Shop, {foreignKey : 'id'})
私は使用しています:
Shop.findAll({where:{id:shopId}, include:[{model:ShopAd, as:'ads', where:{is_valid:1, is_vertify:1}}]}).success(function(result) {
callback(result);
});
しかし、SQLは次のとおりです。
SELECT `Shop`.`id`, `Shop`.`user_id`, `Shop`.`short_name`, `Shop`.`description`, `Shop`.`tips`, `Shop`.`city`, `Shop`.`province`, `Shop`.`address`, `Shop`.`logo`, `Shop`.`publicity_photo`, `Shop`.`taobao_link`, `Shop`.`is_vertify`, `Shop`.`create_time`, `Shop`.`update_time`, `ads`.`id` AS `ads.id`, `ads`.`shop_id` AS `ads.shop_id`, `ads`.`pic_url` AS `ads.pic_url`, `ads`.`description` AS `ads.description`, `ads`.`link` AS `ads.link`, `ads`.`is_valid` AS `ads.is_valid`, `ads`.`is_vertify` AS `ads.is_vertify`, `ads`.`create_time` AS `ads.create_time`, `ads`.`update_time` AS `ads.update_time` FROM `weshop_shop` AS `Shop` INNER JOIN `weshop_shop_advertsing` AS `ads` ON `Shop`.`id` = `ads`.`shop_id` AND `ads`.`is_valid`=1 AND `ads`.`is_vertify`=1 WHERE `Shop`.`id`='1';
「LEFT JOIN」を使いたいのですが、どうしたらいいですか?
使用:required:false
文:
Shop.findAll({
where:{id:shopId},
include:[
{ model:ShopAd, as:'ads',
where:{
is_valid:1,
is_vertify:1},
required:false
}
]
})
.success(function(result) {
callback(result);
});
required: true
はINNER JOIN
を強制します。required: false
を使用してLEFT JOIN
を強制します。
