Question

Country.hasMany(City, { foreignKey: 'country_id' });
City.belongsTo(Country, { foreignKey: 'country_id' });
City.hasMany(Walk, { foreignKey: 'city_id' });
Walk.belongsTo(City, { foreignKey: 'city_id' });
Walk.hasMany(Point, { foreignKey: 'walk_id' });

查询字段：

walks: Db.models.dl_walk.findAll({
    where: {
        $or: [
            {
                name: { like: `%${args.search}%` }
            }
        ]
    }
})

search="NameCountry"时，如何获取当前国家和所有＆＃34;行走＆＃34;
在当前的国家？

Answer 1

要查找属于某个国家/地区的所有步行，您需要进行关联查询 像

这样的东西

Model.Country.findAll({where:/*some criteria*/, 
  include:[{model: Model.city, include: model.walk}]
})

这将使联接查询从国家/地区开始到步行
