在 Yii 2.0 中，需要同时基于 MySQL ActiveRecord 与 Redis ActiveRecord 查询资源的实现

1、在 Postman 中，打开网址：http://api.pcs-api.localhost/v1/plan-config-column-users?login_id=2e368664c41b8bf511bcc9c65d86dbc3&login_tid=685f805f71faedfe215f55bbb01b50c6&filter[config_column_id]=1 ，仅支持字段：config_column_id 的查询，响应如下：

{
    "code": 10000,
    "message": "获取选题栏目人员配置列表成功",
    "data": {
        "items": [
            {
                "id": 1,
                "group_id": "015ce30b116ce86058fa6ab4fea4ac63",
                "user_id": 8,
                "config_column_id": 1,
                "login_name": "13281105967",
                "user_nick": "13281105967_nick",
                "user_mobile": "13281105967",
                "role_code": "column_manager",
                "status": 1,
                "is_not_isolated": 0,
                "is_deleted": 0,
                "created_at": 1556526988,
                "updated_at": 1556536370,
                "deleted_at": 0,
                "user_pic": "https://pgcupload.flydev.chinamcloud.cn/uploads/cmc_user_avatar/20190219/1550570817-4LLQJJ.png"
            },
            {
                "id": 4280,
                "group_id": "015ce30b116ce86058fa6ab4fea4ac63",
                "user_id": 29,
                "config_column_id": 1,
                "login_name": "cgl",
                "user_nick": "cgl_nick",
                "user_mobile": "",
                "role_code": "default_role",
                "status": 1,
                "is_not_isolated": 0,
                "is_deleted": 0,
                "created_at": 1562569842,
                "updated_at": 1562569842,
                "deleted_at": 0,
                "user_pic": "https://pgcupload.flydev.chinamcloud.cn/uploads/cmc_user_avatar/default_header.png"
            },
            ...
        ],
        "_links": {
            "self": {
                "href": "http://api.pcs-api.localhost/v1/plan-config-column-users?login_id=2e368664c41b8bf511bcc9c65d86dbc3&login_tid=685f805f71faedfe215f55bbb01b50c6&filter%5Bconfig_column_id%5D=1&per-page=1023&page=1"
            }
        },
        "_meta": {
            "totalCount": 1023,
            "pageCount": 1,
            "currentPage": 1,
            "perPage": 1023
        }
    }
}

2、SQL 语句如下：

SELECT * FROM `pa_config_column_user` WHERE (`config_column_id` IN (SELECT `pa_config_column`.`id` FROM `pa_config_column` LEFT JOIN `pa_config_column_user` ON `pa_config_column`.`id` = `pa_config_column_user`.`config_column_id` AND `pa_config_column_user`.`user_id` = '8' WHERE (`pa_config_column`.`is_deleted`=0) AND (`pa_config_column`.`status`=1) AND (`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1) AND (`pa_config_column_user`.`user_id`='8') ORDER BY `pa_config_column`.`id` DESC)) AND ((`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1)) AND (`config_column_id`='1') LIMIT 1023

3、现有新的需求，需要支持字段：user_nick 的模糊查询，但是字段：user_nick 不存在于 MySQL ActiveRecord 中，而是存在于 Redis ActiveRecord 中。且 Redis ActiveRecord 不支持 like 操作符。如图1

图1

4、虽然 Redis ActiveRecord 不支持 like 操作符，但是其支持 in 操作符，因此，决定先支持字段：config_column_id 的查询，在此查询结果中，获取所有用户的 user_id(MySQL)，然后基于 in 操作符获取到 Redis ActiveRecord 的所有用户的 user_nick(Redis)。

        // 判断用户昵称是否为空，如果不为空，则查询当前分页的框架服务控制台用户列表，然后基于用户昵称模糊搜索
        if (!$filterUserNickIsEmpty) {
            $likeQuery = clone $query;
            $configColumnUserUserIds = $likeQuery->select(['user_id'])->asArray()->column();
            print_r($configColumnUserUserIds);

            /* 查询当前分页的框架服务控制台用户列表 */
            $redisCmcConsoleUserItems = RedisCmcConsoleUser::find()->where(['in', 'id', $configColumnUserUserIds])->indexBy('id')->asArray()->all();
            $redisCmcConsoleUserUserNicks = ArrayHelper::getColumn($redisCmcConsoleUserItems, 'user_nick');
            print_r($redisCmcConsoleUserUserNicks);
            exit;
        }

Array
(
    [0] => 8
    [1] => 29
    ...
)

Array
(
    [8] => 13281105967_nick
    [29] => cgl_nick
    ...
)

5、使用 PHP 过滤类似于 SQL LIKE’％search％’ 的数组中的值，参考问答：filter values from an array similar to SQL LIKE ‘%search%’ using PHP，网址：https://stackoverflow.com/questions/5808923/filter-values-from-an-array-similar-to-sql-like-search-using-php ，如图2

图2

        // 判断用户昵称是否为空，如果不为空，则查询当前分页的框架服务控制台用户列表，然后基于用户昵称模糊搜索
        if (!$filterUserNickIsEmpty) {
            $likeQuery = clone $query;
            $configColumnUserUserIds = $likeQuery->select(['user_id'])->asArray()->column();

            /* 查询当前分页的框架服务控制台用户列表 */
            $redisCmcConsoleUserItems = RedisCmcConsoleUser::find()->where(['in', 'id', $configColumnUserUserIds])->indexBy('id')->asArray()->all();
            $redisCmcConsoleUserUserNicks = ArrayHelper::getColumn($redisCmcConsoleUserItems, 'user_nick');

            // 使用 PHP 过滤类似于 SQL LIKE'％search％' 的数组中的值
            $input = preg_quote($filterUserNick, '~'); // don't forget to quote input string!
            $redisCmcConsoleUserLikeUserNicks = preg_grep('~' . $input . '~', $redisCmcConsoleUserUserNicks);

            print_r($redisCmcConsoleUserLikeUserNicks);
            exit;
        }

Array
(
    [8] => 13281105967_nick
)

6、在 Postman 中，打开网址：http://api.pcs-api.localhost/v1/plan-config-column-users?login_id=2e368664c41b8bf511bcc9c65d86dbc3&login_tid=685f805f71faedfe215f55bbb01b50c6&filter[config_column_id]=1&filter[user_nick][like]=test ，基于用户昵称模糊搜索获取到：$redisCmcConsoleUserLikeUserNicks，再获取其数组键，作为新的搜索条件，最终生成的 SQL 如下：符合预期，如图3

图3

        // 判断用户昵称是否为空，如果不为空，则查询当前分页的框架服务控制台用户列表，然后基于用户昵称模糊搜索
        if (!$filterUserNickIsEmpty) {
            $likeQuery = clone $query;
            $configColumnUserUserIds = $likeQuery->select(['user_id'])->asArray()->column();

            /* 查询当前分页的框架服务控制台用户列表 */
            $redisCmcConsoleUserItems = RedisCmcConsoleUser::find()->where(['in', 'id', $configColumnUserUserIds])->indexBy('id')->asArray()->all();
            $redisCmcConsoleUserUserNicks = ArrayHelper::getColumn($redisCmcConsoleUserItems, 'user_nick');

            // 使用 PHP 过滤类似于 SQL LIKE'％search％' 的数组中的值
            $input = preg_quote($filterUserNick, '~'); // don't forget to quote input string!
            $redisCmcConsoleUserLikeUserNicks = preg_grep('~' . $input . '~', $redisCmcConsoleUserUserNicks);

            $query->andWhere(['in', 'user_id', array_keys($redisCmcConsoleUserLikeUserNicks)]);
        }

SELECT * FROM `pa_config_column_user` WHERE (`config_column_id` IN (SELECT `pa_config_column`.`id` FROM `pa_config_column` LEFT JOIN `pa_config_column_user` ON `pa_config_column`.`id` = `pa_config_column_user`.`config_column_id` AND `pa_config_column_user`.`user_id` = '8' WHERE (`pa_config_column`.`is_deleted`=0) AND (`pa_config_column`.`status`=1) AND (`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1) AND (`pa_config_column_user`.`user_id`='8') ORDER BY `pa_config_column`.`id` DESC)) AND ((`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1)) AND (`config_column_id`='1') AND (`user_id` IN (185, 186, 187, 191, 194, 204, 205, 206, 207, 208, 1051, 1177, 1178, 1180, 1220, 1339)) LIMIT 16
