Yii2 过滤具有多重关系的数据

Question

我正在制作和列出船只有两种类型的船只页面

• 共享。
• 私人。

如果有共享船只

我必须检查

• 如果他们提供半天 (1/2) 行程，则显示半天价格。
• 如果半天不可用，请检查是否为一天的四分之三 (3/4)，价格是否为一天的四分之三。
• 否则检查全天并获取全天价格。

如果共享船不可用

• 检查是否有可用的私人船只。
• 然后对私人船只应用上面给出的相同方案。

对于这些定价，我使用了条件，但在过滤从高到低/从低到高的价格过滤时，我不知道如何应用条件。有人可以帮我解决这些问题。

型号：

• Boatinformation(Main).

• Boatsharedfishingtrip(shared pricing)

• Boatfishingcharter(Private Pricing)

模型关系：

public function getBoatfishingcharter() {
    return $this->hasOne(Boatfishingcharter::className(), ['boat_id' => 'boat_id']);
}

public function getBoatsharedtrip() {
    return $this->hasOne(Boatsharedfishingtrip::className(), ['boat_id' => 'boat_id']);
}

if($model->boatsharedtrip->shared_fishing_charters == '1') {
    if($model->boatsharedtrip->one_two_day_4hrs == 1) {
        $shared_price = $model->boatsharedtrip->one_two_day_rate_per_angler;
    } else if($model->boatsharedtrip->three_four_day_6hrs == 1) {
        $shared_price = $model->boatsharedtrip->three_four_day_rate_per_angler;
    } else if($model->boatsharedtrip->full_day_8hrs == 1) {
        $shared_price = $model->boatsharedtrip->full_day_rate_per_angler;
    }
} else if($model->boatfishingcharter->private_fishing_charters == 1) {

    if($model->boatfishingcharter->one_two_day_4hrs == 1) {
        $private_price = $model->boatfishingcharter->one_two_day_rate;
    } else if($model->boatfishingcharter->three_four_day_6hrs == 1) {
        $private_price = $model->boatfishingcharter->three_four_day_rate;
    } else if($model->boatfishingcharter->full_day_8hrs == 1) {
        $private_price = $model->boatfishingcharter->full_day_rate;
    }
}

对于我目前使用的过滤器：

if($_GET['orderby'] == 'price_desc') {
    $query->orderBy(['one_two_day_rate_per_angler' => SORT_DESC, 'one_two_day_rate' => SORT_DESC, 'three_four_day_rate_per_angler' => SORT_DESC, 'three_four_day_rate' => SORT_DESC, 'full_day_rate_per_angler' => SORT_DESC, 'full_day_rate' => SORT_DESC]);
} elseif($_GET['orderby'] == 'price_asc') {
    $query->orderBy(['one_two_day_rate_per_angler' => SORT_ASC, 'one_two_day_rate' => SORT_ASC, 'three_four_day_rate_per_angler' => SORT_ASC, 'three_four_day_rate' => SORT_ASC, 'full_day_rate_per_angler' => SORT_ASC, 'full_day_rate' => SORT_ASC]);
}


$query = Boatinformation::find();
        $query->leftJoin('boatsharedfishingtrip', '`boatsharedfishingtrip`.`boat_id` = `boatinformation`.`boat_id`')
              ->leftJoin('rating_review', '`rating_review`.`boat_id` = `boatinformation`.`boat_id`')
              ->leftJoin('boatotherservice', '`boatotherservice`.`boat_id` = `boatinformation`.`boat_id`')
              ->leftJoin('boatfishingequipment', '`boatfishingequipment`.`boat_id` = `boatinformation`.`boat_id`')
              ->join('INNER JOIN','boatcompanyinformation', '`boatcompanyinformation`.`id` = `boatinformation`.`boat_id`')
              ->leftJoin('boatfishingcharter', '`boatfishingcharter`.`boat_id` = `boatinformation`.`boat_id`')
              ->where(['boat_publish' => 1])->all();

编辑

这就是我在列表中显示船只的方式

Answer 1

我是否正确理解表之间的关系类型是“一对一”？ 我的意思是 Boatinformation、Boatsharedfishingtrip 和 Boatfishingcharter？

试试这个。

// Main query
$query = Boatinformation::find()
    ->leftJoin('boatsharedfishingtrip', '`boatsharedfishingtrip`.`boat_id` = `boatinformation`.`boat_id`')
    ->leftJoin('rating_review', '`rating_review`.`boat_id` = `boatinformation`.`boat_id`')
    ->leftJoin('boatotherservice', '`boatotherservice`.`boat_id` = `boatinformation`.`boat_id`')
    ->leftJoin('boatfishingequipment', '`boatfishingequipment`.`boat_id` = `boatinformation`.`boat_id`')
    ->join('INNER JOIN', 'boatcompanyinformation', '`boatcompanyinformation`.`id` = `boatinformation`.`boat_id`')
    ->leftJoin('boatfishingcharter', '`boatfishingcharter`.`boat_id` = `boatinformation`.`boat_id`')
    ->where(['boat_publish' => 1]);


// Sort
$orderBy = Yii::$app->request->get('orderby');

switch ($orderBy) {
    case 'price_desc':
        $query->orderBy(['one_two_day_rate_per_angler' => SORT_DESC, 'one_two_day_rate' => SORT_DESC, 'three_four_day_rate_per_angler' => SORT_DESC, 'three_four_day_rate' => SORT_DESC, 'full_day_rate_per_angler' => SORT_DESC, 'full_day_rate' => SORT_DESC]);
        break;

    case 'price_asc':
        $query->orderBy(['one_two_day_rate_per_angler' => SORT_ASC, 'one_two_day_rate' => SORT_ASC, 'three_four_day_rate_per_angler' => SORT_ASC, 'three_four_day_rate' => SORT_ASC, 'full_day_rate_per_angler' => SORT_ASC, 'full_day_rate' => SORT_ASC]);
        break;
}


// Execute
// var_dump( $query->createCommand()->getRawSql() );  // Uncomment to debug built SQL

$query->all();

你在使用 Yii2 调试工具栏吗？如果是这样，请在此处复制粘贴构建 SQL。 如果不是，请取消注释 getRawSql 行。它可能有助于弄清楚为什么它不适合您。
