如何在updateOrCreate雄辩中添加laravel查询功能列表

Question

我试图将updateOrCreate与多个条件一起使用，并且如果有相应的数据可用，则可以偶尔应用此条件。 我目前正在做的事情是先找到id是否存在，如果id存在，则更新，否则手动创建，但是现在我想使用laravel给定的updateOrCreate函数。

$existing = Student::where('name_last', $student['name_last'])
->where('name_first', $student['name_first'])
->where(function($query) use ($student) {
    if (array_key_exists('phone_preferred', $student) && !empty($student['phone_preferred'])) {
        $query->where('phone_preferred', $student['phone_preferred']);
    }

    if (array_key_exists('email_preferred', $student) && !empty($student['email_preferred'])) {
        $query->where('email_preferred', $student['email_preferred']);
    }

    if (array_key_exists('home_street_address_1', $student) && !empty($student['home_street_address_1'])) {
        $query->where('home_street_address_1', $student['home_street_address_1']);
    }

    if (array_key_exists('mailing_street_address_1', $student) && !empty($student['mailing_street_address_1'])) {
        $query->where('mailing_street_address_1', $student['mailing_street_address_1']);
    }

    if (array_key_exists('mailing_address_city', $student) && !empty($student['mailing_address_city'])) {
        $query->where('mailing_address_city', $student['mailing_address_city']);
    }

})->first();

 if($existing){
    try{
        Student::where('id', $existing->id)
        ->update($student);
        } catch (\Exception $e) {
         $error_encountered = true;
         $error_arr[] = $e->getMessage();
         $error_row_numbers[] = $row_no; 
        }
}

我想用类似的东西来实现：

try{
        Student::updateOrCreate(
                     ['name_first' => $student['name_first], 'name_last' => $student['name_last]], 
                    $student
           ); //I could not get how to implement other occasional where condition

        } catch (\Exception $e) {
         $error_encountered = true;
         $error_arr[] = $e->getMessage();
         $error_row_numbers[] = $row_no; 
        }

我想包括那些偶尔在哪里查询功能的updateOrCreate方法，目前正在手动方法中实现

您可以仅将要检查的所有属性添加到传递给updateOrCreate的数组中

// these are your required conditions
$conditions = [
    'name_first' => $student['name_first'],
    'name_last' => $student['name_last'],
];

// these are optional
$attributes = [
    'phone_preferred', 
    'email_preferred', 
    'home_street_address_1', 
    'mailing_street_address_1', 
    'mailing_address_city'
];

foreach($attributes as $attr){
    // check to see if the attribute exists on the student
    // and is not empty
    if(isset($student[$attr]) && !empty($student[$attr])){
        $conditions[$attr] = $student[$attr];
    }
}

Student::updateOrCreate($conditions);
