傳遞給函數的laravel值不會傳遞到數據庫中

Question

我在laravel中有一個用於將數據保存到數據庫中的函數，出於某種原因，其中一個變量將不會添加到數據庫中，特別是日曆的id 。我曾嘗試在數據庫輸入前後返回變量，並且在兩次都存在，它不會被添加。以下是我迄今爲止：

class SetupPhotoshoot{ 

public function createListing(Request $request){ 

$calendarAdd = $this->addToCalendar($request); 

$addtoDB = $this->addToDB($request, $calendarAdd['id']); 

return $addtoDB; 

    } 
protected function addToDB($request, $calendarID){ 

    //Some code here 

    return $calendarID; //This is to see if the id exists inside the function, which it does. 

    $newSchedule = new Schedule; 

    $addtoDB = $newSchedule->create({ 
    //Add a bunch of fields 
    'services_id' => $request->Package, 
    'appt_time' => $request->DateTime, 
    'total' => $request->total, 
    'calendar_id' => $calendarID //This is where I want the id to be added, but it isn't working. 
}); 

    return $calendarID; //I tried returning after adding to DB to see if it somehow got lost between before adding to DB and after, but it still returned. 

//NOTE: the two individual returns were NOT used at the same time. I commented out one to test if the other returned, so it IS NOT because I used return multiple times. 

    } 

} 

所有其他數據被添加到數據庫中正確的，除了calendar_id.它說，特定的錯誤是「常規錯誤：1364字段‘CALENDAR_ID’沒有缺省值「。當我允許空值時，它只會將「null」添加爲數據庫中的值。下面是它看起來像在數據庫中（這是MYSQL）：

Name: calendar_id 

Type: varchar(191) utf8mb4_unicode_ci 

Null: Yes 

Default: None

'calendar_id' doesn't have a default value

$calendarID沒有被通過，也許這是空，用dd($calendarID)以確保它被設置。

create()也是一個靜態方法，所以不要創建的Schedule 一個實例，你可以靜態Schedule::create($data)調用它。

你的模型，確保calendar_id是你可填寫陣列的一部分：

protected $fillable = [ 
    'services_id', 
    'appt_time', 
    'total', 
    'calendar_id' 
];
