Question

我正在开发一个API，我从移动应用程序获取表单数据到将其存储在数据库表$datetime = new DateTime('2017-01-20T13:59:19+03:00', new DateTimeZone('Asia/Kolkata')); $new = $datetime->format('Y-m-d H:i:s e'); $arr = (explode(" ",$new)); $arr2 = explode(":",$arr[1]); $arr3 = explode(":",$arr[2]); $vicky = $arr2[0]+$arr3[0]; $arr2[0] = $vicky; $finaltime = (implode(":",$arr2)); $final = $arr[0].' '.$finaltime; echo $final;中我希望在将数据存储到数据库之前修改列workers数据

在我的控制器中我就像这样存储

registration_id

在我的模型中，我试图将public function store() { Driver::create(input::all()); return $this->respondCreated('Driver created successfully'); }值更改为

registration_id

但它不能正常工作原始表单值插入数据库如何将<?php namespace App; use Illuminate\Database\Eloquent\Model; use Illuminate\Database\Eloquent\SoftDeletes; class Driver extends Model { use SoftDeletes; protected $fillable = [ 'agent_id', 'registration_center', 'sponsor_name', 'event_name', 'registration_id', ]; protected $dates = ['deleted_at']; public function modifyRegistrationId($registration_id) { $this->attributes['registration_id'] = 'test'; } }更改为其他值

期待急需的帮助

谢谢

Answer 1

如果您始终覆盖该值define a mutator：

public function setRegistrationIdAttribute($value)
{
    $this->attributes['registration_id'] = 'test';
}

如果您只想这样做一次，请覆盖以下值：

public function store(Request $request)
{
    $request->registration_id = 'test';
    Driver::create($request->all());

    return $this->respondCreated('Driver created successfully');
}

您可以在保存之前使用事件来更改任何数据。看看Laravel docs。这里我们使用boot()定义回调行为：

class Driver extends Model 
{

    public static function boot()
    {
        parent::boot();

        self::creating(function($model){
            //before create, do this...
            $lastRegistrationId = Driver::orderBy('id', 'desc')->first()->registration_id;
            $this->registration_id = $lastRegistrationId.date('Y-m-d');
        });
    }
    ...
}

您可以使用的功能包括：创建，创建，更新，更新，保存，保存，删除，删除，恢复，恢复
