Laravel update() 在 foreach 中不工作，即使我声明了 $fillable

Question

我这里有一些相当难看的代码：

foreach($request->assigned['standards'] as $standard){
            if(@$standard['plannings']) {
                foreach($standard['plannings'] as $p) {
                    dump($p['id']);
                    $assigned = PerformanceManagementSetModuleStandardAssignedPlanning::
                        where('id', $p['id'])
                        ->where('performance_management_set_assigned_id', $request->assigned_id)
                        ->first();
                    $assigned->text = $p['text'];
                    $assigned->user_id= 1; //I did this to check that the model was updating, it was
                    dump($assigned);
                    $assigned->update();
                }
            }
        }

记录正在更新，除“文本”栏外的所有内容。我手动更新了“user_id”列只是为了确保，这个更新非常好。

我有可填写的文字属性:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class PerformanceManagementSetModuleStandardAssignedPlanning extends Model
{
    use HasFactory;

    protected $fillable = [
        'text',
    ];
}

我转储的时候也可以看到这里(dump($assigned)):

App\Models\PerformanceManagementSetModuleStandardAssignedPlanning {#1611
  #fillable: array:1 [
    0 => "text"
  ]
  #connection: "mysql"

    "user_id" => 233
    "text" => null
    "created_at" => "2022-05-12 10:06:24"
    "updated_at" => "2022-05-12 10:28:14"

}

这里有什么我遗漏的简单的东西吗？

Answer 1

您可以使用 save() 方法进行该更新。

foreach($request->assigned['standards'] as $standard){
            if(@$standard['plannings']) {
                foreach($standard['plannings'] as $p) {
                   
                    $assigned = PerformanceManagementSetModuleStandardAssignedPlanning::
                        where('id', $p['id'])
                        ->where('performance_management_set_assigned_id', $request->assigned_id)
                        ->first();
                    $assigned->text = $p['text'];
                    $assigned->user_id= 1; //I did this to check that the model was updating, it was
                    $assigned->save();
                     dump($assigned);
                }
            }
        }

原来循环是什么覆盖，每次都传递相同的ID。感谢您的帮助！
