为什么 performInsert() 从数组中删除字段？

Question

我不明白为什么 performInsert() 会在 Laravel 5.2 中删除我的 '_logo' 字段。 我的模型除了“id”、“created_at”和“updated_at”之外的所有东西都可以填写。

(2/2) QueryException

SQLSTATE[HY000]: General error: 1364 Field '_logo' doesn't have a default value (SQL: insert into `LC_portatori` (`nome`, `cognome`, `tipo`, `pwd`, `telefono`, `indirizzo`, `email`, `updated_at`, `created_at`) values (Nome, CognomE, TipO, PwD, TelefonO, IndirizzO, emaiL, 2017-06-30 11:37:52, 2017-06-30 11:37:52))

更新

我基本上是这样处理requests Form中的每一个字段的：

public function store(Request $request){
    unset($request["_token"]);

    //get table name
    $tableName     = $request->segment(TABLE_SEGMENT);
    //convert to a class object
    $className     = 'App\\' . studly_case(str_singular($tableName));
    if(class_exists($className)) {
        $model = new $className;
        $model::create($request->all());
    }
}

我的模型是：

namespace App;

use Illuminate\Database\Eloquent\Model;

class Portatore extends Model
{
    //
    protected $table    = 'portatori';
    protected $guarded  = ['id','created_at','updated_at'];


}

我的表单是从模型字段开始构建的，因此我将每个字段都提供给表单，然后将它们检索回存储函数

Answer 1

查看无法添加_logo 的原因是它以_ 开头并且不在可填充数组中。当可填充数组为空时，Laravel 将允许任何不受保护且不以 _ 开头的列。

您可以：

• 从列名中删除_

• 明确说明列是可填充的，即：

  protected $fillable = ['nome', 'cognome', 'tipo', 'pwd', 'telefono', 'indirizzo', 'email', '_logo']; //and any other columns that are allowed (if any)
  

• 手动将_logo 值添加到实例，即$model->_logo = $request['logo'];。 （不过，这可能会导致您的动态方法出现“代码异味”）

希望这会有所帮助！
