Question

我有item_color和item_size数据透视表，并希望使用其字段值更新我的大小和颜色字段，并且不确定从何处开始。这是我到目前为止所拥有的。

ItemSize.php

<?php

class ItemSize extends \Eloquent
{
    protected $table = 'item_size';
    protected $fillable = [];

    public function item() {
        return $this->belongsTo('Item');
    }
}

ItemColor.php

<?php

class ItemColor extends \Eloquent
{
    protected $table = 'item_color';
    protected $fillable = [];

    public function item() {
        return $this->belongsTo('Item');
    }
}

VendorController

public function postVendorUpdateItems ($id)
         {

             $input     = Input::all();

             $items = Item::find($id);
             $validator = Validator::make($input, 
               [ 'item_name'     => 'max:50',
                 'item_id'       => 'max:50',
                 'normalprice'   => 'numeric',
                 'karmaprice'    => 'numeric',
                 'asin'          => 'max:50',
               ]);

             if($validator->passes())
             {

                 $items->name           = $input['item_name'];
                 $items->normalprice    = $input['normalprice'];
                 $items->karmaprice     = $input['karmaprice'];
                 $items->asin           = $input['asin'];
                 $items->id             = $input['item_id'];
                 $items->save();
                 return Redirect::route('account-vendor-index')
                                ->with('global', 'You have updated your item.');
             }

             return Redirect::route('account-vendor-index')
                            ->withErrors($validator)
                            ->with('global', 'Your item could not be updated.');
         }

Answer 1

item_size和item_color不是数据透视表。事实上，它们与您的架构是一对一的关系。如果您真的想要透镜表，则需要定义颜色和尺寸表，然后创建多对多关系。见这里：https://laravel.com/docs/master/eloquent-relationships

然后要更新相关模型，您将使用附加，同步，分离等方法。

另外，你在运行什么版本的Laravel？如果您正在运行5.1+，请查看表单请求验证。见这里：https://laravel.com/docs/master/validation#form-request-validation

这将从控制器中删除所有验证逻辑。
