Question

我有一个系统，用户需要能够更改产品。但问题是，这个产品与主题有多态关系。这是积累

Products
    - ID
    - productable_id (For instance "1")
    - productable_type (Is either "App\Theme"or "App\Plugin")
    - name (Just a name)
    - description (Just a description)
    - etc
Theme
    - id (1)
    - composer_package

现在我需要用户能够更改产品。目前，我在控制器中完成了这样的操作

public function update(Request $request, $id)
{
    $product = Product::find($id);
    $product->fill($request->all());

    $product->save();

    return redirect('/products')->with('flash', $product->name . ' is succesvol bewerkt');
}

但由于它的多态关系，我不知道如何改变，例如＆＃34; composer_package＆＃34;与所选产品相关联的。比方说，我想更改ID为1的产品。然后我还希望能够更改id为1的composer_package，因为那个与所选产品相关联。另外，我如何更改产品的类型。所选产品为App\Theme，我想将其更改为App\Plugin。如何通过这种多态关系实现上述两件事

这是收集数据的表单。它非常大

修改

产品型号

class Product extends Model
{

protected $fillable = [
    'productable_type', 'productable_id', 'name', 'description', 'thumbnail', 'price', 'periodically_price', 'period_id'
];

public function productable()
{
    return $this->morphTo();
}

public function order_items()
{
    return $this->hasMany(Orderitems::class);
}

public function plan() {
    return $this->belongsTo(Plan::class, 'period_id');
}

}

主题模型

class Theme extends Model
{

protected $fillable = [

];

public function webshops()
{
    return $this->hasMany(Webshop::class);
}

public function products()
{
   return $this->morphMany(Product::class, 'productable');
}
}

Answer 1

将composer_package添加到Theme::$fillable。

调整HTML表单：name="productable[composer_package]"

然后你可以像这样更新主题：

$product->productable->update($request->get('productable'))
