Laravel表单模型绑定，相关表值

Question

关于输入字段并使用Form::model()绑定检索相关数据。我怎样才能做到这一点？文本输入qty上的绑定结果为空。我可以从model()

开始思考模型中的黑客行为

表格（app / views / products / edit.blade.php）

{{ Form::model($product, array(
  'method' => 'PATCH', 
  'route' => array('products.update', $product->id),
  'class' => 'form-inline'
)) }}
{{ Form::label('name', 'Name:') }}
{{ Form::text('name') }}
{{ Form::label('qty', 'Price:') }}
{{ Form::text('qty') }} <!-- here's da thing! -->
{{ Form::submit('Update', array('class' => 'btn btn-info')) }}
{{ Form::close() }}

应用程序/控制器/ ProductsController.php

class ProductsController extends BaseController {
  public function edit($id) {
    $product = Product::find($id);
    if (is_null($product)) return Redirect::route('products.index');
    return View::make('products.edit', compact('product'));
  }
}

应用程序/模型/

class Product extends Eloquent {
  public $timestamps = false;
  protected $fillable = array('name');

  public function prices() {
    return $this->hasMany('Price');
  }
  public function images() {
    return $this->morphMany('Image', 'imageable');
  }
}
class Price extends Eloquent {
  protected $table = 'product_prices';
  public $timestamps = true;
  protected $fillable = array('qty');

  public static $rules = array(
    'qty' => 'required|numeric'
  );

  public function product() {
    return $this->belongsTo('Product');
  }

}

Answer 1

您确定$product上有数据吗？

Route::get('/test', function() {

    $user = new User;
    $user->email = 'me@mydomain.com';
    return View::make('test', compact('user'));

});

查看（test.blade.php）：

{{ Form::model($user, array(
  'method' => 'PATCH', 
)) }}
{{ Form::label('email', 'E-mail:') }}
{{ Form::text('email') }} <!-- here's da thing! -->
{{ Form::submit('Update', array('class' => 'btn btn-info')) }}
{{ Form::close() }}

结果：

Answer 2

Laravel表单模型绑定，相关表值：

Route::patch('dashboard/product/{id}', [
    'uses' => 'Dashboard\Product\ProductController@update',
    'as' => 'dashboard.products.update'
]);

以显示形式编辑：

{{ Form::model($product, array(
                      'method' => 'PATCH', 
                      'route' => array('dashboard.products.update', $product->id),
                    )) }}
    //enter code here
{{ Form::close() }}
