関係メソッドは、Laravel FormBuilderの型のオブジェクトを返す必要があります

Question

私はlaravel 5.1で作業しています。 Model.phpライン2673で

LogicException：私は次のエラーを取得していますEDIT機能で 関係法は、タイプを照らし\データベースのオブジェクトを返す必要がありますが、\雄弁\リレーションズ\関係

は、ここで私のコントローラであり、機能：

public function edit(FormBuilder $formBuilder, $id) { 
    $result = News::findOrFail($id); 
    $form = $formBuilder->create('employment_bank\Forms\NewsForm', [ 
     'method' => 'PUT', 
     'model' => $result, 
     'url' => route($this->route.'update', $id) 
    ])->remove('save'); 
    return view($this->content.'edit', compact('form')); 
} 

ニュースモデル：

protected $table = 'news'; 
public static $rules = [ 
    'title' => 'required', 
]; 

protected $guarded = ['id', '_token']; 
protected $fillable = ['title', 'photo', 'status', 'summary', 'description', 'news_category_id', 'slug']; 
public $timestamps = true; 

public function news_category(){ 
    return $this->belongsTo('employment_bank\Models\NewsCategory', 'news_category_id'); 
} 

そして、形式は次のとおりです。フルで

public function buildForm(){ 

    $category = NewsCategory::lists('title', 'id')->all(); 
    $status = array(1 => "Publish",0 => "Draft"); 

    $this->add('title', 'text', [ 
     'attr' => ['required', 'maxlength' => '255', 'placeholder'=> 'News title'], 
     'wrapper' => ['class' => 'form-group'] // Shows the wrapper for each e 
    ]); 
    $this->add('photo', 'file', [ 
     'attr' => ['id' => 'photo_url', 'accept'=>'.jpg, .png', 'title'=>'Please upload a passport size photograph'], 
     'label' => 'Photo' 
    ]); 
    $this->add('news_category_id', 'select', [ 
     'choices' => $category, 
     'empty_value' => '==== Select Category ===', 
     'label' => 'Category', 
     'attr' => ['required'], 
    ]); 
    $this->add('status', 'select', [ 
     'choices' => $status, 
     'empty_value' => '==== Status ===', 
     'label' => 'status', 
     'attr' => ['required'], 
    ]); 
    $this->add('summary', 'textarea', [ 
     'attr' => ['maxlength' => '255', 'rows' => '5', 'placeholder'=> 'News summary'], 
     'wrapper' => ['class' => 'form-group'] // Shows the wrapper for each e 
     //'wrapper' => ['class' => 'form-group col-md-6'] // Shows the wrapper for each e 
    ]); 
    $this->add('description', 'textarea', [ 
     'attr' => ['rows' => '10', 'placeholder'=> 'News description'], 
     'wrapper' => ['class' => 'form-group'] // Shows the wrapper for each e 
     //'wrapper' => ['class' => 'form-group col-md-6'] // Shows the wrapper for each e 
    ]); 

    $this->add('save', 'submit', [ 
     'attr' => ['class'=>'btn btn-lg btn-primary col-md-12'] 
    ]); 

    $this->add('update', 'submit', [ 
     'attr' => ['class'=>'btn btn-lg btn-success col-md-12'] 
    ]); 
}

をしていますか？

Answer 1

NewsFormでは、2つのボタン（保存および更新）をキーワードとして扱いました。

$this->add('save', 'submit', [ 
    'attr' => ['class'=>'btn btn-lg btn-primary col-md-12'] 
]); 

$this->add('update', 'submit', [ 
    'attr' => ['class'=>'btn btn-lg btn-success col-md-12'] 
]); 

ニュースと更新ニュースには、私のために働いた更新保存に保存にボタンを変更します。

Answer 2

あなたのアプリのどこかのように、モデルインスタンス上に存在しないメソッドにアクセスしようとしています。そのため、関係を検索しています。
