Relationship-Methode muss ein Objekt vom Typ in Laravel FormBuilder

Question

zurückgeben Ich arbeite mit Laravel 5.1. Ich erhalte den folgenden Fehler in EDIT Funktion:

LogicException in Model.php Linie 2673: Relationship-Methode muss ein Objekt vom Typ Illuminate \ Database \ Eloquent \ Relations zurückzukehren \ Relation

hier ist mein Controller Funktion:

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')); 
} 

Nachrichten Modell:

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'); 
} 

Und die Form ist:

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'] 
    ]); 
}

Was mache ich falsch?

Answer 1

In NewsForm zwei Taste (Speichern und Update) wurde als ein Schlüsselwort behandelt.

$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'] 
]); 

Ändern der Schaltfläche speichern zu speichern Nachrichten und Update zu Update News für mich gearbeitet.

Answer 2

Es scheint so, als ob Sie irgendwo in Ihrer App versuchen, auf eine nicht existierende Methode in einer Modellinstanz zuzugreifen. Deshalb sucht sie nach einer Relation.

Können Sie die vollständige Stack-Ablaufverfolgung des Fehlers buchen?
