与（）一起使用时的Laravel 5 BadMethodCallException

在过去的5个小时里，我一直在努力解决这个问题，这让我发疯

首先，这是我的代码

有一个产品控制器

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Redirect;
use Illuminate\Support\Facades\Session;

use Cviebrock\EloquentSluggable\SluggableInterface;
use Cviebrock\EloquentSluggable\SluggableTrait;

use Illuminate\Http\Request;

use App\Product;

class ProductController extends Controller {

    protected $product;

    public function __construct(Product $product)
    {
        $this->product = $product;
        $this->middleware('auth', ['except' => ['index','show']]); 
    }

产品型号：

<?php namespace  App;

use Illuminate\Database\Eloquent\Model;
use Cviebrock\EloquentSluggable\SluggableInterface;
use Cviebrock\EloquentSluggable\SluggableTrait;

class Product extends Model implements SluggableInterface {

    use SluggableTrait;

    protected $guarded = array();


    protected $sluggable = array(
        'build_from' => 'title',
        'save_to'    => 'slug',
    );


    public static $rules = array(
        'type'         => 'required',
        'price'        => 'required',
        'title'        => 'required' 
    );

    protected $fillable = [
        'shorturl',
        'url',
        'type',
        'title',
        'slug',
        'overview',
        'price',
        'availability'
    ];



    /**
     * through product_tags pivot table
     * @return [type] [description]
     */
    public function tags()
    {
        return $this->hasMany('App\Tag');
    }



    public function images()
    {
        return $this->hasMany('App\Image');
    }



}

我得到了我要找的唱片。如果我使用

$products           = $this->product->with('images' )->find($id);

然后我得到以下错误

BadMethodCallException in Builder.php line 1990:
Call to undefined method Illuminate\Database\Query\Builder::images()

前几行是：

in Builder.php line 1990
at Builder->__call('images', array())
at Builder->images()
at call_user_func_array(array(object(Builder), 'images'), array()) in Builder.php line 933
at Builder->__call('images', array())

at Product->images() in Builder.php line 451
at Builder->Illuminate\Database\Eloquent\{closure}()
at call_user_func(object(Closure)) in Relation.php line 158

如果你愿意的话，我可以发布其余的内容，但我认为我的错误是我遗漏的一个非常基本的东西

这是完整的堆栈跟踪

如果仔细检查堆栈跟踪

Model->\uuu调用（'images'，array（））

会清楚地看到它，这是因为它没有从

Product

中调用

（

方法）（因为它是静态的）

但是，您应该能够做到以下几点：

$products = $this->product->newQuery()->with('images')->find(1);

---

您发布的图像模型有一个类名Product

如果是您的实际代码，则：

public function images()
{
    return $this->hasMany('App\Image');
}

---

此关系中使用的App\Image类不存在。

我认为这不是问题所在。在帖子中添加了完整的堆栈跟踪。您确定在

产品

类中有

公共函数图像（）{}

（我在您发布的代码中没有看到，但我假设这只是一个输入错误）。如果是这种情况，则实际问题不是不存在的

图像
类，而是错误的
产品
类被注入控制器谢谢您的用户3384745。这总是小事：-（我对此感到非常尴尬
