laravel-4 - BindingResolutionException 目标 [Illuminate\Database\Eloquent\Model] 不可实例化

Question

我遇到以下错误。这不是关于接口(interface)错误，而是关于模型错误。我不知道下面的代码有什么问题。

Illuminate \ Container \ BindingResolutionException

Target [Illuminate\Database\Eloquent\Model] is not instantiable.

我不知道如何处理这个问题。

我有公司模型。

use Illuminate\Database\Eloquent\Model;

class Company extends Eloquent{
   protected $softDelete = true;
   protected $table = "companies";
   protected $fillable = [];
   protected $guarded = [];
}

那是companyrepositoryinterface

namespace ohbt\Repositories;
 interface CompanyRepositoryInterface{
 }

那是companyrepository

namespace ohbt\Repositories\Eloquents;

use Company;
use Illuminate\Database\Eloquent\Model;
use ohnt\Services\Validator\CompanyValidator as Validator;
use ohbt\Repositories\CompanyRepositoryInterface as CompanyRepositoryInterface;

class CompanyRepository extends AbstractRepository implements CompanyRepositoryInterface{

   protected $company;
   protected $validator;

    public function __constructor(Model $company, Validator $validator){
        $this->company = $company;
        parent::__construct($this->company);
        $this->validator = $validator;
    }

    public function create(array $attributes){
    if($this->validator->isValid($attributes)){
        $this->company->create($attributes);
        return true;
    }
    return false;
    }

    public function getMessages(){
       return $this->validator->getMessages();
    }
}

并且我的 repositoryservices provider 已经添加到 app/config/app.php

namespace ohbt\Repositories;
 use Illuminate\Support\ServiceProvider;

class RepositoriesServiceProvider extends ServiceProvider {

protected $defer = false;

public function boot()
{
    //
}

public function register()
{
    $this->app->bind('VehicleRepositoryInterface', 'ohbt\Repositories\Eloquents\VehicleRepository');

    $this->app->bind('UserRepositoryInterface', 'ohbt\Repositories\Eloquents\UserRepository');

    $this->app->bind('CompanyRepositoryInterface', 'ohbt\Repositories\Eloquents\CompanyRepository');
}

public function provides()
{
    return array();
}

}

非常感谢任何建议和帮助。感谢进阶。

实际上，我认为这不是模型实例化问题的合适或好的解决方案。但它解决了我最近的问题。

我在 RepossitoryServiceProvider 中描述了具体的文件和模型。但是当这个有问题时其他绑定(bind)工作没有意义。

这是我的解决方案

 use \Company;   //Company Model added 
 use Illuminate\Database\Eloquent\Model;
 use Illuminate\Support\ServiceProvider;
 use ohbt\Repositories\Eloquents\CompanyRepository;  //Company Repository added.

class RepositoriesServiceProvider extends ServiceProvider {

protected $defer = false;

public function boot()
{
    //
}

public function register()
{
    $this->app->bind('ohbt\Repositories\BaseRepositoryInterface', 'ohbt\Repositories\Eloquents\AbstractRepository');

    $this->app->bind('VehicleRepositoryInterface', 'ohbt\Repositories\Eloquents\VehicleRepository');

    $this->app->bind('UserRepositoryInterface', 'ohbt\Repositories\Eloquents\UserRepository');

    $this->app->bind('GuestRepositoryInterface', 'ohbt\Repositories\Eloquents\GuestRepository');

     /**
      * Comment out the previous binding function. 
      * $this->app->bind('CompanyRepositoryInterface',
      * 'ohbt\Repositories\Eloquents\CompanyRepository');
      * directly return Repository Object rather than directory of Repository of Model
      **/
    $this->app->bind('CompanyRepositoryInterface', function()
    {
        return new CompanyRepository( new Company );
    });
}

public function provides()
{
    return array();
}

}

在这种情况下，我们必须声明所有模型和存储库文件以与 IoC 绑定(bind)。那不是一个好主意。因此，非常欢迎高级解决方案或更好的答案。
