帶有自定義「id」屬性的Laravel的'where子句'中的未知列'id'

Question

Im在Laravel的用戶模塊中工作。

我已經創建了名爲'id_user'的增量字段的表'用戶'。

我已經覆蓋了模型的$primaryKey，但它繼續使用'id'默認字段進行查詢。

我也試過$key，但它是一樣的。

我想在我的表'用戶'中通過'id'更改我的'id_user'字段可以工作，但我需要在我的表中使用自定義ID。

在這裏，我貼我的相關文件：

控制器：UsersController.php

class Admin_UsersController extends \BaseController { 

/** 
* Display a listing of the resource. 
* 
* @return Response 
*/ 
//GET llama a index, POST llama a store 
public function index() 
{ 
    $users = User::paginate(); 
    //dd($users); //dump de $users 
    return View::make('admin/users/list')->with('users', $users); 
    } 


/** 
* Show the form for creating a new resource. 
* 
* @return Response 
*/ 
public function create() 
{ 
    $user = new User; 
    return View::make('admin/users/form')->with('user', $user);   
} 

/** 
* Store a newly created resource in storage. 
* 
* @return Response 
*/ 
public function store() 
{ 
    $user = new User; 
    $data = Input::all(); 
    if ($user->isValid($data)) { 
     $user->fill($data); 
     $user->save(); 
     return Redirect::route('admin.users.show', array($user->id)); 
    }else{ 
     return Redirect::route('admin.users.create')->withInput()->withErrors($user->errors); 
    } 
} 

/** 
* Display the specified resource. 
* 
* @param int $id 
* @return Response 
*/ 
public function show($id) 
{ 
    $user = User::find($id); 
    if (is_null($user)) 
    { 
     App::abort(404); 
    } 

    return View::make('admin/users/profile')->with('user', $user); 
} 

/**

*

* @return Response 
*/ 
public function edit($id) 
{ 
    $user = User::find($id); 
    if (is_null ($user)) 
    { 
    App::abort(404); 
    } 

    return View::make('admin/users/form')->with('user', $user); 

} 

/** 
* Update the specified resource in storage.

public function update($id) 
{ 

    $user = User::find($id); 

    if (is_null ($user)) 
    { 
     App::abort(404); 
    } 

    $data = Input::all(); 


    if ($user->isValid($data)) 
    { 
     $user->fill($data); 
     $user->save(); 
     return Redirect::route('admin.users.show', array($user->id_user)); 
    } 
    else 
    { 
     return Redirect::route('admin.users.edit', $user->id_user)->withInput()->withErrors($user->errors); 
    } 
} 

/** 
* Remove the specified resource from storage. 
* 
* @param int $id 
* @return Response 
*/ 
public function destroy($id) 
{ 
    // 
} 

}

型號：user.php的

     'address' => 'required|min:8', 
     'rank' => 'required' 
    ); 

    // Si el usuario existe: 
    if ($this->exists) 
    { 
     $rules['email'] .= ',email,' . $this->id_user; 
     $rules['user'] .= ',user,' . $this->id_user; 
    } 
    else 
    { 
     $rules['password'] .= '|required'; 
    } 

    $validator = Validator::make($data, $rules); 

    if ($validator->passes()) 
    { 
     return true; 
    } 

    $this->errors = $validator->errors(); 

    return false; 
} 

}

'reminder' => array(

    'email' => 'emails.auth.reminder', 

    'table' => 'password_reminders', 

    'expire' => 60, 

), 

); 

任何想法，我做錯了嗎？爲什麼它默認使用'id'而不是我自定義的'id_user'來查詢？

謝謝！

Answer 1

我曾與Validator類的問題。它沒有使用我分配的$ primaryKey，因爲電子郵件的規則是錯誤的。

這是正確的：

$rules['email'] .= ',' . $this->id_user . ',id_user'; 

其中第三個參數（id_user）是主鍵，以便使查詢使用。

Answer 2

錯誤似乎在store方法。

更改：

return Redirect::route('admin.users.show', array($user->id)); 

要：

return Redirect::route('admin.users.show', array($user->id_user));
