Laravel 中“where 子句”中的未知列“id”，带有自定义“id”属性

Question

我在 Laravel 的用户模块中工作。

我创建了表“users”，其中包含一个名为“id_user”的增量字段。

我已覆盖模型的 $primaryKey，但它继续使用“id”默认字段进行查询。

我也试过$key，但还是一样。

我想在“users”表中将“id_user”字段更改为“id”会起作用，但我需要在表中使用自定义 id。

我在这里粘贴我的相关文件：

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);
}

/**
 * Show the form for editing the specified resource.
 *
 * @param  int  $id
 * @return Response
 */
public function edit($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.
 *
 * @param  int  $id
 * @return Response
 */
public function update($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)
{
    //
}

}

型号：User.php

use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface {

    return $this->password;
}

/**

    return $this->email;

    $rules = array(
        'user'  => 'required|min:4|max:15|unique:users',
        'password'  => 'required|min:7|confirmed',
        'email'     => 'required|email|unique:users',
        'fullname' => 'required|min:4|max:40',
        '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;
}

}

迁移

public function up()
{
    Schema::create('users', function($table)
    {
        $table->increments('id_user');
        $table->string('user');
        $table->string('password');
        $table->string('email');
        $table->string('fullname');
        $table->string('address');
        $table->string('rank');
        $table->string('avatar');
        $table->timestamps();
    });
}

'reminder' => array(

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

    'table' => 'password_reminders',

    'expire' => 60,

),

);

知道我做错了什么吗？为什么它默认查询'id'而不是我的自定义'id_user'？

谢谢！

Answer 1

我遇到了 Validator 类的问题。它没有使用我分配的 $primaryKey，因为电子邮件的规则是错误的。

这是正确的：

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

其中第三个参数 (id_user) 是用于进行查询的主键。

Answer 2

错误似乎在store 方法中。

改变：

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

收件人：

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