【问题描述】：

我试图将我的数据库创建到 laravel 应用程序，但收到此错误。 我正在关注这个here 教程。

我无法访问我的文章数据库，但我可以从 User.php 预定义模型访问任何内容。

路由.php 

use App\article;
/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('article', function () {
    echo article::all();
});

article.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class article extends Model
{

}

【问题讨论】：

  • 您的数据库中是否有“文章”表？
  • 当您将模型命名为“Article”并且没有覆盖 $primaryKey 和 $table 时，Eloquent 会假定该表为“articles”且主键为“id”。
  • 我在数据库中有文章表而不是文章，但它显示的文章有误

标签： php mysql laravel-5


【解决方案1】：

在您的模型“article.php”中执行此操作。 

namespace App;

use Illuminate\Database\Eloquent\Model;

class Article extends Model
{
   protected $table = 'article'; 
}

它适用于您的“文章”表。

【讨论】：

  • 但我不明白问题出在哪里？
  • 问题是，当您创建模型并且不将受保护的 $table 声明为属性时，Eloquent 即 Laravel 的 ORM 以这种方式为该模型设置 table 的默认值。如果您的模型类是“用户”，它将使用表“用户”，在您的情况下，您将其命名为“文章”，因此它会在您的数据库中查找表“文章”。希望这能回答你的问题兄弟。
