提问by Guns
I am a newbie to Laravel. Please excuse me if this question sounds kiddish.
我是 Laravel 的新手。如果这个问题听起来很幼稚，请原谅。
I have a model
我有一个模型
class Config extends Eloquent {
public static $table = 'configs';
}
and the controller goes as
和控制器去
class UserController extends BaseController {
Public function getIndex ()
{
$config_items = Config::all ();
var_dump ( $config_items );
return View::make ( 'user.userindex' )
-> with ( 'title', 'User Page' );
}
}
But when i try to access the Config model, i am getting the error:
但是当我尝试访问 Config 模型时，出现错误：
Symfony \ Component \ Debug \ Exception \ FatalErrorException Call to undefined method Illuminate\Config\Repository::all()
Symfony \ Component \ Debug \ Exception \ FatalErrorException 调用未定义的方法 Illuminate\Config\Repository::all()
Please help!
请帮忙！

我知道这个问题可以帮助像我和我的同事一样的许多 Laravel 4 新手，所以请帮忙！

As the commenter pointed out, Configis actually a class that's already defined / used.
正如评论者指出的，Config实际上是一个已经定义/使用的类。
You have two options:
您有两个选择：
Option 1:
选项1：
Namespace your Configmodel:
命名空间您的Config模型：
<?php namespace My\Models;
use Illuminate\Database\Eloquent\Model;
class Config extends Model { ... }
Then in your controller:
然后在您的控制器中：
$config_items = My\Models\Config::all();
Note:If you go with option 1 (I suggest you do), you'll need to set up autoloading for your namespaced library. See this blog article on setting up your own Laravel library with autoloading.
注意：如果您选择选项 1（我建议您这样做），您需要为命名空间库设置自动加载。请参阅这篇关于使用自动加载设置您自己的 Laravel 库的博客文章。
Option 2:
选项 2：
Don't use Configas a model name:
不要Config用作模型名称：
<?php
class Configuration extends Eloquent { ... }
Then in your controller:
然后在您的控制器中：
$config_items = Configuration::all();
Hope that helps!
希望有帮助！

I think Config is a reserved keyword used by laravel to manage config files, so please try changing the model name to something else
我认为 Config 是 laravel 用来管理配置文件的保留关键字，所以请尝试将模型名称更改为其他名称
