How do I call a model in Laravel 5?
提问by Avi
I'm trying to get the hang of Laravel 5 and have a question which is probably very simple to solve but I'm struggling.
我正在尝试掌握 Laravel 5 的窍门，并有一个问题可能很容易解决，但我很挣扎。
I have a controller named TestController and it resides in \app\Http\Controllers
我有一个名为 TestController 的控制器，它位于 \app\Http\Controllers
This is the controller:
这是控制器：
<?php
namespace App\Http\Controllers;
class TestController extends Controller {
public function test()
{
$diamonds = diamonds::find(1);
var_dump($diamonds);
}
}
Then I have a model I created that resides in /app:
然后我创建了一个位于 /app 中的模型：
<?php
namespace App;
class diamonds extends Model {
}
Put all other mistakes aside which I'm sure there are, my problem is that laravel throws an error:
把我确定存在的所有其他错误放在一边，我的问题是 laravel 会抛出一个错误：
FatalErrorException in TestController.php line 10: Class 'App\Http\Controllers\diamonds' not found
TestController.php 第 10 行中的 FatalErrorException: Class 'App\Http\Controllers\diamonds' not found
So, how do I get the controller to understand I'm pointing to a model and not to a controller?
那么，如何让控制器理解我指向的是模型而不是控制器？
Thanks in advance...
提前致谢...

You have to import your model in the Controller by using namespaces.
您必须使用命名空间将模型导入到控制器中。
E.g.
例如
use App\Customer;
class DashboardController extends Controller {
public function index() {
$customers = Customer::all();
return view('my/customer/template')->with('customers', $customers);
}
}
In your case, you could use the model directly App\diamonds::find(1);or import it first with use App\diamonds;and use it like you already did.
在您的情况下，您可以直接使用该模型，也可以App\diamonds::find(1);先将其导入use App\diamonds;并像之前一样使用它。
Further, it is recommended to use UpperCamelCase class names. So Diamonds instead of diamonds. You also could use dd()(dump and die) instead of var_dump to see a nicely formatted dump of your variable.
此外，建议使用 UpperCamelCase 类名。所以钻石而不是钻石。您也可以使用dd()(dump and die) 而不是 var_dump 来查看您的变量的格式良好的转储。

//Your model file
<?php
namespace App\Models;
class diamonds extends Model {
}
// And in your controller
<?php
namespace App\Http\Controllers;
use App\Models\
class TestController extends Controller {
public function test()
{
$diamonds = diamonds::find(1);
var_dump($diamonds);
}
}

Try adding the following lines above your class decleration in your controller file...
尝试在控制器文件中的类声明上方添加以下行...
use App\Diamonds;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
(this assumes your model file is called Diamonds.php)
（这假设您的模型文件被称为Diamonds.php）

Ultimately, there were a few issues here and all of you helped, however I was missing the following on the model page:
最终，这里出现了一些问题，你们所有人都提供了帮助，但是我在模型页面上遗漏了以下内容：
use Illuminate\Database\Eloquent\Model;
