Laravel-找不到模型类 [英] Laravel - Model Class not found

问题描述

开始使用模型时，出现以下错误

When starting to work with models I got the following error

找不到类帖子.".

Class Post not found`.

我所做的一切:
-使用命令php artisan make:model
创建模型 -尝试使用echo Post::all()

All I did:
- Created a Model with the command php artisan make:model
- Tried to get all entries from table posts with echo Post::all()

我使用了以下代码:

router.php

Route::get('/posts', function(){
    $results = Post::all();
    return $results;
});

Post.php

<?php 
namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model {
    protected $table = 'posts';    
}

我尝试了什么
-重命名类
-转储自动加载(​​未找到Laravel 4模型类)

What I tried
- Renaming Class
- Dump-autoload (Laravel 4 Model class not found)

推荐答案

Laravel 5促进了命名空间的使用用于模型和控制器.您的模型位于App命名空间下，因此您的代码需要这样调用:

Laravel 5 promotes the use of namespaces for things like Models and Controllers. Your Model is under the App namespace, so your code needs to call it like this:

Route::get('/posts', function(){

        $results = \App\Post::all();
        return $results;
});

如评论中所述，您还可以use或将名称空间导入文件中，因此您无需引用完整路径，如下所示:

As mentioned in the comments you can also use or import a namespace in to a file so you don't need to quote the full path, like this:

use App\Post;

Route::get('/posts', function(){

        $results = Post::all();
        return $results;
});

虽然我正在对名称空间做简短的介绍，但我也可能会提到别名的功能.这样做意味着您实际上可以只在一个文件的范围内重命名您的类，如下所示:

While I'm doing a short primer on namespaces I might as well mention the ability to alias a class as well. Doing this means you can essentially rename your class just in the scope of one file, like this:

use App\Post as PostModel;

Route::get('/posts', function(){

        $results = PostModel::all();
        return $results;
});
