包含多个类的 Laravel 模型 [英] Laravel model containing multiple classes

问题描述

我是 laravel 的新手，来自 Codeigntier.我试图掌握 Laravel 使用的模型/类/雄辩的约定.我知道我可以在我的数据库中创建一个名为类别"的表.然后我可以在我的模型文件夹中创建一个名为 category.php 的文件，其中只包含以下代码:

I'm new to laravel, coming from Codeigntier. I am trying to get to grips with the model/classes/eloquent convention that Laravel uses. I know that I can make a table in my database called, say, "categories". Then I can make a file in my models folder called category.php containing just the following code:

Class Category extends Eloquent { }

它会自动连接带有复数版本名称(类别")的表名，并让我可以访问我的控制器中的所有 Eloquent 命令，例如 Category::All();

which automatically connects with the table name with the plural version of the name ("categories") and gives me access to all the Eloquent commands in my controller like Category::All();

以下是我不明白的:我是否需要为数据库中的每个表创建一个新模型?在这种情况下，我的模型文件夹中会出现一堆文件，名称如 resource1.php、resource2.php 等，每个文件都包含与上面相同的代码(替换类的名称).

Here's what I don't get: Do I need to make a new model for every table in my database? In that case I will end up with a bunch of files in my models folder with names like resource1.php, resource2.php, etc, each just containing the same code as above (replacing the name of the class).

我不能只创建一个模型，例如database_handler.php"，然后将所有这些类放在同一个地方吗?

Can't I just make one model called, say, "database_handler.php" and then just put all these classes into it in the same place?

推荐答案

是的，您可以创建一个 database_handler.php 文件并执行以下操作:

Yes, you can create a database_handler.php file and do:

<?php

    Class Category extends Eloquent { }
    Class Post extends Eloquent { }
    Class Client extends Eloquent { }

您可以做任何 PHP 让您做的事情，将许多类添加到单个 .php 文件是您可以做的事情.但这不是一个好的做法，Laravel 就是要使用最好的开发应用程序.

You can do whatever PHP let's you do, and add many classes to a single .php file is something you can do. But this is not a good practice and Laravel is all about developing application using the best ones.

要自动加载此文件，您可以执行以下操作之一:

To load this file automatically, you can do one of many things:

1) 将此文件添加到您的 app/models 文件夹中.

1) Add this file to your app/models folder.

2) 在您的 composer.json 中为其添加一个条目:

2) Add an entry for it on your composer.json:

"autoload": {
    "files": [
        "app/database_handler.php"
    ]
},

然后你将不得不

composer dump-autoload -o

3) 为其创建一个不同的文件夹并将其添加到 composer json 自动加载部分.

3) Create a different folder for it and also add it to composer json autoload section.

你选择，Laravel 会让你自由地做任何你想做的事情.

You choose, Laravel will let you free to do whatever you want.
