Laravel模型包含多个类 [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.我知道我可以在数据库中创建一个名为类别"的表.然后，我可以在模型文件夹中创建一个名为category.php的文件，其中仅包含以下代码:

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 { }

会自动使用名称的复数形式(类别")与表名连接，并允许我访问控制器中所有的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();

这是我不明白的:我是否需要为数据库中的每个表创建一个新模型?在那种情况下，我最终将在我的models文件夹中得到一堆文件，它们的名称类似于resource1.php，resource2.php等，每个文件都包含与上述相同的代码(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).

我不能只创建一个名为"database_handler.php"的模型，然后将所有这些类放在同一位置吗?

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 { }

您可以执行PHP所能做的任何事情，并且可以将许多类添加到单个.php文件中.但这不是一个好习惯，Laravel只是使用最好的应用程序来开发应用程序.

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，您可以执行以下其中一项操作:

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.

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"
    ]
},

然后您将不得不

composer dump-autoload -o

3)为此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.

您选择，Laravel将让您自由地做任何您想做的事.

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