提问by Jonathan Solorzano
Is there a command to safely delete a model in Laravel 5? To create a model we use
Laravel 5 中是否有安全删除模型的命令？要创建我们使用的模型

And that will create a model under appfolder, and also a migration in database/migrations
这将在app文件夹下创建一个模型，并在database/migrations
But what I can't find is how to delete a model...
但我找不到的是如何删除模型...

Deleting a model: just delete the model under App/or whatever other folder.
删除模型：只需删除App/或任何其他文件夹下的模型。
Deleting a migration: if you have migrated it (meaning the database has suffered changes) you have two choices:
删除迁移：如果您已经迁移了它（意味着数据库发生了变化），您有两种选择：
The "project starting"/ugly way is to migrate:rollbackuntil the migration is undone (if it was the last migration you did, one rollback is enough, if not, you're gonna have to rollback a couple of times) then delete the migration file (the one inside the database/migrationsfolder. Important thing here: the migration's class will still be autoloader by composer. So you have to remove the migration class loading from vendor/composer/autoload_classmap.php. Maybe composer dumpautoloadwill work, it didn't for me though. If you have no important data in the DB and you can wipe it, delete the migration file, composer dumpautoloadthen run php artisan migrate:refresh. This will rollback every migration then migrate everything back in.
“项目启动”/丑陋的方法是migrate:rollback直到迁移完成（如果这是您所做的最后一次迁移，则回滚一次就足够了，否则，您将不得不回滚几次）然后删除迁移文件（database/migrations文件夹内的那个。重要的是：迁移的类仍将是作曲家的自动加载器。因此，您必须从 中删除迁移类加载vendor/composer/autoload_classmap.php。也许composer dumpautoload会起作用，但对我来说却没有。如果您没有重要数据在数据库中，您可以擦除它，删除迁移文件，composer dumpautoload然后运行php artisan migrate:refresh。这将回滚每个迁移，然后将所有内容迁移回。
The "this is in production and I messed up" way: create another migration where the up method is dropping the first migration's table, down is creating it (basically the up method from the first migration). Leave the two migration files in there, don't remove them.
“这是在生产中，我搞砸了”的方式：创建另一个迁移，其中 up 方法删除第一个迁移的表，down 正在创建它（基本上是第一次迁移的 up 方法）。将两个迁移文件留在那里，不要删除它们。
If you haven't migrated it, just delete the migration file, composer dumpautoloadand if you have some class/file not founderror, check if vendor/composer/autoload_classmap.phphas the class of the file you just removed and delete the row there.
如果您还没有迁移它，只需删除迁移文件，composer dumpautoload如果您有class/file not found错误，请检查是否vendor/composer/autoload_classmap.php有您刚刚删除的文件的类并删除那里的行。

You can delete model in App folder if you see this error (Model Already Exists!)
如果您看到此错误，您可以删除 App 文件夹中的模型（模型已存在！）

search in vendor/composer/autoload_classmap.php Ctrl+F write modelname delete allow edit this folder and delete model path
在 vendor/composer/autoload_classmap.php 中搜索 Ctrl+F write modelname delete 允许编辑此文件夹并删除模型路径

The problem can also arise when your database name is different from the one defined in .envfile.
当您的数据库名称与.env文件中定义的名称不同时，也会出现此问题。
DB_DATABASE=laravel
By default, database structure in .envsets database name as laravel. You can replace laravelwith the name of your database.
默认情况下，数据库结构中的.env数据库名称设置为 laravel。您可以替换laravel为您的数据库的名称。

<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
class RemoveController extends Command

if(file_exists($controllerPath)){
unlink($controllerPath);
$this->line('Controller removed successfully.');
}else{

No command, just do it manually and its safe
无需命令，只需手动操作，安全无虞
- Delete the model first (if you don't) need the model any longer
- Delete the migration from
...database/migrationsfolder - If you have already migrated i.e if you have already run
php artisan migrate, log into your phpmyadmin or SQL(whichever the case is) and in your database, delete the table created by the migration - Still within your database, in the migrations folder, locate the row with that migration file name and delete the row.
- 先删除模型（如果你不需要）不再需要模型
- 从
...database/migrations文件夹中删除迁移 - 如果您已经迁移，即如果您已经运行
php artisan migrate，请登录您的 phpmyadmin 或 SQL（无论哪种情况）并在您的数据库中，删除迁移创建的表 - 仍在您的数据库中的迁移文件夹中，找到具有该迁移文件名的行并删除该行。
Works for me, hope it helps!
对我有用，希望能帮到你！
