【问题描述】：

我正在尝试运行 php artisan migrate:fresh 来发布对我的播种机的修改。它部分工作，它删除了数据库中的所有表，但它不会重新创建它们，因为Table 'database.themes' does not exist。我在下面包含了我的Themes.php 模型、ThemesController.php 和任何其他需要Themes 的资源，希望能够理解这一点。

【问题讨论】：

通常您会分别创建（迁移）和填充（播种机）。我不记得这是否真的是一个例外，但无论哪种方式，最好将它们分开。

您是否尝试删除您的 DB::insert 语句并再次运行迁移？

如果我没记错的话，laravel 在 artisan 命令上的命令之前运行 Providers，所以它尝试在 RouteServiceProvider 上运行 $settings = Themes::get(); 并失败，因此出现错误。对于临时修复，请删除该代码，然后运行 ​​migrate 命令。

@MathiasHillmann 请把你的答案写在下面，我会标记它，另外，这个服务提供商是完整功能所必需的，我打算让这个 laravel 包可用，有没有另一种方法来制作其服务提供商之外的路由工作？例如，在控制器中？

【参考方案1】：

对于更永久的修复，您可以在运行查询之前检查模型/表是否存在：

    public function boot()
    
        if($settings = Themes::get())
            $this->configureRateLimiting();

            $this->routes(function () use ($settings) 
                Route::prefix('api')
                ->middleware('api')
                ->namespace($this->namespace)
                    ->group(base_path('routes\api.php'));

                Route::middleware('web')
                ->namespace($this->namespace)
                    ->group(base_path('routes\web.php'));


                foreach ($settings as $key => $setting) 
                    Route::middleware('web')
                    ->group(base_path('resources/views/themes/' . $setting->theme_slug . '/route.php'));
                
            );
