問題描述

從 Laravel 4.2 更新到 5.0 后，我幾乎在應用程序的每個頁面中都收到以下消息:

After updating from Laravel 4.2 to 5.0, I am getting the following message in almost every page of my application:

UrlGenerator.php 第 561 行中的 InvalidArgumentException:未定義 Action ArticlesController@create.

在我的 routes.php 文件中，我有:

In my routes.php file I have:

Route::get('articles/create', ['as' => 'articles.create', 'uses' => 'ArticlesController@create']);
Route::post('articles/create', ['as' => 'articles.create.handle', 'uses' => 'ArticlesController@handleCreate']);

在我的控制器中:

class ArticlesController extends Controller {

    public function create()
    {
        $input=null;
        if (Input::old()) {
            $input = Input::old();
        }
        $tagsJson = Tag::all()->toJson();
        $categories = ArticleCategory::all();
        return View::make('admin.articles.create', compact(array('tagsJson', 'categories', 'input')));
    }

    public function handleCreate()
    {
        $input = Input::all();

        if ($input['op']=="preview") {
            return redirect()->action('ArticlesController@create')->withInput();
        } else if ($input['op']=="post") {
            //
        }

    }
}

我得到的錯誤來自這一行:

The error I get comes from this line:

return redirect()->action('ArticlesController@create')->withInput();

有什么幫助嗎?謝謝，伊利亞斯

Any help? Thanks, Ilias

推薦答案

您收到此錯誤是因為 Laravel 5 默認使用命名空間.官方 Laravel 5 升級指南對遷移控制器做了以下說明:

You are getting this error because Laravel 5 uses namespacing by default. The official Laravel 5 upgrade guide says the following about migrating your controllers:

由于我們不會在本指南中遷移到完整命名空間，請將 app/Http/Controllers 目錄添加到您的 composer.json 文件的 classmap 指令中.接下來，您可以從抽象的 app/Http/Controllers/Controller.php 基類中刪除命名空間.驗證您遷移的控制器是否擴展了這個基類.

Since we are not going to migrate to full namespacing in this guide, add the app/Http/Controllers directory to the classmap directive of your composer.json file. Next, you can remove the namespace from the abstract app/Http/Controllers/Controller.php base class. Verify that your migrated controllers are extending this base class.

在您的 app/Providers/RouteServiceProvider.php 文件中，將命名空間屬性設置為 null.

In your app/Providers/RouteServiceProvider.php file, set the namespace property to null.

在控制器"下此處列出.

最后一行可能會解決您的問題.

The last line is probably the one that will solve your issue.
