たぶん週刊「今週の進捗」

1週間に勉強したことや実装したことをネタに、週に1回(主に土日に)更新していく予定です。「多分」なので、臨時休刊があってもご海容ください。

Laravel デバッグメモ

Laravel

Laravel の勉強をしていたら、いくつか解消に手こずるバグがあったので、解決方法をメモ。

Session is missing expected key [errors].

テストを実行したら以下のようなエラーが出た。

テスト

public function test_status_should_be_within_defined_numbers()
{
    $this->seed('TasksTableSeeder');
    $response = $this->post('/folders/1/tasks/1/edit', [
        'title'    => 'Sample task',
        'due_date' => Carbon::today()->format('Y/m/d'),
        'status'   => 999,
    ]);
    $response->assertSessionHasErrors([
        'status' => '状態 には 未着手、着手中、完了 のいずれかを指定してくださ>い。',
    ]);
}

結果

Feature\Task
 ? Status should be within defined numbers
   x
   x Session is missing expected key [errors].
   x Failed asserting that false is true.
   x
   x /home/vagrant/code/sample/vendor/laravel/framework/src/Illuminate/Foundation/Testing/TestResponse.php:850
   x /home/vagrant/code/sample/vendor/laravel/framework/src/Illuminate/Foundation/Testing/TestResponse.php:888
   x /home/vagrant/code/sample/tests/Feature/TaskTest.php:85
   x

エラーメッセージを見ても原因がわからない…
いろいろとぐぐってみたら、以下の記事が参考になりそうでした。

public-constructor.com

対象のテストに $this->withoutExceptionHandling(); を挿入すると、エラーメッセージが見やすくなる、かも…思ってやってみたら、
エラーの一番大きな原因は作った FormRequest クラスのサブクラスを Controller で use していないことでした。

ErrorException thrown with message "Undefined offset: 1"

RegisterController でユーザ登録ページを作成して、
ブラウザから showRegisterForm にルーティングされているアドレスにアクセスしたら、エラー画面が出た。

どれも自分が触ってないファイルだから原因がわからない…

本来描画されるであろうテンプレート auth/register.blade.php を見てみたら、
foreach 文を @foreach($errors->all(() as $message) と typo していた。

ここを修正しておしまい。

メモ

他、役立ちそうなデバッグ方法
