Michael Hartl の rails チュートリアルを読んでいて、10.1.4 章で仕様検証エラーが表示されますが、指示に従っていると思います。
私はRailsの初心者ですが、次のコードは新しいマイクロポストを作成して既存のユーザーに割り当てることになっていますが、Factory Girlはすでに存在するユーザーを作成しようとしているようです:
FactoryGirl.create(:マイクロポスト、ユーザー: @user、created_at: 1.hour.ago)
エラーを修正する方法を知っている人はいますか？
エラー
1) ユーザー マイクロポストの関連付けには、正しいマイクロポストが正しい順序で配置されている必要があります。撮影 # ./spec/models/user_spec.rb:159
2) ユーザー マイクロポストの関連付けは、関連付けられたマイクロポストを破棄する必要があります 失敗/エラー: FactoryGirl.create(:micropost, ユーザー: @user, created_at: 1.hour.ago) ActiveRecord::RecordInvalid: 検証に失敗しました: ユーザーは既に取得されています # ./spec /models/user_spec.rb:159
