Railsチュートリアル 第10章 リスト10.23にてテストが通りません

Question

2人目のユーザーarcherをtest/fixtures/users.ymlに追加すると２つ目のようなエラーが出てしまいます。サイト自体は動くのですが、なぜこのようなエラーが出てしまうのかが気になります。またこのエラーは今後railsチュートリアルを進めていく上で邪魔になってこないか心配です。どなたかご教授していただけると幸いです。

test/fixtures/users.yml

michael:
  name: Michael Example
  email: [e-mail]
  password_digest: <%= User.digest('password') %>

archer:
  name: Sterling Archer
  email: [e-mail]
  password_digest: <%= User.digest('password') %>

rails test後の内容　本来ならerrorなく進めることができるところらしい

rails db:migrate:resetをしてもともと登録してあった自分の名前、メールアドレスを消した。

Answer 1

初めまして。
自分も同じエラーで悩みましたが、下記の内容で解決できました。

users.ymlファイルで追加したarcher:〜の部分で、
下記の様に「archer:」の先頭にTABが入っていないでしょうか？

michael:
  name: Michael Example
  email: [e-mail]
  password_digest: <%= User.digest('password') %>
  
  archer:
  name: Sterling Archer
  email: [e-mail]
  password_digest: <%= User.digest('password') %>

「archer:」の先頭にTABを削除すれば大丈夫だと思います。

michael:
  name: Michael Example
  email: [e-mail]
  password_digest: <%= User.digest('password') %>
  
archer:
  name: Sterling Archer
  email: [e-mail]
  password_digest: <%= User.digest('password') %>
