ユーザー認証に Devise を使用していますが、関連付けられたプロファイルをユーザーと共に破棄したいと考えています。
私の失敗した仕様は次のようになります。
it "should destroy associated profile" do
profile = @user.profile
@user.destroy
expect(profile).to be_nil
end
と
私のユーザーモデルでは:
has_one :profile, dependent: :destroy
私のプロファイルモデルでは:
belongs_to :user
コンソールでは、次のように問題を再現できます。

興味深いことに、ユーザーは実際に削除されたようです。

ActiveRecord::RecordNotFound: Couldn't find User with id=25
ここで何が起こっているのですか?
