Question

：

1) User micropost associations status feed should include the microposts of followed users 
Failure/Error: @user.feed.should include(mp3)

がmp3のように思えるがフィードに含まれていません。どのようにそれを修正するための任意のアイデア？または、コード内で起こりうるエラーを探す場所はどこですか？私はファイルをHartl's original codeと比較した。正確であるようです。

ありがとうございました。

Answer 1

はい、関係の設定に問題があるようです。 Userモデルのfollow!メソッドがこのようになっていることを確認してください。

def follow!(followed) 
    relationships.create!(:followed_id => followed.id) 
end
