'id' = testuserで投稿を見つけることができません

Question

投稿を削除すると、「ID '= testuser」の投稿を見つけることができませんでした。私はこれがルーティングエラーだと思うので、実行されているIDはPostであり、Userではないはずです。私はそれを解決することはできません。投稿を作成することはできますが、同じ理由で削除や編集はできません。

必要に応じてさらに詳しい情報を提供できます。

def set_post 
@work = Work.find(params[:id])

にpostインスタンスを渡すことならあなたは、削除

<%= link_to('Delete', post_path, :method => :delete) %> 

のリンクにIDまたはインスタンスを渡しませんでした投稿を見つけるためにリンクを削除する

<%= link_to('Delete', post_path(post), :method => :delete) %> 

または

<%= link_to('Delete', post_path(post.id), :method => :delete) %>
