2つのレコードを1つではなく作成するメソッドを作成しますか？

Question

「友達を追加」リンクをクリックすると、2つの同一のレコードが作成されます。 1つのレコードしか作成されていないはずです。私はcreateメソッドにリンクするさまざまな方法を根本的な問題として考えました。

ビュー：ユーザーが/インデックス

<ul> 
    New friend requests 
    <% @incoming.each do |user| %> 
    <% @users.each do |f| %> 
    <% if f.id == user.user.id %> 
    <li> 
    <%= f.name %> 
    <%= link_to "Accept request", friend_request_path(id: user), :method => :put %> 
    </li> 
    <% end %> 
    <% end %> 
    <% end %> 
</ul> 

<ul> 
    All users 
    <% @users.each do |user| %> 
    <% if user.id != current_user.id %> 
    <li><%= user.name %> 
    <%= link_to "Add Friend", friend_requests_path(:friend_id => user), :method => :post %></li> 
    <% end %> 
    <% end %> 

</ul>

JSは自分のアプリケーションの中に二回ロードされていました。私のapplication.jsファイルからこれらの行を削除すると、リクエストは1つしか作成されませんでした。

削除：

//= require turbolinks 
//= require rails-ujs 
//= require_tree . 

電流：

//= require jquery 
//= require jquery.turbolinks 
//= require jquery_ujs 
//= require bootstrap/dropdown
