私は、エラーを解決する方法がわからないよ、私は以下のようなものを試してみましたが、動作しません：

<span> 
    <%= form_for friendship, url: friendship_path(requester), method: :put do |f| %> 
    <%= f.hidden_field :user_id, value: current_user.id %> 
    <%= f.hidden_field :friend_id, value: requester.id %> 
    <%= submit_tag "Accept_test", controller: "friendships", action: "update", class: "btn btn_add_friend" %> 
    <% end %> 
</span>

更新コントローラがありますidパラメータを待っていますが、渡すパラメータはuser_idとfriend_idです。あなたは、次の

resources :friendships, only: [:create, :destroy] do 
    collection do 
    put :update 
    end 
end
