Rails - オプションをDBに保存する（onchange）

Question

DBにオプションを保存しようとしています。コンソールに節約しながら はDBでこれを取得：

• 右選択した値：IDを更新する"result"=>"1"その1-4
• 右値："id"=>"4"その1-100

私はいずれかを感謝します助言や助けを借りて、カップルの時間を把握しようとしています。

しかし、まだこのエラー取得：

ROUTES

post 'update_result/:id', to: 'dashboard#update_result', as: :update_result 

CONTROLLERを

def update_result 
     @result = Bitbucket.find(params[:id]) 
     @result.update_attributes(params[:result]) 
    end 

コントローラにプライベート関数を追加することによって解決ビューで

<%= form_for(commit, url: update_result_path(commit), :method => :post, :remote => true) do |r| %> 
    <%= r.select :result, [['Waiting', 1], ['Success', 2], ['Broken - Not Submitted', 3], ['Broken - Quick Win', 4]], { selected: commit.result }, { onclick: "$(this).parent('form').submit();" } %> 
<% end %> 

DB MIGRATION

create_table :bitbuckets do |t| 
    t.string :name 
    t.text :message 
    t.text :date 
    t.datetime :remain, :null => false, :default => Time.now 
    t.integer :assignee 
    t.integer :result 

    t.timestamps null: false 
end
