從下拉列表中選擇值的更改提交Rails

Question

我有一個Rails應用程序，其中包含列表中的潛在客戶。在其中一個列中，我在下拉菜單中顯示潛在客戶的狀態。我想要啓用更改此下拉列表中選定值的潛在客戶狀態。

這是我的嘗試：

的代碼顯示在表格單元格的形式：

 <% @leads.each do |lead| %> 
    <tr> 
    <td><%= lead.id %></td> 
<td><%= form_for(lead,:url => 'update_lead_status') do |f| %> 
       <div class="field"> 
       <%= f.select :status, ["to_call","called","confirmed","lite"], :selected => lead.status, onchange: "this.form.submit();" %> 
       </div> 
      <% end %> 
     </td> 

我update_lead_status方法導致控制器：

#PUT 
    def update_lead_status 
    @lead = Lead.find(params[:id]) 
    respond_to do |format| 
     # format.js 
     if @lead.update_attributes(params[:lead]) 
     format.html { redirect_to leads_url, notice: 'Lead was successfully updated.' } 
     format.json { head :no_content } 
     else 
     format.html { render action: "edit" } 
     format.json { render json: @lead.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

而且我想要的提交成爲Ajax風格而不會讓人耳目一新。

套裝形式ID，然後提交表單

<%= form_for(lead,:url => 'update_lead_status',:html=>{:id=>'lead_form'}) do |f| %> 

<%= f.select :status, ["to_call","called","confirmed","lite"], :selected => lead.status, onchange: "$('#lead_form').submit();" %> 
<% end %>
