Question

我是一名初级开发人员，我正在尝试将Bootstrap Toggle（http://www.bootstraptoggle.com/）集成到我的项目中。该复选框显示良好，并且似乎可以在DB中使用，但是切换未正确切换。 Iam只是尝试切换一个布尔值（is_sent）并使用ajax和remote：true技巧更新我的购买状态。这是代码：

index.html.erb

      <% @purchases.order("created_at DESC").each do |purchase| %>
      <h2>Command n°<%= purchase.id %></h2>
         <% @orders.where(id: purchase.order_id).each do |order| %>          
      <h3> <strong>Complete Information:</strong> </h3>
      <h4> Command sent ? ? </h4>

    <%= form_for purchase do |f| %>
    <%= f.check_box :is_sent, 'data-toggle' => 'toggle', 'data-onstyle' 
    => "danger", id: 'toggle1', 'data-style' => "slow",
         data: {
        remote: true,
        url: url_for(action: :update, id: purchase.id),
        method: "PATCH"
        }  %>
        <% end %>

    <script src="https://gitcdn.github.io/bootstrap- 
    toggle/2.2.2/js/bootstrap-toggle.min.js"></script>
    <link href="https://gitcdn.github.io/bootstrap- 
    toggle/2.2.2/css/bootstrap-toggle.min.css" rel="stylesheet"/>
    <script>
    $(function() {   
        $('toggle1').bootstrapToggle();
      })
    </script>

admin_purchases_controller：

  def update
     @purchase = Purchase.find(params[:id])
     status = !@purchase.is_sent
     @purchase.is_sent = status
     @purchase.save
  end

路线：

  namespace :admin do
    resources :purchases, only: [:index, :update] 
  end

现在您可以看到，当我单击切换开关时，该值已很好地保存在数据库中：

但是第一次我单击按钮时，它没有切换。之后，它的开关正确，但是值不是好的。。。

也许我必须设置动态ID，因为要进行迭代，但是在那种情况下，我不知道该怎么做..

对不起，我的英语不好，我希望有人能帮忙！预先感谢
