Question

我正在使用带角度的rails，我已经创建了一个实时搜索输入字段。我正在排除故障，为什么查询在浏览器内需要大约1.5秒，但直接从mysql控制台运行完全相同的查询时只需23毫秒。任何帮助将不胜感激。

这就是我所拥有的：

products_controller.rb

def getProducts
  @product_results=Product.searchProduct(params[:term])
  respond_to do |format|
    format.json { render json: @product_results}
  end
end

product.rb

def self.searchProduct(search)
  if search
    where('product_name LIKE :column or product_code like :column', :column => "%#{search}%")
  else
    scoped
  end
end

导致查询：

SELECT * `products` 
WHERE (product_name LIKE '%example%' or product_code like '%example%')

的routes.rb

resources :products do
  get :getProducts, :on => :collection
end

product.html：这就是魔术的用武之地。我使用了这些人开发的指令https://github.com/ghiden/angucomplete-alt

<angucomplete-alt id="ex1"
   placeholder="Search Products"
   pause="100"
   selected-object="selectedProduct"
   remote-url="products/getProducts?term="
   remote-url-data-field="products"
   title-field="product_name"
   minlength="1"
   input-class="form-control form-control-small">
 </angucomplete-alt>

这是我所注意到的。如果您在输入字段中键入内容并且查询被中断，则会重置查询。不确定这是否与它有关。视图呈现为.6秒，但ActiveRecord仍需要1秒才能完成。

控制台：

Rails和Angularjs在自动完成字段上缓慢查询结果
