Question

我希望我的rails控制器索引操作一次呈现多个输出，我的控制器：

 class Api::V1::Ola::OlaBookingsController < ApplicationController
 def index
   lat = params[:lat].to_s
   long = params[:long].to_s
   drop_lat = params[:drop_lat].to_s
   drop_lng = params[:drop_lng].to_s    
   ola_query = { 
     "pickup_lat" => lat,
     "pickup_lng" => long,
     "drop_lat" => drop_lat ,
     "drop_lng" => drop_lng
   }
   ola_body = {
     "pickup_lat" => lat,
     "pickup_lng" => long,
     "drop_lat" => drop_lat,
     "drop_lng" => drop_lng,
     "pickup_mode" => "NOW",
     "category" => "auto"
   } 
   ola_headers = {
     "Authorization" => "Bearer ", 
     "X-APP-TOKEN" => ""
   }

   @ola_products = HTTParty.get(
     "http://sandbox-t.olacabs.com/v1/products", 
     :query => ola_query,
     :headers => ola_headers
   ).parsed_response

   @ola_booking = HTTParty.post(
     "http://sandbox-t.olacabs.com/v1/bookings/create ", 
     :body => ola_body,
     :headers => ola_headers
   ).parsed_response

  render :json => @ola_booking 
  render :json => @ola_products 
  end
end

我希望两个响应都能在控制器上出现，而不会生成视图。但它给出了“多重渲染不可能”的错误，如何修复它？

Answer 1

你不能有2个渲染，你可以做的是一个接一个地组合2个对象，如

render :json => @ola_booking.to_json + @ola_products.to_json

你应该尝试一下，让我知道它是如何运作的

Answer 2

你可以试试这个。

    public TextureRegion(Texture texture)

在调用api时多次在rails控制器动作中渲染
