My index.html file contains a Google API map implementation.

I am looking to use the variable "pos" in my Ruby on Rails controller, specifically in the products controller.
require 'rubygems'
require 'httparty'
class ProductsController < ApplicationController
def index
@results = HTTParty.get("https://api.uber.com /v1/products?server_token=xyz&latitude=37.7759792&longitude=-122.41823").parsed_response
respond_to do |format|
format.json { render :json => JSON.parse(@results) }
format.html { render "index.html.erb" }
end
end
end
I want to dynamically pass latitude and longitude values in the API URL instead of hardcoding them manually. Any suggestions on how I can achieve this?
