ruby on rails - Displaying data when searching through external API -

so, trying search through external api (nutrionix) , having trouble figuring out how display results.

i have form searching

<form action = "/foods" method = "get">   <div class = "field">     <input type = "text" name = "searched_value" alt = "search foods" />   </div>   <div class = "btn">     <input type = "submit" name ="btn" value = "search foods">   </div> </form> 

then have in foodscontroller:

class foodscontroller < applicationcontroller   require 'faraday'   require 'json'    def search     @searched_food = params[:searched_value].split(" ").join("%20")     @response_body = faraday.get("https://api.nutritionix.com/v1_1/search/#{@searched_value}?format=json?fields=item_name%2citem_id%2cbrand_name%2cnf_calories%2cnf_total_fat&appid=[myappid]&appkey=[myappkey]").body     @parsed_response = json.load(@response_body)   end end 

my relevant routes are:

rails.application.routes.draw   'food_form'  =>   'foods#food_form'   'foods'       => 'foods#foods'   'search'     =>     'foods#search' end 

it goes page links "add foods" page i'm trying stuff show have:

<div class = "description">   <%= link_to "add foods", food_form_path %>   <%= @parsed_response%>   <%= @response_body%>   <%= @searched_food %> </div> 

i nothing results link form appears. however, when put controller info on html page can see results , if go nutrionix link myself, results.

help appreciated. :)

the search form isn't hitting action supposed because has action = "/foods" should action = "/foods/search". changing should solve problem.

<form action = "/foods/search" method = "get">   <div class = "field">     <input type = "text" name = "searched_value" alt = "search foods" />   </div>   <div class = "btn">     <input type = "submit" name ="btn" value = "search foods">   </div> </form>
