Skyscanner Flight search API with Ruby on rails6 - ruby-on-rails

Question

Hi i'm working on flight ticket website(search cheap flight ticket),using Skyscanner Flight API. Basically i copied this API tutorial to implement flight search function. However it only shows blank result in search.html.erb. In tutorial's form page you only fill out country name in form using different API. I'm stuck now and wonder how to implement search action & find_ticket action to take several parameter from index page's form and shows result properly.
Environment Rails:6.02 Ruby:2.65 RapidApi:skyscannerFlightSearch(i'm using RakutenRapidAPI)
Routes.rb
Rails.application.routes.draw do
root to: 'travel#index'
get '/search' => 'travel#search'
resources :messages
end
travel_controller.rb
class TravelController < ApplicationController
def index
end
def search
tickets = find_ticket(params[:country])
unless tickets
flash.now[:alert] = 'ticket not found'
return render action: :index
end
#ticket = tickets.first
end
private
def find_ticket(name)
request_api(
"https://skyscanner-skyscanner-flight-search-v1.p.rapidapi.com/apiservices/browsequotes/v1.0/#{URI.encode(name)}"
)
end
def request_api(url)
response = Excon.get(
url,
headers: {
'X-RapidAPI-Host' => URI.parse(url).host,
'X-RapidAPI-Key' => Rails.application.credentials.rapid[:XXXX_key]
}
)
return nil if response.status != 200
JSON.parse(response.body)
end
end
