Displaying GET request from HTTparty on view

I currently have a simple ruby file named example.rb. How can I make a view that allows a user to submit information into a form and then have the information from the GET request returned to them? I understand how to use these requests from the console, but not from the front-end.

Resources on this topic would also be greatly appreciated.

require 'rubygems'
require 'httparty'

class StackExchange
  include HTTParty
  base_uri 'api.stackexchange.com'

  def initialize(service, page)
    @options = {query: {site: service}}

  def questions
    self.class.get('/2.2/questions', @options)

  def users
    self.class.get('/2.2/users', @options)

stack_exchange = StackExchange.new('stackoverflow',1)
puts stack_exchange.users

Make sure the HTTParty gem is in your application's Gemfile.

Take example.rb and put it in /app/models/stack_exchange.rb — yes the file name does matter[0] (this isn't the purists place to put this, but for beginners it's fine and perfectly acceptable). Remove the code at the bottom you're using to test it as well.

in routes.rb add this route: get '/test' => 'application#test'

in your application_controller.rb add this method:

def test
  stack_client = StackExchange.new('stackoverflow', 1)
  @users = stack_client.users

in app/views/application/test.html.erb put the following:

<% @users.each do |user| %><%=user.inspect%><br/><br/><% end %>

Note: I would otherwise recommend adding views to ApplicationController but because I don't know anything about your application, I'll default to it.

hit http://localhost:3000/test and you should see the expected result.

[0] Rails does a lot "magic" under the scenes — it's really not magic but metaprogramming — where it tries to assume a lot of things about your application structure and naming conventions. If your class was named Stackexchange (note the lowercase e), stackexchange.rb would be automatically "mapped" to the class Stackexchange.
