Building a multiple choice game

Hi guys, I'm trying to build a multiple choice app. Below is what I have so far:


class Answer < ActiveRecord::Base
      belongs_to :question

class Question < ActiveRecord::Base
      has_many :answers


class QuizzesController < ApplicationController
def show
    @question = Question.find(params[:id])
    @answer = Answer.find(params[:id])


ActiveRecord::Schema.define(version:      20150418024450) do

  create_table "answers", force: :cascade do |t|
    t.string   "wrong_answer_1"
    t.string   "wrong_answer_2"
    t.string   "wrong_answer_3"
    t.string   "correct_answer"
    t.datetime "created_at",     null: false
    t.datetime "updated_at",     null: false
    t.integer  "question_id"

  add_index "answers", ["question_id"], name:     "index_answers_on_question_id"

  create_table "questions", force: :cascade do |t|
    t.string   "question"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false




<%= @question.question %>

<% @question.answers.each do |answer| %>
    <%= radio_button_tag("answer[question.id]", answer.id) %>
    <%= label("answer_".concat(answer.id.to_s).to_sym,    answer.wrong_answer_1) %>
<% end %>

I have a couple questions. First of all, how do I add all of my answers (wrong_answer_1, wrong_answer_2, etc.) in here:

<%= label("answer_".concat(answer.id.to_s).to_sym,    answer.wrong_answer_1) %>

How would i create a button that when clicked would flash either success or failure depending on if the correct answer was selected?

Thanks for the help!

Sorry I can't spend much time on this, but I think you need to build a form_tag:

<%= form_tag check_answer_path do %>
 #stuff in here
<% end %>

...using multiple radio_button_tags for the answers. Then use a submit_tag for the button. The form_tag will point to a custom method that you have written in your QuizzesController, called 'check_answer'. Your routes.rb file will have

post 'check_answer' => 'quizzes#check_answer'

I'm sorry I can't do much more right now - way too late. Hopefully that was of some help. The tricky part is the 'stuff in here' part (and the controller method I guess, but less so).
