Background & Objectives

hey ho

The goal of the next two challenges is to re-implement some of your ruby scripts in Rails. That means:

• Your program interface isn't the terminal anymore, it is your browser now.
• The only way to communicate with your Rails app is through HTTP requests.

Re-implement the stupid coaching challenge (01-Ruby/01-Programming-basics/05-Stupid-coaching) in Rails.

Specs

Get familiar with Rails command line basics. For this exercise, you should know at least how to:

• create a new Rails app
• launch a web server to test your app locally
• generate a new controller from the command line
• check your routes with the relevant rake task

Generate a CoachingController

Once you have created your new coaching app, add a new CoachingController, using the adequate rails generator on the command line. This controller will have two actions, CoachingController#answer and CoachingController#ask

Your coach answer logic

Implement a first route GET '/answer' to your CoachingController#answer action. The answer.html.erb will display the question you ask your coach as well as his answer.

Your question to your coach should be given as a parameter named :query. Ex: GET /answer?query=hello or GET /answer?query=what+should+i+do?.

Ask a question using a form

Implement a new route GET '/ask' to your CoachingController#ask action. This action is here to build the page including your HTML form. Here is the code for the form.

<form action="/???">
  <label for="question">Speak to your coach</label>
  <input type="text" id="question" name="???" placeholder="what time is it?">
  <input type="submit" value="Go on!">
</form>

Notice the important HTML attributes in the form:

• action specifies the URL that will be used when submitting the form
• name enables you to name each parameter corresponding to each input of the form.

Replace the ??? so that your form send a request to CoachingController#answer with a good parameter name.

Add a backlink in answer.html.erb

• Add a link to /ask on the answer.html.erb view using the link_to Rails helper.
