Sinatra Nested Forms Lab: Superheroes!

Overview

In this lab, you'll practice building nested forms in Sinatra for creating teams of superheroes. No database is required, but feel free to add persistence after you have successfully completed the instructions below.

Instructions

Make a form

1. Create a route that responds to a GET request at /.
2. Create a view with a form and render it in the GET / route.
3. The form should have fields for the name of a superhero team and their motto.
4. There should be form inputs for each of the three superhero members' name, power, and bio.

It should look something like this:

Handle form submission

1. Create a route that responds to a POST request at /teams.
2. Have the form send a POST request to this route.
3. Upon submission, render a template that displays the submitted team data and each member's data.

Final Output

Your params should be nested. For example, in order to see all the superheroes for the team you just created you would enter:

params["team"]["members"]

If you wanted to access the first superhero's name, you would enter:

params["team"]["members"][0]["name"]

When you post to this form you should render a page that displays the name of the team and each member of the team, including their name, super power and bio.

Your view should display something like this:

Deliverables

Pass the tests! You'll notice in super_sinatra_spec.rb in the it submits the form test for 'POST /teams', we use the Capybara method fill_in:

fill_in("member1_name", :with => "Amanda")
fill_in("member1_power", :with => "Ruby")
fill_in("member1_bio", :with => "I love Ruby!")

The same pattern follows for the second and third superheroes. The word in quotes after fill_in needs to be set as an ID in the form to create the superheroes:

<input id="member1_name" type="text" name="team[members][][name]">

NOTE: If you run into any trouble with Sinatra's default configuration, such as needing to set the views directory for a particular controller (or to something other than the default views folder at the top level of your application directory), take a spin through the Sinatra configuration documentation, the Getting Started guide, or the old standbys, Google and StackOverflow.
