Rails Forms Lab

Overview

In this lab, you'll practice building forms in Rails by creating a basketball team sign-up sheet. Your application will use Rails form helpers with proper RESTful routing conventions, and will display the data from the form after it has been submitted by the user.

Instructions

1. Run bundle install

2. Run bin/rails server

3. Set up your routes in config/routes.rb:

   • Use the resources method to create RESTful routes for teams
   • This will automatically create routes for new, create, show, etc.

4. Create controller actions in app/controllers/teams_controller.rb:

   • Add a new action to display the form (should set up an @team instance variable)
   • Add a create action to process the form submission and redirect to the show action
   • Add a show action to display the team information

5. Build the form in app/views/teams/new.html.erb:

   • Use Rails form_with helper with the @team model object
   • The form will automatically submit to the correct RESTful endpoint
   • Add fields for: Team name ('name'), Coach ('coach'), Point Guard ('pg'), Shooting Guard ('sg'), Power Forward ('pf'), Small Forward ('sf'), Center ('c')
   • Include a submit button (any text or styling is fine)
   • The form fields should use nested naming (e.g., team[name], team[coach], etc.)

6. Display the results in app/views/teams/show.html.erb:

   • Show all the submitted team information
   • Display each field with labels like "Team Name: [name]", "Coach: [coach]", etc.
   • Use the @team instance variable passed from your controller

Testing

Run bundle exec rspec to test your implementation. Make sure all tests pass!

The tests will check that:

• Your routes are set up correctly using RESTful conventions
• Your form has all the required fields with proper nested naming
• Your form submits to the correct RESTful endpoint
• Your show page displays all the submitted data correctly

Rails Conventions You'll Practice

• RESTful routing: Using resources :teams for standard CRUD operations
• Form helpers: Using form_with with model objects for automatic routing
• Nested parameters: Form fields using team[attribute_name] format
• Controller actions: Following the standard new, create, show pattern
• Redirects: Redirecting after successful form submission to the show page
