Welcome to Hack the North 2022 and to this workshop! We're Angela and Adison, your workshop leads. Ruby on Rails is a great tool to go with to kickstart your hackathon project and finish a working prototype within a short amount of time, so you have time for all the bells and whistles. In this workshop, you'll build your own web application from start to finish in only an hour with Rails!

Before you start, please make sure that you've checked out the Hack Pack for this workshop. This includes instructions on how to install Ruby, SQLite, and Rails.
Additionally, please run bundle install (mentioned early on in the slides).
[Work in Progress]
After cloning, please run bundle install as normal.
For every other command ran in the CLI for the remainder of the workshop, please insert "bundle exec" in front.

class CreateProductionCompanies < ActiveRecord::Migration[7.0]
def change
create_table :production_companies do |t|
t.string :name # company.name
t.string :homepage # company.homepage
t.timestamps
end
end
endNavigate to the migration file (for movies) created under db/migrate db/migrate:
class CreateMovies < ActiveRecord::Migration[7.0]
def change
create_table :movies do |t|
t.belongs_to :production_company
t.string :title # movie.title
t.text :overview # movie.overview
t.string :poster # movie.poster
t.date :release_date # movie.release_date
t.float :ratings # movie.vote_average
t.float :review # YOUR REVIEW (1.0-5.0)
t.boolean :watched # true if seen
t.timestamps
end

endInside the model created at app/models/movie.rb:
class Movie < ApplicationRecord
belongs_to :production_company
validates :review, numericality: { in: 1.0..10.0 }, :allow_nil => true
endNavigate to app/controllers/movies_controller.rb:
class MoviesController < ApplicationController
def index
@movies = Movie.all
end
def show
@movie = Movie.find(params[:id])
end
endStill inside app/controllers/movies_controller.rb:
def new
@movie = Movie.new
end
def create
@movie = Movie.new(movie_params)
if @movie.save
redirect_to @movie
else
render :new, status: :unprocessable_entity
end
endStill inside app/controllers/movies_controller.rb:
def edit
@movie = Movie.find(params[:id])
end
def update
@movie = Movie.find(params[:id])
if @movie.update(movie_params)
redirect_to @movie
else
render :edit, status: :unprocessable_entity
end
endInside app/controllers/movies_controller.rb:
def destroy
@movie = Movie.find(params[:id])
@movie.destroy!
redirect_to movies_path
endAt the very end of the same file, paste this:
private
def movie_params
params.require(:movie).permit(:watched,:review)
endUnder config/routes.rb, paste:
Rails.application.routes.draw do
resources :movies
root "movies#index"
