Table with count method react Cheat Sheet

Step

1. new Rails application	rails new dog-app -T
2. directory to access	cd dog-app/
3. Generate the model	rails g model dog name motto
	This creates 2 files: app/models/dog.rb db/migrate/[date_time]_create_dogs.rb The dog table in our database will have 2 fields: name and motto.
4. Generate the controller	rails g controller dogs index show new edit
5. The config/routes.rb file also gets automatically updated:

5. Update the config/routes.rb

Rails.application.routes.draw do
  resources :dogs
end

6. migrate our data

class CreateDogs < ActiveRecord::Migration[5.2]
  def change
    create_table :dogs do |t|
      t.string :name
      t.string :motto
      
      t.timestamps
    end
  end
end

rake db:migrate

7. Update the db/migrate/seeds.rb

Dog.create(name: 'Nala', motto: 'Born to be wild')
Dog.create(name: 'Alex', motto: 'Calm as can be')
Dog.create(name: 'Leroy', motto: 'Life of the pawty')
Dog.create(name: 'Belle', motto: 'Miss Independent')

rake db:seed

(1).config/routes.rb

1.config/routes.rb
Rails.application.routes.draw do
  resources :barangs
end

(2)db/migrate/20190510051736_create_barangs.rb

2.db/migrate/20190510051736_create_barangs.rb
class CreateBarangs < ActiveRecord::Migration[5.2]
  def change
    create_table :barangs do |t|
      t.string :sku
      t.string :nama
      t.integer :kuantitas
      t.integer :hargaBeli
      t.integer :hargaJual
      t.integer :profit

      t.timestamps
    end
  end
end

(3).db/seeds.rb

3.db/seeds.rb
Barang.create(sku:'AIR001', nama: 'Air mineral Aqui', kuantitas:10, hargaBeli: 3000, hargaJual: 6000, profit: 3000)
Barang.create(sku:'SOF001', nama: 'Choca Chola', kuantitas:20, hargaBeli: 5000, hargaJual: 4500, profit: -500)
Barang.create(sku:'SNK001', nama: 'Cheetah Toh', kuantitas:15, hargaBeli: 4000, hargaJual: 5000, profit:1000)

8. added to your database

In order to check if the dogs have been added to your database, run:

rails console or rails c

Type in Dog.all and you should see that the 4 dogs have been added.

FYI. Run rails routes or go to localhost:3000/rails/info/routes to see all routes your application is configured to:
