We've also included a line to add the Linux deployment platform, which is required on some systems. 3 | 4 | \begin{codelisting} 5 | \label{code:bundle_without_production} 6 | \codecaption{Bundling without production gems.} 7 | %= lang:console 8 | \begin{code} 9 | $ bundle _2.3.14_ config set --local without 'production' 10 | $ bundle _2.3.14_ install 11 | $ bundle _2.3.14_ lock --add-platform x86_64-linux 12 | -------------------------------------------------------------------------------- /Listing_1.23.txt: -------------------------------------------------------------------------------- 1 | $ source <(curl -sL https://cdn.learnenough.com/heroku_install) 2 | -------------------------------------------------------------------------------- /Listing_1.24.txt: -------------------------------------------------------------------------------- 1 | $ heroku create 2 | Creating app... done, ⬢ thawing-refuge-35095 3 | https://thawing-refuge-35095.herokuapp.com/ | 4 | https://git.heroku.com/thawing-refuge-35095.git 5 | -------------------------------------------------------------------------------- /Listing_1.25.txt: -------------------------------------------------------------------------------- 1 | $ heroku apps:info 2 | === mysterious-atoll-47182 3 | . 4 | . 5 | . 6 | Web URL: https://mysterious-atoll-47182.herokuapp.com/ 7 | -------------------------------------------------------------------------------- /Listing_1.3.txt: -------------------------------------------------------------------------------- 1 | $ gem install bundler -v 2.3.14 2 | -------------------------------------------------------------------------------- /Listing_1.4.txt: -------------------------------------------------------------------------------- 1 | $ source <(curl -sL https://cdn.learnenough.com/resize) 2 | -------------------------------------------------------------------------------- /Listing_1.5.txt: -------------------------------------------------------------------------------- 1 | # These steps are not needed on the cloud IDE. 2 | $ cd # Change to the home directory. 3 | $ mkdir environment # Make an environment directory. 4 | $ cd environment/ # Change into the environment directory. 5 | -------------------------------------------------------------------------------- /Listing_1.9.txt: -------------------------------------------------------------------------------- 1 | $ cd hello_app/ 2 | $ bundle _2.3.14_ install 3 | Fetching source index for https://rubygems.org/ 4 | . 5 | . 6 | . 7 | -------------------------------------------------------------------------------- /Listing_10.10.txt: -------------------------------------------------------------------------------- 1 | $ rails test 2 | -------------------------------------------------------------------------------- /Listing_10.12.rb: -------------------------------------------------------------------------------- 1 | class UsersController < ApplicationController 2 | . 3 | . 4 | . 5 | def update 6 | @user = User.find(params[:id]) 7 | if @user.update(user_params) 8 | flash[:success] = "Profile updated" 9 | redirect_to @user 10 | else 11 | render 'edit', status: :unprocessable_entity 12 | end 13 | end 14 | . 15 | . 16 | . 17 | end 18 | -------------------------------------------------------------------------------- /Listing_10.13.rb: -------------------------------------------------------------------------------- 1 | class User < ApplicationRecord 2 | attr_accessor :remember_token 3 | before_save { self.email = email.downcase } 4 | validates :name, presence: true, length: { maximum: 50 } 5 | VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i 6 | validates :email, presence: true, length: { maximum: 255 }, 7 | format: { with: VALID_EMAIL_REGEX }, 8 | uniqueness: true 9 | has_secure_password 10 | validates :password, presence: true, length: { minimum: 6 }, allow_nil: true 11 | . 12 | . 13 | . 14 | end 15 | -------------------------------------------------------------------------------- /Listing_10.14.txt: -------------------------------------------------------------------------------- 1 | $ rails test 2 | -------------------------------------------------------------------------------- /Listing_10.15.rb: -------------------------------------------------------------------------------- 1 | class UsersController < ApplicationController 2 | before_action :logged_in_user, only: [:edit, :update] 3 | . 4 | . 5 | . 6 | private 7 | 8 | def user_params 9 | params.require(:user).permit(:name, :email, :password, 10 | :password_confirmation) 11 | end 12 | 13 | # Before filters 14 | 15 | # Confirms a logged-in user. 16 | def logged_in_user 17 | unless logged_in?
