Cheat Sheets are greate but they are not a substitute for learning the framework and reading the documentation as we most certainly have not covered every potential example here. Please refer to the Rails Command Line Docs for more information.

Command Line Generator Info

Reference

You can get all of this information on the command line.

rails generate with no generator name will output a list of all available generators and some information about global options. rails generate GENERATOR --help will list the options that can be passed to the specified generator.

First, add pry-rails to your Gemfile:
https://github.com/rweng/pry-rails

gem 'pry-rails', group: :development

Then you'll want to rebuild your Docker container to install the gems

	FROM ruby:2.3.1

	# Install dependencies
	RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs

	# Set an environment variable where the Rails app is installed to inside of Docker image:
	ENV RAILS_ROOT /var/www/app_name
	RUN mkdir -p $RAILS_ROOT

	# Set working directory, where the commands will be ran:

	#!/bin/bash

	# For headless Chrome (although not necessary with --headless option).
	#
	sudo apt-get install xvfb

	sudo apt-get install unzip

	CHROME_DRIVER_VERSION=`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`

	require 'mina/rails'
	require 'mina/git'
	require 'mina/puma'
	require 'mina/rvm'
	require 'yaml'

	set :user, 'deploy'
	set :port, '22'
	set :forward_agent, true
	set :term, :system

	# load into test setup after `require 'capybara/rails'`
