HEy Chris do you know a way to configure rspec with rails 4 

Posted in docker mysql

Hey guys i was wondering if you ever get to connect a rails app in local host without dockerizing it and be able to use a docker image of mysql with it.

i already got the mysql image running in docker ps but i would like to be able to get access to it from my rails apps that are not dockerized anybody knows how to achieve this?

i dont have more code but i do have the spec which needs to pass, i havent been able to resolve it yet

require_relative 'game'
require_relative 'dsl'
describe Game do
  context '#move' do
    it 'should not move unless called within a light' do
      game = Game.play do |g|
        g ||= self
        g.move
      end
      expect(game.distance).to eq 0a
    end
  end

  context '#redlight!' do
    it 'should do nothing if move was not called' do
      game = Game.play do |g|
        g ||= self
        g.redlight! {}
      end
      expect(game.result).to be_nil
    end

    it 'should finish and lose the game if move is called' do
      game = Game.play do |g|
        g ||= self
        g.redlight! do
          g.move
        end
      end
      expect(game.lost?).to be true
      expect(game.distance).to eq 0
    end
  end

  context '#greenlight!' do
    it 'should move if move is called' do
      game = Game.play do |g|
        g ||= self
        g.greenlight! do
          g.move
        end
      end
      expect(game.distance).to eq 10
    end

    it 'should finish and win the game if move is called enough times' do
      game = Game.play do |g|
        g ||= self
        g.greenlight! do
          11.times do
            g.move
          end
        end
      end

      expect(game.won?).to be true
      expect(game.distance).to eq 100
    end
  end

  context 'bonus' do
    it 'should be a true dsl' do
      begin
        game = Game.play do
          greenlight! do
            3.times { move }
          end

          redlight! {}

          greenlight! do
            2.times {move}
          end

          redlight! {}

          greenlight! do
            3.times {move}
          end

          greenlight! do
            2.times {move}
          end
        end
        expect(game.won?).to be true
      rescue NoMethodError
        # fail
      end
    end
  end
end

I have trouble solving the following excercise, i was wondering if there is any way in ruby where i can get which method called which i think caller but i havent figured out yet

require_relative 'game'
class Game::DSL
  MOVE_DISTANCE = 10
  WIN_DISTANCE  = 100

  def initialize(game)
    @game = game
  end

  # TODO
  # Moving during a redlight will cause the game to end and lose
  def redlight!
  end

  # TODO
  # Moving during a greenlight will allow the player to move
  def greenlight!
  end

  # TODO
  # If called outside a #greenlight! or #redlight! nothing happens
  # Moves the player MOVE_DISTANCE
  # If MOVE_DISTANCE >= WIN_DISTANCE game ends and wins
  def move
  end
end
class Game
  STATUS  = %i[standby playing finished]
  RESULTS = %i[won lost]

  attr_accessor :result, :distance

  def self.play(&block)
    new.play(&block)
  end

  def initialize
    @status   = :standby
    @distance = 0
    @dsl = Game::DSL.new(self)
  end

  # TODO Bonus!
  # Change this so the game truly acts like a DSL
  def play
    catch :finish! do
      start!
      yield @dsl
      finish!
    end
    self
  end

  def start!
    @status = :playing
  end

  # NOTE Call me from Game::DSL to end the game!
  def finish!
    @status = :finished
    freeze
    throw :finish!
  end

  # Defines #result=
  # Ensures you don't typo out of the valid results
  def result=(value)
    raise "'#{value}' is not a valid result. (Check for Typos)" unless RESULTS.include? value
    @result = value
  end

  # Defines #standby? #playing? #finished?
  STATUS.each do |status|
    define_method("#{status}?") { @status == status }
  end

  # Defines #won? #lost?
  RESULTS.each do |result|
    define_method "#{result}?" do
      raise "##{__method__} called before game finished!" unless finished?
      @result == result
    end
  end
end

I put comments in it
