takeaway

Summary

Restaurant menu with Twilio API call

Problem

• Implement the following functionality:
• list of dishes with prices
• placing the order by giving the list of dishes, their quantities and a number that should be the exact total. If the sum is not correct the method should raise an error, otherwise the customer is sent a text saying that the order was placed successfully and that it will be delivered 1 hour from now, e.g. "Thank you! Your order was placed and will be delivered before 18:52".
• The text sending functionality should be implemented using Twilio API
• Make sure that your Takeaway class is thoroughly tested and that you use mocks and/or stubs, as necessary to not to send texts when your tests are run
• However, if your Takeaway class is loaded into IRB and the order is placed, the text should actually be sent

Ruby		Rspec	Twilio

Solution

• Classes include dish, menu and order, customer and twilio

Setup

• You'll need to register with Twilio and save the API keys as environment variables TWILIO_SID TWILIO_AUTH_TOKEN TWILIO_PHONE_NUMBER RECEIVING_PHONE_NUMBER
• The classes are then accessed in IRB

`2.0.0-p594 :003 > %w(dish customer menu order).each {|file| require_relative file+'.rb'}
 => ["dish", "customer", "menu", "order"]
2.0.0-p594 :005 > egg = Dish.new('egg',1)
 => #<Dish:0x007fb97223add8 @name="egg", @price=1>
2.0.0-p594 :006 > bacon = Dish.new('bacon',2)
 => #<Dish:0x007fb9721ccdd8 @name="bacon", @price=2>
2.0.0-p594 :007 > menu = Menu.new([egg,bacon])
 => #<Menu:0x007fb97215ab98 @dishes=[#<Dish:0x007fb97223add8 @name="egg", @price=1>, #<Dish:0x007fb9721ccdd8 @name="bacon", @price=2>]>
2.0.0-p594 :008 > customer = Customer.new('Chris')
 => #<Customer:0x007fb97210fc10 @order="Chris">
2.0.0-p594 :009 > order = Order.new
 => #<Order:0x007fb9720f6580 @dishes={}>
2.0.0-p594 :011 > order.choose(egg)
 => 1
2.0.0-p594 :012 > order.choose(bacon)
 => 1
2.0.0-p594 :014 > order.total_price
