I am able to write parts of the code but I am not able to join the code
and use loops. I am quite new to RUBY and trying to do this project.
We have a list of customers
We have a list of products.
The customer is asked if he is new or returning
A new customer puts in his information and the customer database is
populated with his information if new customer
if existing customer, then with his name his details are pulled from the
database
Then he has to enter the shopping cart with the product names and
quantity,
Then from the product table, the price of the product table, the price
of the product and the total (quantity*price) is calculated
in the end
it should print out the list of the products quantity price
total sum
tax
shipping
and
total= total sum+tax+shipping
all this information should be in a new csv file with the customer
information and saved in the folder.
this is what I have so far and I am freaking out.Its all over the place
require 'csv'
# Getting Information from the new customer and updating the csv file
puts "Are you a new cuntomer? y/n"
ans = gets.chomp
while ans == 'y' do
module CustomerRelated
class Customer
def initialize( customer_id, fname, lname, address1, address2, city,
state, zip, ph_no)
@fname = fname
@lname = lname
@address1 = address1
@address1 = address1

@state = state
@zip = zip
@ph_no = ph_no
