from sqlalchemy import *
import random

engine = create_engine('sqlite:///raffle.db')

metadata = MetaData(bind=engine)

raffles_table = Table('raffles', metadata,
        Column('id', Integer, primary_key=True),
        Column('email', String(40)),
        Column('raffle_color', String(40)),
        Column('raffle_ticket', Integer),
        )

# create tables in database
metadata.create_all(checkfirst=True)

# create a database connection
conn = engine.connect()

def add_raffles():
    email = input("Please enter your email address:")
    num_tickets = int(input("How many tickets do you want:"))

    for i in range(num_tickets):
        ins_raffle = raffles_table.insert()
        colors = ['blue','Pink','Plum','Aqua','Navy','Grey','Rose','Ruby','Teal','Gold','Jade','Lime']
        color = random.choice(colors)
        ticket = random.randrange(1000,9999)
        new_raffle = ins_raffle.values(email = email, raffle_color = color, raffle_ticket = ticket)
        # add raffle to database by executing SQL
        conn.execute(new_raffle)
        print(color + "   " + str(ticket))

def select_winner():
    winner_query = raffles_table.select().order_by(func.random()).limit(2)
    winner = conn.execute(winner_query)
    for row in winner:
        print("The winner is:" + row['email'])
        print("The winning raffle is:" + row['raffle_color'] +"  " + str(row['raffle_ticket']))
