It’s Boxing Day, we’re stuffed with turkey and wondering what to do with all those leftovers. What’s left to do except watch some festive TV and grab a final mince pie or two?

Hang on. Rustling through the empty sweet-wrappers of our Anvil Advent Calendar, it seems that we have one final app to share with you after all!

🎄 The Twelve Emoji of Christmas

As you know, the twelve days of Christmas actually start on Christmas Day itself and continue into January - a traditional time of merriment and gifting that inspired the old carol.

Since we already have a fun app for sending emoji to people I figured why not adapt it for a final festive treat?

https://twelve-emoji-of-christmas.anvil.app

Python’s built in datetime module lets us work out if it’s one of the twelve days of Christmas.

@anvil.server.callable
def is_xmas_season():
  """
  Let's find out if it's one of the twelve days of Christmas
  """
  today = date.today()  # Find out today's date

  beginning = date(2020, 12, 25)
  diff = today - beginning
  
  if diff.days < 13 and diff.days >= 0:
    return diff.days + 1
  
  return False

If so, we check which emoji gifts to display under our tree - which is easy given Python3’s native support for Unicode strings!

@anvil.server.callable
def get_emoji_for_day(n_xmas):
  """ Return the right gift emojis for the day of Christmas that you want """
  xmas_moji = {
              1: '🦃🌳',
              2: '🕊🕊',
              3: '🐓🐓🐓',
              4: '🐦🐦🐦🐦',
              5: '💍💍💍💍💍',
              6: '🐔🐔🐔🐔🐔🐔',
              7: '🦢🦢🦢🦢🦢🦢🦢',
              8: '👩‍🌾👩‍🌾👩‍🌾👩‍🌾👩‍🌾👩‍🌾👩‍🌾👩‍🌾',
              9: '💃💃💃💃💃💃💃💃💃',
              10: '🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃',
              11: '🎷🎷🎷🎷🎷🎷🎷🎷🎷🎷🎷',
              12: '🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁'}
  
  moji = [xmas_moji[n] for n in range(1, n_xmas)]
  return '\n'.join(moji)

The final touch: using Anvil’s Email Service and User Service I created a simple subscription flow that allows users to sign up for daily festive updates with the right emoji gifts in their inbox.

Unsubscription is easy, using a custom token generated for each user to keep things secure, just like the Fruitmoji app.

Play with it yourself

Anvil makes it easy to build knock together a front-end with email capability. To check out the source code for this app in more detail, you can clone it using the link below:
