pingpong is a library to aimed at simplifying email in django.

You should probably send more email… and this will make it so easy that you don't think twice about it!

Installation

1. Install lib with pip:

   pip install pingpong

   - OR -

   Put the "pingpong" directory somewhere in your python path

2. Add "pingpong" to your installed apps (in the settings.py file)

A better way to fire off emails

from pingpong.email import render_to_email

def some_function():

    template = "emails/muffins.email"
    context = { "your_mom": "Betty Crocker", "muffin_type": "blueberry" }
    recipients = ['somebody@example.com']
    
    # send an email!
    render_to_email(template, context, recipients)

And the template, emails/my_email_template.email would be in your main templates folder:

Delicious muffins thanks to {{ your_mom }}


Hi friend,

I'm writing to let you know that {{ your_mom }} made some superb 
{{ muffin_type }} muffins. Please tell her thank you!

Passing system events to your app (and then sending an email?)

set up listeners:

# listeners.py

from pingpong.utils import pong

@pong("dailycron")
def email_admins_about_daily_activity(ping_name, args, kwargs, **kw):
    render_to_email(…)
    
    
# models.py

... your models...

import listeners

Then you trigger all functions listening to "dailycron" like so:

$ python manage.py pong dailycron

If you pass extra args to the management command they will get passed along...

$ python manage.py pong cachecleared memcache:38174

You can use pong to pass any system event into your app.

In this case we're letting the app know that memcache on port 38174 just got cleared.

from pingpong.utils import pong

@pong("cachecleared")
def warm_up_cache(ping_name, args, kwargs, **kw):
    assert ping_name == "cachecleared"
    assert args[0] == "memcache:38174"
    
    cache_type, port = args[0].split(":")
    ...
