=====
Usage
=====

django-mailing was developed to:
 * send emails in ASCII or HTML
 * support email templating with headers and footers
 * support multilingual environments
 * optionally use SendGrid to categorize email statistics and sync email lists
 * optionally support celery for queuing mail sending and/or processing in background processes

Installation
============

Available on PyPi:

pip install django-mailing

Configuration
=============

Add to your installed apps in your setting.py file:

INSTALLED_APPS = (
    ...
    'mailing',
    )

settings.DEFAULT_FROM_EMAIL
---------------------------

You need to set your default from email:

DEFAULT_FROM_EMAIL = 'contact@mydomain.com'

settings.MAILING_USE_SENDGRID
-----------------------------

Boolean to indicate you have configured Django to use SendGrid:

MAILING_USE_SENDGRID = True

The impact is you now have additional SendGrid capabilities such as the ability to:
 * categorize emails sent
 * manage/sync mailing lists (currently not implemented)
 * plus all the good stuff they do on their side.

settings.MAILING_MAILTO_HIJACK
------------------------------

You can hijack email sent by your app to redirect to another email. Quite practical when developing or testing with external email addresses:

MAILING_MAILTO_HIJACK = 'me@mydomain.com'

If defined, every outgoind email will be sent to me@mydomain.com. For debugging/testing purposes, the following header is added to the email:

X-MAILER-ORIGINAL-MAILTO: me@mydomain.com

It will contain what would have been the original "To" header if we hadn't hijacked it

settings.MAILING_USE_CELERY
---------------------------

Boolean indicating celery is configured and you want to send/process email related stuff in background:

MAILING_USE_CELERY = True

For example, you can configure your app to use celery by installing a redis server.

Your settings would also need to include things like:

INSTALLED_APPS = (
        #
        # ...
        #

'celery',
        'djcelery',

#
        # ...
        #

'mailing',

#
        # ...
        #
    )
    
    # 
    # ...
    #
    
    # Celery Configuration. Ref.: http://celery.github.com/celery/configuration.htm
    # -------------------------------------
    os.environ["CELERY_LOADER"] = "django"
    djcelery.setup_loader()

BROKER_TRANSPORT = "redis"
    BROKER_HOST = "localhost"  # Maps to redis host.
    BROKER_PORT = 6379         # Maps to redis port.
    BROKER_VHOST = "0"         # Maps to database number.

CELERY_IGNORE_RESULT = False
    CELERY_RESULT_BACKEND = "redis"
    CELERY_REDIS_HOST = "localhost"
    CELERY_REDIS_PORT = 6379
    CELERY_REDIS_DB = 0

When running the celery daemon, you need to include the ``mailing`` app in the tasks through the ``include`` parameter. Example:

manage.py celeryd --verbosity=2 --beat --schedule=celery --events --loglevel=INFO -I mailing

You therefore could run a separate celery daemon to run your mailing tasks independently of other tasks if the need arises.

settings.MAILING_LANGUAGES
--------------------------

Not yet implemented.

Replacing the core django send_mail function
--------------------------------------------

To replace Django's core send_mail function to add support for email templates, SendGrid integration and background celery sending, add the following code to your settings file:

import sys
    from mailing.mail import send_email_default
    try:
        from django.core import mail 
        mail.send_mail = send_email_default
        sys.modules['django.core.mail'] = mail
    except ImportError:
        pass

Using django-mailing
====================

Simple multi-part send_mail replacement
---------------------------------------

You can using mailing.send_email instead of Django's send_mail to send multi-part messages:

send_email(recipients, subject, text_content=None, html_content=None, from_email=settings.DEFAULT_FROM_EMAIL, category=None, fail_silently=False, bypass_queue=False)

Parameters are:
 * ``recipients`` is a list of email addresses to send the email to
 * ``subject`` is the subject of your email
 * ``text_content`` is the ASCII content of the email
 * ``html_content`` is the HTML content of the email
 * ``from_email`` is a string and is the sender's address
 * ``category`` is a string and is used to define SendGrid's X-SMTPAPI's category header

You must supply at least text_content or html_content. If both aren't supplied, an exception will be raised. If only one of the two is supplied, the email will be sent in the corresponding format. If both content are supplied, a multi-part email will be sent.

Example usage:

from mailing import send_email
    
    send_email(['test1@mydomain.com', 'test@mydomain.com'], 'Testing 1,2,3...', 'Text Body', 'HTML Body', category='testing')

Rendering and sending emails using templates
--------------------------------------------

To use Django templates to generate dynamic emails, similar to using ``render_with_context`` in a Django view, use the ``render_send_email`` shortcut:

render_send_email(recipients, template, data, from_email=settings.DEFAULT_FROM_EMAIL, subject=None, category=None, fail_silently=False, language='en', bypass_queue=False)

Parameters are:
 * ``recipients`` is a list of email addresses to send the email to
 * ``template`` the path to your Django templates, without any extension
 * ``data`` data context dictionnary to render the template
 * ``from_email`` is a string and is the sender's address
 * ``subject`` is the subject of your email
 * ``category`` is a string and is used to define SendGrid's X-SMTPAPI's category header

Example:

def send_welcome_email(user):
        from mailing.shortcuts import render_send_email
    
        render_send_email(['test1@mydomain.com', 'test@mydomain.com'], 'users/welcome', {'user': user}, category='welcome')

in your app, you would need the following template files with the right extensions:
 * ``templates/users/welcome.txt``
 * ``templates/users/welcome.html``
 * ``templates/users/welcome.subject``

The subject template file can be omitted but you then need to supply the ``subject`` parameter. If you do not create a template with a .txt or a .html extension, then the associated format won't be included in the email. So, if you want to only send ASCII messages, do not create a .html file.

Example without using a subject template:

render_send_email(['test1@mydomain.com', 'test@mydomain.com'], 'app/welcome', data, subject='Welcome new user', category='welcome')

Templates
---------

The following templates are defined and used by django-mailing and should be overriten in your own templates:
 * ``templates/mailing/base.txt``
 * ``templates/mailing/base.html``

These are used to define your email overall look like the header and footer. The only requirement is to include the ``{{ content }}`` template variable. It is there than the supplied content of your email will be inserted in your base template.
