Template preview

The base template was built with Mailchimp editor :

Requirements

This Django app works with :

• Python (>=2.7)
• Django (>=1.9) (Need to be tested for previous versions)

Todo

• Write tests
• validate compatibility with previous versions of Django and Python
• Set a demo app on pythonanywhere

Installation

Install using pip :

pip install django_simple_mail

Add simple_mail to your INSTALLED_APPS settings.

INSTALLED_APPS = (
    ...
    'simple_mail',
    ...
)

Then run :

python manage.py migrate

Quoting Django's documentation :

Mail is sent using the SMTP host and port specified in the EMAIL_HOST and EMAIL_PORT settings. The EMAIL_HOST_USER and EMAIL_HOST_PASSWORD settings, if set, are used to authenticate to the SMTP server, and the EMAIL_USE_TLS and EMAIL_USE_SSL settings control whether a secure connection is used.

So you need to set the following

EMAIL_HOST = ''
EMAIL_PORT = 587
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False

Integrations

CKEDITOR for a WYSIWYG edition of contents

Simple Mail easily integrates with django-ckeditor to have a wysiwyg edition of content. To use it :

pip install django-ckeditor

Then add ckeditor to your INSTALLED_APPS settings.

INSTALLED_APPS = (
    ...
    'ckeditor',
    ...
)

And set the following in your settings :

SIMPLE_MAIL_USE_CKEDITOR = True

ModelTranslation to translate emails

Simple Mail easily integrates with django-modeltranslation to get the content of your emails available in multiple languages.

pip install django-modeltranslation

Then add modeltranslation to your INSTALLED_APPS settings.

INSTALLED_APPS = (
    ...
    'modeltranslation',
    ...
)

And set the following in your settings :

SIMPLE_MAIL_USE_MODELTRANSALTION = True

And run :

python manage.py sync_translation_fields

Create, register and send mails

Register Mail

Create a mails.py file in your app and define your mail.

The email_key attribute must not exceed 100 characters.

from simple_mail.mailer import BaseSimpleMail, simple_mailer


class WelcomeMail(BaseSimpleMail):
    email_key = 'welcome'


simple_mailer.register(WelcomeMail)

Then run ./manage.py register_mails to create those mail into the database.

The mail with key welcome will he be available for edition in your django admin.

Send an email

You can the send the WelcomeMail the following way :

welcome_mail = WelcomeMail()
welcome_mail.send(to, from_email=None, bcc=[], connection=None, attachments=[],
                   headers={}, cc=[], reply_to=[], fail_silently=False)

Passing variables to email

You can pass variable to email with the context attribute :

from simple_mail.mailer import BaseSimpleMail, simple_mailer


class WelcomeMail(BaseSimpleMail):
    email_key = 'welcome'
    context = {
        'title' : 'My email title',
        'user': 'the user'
    }


simple_mailer.register(WelcomeMail)

Or you can create a set_context method:

from simple_mail.mailer import BaseSimpleMail, simple_mailer


class WelcomeMail(BaseSimpleMail):
    email_key = 'welcome'

    def set_context(self, user_id, welcome_link):
        user = User.objects.get(id=user_id)
        self.context = {
            'user': user,
            'welcome_link': welcome_link
        }


simple_mailer.register(WelcomeMail)

You will then need to call the set_context before sending an email:

welcome_mail = WelcomeMail()
welcome_mail.set_context(user_id, welcome_link)
welcome_mail.send(to, from_email=None, bcc=[], connection=None, attachments=[],
                   headers={}, cc=[], reply_to=[], fail_silently=False)

Email preview and test email

From the admin you can preview an email and send a test email.

Both methods use your context attribute to render the email.

If you use the set_context method, you might need to create a set_test_context method.

This method should not take any argument :

from simple_mail.mailer import BaseSimpleMail, simple_mailer


class WelcomeMail(BaseSimpleMail):
    email_key = 'welcome'

    def set_context(self, user_id, welcome_link):
        user = User.objects.get(id=user_id)
        self.context = {
            'user': user,
            'welcome_link': welcome_link
        }

    def set_test_context(self):
        user_id = User.objects.order_by('?').first().id
        self.set_context(user_id, 'http://my-webiste.com/my-path')


simple_mailer.register(WelcomeMail)

This method impact the fields displayed in the Context section of the admin.
