Django-Mail-Templated

This is a fork of https://github.com/maximilianhurl/django-mail-templated. that includes support for Django 4.2

Tested against Django 3.2, 4.0, 4.1 and 4.2 on Python 3.8, 3.9, 3.10 and 3.11.

Overview

This is a tiny wrapper around the standard EmailMessage class and send_mail() function. Just pass template_name and context as the first parameters then use as normal.

Installation

Run:

$ pip install git+https://github.com/dabapps/django-mail-templated.git

And register the app in your settings file:

INSTALLED_APPS = (
    ...
    'mail_templated'
)

Usage

Write a template to send a plain text message. Note that first and last newline will be removed:

{% block subject %}
Hello {{ user.name }}
{% endblock %}

{% block body %}
This is a plain text message.
{% endblock %}

Or for an html message:

{% block subject %}
Hello {{ user.name }}
{% endblock %}

{% block html %}
This is an <strong>html</strong> message.
{% endblock %}

Or for a multipart message you can use both blocks:

{% block subject %}
Hello {{ user.name }}
{% endblock %}

{% block body %}
This is a plain text message.
{% endblock %}

{% block html %}
This is an <strong>html</strong> message.
{% endblock %}

Or leave out some block to set it manually later with EmailMessage class:

{% block body %}
This is a plain text message.
{% endblock %}

Now you can send it:

from mail_templated import send_mail
send_mail('email/hello.tpl', {'user': user}, from_email, [user.email])

You can add in BCC like this:

send_mail('email/hello.tpl', {'user': user}, from_email, [user.email], bcc=[user2.email])

You can also add an attachment like this:

send_mail('email/hello.tpl', {'user': user}, from_email, [user.email], attachment="file/path.pdf")

Or if you wish to add more control over message creation then use the class form:

from mail_templated import EmailMessage
message = EmailMessage('email/hello.tpl', {'user': user}, to=[user.email])
# ... attach a file, etc
message.send()

That's all. Please create an issue at GitHub if you have any notes, ...or just email :)

Extends

You can extend templates like so:

{% extends "email_base.tpl" %}

{% block subjectcontent %}
Subject
{% endblock %}

{% block bodycontent %}
 This is a plain text message.
{% endblock %}

{% block htmlcontent %}
This is an <strong>html</strong> message.
{% endblock %}

and email_base.tpl would look like this:

{% block subject %}
{% block subjectcontent %}{% endblock %}
{% endblock %}

{% block body %}
A heading or logo
{% block bodycontent %}{% endblock %}
{% endblock %}

{% block html %}
A heading or logo
{% block htmlcontent %}{% endblock %}
{% endblock %}

Please note that you must include all blocks in the base template file.

If you dont include one of the blocks in the base template it will not be shown. So you cannot, for example, move the subject block into the top file.

Tests

To run the unit tests you first need to create a virutal env in project root directory.

python3 -m venv env

Then you need to install the test requriements.

env/bin/pip install -r requirements.txt

Now you can run the unit tests using the following command.

env/bin/python mail_templated/tests/runtests.py
