django-mail-builder

Build EmailMessages easily from templates

QuickStart

In your code, you can use the build_message function to build an EmailMessage class, sourcing its values from a template.

def build_message(template_names, extra_context=None, force_multipart=False,
                  **defaults):

Parameters:

template_names:: A list of template names to select from. A single template name will be wrapped in a list.

extra_context:: Extra context to be passed when rendering blocks from the template.

force_multipart:: Force use of EmailMultipartMessage instead of EmailMessage.

If a html block is provided then EmailMultipartMessage will be used anyway.

defaults:: Default values to be passed to the message class. These will be overidden by any template blocks.

Template blocks

Scalar fields:

These blocks will be rendered as is, and passed to the message. If an 'html' block is passed, a EmailMultipartMessage will be constructed, and the html content will be added as a text/html alternative.

• subject
• from_email
• body
• html

List fields:

These blocks will be rendered, and then split by lines using str.splitlines.

• to
• bcc
• cc
• reply_to

Views

A utility view is provided that extends django.views.generic.FormView to send an email on form valid.

from mail_builder.views import EmailFormView

When form_valid is called, it will build a message using email_template, and pass the form's cleaned_data in context as form. It will then send the message using the fail_silently flag as set on the class.

Additional class properties:

• email_template
• email_kwargs = {}
• fail_silently = False

Two extra methods are added to allow control over context and params:

    def get_email_context(self, form, **kwargs):
        kwargs.setdefault('form', form.cleaned_data)
        return kwargs

    def get_email_kwargs(self, form, **kwargs):
        kwargs.update(self.email_kwargs)
        return kwargs

Template Tags

Two template tags have been added to help embeding files into your emails.

To use them, add mail_builder to your INSTALLED_APPS setting, and include {% load mailbuilder %} in your template.

    <img src="{% cid_static 'static/file/name.png' %}">
    <img src="{% cid_media user.icon %}">

This will render the files using "cid" URIs, and place MIMEImage objects in a list in the context.
