A Django app for sending newsletter by email to a contact list.
The problematic was :
How to couple a contact base to a mailing list and sending newsletters throught Django ?
Imagine that we have an application containing some kind of profiles or something like the django.contrib.auth and you want to send newsletters to them and tracking the activity.
- DBMS considerations
- HOWTO use TinyMCE for editing the newsletters
- HOWTO couple your profile application with emencia.django.newsletter
- Database Representation
More than a long speech, here the list of the main features :
- Coupling capacities with another django model.
- Variables can be used in the newsletter’s templates.
- Mailing list managements (merging, importing…).
- Import/Export of the contact in VCard 3.0.
- Configurable SMTP servers with flow limit management.
- Working groups.
- Can send newsletter previews.
- Subscriptions and unsubscriptions to mailing list.
- Attachments in newsletters.
- Unique urls for an user.
- Tracking statistics.
At the level of the application architecture, we can see 2 originalities who need to be explained.
The content types application is used to link any Contact model instance to another model instance. This allow you to create different kinds of contact linked to differents application, and retrieve the association at anytime.
This is particulary usefull with the templates variables if certain informations are located in the model instance linked.
The emencia.django.newsletter application will never send the newsletters registered in the site until you launch the send_newsletter command.
$ python manage.py send_newsletter
This command will launch the newsletters who need to be launched accordingly to the credits of the SMTP server of the newsletter. That’s mean that not all newsletters will be expedied at the end of the command because if you use a public SMTP server you can be banished temporarly if you reach the sending limit. To avoid banishment all the newsletters are not sended in the same time and immediately.
So it is recommanded to create a cronjob for launching this command every hours for example.
You could retrieve the last sources from http://github.com/Fantomas42/emencia-django-newsletter and running the installation script
$ python setup.py install
or use pip
$ pip install -e git://github.com/Fantomas42/emencia-django-newsletter.git#egg=emencia.django.newsletter
For the latest stable version use easy_install
$ easy_install emencia.django.newsletter
Then register emencia.django.newsletter, admin, contenttypes and tagging in the INSTALLED_APPS section of your project’s settings.
INSTALLED_APPS = ( # Your favorites apps 'django.contrib.contenttypes', 'django.contrib.admin', 'tagging', 'emencia.django.newsletter',)
Add these following template context processors if not already present.
TEMPLATE_CONTEXT_PROCESSORS = ( 'django.core.context_processors.auth', 'django.core.context_processors.i18n', 'django.core.context_processors.request', 'django.core.context_processors.media', 'emencia.django.newsletter.context_processors.media',)
In your project urls.py adding this following line to include the newsletter’s urls for serving the newsletters in HTML.
Note this urlset is provided for convenient usage, but you can do something like that if you want to customize your urls :
url(r'^newsletters/', include('emencia.django.newsletter.urls.newsletter')), url(r'^mailing/', include('emencia.django.newsletter.urls.mailing_list')), url(r'^tracking/', include('emencia.django.newsletter.urls.tracking')), url(r'^statistics/', include('emencia.django.newsletter.urls.statistics')),
You have to make a symbolic link from emencia/django/newsletter/media/ directory to your media directory or make a copy named edn, but if want to change this value, define NEWSLETTER_MEDIA_URL in the settings.py as appropriate.
Don’t forget to serve this url.
Now you can run a syncdb for installing the models into your database.
It’s not recommended to use SQLite for production use. Because is limited to 999 variables into a SQL query, you can not create a Mailing List greater than this limitations in the Django’s admin modules. Prefer MySQL ou PgSQL.
A Buildout script is provided to properly initialize the project for anybody who wants to contribute.
First of all, please use VirtualEnv to protect your system.
Follow these steps to start the development :
$ git clone git://github.com/Fantomas42/emencia-django-newsletter.git $ virtualenv --no-site-packages emencia-django-newsletter $ cd emencia-django-newsletter $ source ./bin/activate $ python bootstrap.py $ ./bin/buildout
The buildout script will resolve all the dependancies needed to develop the application.
Once these operations are done, you are ready to develop on the project.
Run this command to launch the tests.
Pretty easy no ?
