django-wm 1.0.2

Webmention support for any Django model.

Mentions

Mentions lets you add Webmention functionality to any Django model with minimal setup. There is an implementation running at https://django-wm.dev/ with source code available here.

Installation

pip install django-wm

Setup

Celery

Mentions uses Celery and RabbitMQ for running tasks asynchronously. If you do not use them already you will need to set them up first.

System:

sudo apt install rabbitmq-server

# Create user for celery service and make sure it can access your database
# e.g:
sudo useradd -N -M --system -s /bin/bash celery
sudo usermod -a -G www-data celery

# Run celery
sudo -u celery env/bin/celery -A projectname worker &

Project:

Add celery.py to your root project. For an example implementation see celery.py from the example project.

Project code

1. Root project settings.py:

   • Set DOMAIN_NAME:

     DOMAIN_NAME = 'your.url.here'  # e.g. 'django-wm.dev'
     

   • Add “mentions” to INSTALLED_APPS:

     INSTALLED_APPS = [
         'django.contrib.auth',
         'django.contrib.contenttypes',
         'django.contrib.flatpages',
         'django.contrib.sites',
         ...
         'mentions',
     ]
     

   • Add :code:’mentions.middleware.WebmentionHeadMiddleware’ to MIDDLEWARE:

     MIDDLEWARE = [
         ...
         'mentions.middleware.WebmentionHeadMiddleware',
     ]
     

2. Root project urls.py

   urlpatterns = [
       ...
       path('webmentions/, include('mentions.urls')),
   ]
   

3. Include MentionableMixin in the model(s) you want to support webmention functionality.

   IMPORTANT: Any models that include the mixin must also implement all_text and get_absolute_url methods:

   from mentions import MentionableMixin
   ...
   
   class MyModel(MentionableMixin, models.Model):
       ...
       def all_text(self) -> str:
           return f'{self.introduction} {self.content}'
   
       def get_absolute_url() -> str:
           return reverse('app.views.name', kwargs={'slug': self.slug})
   

4. Update database tables:

   python manage.py makemigrations
   python manage.py migrate
   

Optional Settings

Add these keys to your project settings.py to alter default behaviour.

WEBMENTIONS_AUTO_APPROVE = bool (default: False)

• True: Received webmentions are automatically approved and may be publicly visible.
• False: Received webmentions require manual approval before they can be made public.
