Add Webmentions to blog posts

[philgyford]

And to link posts? Or would that have to go into django-ditto?

• https://indieweb.org/Webmention
• https://github.com/easy-as-python/django-webmention (receive only)
• https://github.com/beatonma/django-wm (send and receive? Requires celery and rabbitmq)
• https://github.com/bear/ronkyuu (send and receive)
• https://github.com/Ryuno-Ki/webmention-tools (send and (maybe?) receive via webmention.io)

Tasks

• [x] Create MentionableMixin model:
• [x] Create IncomingWebmention model:
  • time_created (from TimeStampedModelMixin)
  • time_modified (from TimeStampedModelMixin)
  • GenericForeignKey fields to link to Post (or whatever)
  • source_title
  • source_url
  • target_url
  • is_visible boolean
  • is_deleted boolean (for if the source was 410 or 404 at last check)
  • validated boolean (if both source and target URL have been verified to exist, as in django-wm)?
  • time_deleted (ditto)
• [x] Create OutgoingWebmention model:
  • time_created (from TimeStampedModelMixin)
  • time_modified (from TimeStampedModelMixin)
  • GenericForeignKey fields to link to Post (or whatever)
  • source_url
  • target_url
  • target_endpoint_url
  • status - waiting, unreachable, target error, endpoint error, ok
  • response_code
• [x] Add allow_incoming_webmentions and allow_outgoing_webmentions to Post (or any model that we have them on?))?
• [ ] OutgoingWebmentionStatus model, as in django-wm?
• [x] Generate outgoing mentions when a Post (etc) is saved
• [x] Add a 'Webmentions enabled' global settings (incoming and outgoing)
• [x] And/or a setting to set whether incoming Webmentions are automatically approved or not?
• [ ] Create a /webmentions endpoint
• [ ] Create a middleware to add webmention endpoint to HTTP headers, as in ronkyuu and django-wm?
• [ ] Management command for sending any unsent webmentions
• [ ] List valid, public incoming mentions on the end of a Post
• [ ] Show count of incoming mentions in list view of Posts

So django-webmention only handles incoming webmentions.

django-wm requires RabbitMQ and Celery.
