Discourse connector
|
||||
===================
|
||||
|
||||
The Discourse connectors detects incoming mails from Discourse and
|
||||
improves them by fetching the content and user data via API.
|
||||
|
||||
Prerequisites
|
||||
-------------
|
||||
The user has to configure the mail interface so that the user's mails
|
||||
can be fetched via Friendica. Then the user has to activate the
|
||||
mailing list mode in Discourse.
|
||||
|
||||
The mailing list mode in Discourse knows two different options:
|
||||
1. Get all posts - including your own. This will create duplicates
|
||||
if you post via Friendica.
|
||||
2. Don't get your own posts. Then you will missing all your posts
|
||||
that you made directly on Discourse. Since you cannot create
|
||||
a new post via this connector (only comments are possible)
|
||||
this is not a good choice either.
|
||||
|
||||
Known problems
|
||||
--------------
|
||||
- You can't create starting posts
|
||||
- Either you don't get your own posts you made directly on Discourse
|
||||
or you do get duplicates for every post you made via Friendica.
|
||||
- Non public categories are currently only working via some workaround
|
||||
without the API, which most likely will cause some content problems.
|
||||
- links to Discourse profiles in the posts are invalid.
