Chat for Kotti?

[Richard Prosser]

I am building (I hope) a custom chat server for an online gaming service and Kotti looks promising as a base platform. I have already explored Django, Mezzanine, Wagtail and Flask but all have their shortcomings as far as I am concerned; the Django applications are not flexible enough and Flask lacks a decent TinyCME implementation. I am surprised that there isn't a Flask-based CMS in fact.

Kotti does have some appeal but I am being lazy here as I don't want to spend a lot of time exploring it and then encounter another dead end, so I would appreciate answers to the following, please:

• How readily could a chat facility be implemented? I expect that I would be able to modify something like Flask-SocketIO-Chat to suit but I am not yet familiar with the Kotti infrastructure.
• Which server would be required in that case? Gevent/Eventlet?
• I presume that it would be possible or even easy to show a list of documents (pages) but I can't see anything in the documentation about that. I guess that kotti_blog would be useful.
• How would I form a URL 'section' like <domain>/games? Is that just a document?
• Is it easy to integrate Pyramid add-ons?

If Kotti meets my needs then I may well help with a conversion to Python 3 later on, as I prefer to use that.

Thanks ...

I've not used it, but assuming the docs are correct https://gevent-socketio.readthedocs.io/en/latest/ should be easy to integrate into any Python WSGI App.

The above would require gevent.

documents (pages) but I can't see anything in the documentation about that.

useful.

That's indeed very easy with Kotti. You'd basically

1. construct a SQLAlchemy query that returns the documents you want to show in a view:

   from pyramid.view import view_config
   from kotti.resources import Document

   @view_config(name='myview', renderer='mytemplate.pt', …)
   def myview(context, request):
   documents = Document.query.filter(<whatever your criteria are>)
   return {'documents': documents}

2. and then iterate over those in mytemplate.pt:

   <li tal:repeat="d documents"><a href="request.resource_url(d)">${document.title}</a></li>

- How would I form a URL 'section' like <domain>/games? Is that just a
document?

That'd be an arbitrary Node of any type in your content tree, for example a document.

- Is it easy to integrate Pyramid add-ons?

Kotti is plain Pyramid. Therefore you can use any Pyramid add on as you would in any other Pyramid application.

If Kotti meets my needs then I may well help with a conversion to Python 3
later on, as I prefer to use that.

That'd be great. In fact all the base work is done already (no dependencies without Python 3 compatibility). It just hasn't been done yet, because of missing time.

HTH,

Many thanks Andreas - that all looks useful.
