Wow! A whirlwind of hacking has produced the first version of the comment system that i am going to use on this Potlatch blog, a Google App engine powered blog. The comment system is built as a proof of concept for Demisauce, the open source project i have been working on. The core idea of Demisauce is an open source set of web services that allow you to add functionality to your app. This service is mostly a javascript service that you embed on your app, allowing comments on anything. The other Demisauce services so far are XML services and html. This service (comments) is not better than the other comment systems out there (Disqus.com is very nice, and obviously Wordpress.com has comments for all blogs at Wordpress), but it is able to be installed and run behind a corporate firewall. I am thinking of using it for some applications at work to comment on just about anything, not just blog posts. Think of comments on images (flickr), or commenting on a purchase order, or requistion, or request to hire someone that are in corporate systems.
The configuration Page with the javascript you would need to copy, and embed in your pages. Also shows comments by this user.
Here is an actual view of the comments in a blog, showing comments, comment box, login etc.
Here is a view by a user not logged in (uses google Authentication or you can create an account).
This shows a user that has clicked on "Logon" but is already authenticated.
These are the Logon Comments
The features
- Google Authentication for Users (optional)
- Gravatar Icons
- Native authentication for users (if Not using Google)
- Configuration tools to setup javascript for your app
The application is built on the Python, Pylons base of Demisauce, but the core of the presentation is Javascript/Jquery. You can get the code at Demisauce on google code or get this blog code at Potlatch Blog on Github.
Although Comment systems are not the services I wanted to build first for Demisauce, I decided it is a great example for a service that combines Javascript, Data/Persistence, Widget/Embedding. I am planning on enhancing this a bit more, possibly doing a Django Book style pop-up comment system. Also, been wanting to enhance the help system some more, which uses the content management system which although not fancy is usable. If anyone else has some ideas on what they would like to see first I would love to hear them.
