Hi, I would like to know if it’s possible with the mental branch to have a category / tag attached to an article. I made a search and it seems that a ticket corresponding to this feature has been closed. I also read on a previous subject that mephisto (at the moment) is better suited for a weblog with such category feature. But I tried to install mephisto without success (I use sqlite3 as the DB). Radiant works and I like it and I prefer not to change. Thanks for any help. ---

You’d be better off with Mephisto in this case. Content management in Radiant is plain hierarchical (tree - based). However, it has a neat extension system now and, if you pull up your sleeves and have some experience, you could make a plugin for yourself that adds category select to the admin interface and a couple of handy Radius tags. You can also resort to some sort of a clever hack. With categories you’re basically trying to make some content appear in multiple places, right? Well, if you could hack the Page model to have multiple parents instead of just one, you could easily achieve this goal. ---

I’m just discovering Radiant and I’m a bit lost with behaviour, plugin and extension. I understand that behaviour will be deprecated with the 0.6 release. But what is the difference and relationship between an extension and a plugin ? I found the following How Tos : - “How To: Create Global Tags in a Plugin”- “How to Write an Extension (work in progress)” But I still don’t know how to link all the things together. CM. ---

Errm I interchanged the two terms in my sentence, which wasn’t right. I meant extension. Plugins in Radiant are like general Rails plugin which can add functionality, monkeypatch existing stuff and so on. For instance, adding Radius tags is done with plugins, while admin interface hackery is in extensions. ---

When the 0.6 is expected to be released ? I suppose that there will be some release notes indicating what are the deprecated features and what are the new way for doing things. I’m a bit lost as the How-Tos seems to mix deprecated features (e.g. behaviour) and new features (e.g. extension). Is it possible to tag How-Tos with the version of Radiant it is applicable (e.g “deprecated in 0.6”, “since 0.6”, …). For example, in the “Define Global Tags” How To, there is a reference to the app/models/page\_context.rb app/models/page\_context.rb but that file from the mental branch doesn’t look like in the How To. Thanks in advance. CM. ---

The use of Rails plugins for this purpose is deprecated. Behaviors have been merged into the Page class in 0.6. You can still do the same things, but you inherit from the Page class instead of inheriting from Behavior::Base. – John L. [http://wiseheartdesign.com](http://wiseheartdesign.com)
