What would be the best plugin for a simple Category feature of a Rails Application?

Question

Basically it will be used for categories of some articles. So the hierarchy probably only has about 5 levels max. and the hierarchy structure won't be changed frequently. Also it would be good if the plugin itself is easy to extend because I might need make categories associated with users.

I am aware that there are some act_as_tree-like plugins around, such as acts_as_nested_set, awesome_nested_set, etc. But they look kinda heavy to me(I might be wrong here). Which one is the best one for this simple feature?

Answer 1

And why not using the plugin you mentioned, act_as_tree. It's simple enough to handle what you are willing to do.
