RDoc and documenting model attributes?

I’d like to “rdoc” my rails application, and have rdoc also pick up the model attributes (i.e. the columns in my database tables), with the ability for me to comment them as well (i.e. "what is this column for?).

Is this something that rdoc, or rdoc + some other tool/technique, can do?

Thank you,


You could get something basic using the annotate_models plugin, then
you could customize it at will.
