Hi, just found out small problem with Rails 2.1.

I have a question about the acts_as_commentable plugin. In the instructions it says to use hidden fields to pass the model type and model id. This is somewhat confusing me. I am trying to add comments to a user object and am not sure how to specify the model type.

Thought I''d post this in case it''s of use to anyone. Maybe even a recipe? It''s just some simple helpers to show AIM status on a webpage. I searched before coding it, and didn''t find anything similar.

Well, I''m working on adding a new type of user (organization) to my application, using a different database table than the standard User table (in the end, I think it works out being easier to deal with than creating another column in the original User table for account type). However, I''m running into a user registration problem. I can register both types of users fine,

In my daily development, I migrate back and forth between versions, and often do: rake load_fixtures... ... in order to populate my development database with fun data. Now, with any HABTM relationship, there are failures, as there is no way to say "which" fixtures to load first. Within an actual functional or unit test case, you could simply load them in the proper order, but
