How to retrieve attributes from HABTM?
We have tables Users and Communities linked by has_an_belongs_to_many. The join table Communities_Users has additional fields [ is_active, is_blocked, join_date] etc. These are populated using @user.push_with_attributes(:is_active => true,...). Later on how do we update or retrieve the attributes in the link table for a given user or a community with doing it explicitly using SQL? Thanks,

I did read http://backgroundrb.rubyforge.org/ and Ezra''s blog of course, but I still have a few questions. I made a simple upload form (as a test) that is submitted to the "upload_song" action. def

So far one can login as a member and from this point on one has

Hey all, i''m rather new to rails and was curious if ActiveRecord implemented anything like is_active where the delete functions would just mark records as inactive, vs deleting rows. (similar to created_at, etc). I need a history of transactions, and this is how I would code in other languages. Any advice? Is there are smarter way to implement this? Thanks in advance! -- Posted via
