Hi, guys,
I''m in the midst of moving an app from rails 2.3.8 to rails 3.0.9.

Active Record Query
A course has many lessons and a lesson has many topics.
A topic can have a recipe or vice versa, a recipe has many topics
(optional).
I need to come up with the most efficient way of querying the database
to find those topics belonging to a course (via lessons of course) which
have a recipe (in other words recipe_id is not null for this topic
record).
Simple but challenging :)
Thanks for your

Devise confusing routes
I had a similar problem yesterday.
I would go to the root of my site and I would get a Too Many Redirects
message. It seems like there was an infinite loop. After struggling for

But now, when I want to create a New User, it''s redirecting me to the
Sign In screen. Seems like I didn''t fix the problem completely.
