That did the trick! Thanks!
But, I am sorry I did not get your explanation. Forgive me, I am very
new to Ruby and Rails. Could you please explain why it didn't work
before, and why it worked your way?

Also, in my controller, I'd like to call the parent controller's
method to format my json in a certain way...So instead of this:
respond_to do |format|
format.json { render :json = @projects.to_json(:include =
[:apps]) }
end
I'd like to do something like this:
result = nested data

I'm overwhelmed by the syntax in the second line,
self.questions.reject{|q| q.nil?}.all
def needed_questions
self.questions.reject{|q| q.nil?}.all

Go look up the relevant functions (especially reject) in the
documentation.
If your models are set up correctly you can do '@user.questions' for
the collection. You can set up a method or named_scope maybe on the
user model:
def needed_questions
self.questions.reject{|q| q.nil?}.all
end
something like that.

You could either use the find_by_sql method or the :joins method. (As
someone has stated earlier that avoid find_by_sql for performance and

In summary, provide enough :has_many = :through to get to the keying table,
then put it into your :include and :conditions.

Briefly, since you seem to have more experience with raw SQL than ActiveRecord
(better than the other way around!;), try inspect_sql to see
