It has nothing to do with polymorphism. You’ll want to look into eager
loading for your associations if you want to avoid those queries.

Because activerecord isn’t super smart in this way and doesn’t fill in
associations bidirectionally when they are loaded.

So what’s the solution to that Fred ? I would have to load question also
when I load the subquestion ? That would mean doing a different query
twice
for extracting the same object. Or is there any other way around ?

There isn’t really good solution. There’s a plugin that attempts to
address this (parental_control), or you can fiddle around making ar
believe it has already loaded it. The ar_context plugin can also be
helpful in this context.
You can also make your include load it (ie :include => {:subquestion
=> :question} but that always seems a bit messy.
You also do things semi manually ie instead of referencing
foo.question, collect all the questions into a hash indexed by id and
access your_hash[foo.question_id]

hmm Right… Thanks
