ActiveScaffold is nice to get fastest results in short time but is a pain-on-ass if you try to made more.

In my case, I needed to show in a list some type of documents filtered by the conditions_for_collection method.

def conditions_for_collection
   ['type_document_id in (?)', [12]] #you mean hardcode. I use a number but you can use a variable. 
end

It's works fine, but If you would like to have access to a nested scaffold and be able to see all related document without filtering them, the things go wrong.
I've solved this issue asking if we are in a nested scaffold.

def conditions_for_collection
  unless !params[:nested].nil?
      ['type_document_id in (?)', [12]]
  end
end

It Works now! I hope you enjoy.
