Rails - Apr 2006 - paginate :includes not working as I thought it should

Hello everyone, I have the code below:

paginator_options.merge!({:conditions => ''cities.id = 4'',
:include =>
[:cities]})

@people_pages, @people = paginate :people, paginator_options


There''s a many-to-many relationship between people and cities.

It seemed like before this was working, but now in the sql that''s
generated
the join table isn''t present so that the condition "cities.id =
4" throws an
error. Any ideas?

Thanks,
Daniel
