The following SQL:

left join users u on u.id = a.user_id
left join genres g on g.id = u.genre_id
where g.name = 'Acoustic'
is the equivalent to (which works):
Video.find(:all, :conditions => ['genres.name = ?',
'Acoustic'], :include => {:artist => {:user => :genre}})
However, I know that the rails 3 active record query uses
the .where()
clause. How can I convert the above to something like:
Song.where({:genre => 'Acoustic', :include => {:artist => {:user
=> :genre}}}) <==== Does NOT work
Song.where({ :genre => 'Acoustic' }).includes({ :artist => { :user =>
:genre }})
I think that's going to try to "WHERE medias.genre = 'Acoustic'"
Perhaps:
.where(['genres.name = ?', 'Acoustic'])
(guessing that both Song and Video are STI subclasses of Media or else
you've omitted some structure that might affect the answer(s) that
you'll receive)
