如何将SQL转换为Arel？

Question

有没有办法将MATCH和AGAINST零件转换为Arel？

我在Arel源代码中找不到任何关于它的东西。

我用Rails 3

SELECT gigs.time, gigs.channel_id, gigs.song_id, gigs.id, 
    MATCH (songs.title) AGAINST (?) AS song_score, 
    MATCH (artists.name) AGAINST (?) AS artist_score 
    FROM songs 
    INNER JOIN artists ON artists.id = songs.artist_id 
    INNER JOIN gigs ON gigs.song_id = songs.id 
    WHERE MATCH (artists.name) AGAINST (?) OR 
    MATCH (songs.title) AGAINST (?) 
    HAVING (artist_score + song_score) > 0 

Answer 1

AFAIK没有阿雷尔MATCH AGAINST实现。我的猜测是因为它不是纯SQL，而是针对MySQL。
