Will paginate breaks with :select and :join in mysql

Reported by Jeff Dean | June 23rd, 2007 @ 09:28 PM

This is actually as much a MySQL bug as it is a will_paginate bug, but since it's easier to change will_paginate...

The following statement

  :joins=>"inner join forums on posts.forum_id = forums.id", 
Produces the following sql
@@@SELECT count(posts.*) FROM posts@@@ which is invalid in mysql

However, if you just put

Post.paginate(:joins=>"inner join forums on posts.forum_id = forums.id", 
it picks up the id from the forums table, not the posts table.

Is there a way you could add a ":select_for_count" parameter?

I suppose you could get around this by adding your own total_entries parameter, but that seems less dry than capturing it in the finder
