Hi,
Hash conditions (on has_many associations) are ignored when accessing through a HMT.
For example: # class Author has_many :published_posts, :class_name => "Post", :conditions => "posts.body = 1" has_many :published_comments, :source => :comments, :through => :published_posts
Author.find(:first).published_comments # works!
But: #class Autor has_many :published_posts, :class_name => "Post", :conditions => {:published => true} has_many :published_comments, :source => :comments, :through => :published_posts
Author.find(:first).published_comments # doesn't work!
Here is the patch (with tests) to fix this:
