exists? should not instantiate a record

Automatic cleanup of spam.

@Jose: i wanted to work on that but I can't reproduce it with

def test_exists_with_scopes
  assert_nothing_raised do
    authors(:david).posts.containing_the_letter_a.exists?(:title => 'Welcome to the weblog')
  end
end

with current Rails' master. This test just passes.

Am I testing it right or is this bug solved?

It seems your test is right. Is Author doing has_many :posts and Post doing belongs_to :author or they are passing additional arguments? Have you checked if that piece of the code I mentioned above is being called?

Thanks for looking into this!

There's an extension on the belong_to :author association but nothing more than that.
Yes the piece of code you mention is being called.
About the published attribute you put in the code, are you sure it is stored at the children level?

Yes, it is at the child level. But I just checked again and found out that my "comments" has a include clause, like this:

class Post
  has_many :comments, :include => :comment_author
end

So it is quite likely that it is this other include that is making it fail?

No luck in trying to reproduce that one unfortunately. :/
