# what breaks

<% blogs = @story.user.blogs %>

# with:

Cannot find the child_model Blogadmin for User

# the relationship in User
# doesn't work
has n, :blogadmins
# this doesn't work either
#has n, :blogadmins, :class_name => "Blogadmin", :child_key => [:user_id]
has n, :blogs, :through => :blogadmins

# the relationship in Blogs
        has n, :blogadmins
        has n, :admins, :through => :blogadmins

# the blogadmin class
