I have a Model which has a belongs_to association with another Model as follows
class Article
belongs_to :author, :class_name => "User"
end
If I wanted to find all articles for a particular genre ordered by author I would do something like the following
articles = Article.all(:includes => [:author], :order => "users.name")
However if Article happens to have two references to User how can I sort on :author?
class Article
belongs_to :editor, :class_name => "User"
belongs_to :author, :class_name => "User"
end
I have tried
articles = Article.all(:includes => [:author], :order => "users.name")
#=> incorrect results
articles = Article.all(:includes => [:author], :order => "authors.name")
#=> Exception Thrown
