How to use AREL eq() method in a where with joined data

Question

I currently have this scope:

class User

  has_many :inbox_messages, :through => :message_users do
    def unread
      published.where(:message_users => { :sender => false, :trash => false , :deleted => false}).where(MessageUser.arel_table[:read_at].not_eq(nil))
    end

  end
end

And it's working. But I was wondering if there is way to merge the second where into the first one.

If I understand your code correctly, you should be able to do that with

published.where(:message_users => { :sender => false, :trash => false , :deleted => false, :read_at => nil })
