# r.en_title.blank? || r.ar_title.blank? || r.fr_title.blank? || !r.cover_en.exists? || !r.cover_ar.exists? || !r.cover_fr.exists? || !r.insert_en.exists? || !r.insert_ar.exists? || !r.insert_fr.exists? 

Consider incorporating

[:en, :ar, :fr].any? {|lang| r.send("#{lang}_title").blank? || !r.send("cover_#{lang}").exists? }

or define an instance method to call #title(:en)
