I got my collection items like this :
hotels = Hotel.where('selection = ?', 1).limit(4)
How can I get all ids of this items without a loop? Can i use something like :
hotels.ids ?
Thank you
What about trying
hotels.map(&:id)orhotels.map{|h| h.id }?They both mean the same thing to Ruby, the first one is nicer to accustomed ruby-ists usually, whilst the second one is easier to understand for beginners.
