Allow associations to be used inside defaults

    • Type: Icon: Bug Bug
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • 8.0.1
    • Affects Version/s: None
    • Component/s: Associations
    • None
    • Minor Change

      Relations are set after defaults, so you can't use any relation method as default value.

      class Band
        include Mongoid::Document
        has_many :songs
        field :name
      end
       
      class Song
        include Mongoid::Document
        belongs_to :band
        field :band_name, default: -> { band.name }
        field :name
      end
       
      band = Band.create(name: "Molejo")
      song = band.songs.create(name: "Cilada")
