You can't use a join table with a one_to_many association. Use a
many_to_many association instead. If you want want to destroy children
when the parent is destroyed, maybe something like
class ParentClass < Sequel::Model
many_to_many :children
def before_destroy
cs = children
remove_all_children
cs.each{|c| c.destroy}
super
end
end
Thanks,
