Well, after first thinking "Why not?" I'll offer this (it's only Ruby):
@user.linenumbers.sort_by{|line| line.number}.each do |line|
#...
end
But I'll still suggest:
class User
has_many :linenumbers, :order => 'number'
end
Or perhaps a named scope is OK,
class Linenumber
named_scope :ordered, :order => 'number'
end
@user.linenumbers.ordered.each do |line|
#...
end
