inside Rails source, at
http://github.com/rails/rails/blob/master/activerecord/lib/active_record/relation/query_methods.rb
I found a lot of calls to:
relation = clone
I can understand where id the "relation" call, but... how about
"clone"
?
Perhaps "clone" comes from Ruby1.9-Kernel, but I am not sure.
And github color it in blue, like a class...weird...
def where(opts, *rest)
relation = clone
if opts.present? && value = build_where(opts, rest)
relation.where_values += Array.wrap(value)
end
relation
end
Can somebody explain this "clone" ? Where it come from ?
Thanks
