What is the best way to validate a field NOT to be the same as another
field? I tried doing this unsuccesfully. Any ideas would be apreciated.
validates_each :fieldx do |record, attr|
record.errors.add attr, ''must be different from fieldy'' if
attr ==
fieldy
end
Thanks in advance,

The thing is if I try your suggestion I get this error: undefined method `fieldx'' for User:Class with this code: validates_each :fieldx do |record, attr| record.errors.add attr, ''must be different from fieldy'' if self.send(attr) == record.fieldy end In the end I had to compare record.fieldx with record.fieldy which is an ugly hack (hard-coding) but it works for this specific case. Though your idea made me see that I had the record object right there. Now that I think about it I could do record.send(attr) == record.fieldy It works! Here''s the final code: validates_each :fieldx do |record, attr| record.errors.add attr, ''must be different from fieldy'' if record.send(attr) == record.fieldy end Thanks for the help, Adrian Madrid François Beausoleil wrote:> > > Adrian Madrid said the following on 2005-09-07 13:38: > >> What is the best way to validate a field NOT to be the same as >> another field?
