...returns params to the controller, empty fields appear to be returned as blank, not nil. so what''s the point of an :allow_nil=>true setting on a validation? it fails because blank is not the same as nil. i would expect either returned empty fields to be nil, or :allow_nil to really be :allow_blank. otherwise i have to do a search through params every time i do a create/update to convert blank to nil. totally unrailslike. someone straighten me out please... thx - mike --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Gr...

Hi, since rails 2.2 doesn''t work with gettext anymore I decided to use a gettext dummy method until the gettext team relases a working version for rails 2.2. My application doesn''t need any i18n support right now and this way i figured it would be very easy to integrate gettext later. Just setup the plugin and go. So I need a method called _ which is available in alle models,

So a lot of Rails apps (mine included) have multiple validations on a single attribute. For example: on the password field, validating that it is (a) not blank, (b) matches the confirmation, (c) is at least X characters long, and (d) contains at least 1 alpha and at least 1 numeric character. The problem is: if that field is blank, the default errors shows all four. That''s a little
