Hey people, I was wondering whether it''s possible to validate a text_field_tag which has nothing to do with the actual object being created?

For example, I call a Vlaidation method onsubmit with a form when somebody creates a new object.

Hey, both are actually pretty good approaches I think but I was hoping I could use that could use error_messages_for for the text_field_tag... that''s probably not the case? If I was using "if not_good(params..." I''d need to display it differently. It''d be extremly handy if I could just add an error to error_messages_for using "if not_good(..." -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

But the text_field_tag has nothing to do with the @record so it wouldn''t help if I was checking if the @record is valid, right? tony wrote:> you could also try...-CFSAjdWTiPz1P9xLtpHBDw@public.gmane.org_valid? > > which will validate w/o saving > > On Mar 17, 11:00�am, Frederick Cheung <frederick.che...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>-- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Heinz,
If you''re looking to invalidate the object based on this non-member
field,
you could use
ActiveRecord.Errors.add_to_base()
e.g. @record.errors.add_to_base("Invalid unpopple value")
Then check validity with @record.errors.empty?
Note that @record.is_valid will still return true (unless you override
invalid? for the class).
Hope that helps,
James.

since your text field tag isn''t part of the model, you could instantiate the object with the value from the tag and then call is_valid and check the errors variable if you want the message. else you''ll have to write your own validation methods On Mar 17, 3:15 pm, Heinz Strunk <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> But the text_field_tag has nothing to do with the @record so it wouldn''t > help if I was checking if the @record is valid, right? > > tony wrote: > > you could also try...-CFSAjdWTiPz1P9xLtpHBDw@public.gmane.org_valid? > > > which will validate w/o saving > > > On Mar 17, 11:00 am, Frederick Cheung <frederick.che...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> > > -- > Posted viahttp://www.ruby-forum.com/.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
