Rails - Apr 2006 - Validates_presence_of in ActionMailer model

Hi all,

I want to submit the content of a form by mail.
I don''t want to save it into a DB.

How can I validates the content of this form with validates_presence_of ?

Thank you.

Damien

validates_presence_of is a method defined in ActiveRecord, so if you 
don''t have an active record object, you dont get the method.  You may 
have to do manual validation of data that has no model.

May I ask why not? Does your application not use a database at all? 
Storing the data in the database is a nice backup and you can still send 
the email... trusting that the email gets delivered isn''t as safe. ;-)

You need an ActiveRecord object in order to use the validations in Rails.

Rick Olsen has a rails weenie entry where he defines the columns in an 
ActiveRecord object without a database table... which gives you access 
to those validation methods. I did something similar for a 
proof-of-concept plugin for interacting with stored procedures... to 
validate parameters before executing the procedure. I''m sure that this 
same concept could be used in this case.

Here is the post from Rails Weenie:

Hope that helps!
