Hi everyone!

I want to send mail to certain users telling them that a record was  
created, and where they can find it. I tried using after\_create  
:deliver\_notice but the mailer can’t seem to evaluate the created  
object.

For example: People save settings saying “when a new product is added,  
email me”. So, in product.rb, after\_create :deliver\_notice.  
deliver\_notice in mailer.rb fires out the email saying check out the  
new product at [domain.com/products/28-the-new-one](http://domain.com/products/28-the-new-one)… well, is supposed  
to fire it out anyway, but I get an evaluating nil error.

How should I go about this?

## Thanks!

Ramon T.

I think you want to look into using an observer.
