Hi:

Passing child virtual attribute validation error to parent…  
in case of nested attributes.

So, I have a Parent Model say ‘Parent’.  
Nested Attributes it accepts for Child say ‘Child’

Now suppose there is a validate method in ‘Child’

and it has something like self.errors.add\_to\_base(“some message”).

How do you make sure that Parent gets this?

I thought it will be auto copied to Parent as in other normal class  
macros like validates\_presence\_of.

However, in this case I am loosing the message display from Child to  
Parent for this error.

Is there a manual copy method for Child to Parent?

This is for a Virtual Attribute added in Child, but just doing  
self.errors in Validate of Child, shouldn’t it be copied to Parent  
directly?

Thanks for any clarifications here.
