I really like using error_messages_for in my views. In one of my
views, I create a ticket object and a message object, and the message
belongs to the ticket. When I do error_messages_for(:ticket), I’d
like to get any errors on the associated message. Something like:
Two errors prevented this ticket from being saved.
There were problems with the following fields:
Subject can’t be blank (this is a Ticket attribute)
Body can’t be blank (this is a Message attribute)
A Ticket has_many :messages, so right now if the body is blank, I get
a message that says “Messages is invalid.” I was wondering if somehow
I could display the exact error message for the Message in the same
box as the error for the Ticket.
