I am having trouble with validation and user-friendly error messages when I create a new "Spot" and an associated (has_many) "Title".
I have the following models:

First, the title is being validated, which is good, but I don't have to include a validates_associated call in the Spot model like I would if this was a has_one relationship. Why is that?
Second, when there is an error in the title field, error_messages_for (:object => [@spot.titles[0], @spot]) displays two errors, the first one is what I expect "The Title cannot be blank." but I also get an additional error "Titles is invalid." This error is part of the @spot object. I would like to be able to remove this message, because it is a duplicate, and because I don't know where to change the verbiage to something more user friendly.
Active Record does automatic internal validation of has_many associations. You can turn it off by putting
def validate_associated_records_for_titles() end
after the has_many call. You can then add your own validates_associated call with your own error message. Call validates_associated with :message => nil if you want no error message displayed for the parent object.
