I'm not sure what you mean by "the Address model validates before the
values are updated in the Account model" - can you extract some model
code to illustrate?

It occurs to me, that if an Address can be different depending on the
model it's associated with, the validation check needs to move to the
associated model maybe. How about adding something like this to
Account:

validates :valid_address if :address

private
def valid_address
errors.add_to_base "address is not valid for one reason or
another" unless address.valid_for_account
end

... and this to Address:

def valid_for_account
return true if self.post_code.nil?
return true if self.some_other_validation_check_returns_true
return true if self.etc
end

You could merge the Errors from Address into Account, rather than just
adding a generic one to base, to display "nice" messages to the user.
