There is a :header\_message option on error\_messages\_for:

:header\_message - The message in the header of the error div. Pass nil  
or an empty string to avoid the header message altogether. (Default:  
“X errors prohibited this object from being saved”).

[http://api.rubyonrails.org/classes/ActionView/Helpers/ActiveRecordHelper.html#M001282](http://api.rubyonrails.org/classes/ActionView/Helpers/ActiveRecordHelper.html#M001282)

You could also monkey patch ActionView::Helpers::ActiveRecordHelper if  
you want to change the default message across the entire application.

module ActionView  
module Helpers  
module ActiveRecordHelper

```
  def error_messages_for_with_message_overrides(*params)
    options = params.extract_options!.symbolize_keys
    options[:header_message] = "My Custom Error Message" unless

```

options.include?(:header\_message)  
options[:message] = “” unless options.include?  
(:message)  
error\_messages\_for\_without\_message\_overrides(params, options)  
end

```
  alias_method_chain :error_messages_for, :message_overrides
end

```

end  
end

Cheers
