Rails - Sep 2006 - accessing validates_... , :message => 'something'

Hi,

i have a validates_something_of_something method in my User model...i 
added a :message => "you need to abcd" to the validation method,
but
when i try to access it through the <%= error_messages_for "user"
%> it
doesn''t give me any output...

i was wondering whether there was a way to access all of the (:message 
=> string) methods that are collected from the validation methods in the 
model; even building my own error helper or something (from the 
validates_abc, :message => string) to shape it to my own liking...where 
do i start from ?

?

many thanks...

I do believe your supposed to pass in the i-var, not a string or symbol:

<%= error_messages_for @user %>

You can also loop through the error messages yourself this way:

@user.errors.each_full_messages do |message| stuff; end

String.  At least the source handles strings; maybe symbols too, I''m a
bit fuzzy on that.  Note line 105.

 # File vendor/rails/actionpack/lib/action_view/helpers/active_record_helper.rb,
line 103
103:       def error_messages_for(object_name, options = {})
104:         options = options.symbolize_keys
105:         object = instance_variable_get("@#{object_name}")
