accessing validates_... , :message => 'something'

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}")
