field_error_proc 'error_message undefined method' in rails 3.pre

#4078

I am trying to override the field_error_proc:

ActionView::Base.field_error_proc = Proc.new do |html, instance|
%(#{html} #{instance.error_message}) end

but it throws this error:

ActionView::Template::Error (undefined method error_message' for #<ActionView::Helpers::InstanceTag:0x0000010361b798>)

Has error_message been changed/deprecated?

    it works but outputs safe html instead of the raw version

    ActionView::Base.field_error_proc = Proc.new { |html_tag, instance|
    "

    try to add raw and it doesnt like it..

    I think if you try adding .html_safe on the string output it works, but I am more concerned with getting what was instance.error_message but now errors.on is [] I dont see how to get it?

    I have the same problem:

    undefined method error_message' for #<ActionView::Helpers::InstanceTag:0x40be40c>

    Looking at the code (both Rails-3.0.0.beta and Edge in GitHub) at the bottom of active_model_helper.rb (http://github.com/rails/rails/blob/master/actionpack/lib/action_vie...) you can see that ActiveRecordInstanceTag has not that method defined.

    I have prepared a patch which fixes the omission and includes a test.
