How to generate a rails link with an AR validation message

Question

Hi,

I'd like to give a link to the contact us page on failure of a validation. I've tried this to no avail:

validates_acceptance_of :not_an_agency, :on => :create,
:message => "must be confirmed. If you are an agency please #{link_to "Contact Us, contact_path}"

Anyone know how to get past this one?

With Rails 3

you need include ActionView::Helpers::UrlHelper in your Model and define the message like a lambda to be interpret when needed

class XXX < AR
  extend ActionView::Helpers::UrlHelper

  validates_acceptance_of :not_an_agency, :on => :create,
                          :message => lambda {"must be confirmed. If you are an agency please #{link_to "Contact Us", contact_path}"}

end

With Rails 2

it's the same but you need define the :host each time.

class XXX < AR
  extend ActionView::Helpers::UrlHelper

  validates_acceptance_of :not_an_agency, :on => :create,
                          :message => lambda {"must be confirmed. If you are an agency please #{link_to "Contact Us", contact_path(:host => 'http://example.org')}"}

end
