Rails - Jul 2008 - model error_messages_for

I have this in my form view:

<%= error_messages_for ''post'' %>

I''m not using form_for, just a regular form_tag:
<% form_tag :action => ''save_requirement'' do %>

The error messages do not pop up, any suggestions?

Thanks!

is @post an instance of an activerecord object with some errors?

Yes,

controller:

  def new_requirement
    @post = Post.new
  end


  def save_requirement
      @post = Post.new(params[:post])

      if @post.save
        redirect_to_index("Thank you for your post!")
      else
        redirect_to :action => :new_requirement
      end
  end

In the failure case, you don''t want to redirect; you want to render.
Redirecting triggers a completely new request cycle, with a new
controller instance, and all instance variables are reset to nil. So
@post will be back to being a new Post instance, which will not have
any errors, so no errors will be displayed.

If you render, on the other hand, you''ll just be rendering the
new_requirement template with the existing @post object, which does
have errors.
