Rails - May 2011 - undefined method `model_name' for NilClass:Class in a form_for

Hi! I know that there are other topics about this issue, I read them and
I''m always blocked. Here is the error message:

undefined method `model_name'' for NilClass:Class

Extracted source (around line #30):

27:
28: <h2>Add Translation</h2>
29:
30: <%= form_for @new_trad do |f| %>
31:     Locale: <%= f.text_field :locale %>
32:     Key : <%= f.text_field :key %>
33:   Value : <%= f.text_field :value %>

The new method in TranslationsController:

  def new
    @new_trad = Translations.new
  end

Tell me if other informations are needed.
Thanks in advance!

ps: Sorry for my bad english :)

This means that the @new_trad object is probably nil.

Just a guess, but you might want:
   @new_trad = Translation.new

If that''s not it, I''d recommend checking out the guides on
debugging
and put a breakpoint in the view.

No, it''s Translations and I forgot to tell that it''s not an
ActiveRecord
model.

Right... so the form_for stuff won''t work then, unless you add all the
methods it needs that a "normal" model would inherit from AR::Base (or
probably won''t work at all - use a form_tag instead...)
