uri = session[:original_uri]
        session[:original_uri] = nil
        render (uri || { :action => :index })

is it possible?

Thanks!

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


        if @post.save
          redirect_to :action => :index, :id => @post.id
        else
          params[:not_saved] = true
          render :action => :index
        end
  end

If I redirect_to then the error_messages_for ''post''
won''t be shown
anymore. Any workarounds?

Thanks!

Mmm...well I have the index page. And when a user clicks "new"
(:action
=> :new), a table slides_down with a form for the Post model in the 
index page. There''s no ''new.html.erb''. Then when a
user submits (:action
=> :save_requirement), it is suppose to redirect_to :action => :index if 
saved successfully. There is no ''save_requirement.html.erb'' so
I need to
render something otherwise I get the ''Missing Template'' error
if the
Post fails to save. Since my form was presented through ajax on my index 
page, I need to display my error messages for the unsuccessful Post on 
the table that slid_down in the index page that holds the Post form. 
Therefore, I have to render :action => :index

At least, that''s the only way I''ve managed to do it. There is
one bug I
found with this method: the url stays the same
''/save_requirement'', when
I don''t want that there anymore if it was unsuccessful.

Hope that''s clearer,

thanks
