Need help regarding RESTful and Ajax Form

I'm trying to create an ajax form but I'm a little confused on the syntax I should use for REST.

I recently created a comments model which belongs to poems, and poem has many comments.

I set up the routes like so:

[code=ruby] map.resources :poems do |poems|    poems.resources :comments end [/code]

My Comments Controller [code=ruby] class CommentsController < ApplicationController   def new     @comment = Comment.new   end

  def create     @comment = Comment.new(params[:comment])

     respond_to do |format|         if @comment.save           flash[:notice] = 'Poem was successfully created.'           format.html { redirect_to comment_url(@poem, @comment) }           format.xml { head :created, :location => comment_url(@poem, @comment) }         else           format.html { render :action => "new" }           format.xml { render :xml => @comment.errors.to_xml }         end       end   end end [/code] But I'm rather confused on what I should be doing to create an ajax form for comments, while viewing a poem.

poem show.rhtml [code=ruby] <p><% form_remote_tag(:update => "comments",                    :url => { :action => :new },                    :position => "top" ) %>     New Comment:     <%= text_field_tag :new %>     <%= submit_tag 'Save' %>   <% end_form_tag -%></p> [/code] I did something like that, but I don't think that's right.

If anyone could point me in the right direction, I'd appreciate it. Thanks!

>                 New Comment:
>                 <%= text_field_tag :new %>
>     <%= submit_tag 'Save' %>
> 
>   <% end_form_tag -%></p>

this might work for you (if you’re using 1.2 or edge):

<% remote_form_for :comment :url => new_comment_path(@poem) do |f| -%> <%= f.text_field :new -%> <%= submit_tag ‘Save’ -%>

<% end -%>
