Rails 3 - Creating a comment and then returning the Partial with JUST the new comment -

Here I have the flow ...

First of all, jquery posts new comment on the server:

$ Post (this.action, $ (this). Serialize (), blank, 'script');

Then in comment controller:

  def make @comment = lots of stuff going here but this works ... if @ comment .save flash [: notice] = "Successfully commented." Response_to do | Format | Format.js end end  

OK and this is where I got stuck, then create.js.erb:

  $ (" Cmtbox ​​"). Html ("& lt;% = escape_javascript (render: partial = & gt;" comments / comment ")%>);  

and partial:

  & lt; Div class = "cmtbox" id = "comment_  & gt; & Gt; & Lt;% = comment.content% & gt; & Lt; / Div & gt;  

Where I am stuck, I am making a partial call to create.js.erb ... how will I pass, which needs partial populations? I get an error now: "Id has been called for zero, which can be accidentally 4 - If you want to actually identify the zero, then use the object_id

thanks!

You should use:

  render: partial = & gt; @ comment  

or

  render: partial = & gt; "comments / comment" ,: object = & gt; @ comment  

or

  render: partial = & gt; "comments / comment" ,: Local = & gt; {: Comment = & gt; @ Comment}
