I have a form that accepts comments and adds them to a list without refreshing the page.

This is the html:

\<div id='aremark'\> \<%= render :partial =\> 'comment' %\> \</div\>

&nbsp;&nbsp;\<% remote\_form\_for :comment, :url=\>story\_comments\_path(@story), :html =\> { :id =\> 'comment' } do |form| %\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<h5\>\<label for="login"\>Make a comment:\</label\>\</h5\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<div id="body"\>\<%= form.text\_field :body %\>\</div\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<p\>\<%= submit\_tag 'Comment' %\>\</p\>

&nbsp;&nbsp;\<% end %\>

The form works i.e on refreshing the page the new comment is seen in the comment partial.

From comments\_controller

def create &nbsp;&nbsp;&nbsp;&nbsp;@story = Story.find(params[:story\_id]) &nbsp;&nbsp;&nbsp;&nbsp;@story.comments.create params[:comment] &nbsp;&nbsp;&nbsp;&nbsp;flash[:notice] = "Thank you for commenting" end

This is create.rjs

\<script\> aremark = page.getElementById("aremark") page.replace\_html('aremark', :partial =\> "content") \</script\>

This was working then didn't. I don't know what I did to break it. Can anybody see where I am going wrong?

It should read

I want a form that accepts comments and adds them to a list without refreshing the page.

This is weird - if it's an rjs file you don't want script tags - an rjs file only contains ruby.

So I strip it down to

page.replace\_html('aremark', :partial =\> "content")

Still won't work without refreshing the page

In the log I get

ActionView::MissingTemplate (Missing template comments/create.erb in view path app/views):

Does that help anyone to explain

Hello, Shouldn't you be doing page.replace\_html from inside your controller and using your rjs page as a paramater passed to page.replace\_html??

I think the log is telling you that your request found def create....but without making def create render something other than create.html.erb, won't the controller be looking for that instead of your rjs template?

I don't understand, how would it find the rjs and if the page.replace\_htm is in the controller what would it contain?

I think this is the problem but I don't know the solution. Surely in the absence of create.html.erb it should find create.rjs but doesn't???
