RedCloth + Ajax problem

I’m using RedCloth and am trying to update a div (id=‘page_content’)
from an ajax link. The problem is that when the element is updated it
inserts the content twice and contains all kinds of ajax code, newline
and tab characters with the content. Here is the link:

link_to_remote “Exhibitions”, update => ‘page_content’, :url =>
{ :controller => ‘pages’, :action => ‘ajax_link’, :page_name =>
“exhibitions” }, :loading => “‘ajax-loader’)”, :loaded =>

the ajax_link action is:

def ajax_link
@page = Page.find_by_page_name(params[:page_name])
respond_to do |format|
format.js { }
format.html { render :action => ‘show’ }

and the ajax_link.rjs is:

page.replace_html :page_content, :partial => ‘page_content’, :object
=> @page

Although if I change the ajax_link action to the following the div is
updated correctly:

def ajax_link
@page = Page.find_by_page_name(params[:page_name])
respond_to do |format|
format.js { render :text => “#{
(@page.page_content).to_html}” }
format.html { render :action => ‘show’ }

Thanks for any help,


If you’re using link_to_remote to call an action which has an RJS
you need to remove the “update => ‘page_content’,” argument in
link_to_remote. If you specify :update, link_to_remote expects to get
some HTML with which to replace that element of your DOM.

When you leave that off, link_to_remote looks for JavaScript (which is
RJS returns) to then execute on the client-side. That executed
then produces the HTML and decides where to put it.

Check out this thread for a (probably) more lucid explanation:

Thanks for the help Ryan, works great.
