    <p>I'm trying to get some basic ajax working on rails. I have a comon main page, with a banner, sidebar and main area. In the sidebar I have added a dropdown menu and button (clunky I know, but you have to start somehere) to change an attribute of the user's view of the site (the selected network). The idea is that when the network is changed, the AJAX functionality should change the list of sites reflecting the fact that the network has changed. </p> <p>The problem is that when the AJAX code runs, I get the javascript appearing in my browser window, rather than updating the appropriate element</p> <pre><code>try {Element.update("site_list_body", "&lt;-- the correct html appears here --&gt;");} catch (e) { alert('RJS error:\n\n' + e.toString()); alert('Element.update(\"site_list_body\", \"&lt;--same html code here too--&gt;");'); throw e } </code></pre> <p>I've had a look round stackoverflow and google, and despite trying various suggestions, none of them seem to work at the moment. Any help would be appreciated :-)</p> <p>Thanks</p> <p>Steve</p> <p>So (with simplifications) - my main page looks like this</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"&gt; &lt;head&gt; &lt;meta http-equiv="content-type" content="text/html;charset=UTF-8" /&gt; &lt;title&gt;Networks: &lt;%= controller.action_name %&gt;&lt;/title&gt; &lt;%= stylesheet_link_tag 'frontier', 'menus' %&gt; &lt;%= javascript_include_tag :defaults %&gt; &lt;/head&gt; &lt;body id="frontier-network"&gt; &lt;div id="banner" &lt;--banner and menu stuff --&gt; &lt;/div&gt; &lt;div id="columns"&gt; &lt;div id="side"&gt; &lt;-- some other stuff --&gt; &lt;div id="site_list_body"&gt; &lt;%= render :partial =&gt; "shared/network_site_list", :locals =&gt; {:site_list =&gt; @site_list} %&gt; &lt;/div&gt; &lt;div&gt; &lt;% form_for :user, :url=&gt;{:controller=&gt;'users', :action =&gt; :change_network} do |f| %&gt; &lt;-- this is where the dropdown list etc goes --&gt; &lt;/div&gt; &lt;/div&gt; &lt;div id="main"&gt; &lt;%= yield :layout%&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>The javascript .rjs.js file contains page.replace_html("site_list_body", :partial => "shared/network_site_list", :locals => {:site_list => @site_list})</p> <p>And the controller code is as follows:</p> <pre><code>def change_network @user = User.find(session[:user_id]) new_network_id=params["user"]["current_network_id"] @user.current_network_id=new_network_id.to_i @site_list=Site.find_all_by_network_id(@user.current_network_id) respond_to do |format| format.js end end </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
