    <p><strong>I want to have a web page where you click a button, by using AJAX I get a string from a python script, then display that string in a paragraph HTML element.</strong></p> <p><strong>I know I can do this by using Python, WSGI &amp; AJAX (theoretically I can do it this way) but its waaaay too difficult. I am experienced with CGI &amp; python.</strong></p> <p><strong>So can I do the above using CGI?</strong></p> <p>If I can how do the python script work, exactly the same as when serving a page using CGI?</p> <p>This doesn't work:</p> <pre><code>import cgitb; cgitb.enable() import cgi import os print "Content-Type: text/html\n" input_data = cgi.FieldStorage() print "hello" </code></pre> <p>When I click my button in my page, nothing happens &amp; my CGI server (which works fine for cgi page requests) gives me a http 501 error.</p> <p>My html &amp; javascript:</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"&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt; &lt;script type="text/javascript"&gt; &lt;!-- function onTest( dest, params ) { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 &amp;&amp; xmlhttp.status==200) { document.getElementById( "bb" ).innerHTML = xmlhttp.responseText; } } xmlhttp.open("POST",dest,true); xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded"); xmlhttp.send( params ); } --&gt; &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;p id="bb"&gt; abcdef &lt;/p&gt; &lt;a href="javascript:onTest('aaa.py', '')"&gt;Click it&lt;/a&gt; &lt;/body&gt; &lt;/html&gt; </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.
