    <p>What I want to do is have a single python program in cgi-bin that is executed by each of many pages on the site, and displays a line of HTML on each page that is different for each file, but keyed to the URL of that file on the site.</p> <p>I know how to get the URL using javascript (e.g. on <a href="http://constitution.org/cs_event.htm" rel="nofollow">http://constitution.org/cs_event.htm</a> ):</p> <pre><code>&lt;script language="javascript"&gt; var myurl = document.location.href; document.write(myurl); &lt;/script&gt; &lt;br&gt; &lt;script language="javascript"&gt; var myurl = document.location.href; document.write("&lt;A href=\"" + myurl + "\"&gt;" + myurl + "&lt;\/A&gt;"); &lt;/script&gt; </code></pre> <p>And I know how to create a link that opens a page to execute the .py script when one clicks on it:</p> <pre><code>&lt;a href="http://constitution.org/cgi-bin/copy01.py?myurl=myurl"&gt;Here&lt;/a&gt; </code></pre> <p>Here is the python script so far:</p> <pre><code>#!/usr/bin/env python # This outputs a copyright notice to a web page import cgi print "Content-Type: text/html\n" form = cgi.FieldStorage() thisurl = form.getvalue("myurl") print """ &lt;html&gt;&lt;head&gt;&lt;/head&gt; &lt;body&gt; """ print """ Copyright &amp;copy; 1995-2011 Constitution Society. Permission granted to copy with attribution for non-profit purposes. """ print """ &lt;/body&gt;&lt;/html&gt; """ print thisurl </code></pre> <p>But it is not so obvious how to pass the variable value to the .py script, and have it automatically display the URL of that page the way the javascript does, or display a line of HTML that it will get from a dictionary in which the URLs are the keys and the HTML lines are the data.</p> <p>Ultimately, I want to be able to generate, using a single .py script, all the footer content of each page, that can be maintained from a single file that I can edit to make changes that propagate everywhere.</p>

    2. COWe still haven't solved the problem posed. I want something, such as a jquery script, that executes a python script that does nothing more than display a line of HTML chosen based on the url of the calling HTML page, a different line for each URL. Initially, it can show just the URL, but the eventual solution is to use the URL as a dictionary key to select the line as a value of that dictionary.

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.
