Re: [Tutor] Really basic web templating
Check to see if mod_python is installed/installable.

Re: [Tutor] Really basic web templating
There was another host that I wanted to mention along these lines (for Python sites) that I think is even better: VPSLink (http://www.vpslink.com). They allow root SSH access, and can install your choice of OS (lots of linux flavors, ubuntu, SUSE, CentOS, etc) from a control panel. Aside from that they are similar to WebFaction, but having that much flexibility, with the base plan only ~$8/month, is pretty awesome. -Sam - Original Message From: Kent Johnson <[EMAIL PROTECTED]> To: wormwood_3 <[EMAIL PROTECTED]> Cc: Python Tutorlist Sent: Monday, October 1, 2007 8:36:03 AM Subject: Re: [Tutor] Really basic web templating wormwood_3 wrote: > My host actually does support Python.

I am going to assume from your description that you are looking for a
way to use a *single* cgi script to handle all page requests to your
site, and respond with the appropriate template based on the requested
url. If I have assumed incorrectly then you can safely ignore the rest
of this message. :)
Some mod_rewrite directives are available to .htaccess, IIRC -- so that
may be a valid option, only if your webhost has enabled mod_rewrite of
course, and they allow overrides with htaccess.
Otherwise, this is a fairly simple task if you are content with "ugly"
urls. For example, given a url something like
http://mysite.com/mycgi.py?page=index.html, a very basic cgi
implementation might look like this:
#!/usr/bin/env python
import cgi
form = cgi.FieldStorage()
print "Content-type: text/html\n"
try:
page = form["page"]
except KeyError:
print file('custom404error.html').read()
else:
content = file(page.value).read()
# ... do something with content ...
print content
---
If your webhost has enabled mod_actions (I suppose this is unlikely),
you can also do the following in .htaccess (again, only if they allow
override):
AddHandler my-python-handler .html
Action my-python-handler /cgi-bin/handler.py
which should force apache to set an environment variable named
'PATH_TRANSLATED' with the value of the requested url, and call
'handler.py' for any requested file with an .html extension (that
exists) in that directory -- honestly, I've never attempted this myself
-- and there is probably a better way, but it's all I can think of ATM.
If the file doesn't exist apache returns a 404, which is only desirable
if you plan to store your templates on the filesystem. And you can use
the os module to access the cgi environment variables:
#!/usr/bin/env python
import os
print "Content-type: text/plain\n"
try:
path = os.environ["PATH_TRANSLATED"]
except:
path = 'PATH_TRANSLATED is not defined.'
print "The requested url is:", path
---
Perhaps you could convince your webhost to install mod_python, if they
haven't already. It's fairly trivial to write a simple mod_python
handler to accomplish exactly what you are trying to do.
HTH,
Marty

"wormwood_3" <[EMAIL PROTECTED]> wrote > ...nearly every tutorial I have seen regarding Python and CGI only > have to do with form submissions, Thats the most common use of CGI but really a form submission is just a standard HTTP GET/POST request with some predefined variables. In reality the user requests your python script and whatever the script sends to stdout goes to the browser So all you have to do is read in your header, body and footer and stitch them together then send them to stdout. If you want richer functionality you can use templating engines from the frameworks without the framework being present. For example the kid system used in TurboGears can be used standalone to give sophistoicated templating without anything special being done to the web server. Indeed it can even be used outside a web server context. But from your description simple CGI and Python may be all you need.

If you request a URL you get a script which serves the page if it exists, or creates a blank one if it doesn't. You can use Python's string template module as an easy way to format up variable text into style templates you set up as text files, or use a database backend, or whatever. --steve > -Sam > > > - Original Message > From: Ian Witham <[EMAIL PROTECTED]> > To: wormwood_3 <[EMAIL PROTECTED]> > Cc: Python Tutorlist > Sent: Sunday, September 30, 2007 11:52:38 PM > Subject: Re: [Tutor] Really basic web templating > > > > On 10/1/07, *wormwood_3* <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > Hello all, > > I am trying to think of a way to make this happen, but it may not be > at all possible:-) I would like to use Python to generate pages on > demand for my website.

[Tutor] Really basic web templating
Hello all, I am trying to think of a way to make this happen, but it may not be at all possible:-) I would like to use Python to generate pages on demand for my website. By this I mean, when someone hits www.mysite.com/pagex.html, I want to generate the page pagex.html via a Python script. I have a script setup that can generate a page from a template file and a file with the body and title of the page in particular I want to generate. Now from this, I need to somehow be able to respond to requests, and then generate the page based on the page requested. I want to do this because my site is on a shared hosting account, so I cannot install a web framework like Django, and the site's pages will be rather simple. At the same time, I would like to use templating, so I do not have repeated identical code between the pages. Any ideas on this?
