Webware for Python

hi there,

i'm writing a simple blog system with python to learn the language and 
the webware framework. i've figured out most of the basic things, and
now i'm moving to more advanced stuff.

i was wondering what is the best way to include static contents in a 
webware servlet. consider this situation: tipically a blog sidebar 
contains a list of things that do not need to get updated frequently 
(blog rolls wih a "last updated" date, a calendar, recent photos--just 
to name a few).

i thought to update this things on a, say, daily basis via taskkit.
a tipical blog roll (example here: http://simon.incutio.com/)
generation task  would be:

* read a db table and fetch a service like weblogs.com with a list
of blogs of interest
* parse weblogs.com output and build an HTML <ul> list with blog title 
and "last updated" value
* write HTML snippet to disk

so, at every page request webware just include such static
HTML list  in the servlet output instead to compute a possibly
lengthly operation.

i've seen that Page has an includeURL() method, where URL is the URL
for another servlet, not a file. correct? of course i could
add something like to my WeblogPage object:

def includeFile(self, fname)
   included = file(fname, 'r')
   s = included.read()
   return s

to include an arbitrary file, but i would like to known how
you would solve this problem.

thanks in advance.

later,
deelan

PS: from the taskkit docs it's not clear to me how
to specify frequency for a task (say twice a day), once
a week and so on.

For this type of information you have many choices Easy: Use Cheetah to render your pages, Somthing like: #cache timer='30m', id='cache1' <ul> #for $blog in $blogroll <li><a href="$blog.url">$blog.title</a></li> #end for </ul> #end cache Flexable Cache it in yout module, use a module level variable to hold the data and use TaskKit to update it. I would not store this type of info to disk. Another option is to write the entire blog page to disk as an HTML page (how often does that update?) and then use Webware as a 404 handler to generate pages on the fly or update them as needed. -Aaron deelan wrote: > hi there, > > i'm writing a simple blog system with python to learn the language and > the webware framework. i've figured out most of the basic things, and > now i'm moving to more advanced stuff. > > i was wondering what is the best way to include static contents in a > webware servlet. consider this situation: tipically a blog sidebar > contains a list of things that do not need to get updated frequently > (blog rolls wih a "last updated" date, a calendar, recent photos--just > to name a few). > > i thought to update this things on a, say, daily basis via taskkit. > a tipical blog roll (example here: http://simon.incutio.com/) > generation task would be: > > * read a db table and fetch a service like weblogs.com with a list > of blogs of interest > * parse weblogs.com output and build an HTML <ul> list with blog title > and "last updated" value > * write HTML snippet to disk > > so, at every page request webware just include such static > HTML list in the servlet output instead to compute a possibly > lengthly operation. > > i've seen that Page has an includeURL() method, where URL is the URL > for another servlet, not a file. correct? of course i could > add something like to my WeblogPage object: > > def includeFile(self, fname) > included = file(fname, 'r') > s = included.read() > return s > > to include an arbitrary file, but i would like to known how > you would solve this problem. > > thanks in advance. > > later, > deelan > > PS: from the taskkit docs it's not clear to me how > to specify frequency for a task (say twice a day), once > a week and so on. > > > > > > > ------------------------------------------------------- > This SF.net email is sponsored by: VM Ware > With VMware you can run multiple operating systems on a single machine. > WITHOUT REBOOTING!

It includes the logic to generate its HTML content by finding a Cheetah template with the same name as this class plus the '_tmpl.tmpl' suffix. (This template has been previously complied into a python module 'named servletname_tmpl') It imports that template, registers itself as the template's servlet (containing the business logic the template may need), and then renders the template by calling its respond method and passing the resulting HTML string to the writeln() method.""" def writeHTML(self): #print ">> baseservlet.writeHTML()" tmpl = self.template() tmpl.servlet = self self.writeln(tmpl.respond()) def template(self): templateName = self.__class__.__name__ + '_tmpl' importLine = 'from %s import %s as template' % (templateName, templateName) exec(importLine) return template() def hasUser(self): return self.session().hasValue('user') i'm trying to guess here, but if i understand correctly basically here an external TMPL is imported dynamically in the servlet using its name to lookup the right template fiel. a "baseservlet" subclass implements per-page servlet logic and set itself as ref servlet. i'm wondering if there's a more elegamnt way to dynamically import a class, that exec(importLine) seems a bit brutal to me :) i stil have to try this, but seems a smart approach. later, deelan
