[Zope] CMFSin time errors
Title: CMFSin time errors
Hi,
I'm getting some errors with certain feeds, but not others, in CMFSin. The errors seem to have something to do with the portaltime and localized time. Someone suggested changing the permissions for anonymous to fix this. Doing that made all my feeds malfunction, so that's not the right answer.
I know CMFSin is old and it seems to be getting flaky. But I really need an aggregator for my project, and it doesn't seem like there's anything much better out there right now.
Here's what happens when I use a feed from National Public Radio (http://www.npr.org/rss/rss.php?topicId=3). I know the feed is working. CMFSin's debug panel shows the results of the feed very plainly. The problem is in the display of the feed (which is either Zope or Plone's fault, though I can't tell which right now):

RE: [Zope] RSS feed: post-processing?
Hi,
OK, let me see if I can do that...
I've already figured out that a python script/external method solution
is what I'm after. But how to make it work?
Anyone know about Greasemonkey in Firefox? Basically, it embeds a handy
link in Web pages that have ISBN numbers in them (unique identifier for
a book). When you configure Greasemonkey right, it checks for the book
in your local catalog and returns a link to that book in your local
library catalog. The trick is to use the same idea, but inside of Plone
with an RSS feed that displays current bestsellers or other book-related
stuff where there's an ISBN included.
Here's the sort of python script I need, to the best of my knowledge,
though the first function I can't use (it checks against an Amazon
Wishlist--I don't want anything to be dependent on Amazon or a
particular browser). Jon Udell provided it, and he's the one who wrote
the LibraryLookup bookmarklet that does something similar to what I
want:
import amazon, re, urllib2
wishes = amazon.searchByWishlist('BNQ1T3SLPJS7');
def rss( items ):
return rss version=0.91
channel
titleLibraryLookup reminders/title
linkhttp://www.amazon.com/link
descriptionRemind me when books on my Amazon wishlist become
available at the library/description
%s
/channel
/rss % items
def isAvailable ( isbn ):
url = 'http://ksclib.keene.edu/search/i=%s' % isbn
page = urllib2.urlopen(url).read()
return re.search ( 'AVAILABLE', page ) is not None
items = ''
for wish in wishes:
isbn = wish.Asin
if ( ( re.match( '\d{7,9}[\d|X]', isbn ) is not None) and
isAvailable(isbn) ):
items +=
item
title%s/title
link%s/link
description%s/description
/item\n % ( wish.ProductName, wish.URL, wish.Authors.Author )
output = rss ( items )
name = 'libraryReminders.xml'
f = open(name,'w')
f.write(output)
f.close()
So, I need to simplify this script (get rid of the wishlist stuff),
create an external method for it, then figure out how to get the
template in CMFSin to call the external method. I've never done any of
this before (which probably explains why I have a hard time describing
my problem better).
The CMFSin template I need to alter looks like this, and I'm not sure
exactly where or how to call the method:

Sorry Eva,
You'll need to explain your problem more succintly for people to be able
to help. If you really do need to scrape the urls from the text, then a
combination of python's xml handling and regular expressions is probably
what you're after, best done in an external method and not a python
script...
cheers,

[Zope] RSS feed: post-processing?
Title: RSS feed: post-processing? Hello, I've been puzzling over something but can't figure out a solution. I have an RSS feed providing the content behind all the links on this page: http://demo.plinkit.org/interestsideas/goodreads/booklists. There's a nice bookmarklet tool in the world called LibraryLookup that lets you check whether a book you find on Amazon or something is in your library's catalog by scraping up the ISBN and launching an ISBN catalog search. It's a _javascript_, really. I thought I would adapt this to create a little add-on for the stuff the bestsellers RSS brings back to my site. What I need to do is pluck out the ISBNs in the links on a page like this one: http://demo.plinkit.org/interestsideas/goodreads/sinList?synmap=HardcoverFiction The ISBNs are all in the URLs for the book titles (isbn=Some10digitNumberHere). How would I look for a piece of text in that shape, i.e., isbn=5893193390, then, if it's there, copy and paste that piece of information into the LibraryLookup _javascript_ I have. The end result should be that, if there's an ISBN in a feed result, an extra link appears for each entry that says something like Check the catalog, which you can click to look that book up in your own library's catalog. I've been staring at the template that formats the RSS feed to figure out whether any TAL _expression_ would work for this. I've been playing with a short Python script, then wondering how to call it within that template, but I think I have to use regular expressions to do it. I'm sorry to be so lost on this, but I guess I am. I'd love to do something cool like this for our little Plinkit libraries. Can anyone help? I'll take anything from a broad strategy to actual code snippets (I'm a terrible programmer but a good librarian).
