Improvement suggestion: filtering by subjects

Posted by on Friday June 22, 06:18PM, 2001
from the dept.

This small patch in SquishSite.py enables to filter lists of news by subject (means display news of a particular subject).

This small patch in SquishSite.py enables to filter lists of news by subject.
i.e. this DTML shows the news headlines from squishdot folder "news" which subject is "fun".

Of course, this does not alter usual Squishdot features, as far as I tested.

Edit the SquishSite.py file and change the "item_list" method with what follows:

  def item_list(self, subject = None):
    # """ returns latest articles """
    # Modif by Gilles Lenfant (subject filtering)
    currtime = int(time())
    l = map(lambda x, p=self: x.__of__(p), self.data.map(self.id_list(currtime)))
    if subject:
       return filter(lambda x, s=subject: x.subject==s, l)
    else:
      return l

Of course, the SquishDot team is strongly encouraged to include this in the next release.

Warning: this patch has been done on a Squishdot 1.0.0 ! Check if relevant for your version.

TIA for feedback.

--Gilles

I wouldn't do it this way.

Since Squishdot is now a ZCatalog, it's much simpler and more flexible to use catalog queries to do this kind of thing.

For example, the above can be achieved, with no patching, as follows:

cheers,

I am slightly confused about this. I want to filter message posts. Where does the news object come from in Squishdot?
