Re: [Zope] displaying based on date

(It's a job posting ZClass, and I only want to display jobs that haven't yet closed.) I see in the ZQR that there is an 'isFuture' test that looks like it is associated with fmt. ZQR says for isFuture, "Return true if this object represents a date/time later than the time of the call." Can I combine this with a dtml-if? Is there a more elegant way? Yes, like in: dtml-in some_items sort=date dtml-if "date.isFuture()" [...] /dtml-if /dtml-in Where some_items is a list of objects with a date property. I think it's nice enough. You may even collapse everything in a row (untested): dtml-in "filter(lambda x:x.date.isFuture(), some_items)" sort=date /dtml-in -- "This company has performed an illegal operation and will be shut down.

Re: [Zope] how to invalidate an object in the cache?

Sounds like you need to manipulate the expiry time for the objects. I'd
suggest that that can either be done in the RESPONSE or via meta tags in the
standard_html_header to mark the page and the image as non-cacheable.
I'm actually interested in a Guru's response on this as I will need to set
the expiry explicitly to save load on the server for content that is
dynamically generated but doesn't change often.
It would work, but I'd have to set up meta tags for LocalFS objects..
I've found a better kludge: when I call the index page, I pass a "refresh" variable
along
the URL which contains the number of the modified image.
Within the index method, I then call:
dtml-call "REQUEST.set('id2',id+'_0.jpg')"
dtml-let img="store[id][id2]"
A HREF="imageForm?fnum=dtml.url_quote-id;"IMG
SRC="dtml-var
"img.absolute_url()+['','?%s'%_.random.random()][REQUEST.get('refresh')==id]""
^^
WIDTH="dtml-var "img.width""
HEIGHT="dtml-var "img.height""
ALT="dtml-id;"/A
/dtml-let
This way, the refreshed image is called with a trailing "?0.283759872" that tricks
Netscape
to think it's a new object, and reloads.
This could work for you too, maybe.

[Zope] sort=id, _.map, _.lambda woes
Hi all! I need the following: dtml-in "store.fileValues()" sort=id where "id" is a filename representing a number. Of course, sort uses it like a string and sorts it wrong. Maybe, since sortexpr= is not implemented (yet?) I could get away with: dtml-in "_.map(_.int,store.fileValues())" sort=id but _.map doesn't exist (nor _.lambda. Why?) What is the Right Thing to do? I already know the easy answer (external method) :-) Of couse I cannot add an order property to the file objects, as they're in LocalFS.

[Zope] how to invalidate an object in the cache?
I am working with photo rotating/resizing, via PIL on external method. All the images are kept on LocalFS. There is a thumbnail bonanza page, when I select a thumbnail a form is shown, and I can adjust rotation/contrast/brightness. Upon submit, the new image+thumbnail is calculated and written to the filesystem. Then the method calls RESPONSE.redirect to show the index page again. When I go back to the index thumbnail page, the image I've just rotated is displayed with the right size (which means that Zope gets it right), but not rotated (which means that Netscape reads the old image from the cache). I mean, if it was 320x200 and is now 200x320, the browser displays the old 320x200 image stretched to 200x320. I'm not digging into contrast and brightness, but the same happens. Is there a way to force the browser to discard the cache for that image? If I go "right-button, view image, shift+reload" the new image is displayed. Any idea? I'm not very knowledgeable on this matter, I don't design pages for a living. Might javascript help? Thank you. -- "This company has performed an illegal operation and will be shut down.
