Hi,

I just needed the same thing... here another way.

Deleting Zope Objects in DTML based on timestamp.

I created this for housekeeping of a file repository,very similar the the File Library app in the Zope Examples.  This dtml-method deletes items of type "File" that haven't been modified in 45 days.

Notice the syntax in the line:      <dtml-call expr="manage_delObjects([_['id'],])">

I Google'd it, apparently its handing manage_delObjects a list of one item, and that item is the item "id" from the current namespace.  The trailing comma is for a list of one item.

To test it, I commented the manage_delObjects line, and included the commented lines below, to test for the correct results.


<dtml-with Files>
<dtml-in expr="objectItems('File')" sort="bobobase_modification_time" reverse>
<dtml-with sequence-item>
   <dtml-if expr="bobobase_modification_time()<=ZopeTime()-45">
     <!-- DEL: <dtml-var absolute_url><br> -->
     <dtml-call expr="manage_delObjects([_['id'],])">
   <dtml-else>
     <!-- KEEP: <dtml-var absolute_url><br> -->
   </dtml-if>
  </dtml-with>
</dtml-in>
</dtml-with>
<dtml-call "RESPONSE.redirect('filelist_html')">

Good Luck,

-Jonathan Cyr

Look for the object DateTime in the help files of your Zope installation.
They have a nice set of methods to compare time dates.

Anyways, they all return false or true, so in your case I would convert the
time dates to integers, then perform a simple subtraction operation, and
check if the most recent date is greater to ...
seconds_in_a_day * 5.

Subject: [Zope] DTML Method - delete files


I am almost done writing the script but I need to figure out how to
compare two dates. For instance, I have this: <dtml-var ZopeTime
fmt="%m/%d/%Y">
                                  <dtml-var modification_date
fmt="%m/%d/%Y">

*** Now I need to compare the two dates to see if the ZopeTime is
greater by 5 days.

Any ideas on how to do that using dtml?
