End User Customization of Python Product DTML
by Kapil Thangavelu 27 Aug '00

27 Aug '00

I've been fumbling with this for the last week or so. I've got a Python Product NewsSyndicate, which setups feeds for a bunch of RSS channels. I'd like to have the display for that content be end user customized in the management interface not through editing dtml on the file system and I'd like to keep this product in python (as opposed to a zclass split). i experimented with a folder that i instantiated with various dtml_views upon product creation. i then set the view methods of all the generated rss channels equal to the views in this folder. it works, but it seems a bit flaky. in retrospect this seems like a bad way to do it, since i'm basically setting up hundreds of references to a method, and if it gets deleted in the management screen i can't reassociate easily a new one to the exisiting channels. if anyone has any ideas i'd love to hear them.

keeping state of tree over different documents
by Marcus Schopen 27 Aug '00

27 Aug '00

Hello, I'm trying to do the following: - documents containing a tree navigation are created dynamically using standard_header and footer. - the navigation tree is NOT located in a frame but in a table cell which is reloaded together with the rest of the page each time a link in that navigation is selected - the navigation tree is automatically created by using a dtml-method. The problem that occurs is, that the tree`s open/close state is not correctly maintained over the different documents. A solution to that might be to append the state of the tree after selection of a link to the it's URL as ?tree-s=.... ; that means pass the future state of the tree to the selected page by using URL-Parameters. Any ideas how to do that or any other ideas? Thank you Marcus

Good morning, people. I was wondering, can Zope interface to barcodes, magnetic cards (e.g. credit cards) and other common shop-"accessories"? Feedback is greatly appretiated :)

is <dtml-unless someIndirectVariable> possible ?
by Didier Georgieff 27 Aug '00

27 Aug '00

I have a lot of REQUEST like this one to check, depending on what documents are in the folder. <dtml-unless SOMEREQ> <dtml-call "REQUEST.set('SOMEREQ','defaultvalue')"> </dtml-unless> so i gave all documents concerned 2 properties myPropName,myPropValue (in our example myPropName : SOMEREQ myPropValue : defaultvalue) So i'm able to iterate the documents and check the properties and set the REQUEST. <dtml-in "objectValues(['DTML Document'])"> <dtml-if "_.hasattr(this(), 'myPropName') == 1"> <dtml-call "REQUEST.set(myPropName,myPropValue)"> </dtml-if> </dtml-in> this works OK. But, I can't find a way to generate the <dtml-unless SOMEREQ> tag. Passing the value of myPropName seems to fail (erreur while parsing the syntax, or check the 'myPropName' instead of his value). I tried a lot of things and syntax around <dtml-unless myPropName>, but it failed. Is it a dtml-unless limit, or just a bad syntax i'm writing ? Thnaks in advance.

From date to timestamp
by Peter Be 27 Aug '00

27 Aug '00

I managed to go from timestamp to date with <dtml-var "ZopeTime(967322055)" fmt="%H:%M"> But how do convert a date to timestamp? I.e. from say: "27/08/00 23:59" to 967322xxx? All I know to begin with is the day, month and year. Would be nice if I can do this in DTML straight away. Is it time.mktime something?

How to get PARENTS[-1] from within a Python Product
by Ira Hochman 26 Aug '00

26 Aug '00

Hello- How does one retrieve the equivalent of PARENTS[-1] from within a Python Product in Zope? I have tried self.aq_parent.absolute_url() which gets the equivalent of PARENTS[0], but I need to get PARENTS[-1]. I am trying to isolate/preserve the portion of the path that contains cgi/pcgi info, if any (as in "http://yoursite.com/bin-cgi/Zope.pcgi"). Alternate approaches to accomplish the same would also be welcome. -- Ira Hochman go2ira(a)onebox.com - email (617) 598-1014 x5511 - voicemail/fax __________________________________________________ FREE voicemail, email, and fax...all in one place.
