Zope Folder Reference
by Niclas Kuehne 16 May '02

16 May '02

Hi! I would like to access the properties of a folder that I can only refer to by a variable. In my case it is a folder named the same as the creator's user name of the a page. For example: <dtml-with userdb> <dtml-with creator> <----- This should be a variable to the creator <dtml-if FirstName> <dtml-var FirstName> </dtml-if> <dtml-if LastName> <dtml-var LastName> </dtml-if> </dtml-with> </dtml-with> I have a userdb folder witch contains subfolders for each user name. These subfolders have the properties "FirstName" and "LastName". How do I access these subfolders by using the "creator" variable on each page. Any suggestions on how to do this? Or is there any simple Zope internal database for user management or some product that does this better? Nic nk(a)nkmail.com

How to get the "pure" source of a pagetemplate back ?
by Joachim Schmitz 16 May '02

16 May '02

Hi, I am editing all my sources on the local file system, and upload them to the Zopeserver, with a heavely extended version of load_site.py. Some care had to be taken if more than one person modifies the online site. But if there were changes, I could just cut and paste the source from the textbox into my local editorwindow. Until pagetemplates came around, here I only get the text with all macros expanded. So my question: how do I get the pure unexpanded text of a pagetemplate from a Zope-server back ?

recompile all Python Scripts in Zope 2.5.1
by Milos Prudek 16 May '02

16 May '02

After import of a 2.4.3 site, Zope 2.5.1 logs a message recommending a recompile: 2002-05-16T11:39:58 INFO(0) Script (Python) Some of your Scripts have stale code cached. Since Zope cannot use this code, startup will be slightly slower until these Scripts are edited. You can automatically recompile all Scripts that have this problem by visiting /manage_addProduct/PythonScripts/recompile of your server in a browser. But the URL /manage_addProduct/PythonScripts/recompile does not work. What is the correct URL? -- Milos Prudek

Anyone know why http://codestackers.com is not accepting http requests? Are they all on holiday down there or is it something worse?

View Permissions
by Richard McKinley 16 May '02

16 May '02

Hi, I want to limit access by role to the functionnality within my website. Firstly, I need to remove the view permission from the anonymous role so that users are required to log on to view certain pages. I attempted to do this by unchecking the view permission against the anon role in the security tab of the users folder within the folder I was working in. However, this appears to make no difference - I have even added a dtml-if statement to the contents of the page I'm testing to explicitly check if the current user has view permissions before displaying any data: <dtml-if expr="_.SecurityCheckPermission('View', this())"> .. page content .. </dtml-if> Unfortunately, this appears to make no difference: I've checked that the current user is anonymous: (which proved the theory) <dtml-var expr="_.SecurityGetUser().getUserName()"> Any help much appreciated! Thanks, Richard _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

Being a newbie is very hard: fortunately help from the community counterbalances the frustration of sifting thru howtos, mailing list and books. Yes, I agree with your comments about the namespace, I think that's what's causing the problem. In fact I do have a <dtml-with Machine> in a method that does not seem to be closed properly, but when I try to add a closing tag it baulks. Fortunately Casey Duncan from zope.com has answered my mails and asked me for the code of my methods so I think I should soon get a reply. Thanks for the compliment on the structure. We're now studying going on to page templates, so the structure may change slightly. We also have to work out how our editors submit their pages which is a real headache, since we have editors that in our past system used to create whole mini-sites and ftp them to our server. We now want them to use our template, but they cannot ftp from dreamweaver with objects called index_html since there is no extension, and if they add an extension so that Zope recognises them as ZPT we no longer have the default index_html object.

Re: [Zope] manage_changeProperties Question

Forget it. Used a different tactic. The following python script works... for obj in context.objectValues('DTML Document'): obj.manage_changeProperties(on_host_committee=0) I'm not sure why the DTML doesn't, however. Hmmmm.... Sorry to bother you all. This is the upteenth time that I've posted a message, only to figure out the problem about 30 seconds later.

Disapearing cookies or problems with cookies and chache
by Robert Rottermann 16 May '02

16 May '02

Hi, I have an object with two properties. A German one, and a French one. Depending on the settings of a cookie I want the appropriate property content displayed. My problem is, that this seems not to work when the page is served from the local cache. Does anybody have an Idea how to force the display of the correct data. Or do you have a hint why cookies could "disappear" thanks Robert www.redcor.ch

XML in Zope
by Dan Shafer 16 May '02

16 May '02

I had in mind to use DTML documents as the storage mechanism for the main documents at the core of an application I'm building for a client, but it turns out they are going to need to do some things that would be pretty cumbersome in a DTML document or method. So I'm investigating using XML for these documents. Searching zope.org turns up a lot of stuff about XML but, as far as I can tell, only one product: XMLDocument. But it describes itself as out of date and replaced by ParsedXML, which, as far as I can tell, hasn't had a product release yet. I can't tell from the ZQR which XML implementation it is documenting. This is all made more complex by the fact that I cannot for the life of me get an external script using any of the xml library stuff to run, but I'm not asking for help with that at the moment. I'm trying to work my way through it. So should I download and install the XMLDocument product and use it from DTML (ugh) or is there a better way to do this?
