Making documentation easier
by Chuck Burdick (TT) 14 Jan '00

14 Jan '00

I'm working on some documentation for ZFormulator, and I'm running into various issues trying to cleanly present DTML examples. The problem is that it seems that Zope ALWAYS interprets dtml tags unless you use HTML entities (like < and > instead of <, >) to surround your tags. This happens in <pre>...</pre> HTML tags or as example code in structured-text. However, using HTML like this defeats much of the convenience of documenting in structured-text. Is there a way to stop Zope from interpreting the tags? Alternatively, how difficult would it be to create a <dtml-suppress>...</dtml-suppress> tag to suppress tag interpretation? Imagine the following as structured-text: ====BEGIN==== Example1 - Won't work because Zope interprets tags:: <dtml-in myexample> <dtml-var title> </dtml-in> Example2 - Hacked to make code appear as code: <pre> <dtml-in myexample> <dtml-var title> </dtml-in> </pre> ====END==== Notice that example1 tries to use the example code symbology of structured-text and that example2 "cheats" by embedding HTML into the structured-text.

Very important for CatalogWare zopists
by Jason Spisak 14 Jan '00

14 Jan '00

Zopists, I have submitted this to the Collector and it is major for people who have items in their ZODB that are Catalog aware. To create the bug follow these steps: 1.Create a Catalog Aware ZClass 2.Create an instance of that class 3.Make sure it is indexed by looking in the Catalog "Catolaged items" tab 4.Notice that there is *no* slash in front of the indexed url: "MyFolder/myobject" 5.Now clear the Catalog 6.Go to the "Find Items to Catalog" 7.Select just your New ZClass meta type so it is quick 8.Click "Find" 9.Make sure it is indexed by looking in the Catalog "Catolaged items" tab 10. Oh no! It has a different url. A leading slash! "/MyFolder/myobject" 11. Click on the link. It's broken! What this means is that if you have a lot of items in you Catalog don't ever ever ever use the "Find" machinery until Digital fixes this(It worked in 2.0.0 Final). You will end up not being able to edit/reindex your objects, and the links in your applications may not function. I am looking for how "Find" and index_object in createInObjectManager are different. No luck yet. All my best, -- Jason Spisak webmaster(a)hiretechs.com

Re: Zope-Dev digest, Vol 1 #351 - 1 msg

Brian, I use the default constructor given to me by creation of a ZClass. To make it realistic, I have a propertysheet that has a few properties in it. When you createInObjectManager, the Catalog gets called, soyou have to call reindex_object again to get the propertysheet to be in the Catalog. And then I redirect. There's not absolute_url call, and it's getting indexed from where it is in the ZODB tree. (no acquisition) Have you followed those steps with a fresh Zope? It doesn't give you two different Catloged urls? Jason Spisak

RE: [Zope-dev] Factory pollution, scopes, zope hosting
by Toby Dickenson 14 Jan '00

> I already described a problem of ``factory pollution'' I'm > facing ...... I was going to settle for deleting the > Factories and making some scripts to add all instances > programatically This change will have some other undesirable (and possibly unexpected) consequences. If the user can not create the object using ObjectManager, then he can not paste them or import them either. This actually leads to further 'factory pollution'. Many of my objects are copy/pasteable but not manually createable. I have to create a dummy factory (with a bogus entry on the list) to pacify ObjectManager.

Creating and adding Nodes in the XMLDocuments
by Stephan Richter 14 Jan '00

14 Jan '00

Hello Everyone, Does someone knows XMLDocuments and DOM pretty well. Well then I have a nut for you to crack: Short Form: I am implementing a little message board using XML documents. How can I create Nodes, so I can add them to the document or are there other ways to do it? The Long Form: For projects I do as living I alway keep all documentation in HTML and XML. I also have a task list, with dates and status in XML form. Now I thought it would be a good idea, if co-workers and clients could comment on some of the task descriptions or write some updates about the tasks. I thought that it would be great if this could be in the form of a small Message Board saving all the comments in the same XML file for completeness. My XML will look something like this: (There is actually more XML, but it is irrelevant to this case.) ... <task ... > <start>...</start> <end>...</end> <abstract>...</abstract> <messages> <message name="Subject"> <date>...</date> <author>...</author> <body>...</body> <replies> <message>....</message> </replies> </message> ... </messages> </task> With the help of Zope, how can I add a single message into either the 'messages' or the 'replies' not using the Zope management interface and only a programmable way. Well I thought using acquisition I prepare the addMessage method in the root folder of the XML document. Therefore I can reach it from every XML node. I also do not have to worry then about passing the URL. Now I have already the parent node for my message, making use of absolute_url() and objectValues(). And I know there is a XML function let me add another node. MY PROBLEM: I do not know how to create a node or to add one simply to the document. Is that really that hard? Thank you guys for your great help and work.

broken ZSQLMethods in CVS
by Sascha Matzke 13 Jan '00

13 Jan '00

Hello, it seems that the line context.registerHelp() added to the file __init__.py by amos with version 1.15 breaks the SQLConnectionIDs method... I could not explain why. It simple doesn't work when it is there.

HTML() security questions
by Martijn Faassen 13 Jan '00

13 Jan '00

Hi there, I'm working with Chuck Burdick on some changes to ZFormulator that allow arbitrary DTML in some field definitions. Chuck got it working by doing this: HTML(foo).__call__(self) where 'foo' is a string that may contain DTML statements. This appears to work, but does not do any security checks; if the DTML for instance contains this: <dtml-var locked> where 'locked' is a DTML Method that should be inaccessible by anonymous ('view' and 'access contents information' both turned off), the code happily continues and lets anonymous view 'locked' just fine. How to pass along authentication information to the HTML() object? (am I asking the right question?) Is there any documentation on how this works altogether? I dug some through the source but I'm not getting very enlightened. It appears that some validate() method is called, but I'm basically quite in the dark. This kind of issue would likely be important to many product developers that want to use DTML in this way; we don't want products to leave such security holes. Regards, Martijn
