ZopeTree tree-expansion cookies: question
by Jean Jordaan 26 Mar '03

26 Mar '03

Hi Philipp I've just start using your ZopeTree product (with a lot of gratification, I might add), and I've got a question about how the 'tree-expansion' cookie works. The behaviour that prompted my question is this: using Mozilla 1.2.1, when browsing around a site which displays a tree, the state of the tree depends on where I am in the site. For example, at /position/a I might have collapsed half the tree. I go to /position/a/b and expand everything. If I then go to /position/a again, the tree is half-collapsed, the way I left it, instead of the way I set it while at /position/a/b. I checked the cookies Mozilla was holding, and saw that it had a 'tree-expansion' cookie for every path where I changed the state (i.e. every path where setCookie was called). I suspect this is because the cookie is set without a 'path' specification, and Mozilla is being conservative and restricting the cookie to the path where it is being set. request.RESPONSE.setCookie(request_variable, tree_expansion) To fix this situation for me, I can change ZopeTree to set the cookie's path to the path of the tree's root_object. What do you think of that? -- Jean Jordaan http://www.upfrontsystems.co.za

Hello, I m developing a product that will do the following: My form has the following: ID, TITLE, FILE fields to fill out. After I have filled out the field, I click submit, I want to create a folder with the file I uploaded within the folder. My folder name will be the id, and the file id will be the file name. Currently, I am able to use my product to create a folder and a file, but I don't know now how to put the file within the folder. Help and tips would be greatly appreciated. Thanks

Cannot connect to zope from zope server
by Michael Long 26 Mar '03

26 Mar '03

Hi all, I have lost the ability to connect to zope from the server. I was logged in when I attempted to add a new folder I could not enter data in the input box. Upon clicking refresh I was told that I cannot connect to the server. I can connect from other machines so zope is alive. I went as far as rebooting the machine and get the same results. Where do I start to look to resolve this? Specs: SuSE 8.1 Zope 2.6.0 (built from source) Python 2.1.3 Thanks, Mike

You may ask him about details. My friend also did ( well almost) integration between Notes and Zope. He created a servet that takes the Notes authentication information and stores into Postgres and forwards request to Zope. In Zope modified exUserFolder then handles everything from that point on. He did not write to Zope part to finished state, but rather did just a proof of concept that it is doable and would not require miracles. -huima

Zope and Objects
by Jeff Childers 26 Mar '03

26 Mar '03

I'm starting to get the "big picture" but I'm still a little fuzzy on the details, particularly about objects and the ZODB. I'm hoping that someone can give me some brief pointers to where the answers the these questions lie. I have read a *bunch* of Zope doc and I'm pretty handy with Python. 1) Where are data object classes defined in Zope? I get the persistent object thing. Very cool. So let's say I want to write a billing system. I have customer objects, invoice objects, and payment objects. [ Customer [ Invoices [Payments] ] ]. a) Where do I put the code that defines each custom class? Scripts seem to be for def-functions. Do I have to put this outside Zope? b) Do I use ZCatalogs to 'index' my objects so I can query them similar to SQL? If so, how/where do I add my custom classes to the ZCatalog? 2) How do I instantiate and persist (through the session) a particular instance of the class from the ZODB (i.e. a certain customer)? I realize these are big questions. Any pointer toward answers, even which documentation I should be reading, would be helpful and greatly appreciated. Thanks! Jeff Childers

DateTime Error-Recurring
by Zope＠Stylus 26 Mar '03

26 Mar '03

Hi all There is one issue I would like to clarify.The date time module is throwing an erro everytime I open the ZMI. I have a zsql mehtod ...> select DateTime(ldate) from tbluser Now as long as the ZMI is not opened there is no issue with the performance.But at any point of time if I open the ZMI for doing some editing then I get the following error. Zope Error Zope has encountered an error while publishing this resource. Error Type: Invalid Date-Time String Error Value: 2002-10-24 12:01:35+05 -------------------------------------------------------------------------- Troubleshooting Suggestions a..

Is this problem being faced only by me or others as well.The way I am resolvin this issue is very non logical.Could you please guide me here and point out where I may have gone wrong.Thanks for all help in advance Thanks and Best Regards John Kunchandy --- Outgoing mail is certified Virus Free.
