Zope and long running sessions question...
by Christopher A. Wright 25 Oct '99

25 Oct '99

Hi, I have an application that requires the user to fill in some forms. The next form to serve up to the user depends on the contents of the last form. The transaction looks like this: user requests service: Zope starts up service Zope sends first page to the user User responds Zope decides what page to serve next Serves the page User responds ........repeat as needed Zope returns the result of the service request to the user. { for Zope read Bobo, I guess. I'm really interested in the long running Python process stuff, more than the delegation, roles etc at the moment. } I'm wondering how Zope would handle this. At the initial service request, Zope would return some html, but in some sense, it's really a function call OUT to the user to get some more data. the user then responds, but again, that's really a call to Zope. I would love to understand how Zope might work here... cheers and thanks for any help chris wright Dr. Christopher A.

ZOracleDA isn't imported in Zope
by Alexei Ustyuzhaninov 25 Oct '99

25 Oct '99

Hi zopsters! I have installed Oracle adapter in my system and when I try to click on ZOracleDA product in Control Panel I will get the following output: Product at /Control_Panel / Products / ZOracleDA ZOracleDA Import Traceback Traceback (innermost last): File "E:\PROGRA~1\kayak\lib\python\OFS\Application.py", line 393, in import_products product=__import__(pname, global_dict, global_dict, silly) File "E:\PROGRA~1\kayak\lib\python\Products\ZOracleDA\__init__.py", line 103, in ? import DA File "E:\PROGRA~1\kayak\lib\python\Products\ZOracleDA\DA.py", line 103, in ? from db import DB File "E:\PROGRA~1\kayak\lib\python\Products\ZOracleDA\db.py", line 101, in ? import DCOracle, DateTime File "E:\Program Files\Python\Lib\DCOracle\__init__.py", line 66, in ? from ocidb import Connect, error File "E:\Program Files\Python\Lib\DCOracle\ocidb.py", line 50, in ? import oci_, ociCurs, ociProc ImportError: DLL load failed: Access is denied. The funniest thing about this is that I can import either ZOracleDA or DCOracle in python window as well as connect to Oracle server with DCOracle tools. Can anybody help me with this please? The configuration is as follows: WinNT 4.0, Zope 2.0.1, ZOracleDA 2.1.0, DCOracle 1.3.0. Thanks,

This is now the managment interface works. Remember, Zope being open source, it is usualy a good idea to see how Zope does something that is similar to your problem. Since you can inspect all of Zope's behavior from the source, you can find all kinds of tips and tricks. Zope is not only an application platform, but it is also an application written *with* that platform, just like web applications you and others want to write. -Michel

hello all, How on earth does one call manage_users? The quick reference says: manage_users([submit, REQUEST, RESPONSE]) User Folder, Manage Users. submit can equal 'Add...', 'Add', 'Edit', 'Change', or 'Delete'. Add and Edit use the following variables from the REQUEST object: name,password,confirm,[roles,domains]. ??? but,  returns an error. What is the correct syntax???? DR

Since you're calling the method on the instance object specifically, Zope knows which object you're trying to use. So, assuming your propertysheet is called InstanceConstants, then all you need to do is: <dtml-call "propertysheets.InstanceConstants.manage_changeProperties(REQUEST)"> <dtml-call reindex_object> The REQUEST['id'] thing is just used when you're adding the object in the first place, because at that time you need to define the id for the new object. Since methods are invoked on specific objects, you don't need to specify the id. Kevin

Q: How to pass session information from outside into Zope?
by Avus 25 Oct '99

25 Oct '99

Hi, how do I transfer session (or authentication) information from a non-Zope site (PHP or else) to a Zope site? Cookies just work on the same site, hidden fields just work for 'post's. So I'll probably have to pass the information in the URL. My Q: How do I get Zope to strip and evaluate the id information I pass in the URL string, even if the Zope object I'm calling is not explicitly prepared to do that (i.e. it is no DTML method that has code for this)? Zope URLs are often created on the fly (db query), so the handling of the id string in the URL has to be acquired by some inheritance magic, I guess. Any ideas how to solve this? The inted is that the user doesn't have to login twice (the session id could be stored in a common db).

If you want to get the right URL, you'll have to prepend <dtml-var SCRIPT_NAME> to the path call. getpath will definatly not include the machine name in what it returns, there is no way it can know this. Your browser is probably infering an incorrect URL of a relative path. -Michel

Catalog.getpath(data_record_id_) without Zope ????
by Geir B Hansen 25 Oct '99

25 Oct '99

When listing catalog-search-results <dtml-var "Catalog.getpath(data_record_id_)"> gives me the correct URL, but omits the "Zope" in the start of it... instead of returning : mydomain.com/Zope/myfolder/mydocument_html it gives me : mydomain.com/myfolder/mydocument_html - which really doesn't point to anything ... Anybody experienced anything similar , or preferably know how to fix it ?? Thanks... ------------------------------------------------ Geir B Hansen geirh(a)funcom.com Web-designer / Graphic artist Funcom Oslo ------------------------------------------------
