ZODBCDA 3.1.0b2 and Zope 2.2 as a Service on NT
by Jim Sanford 03 Aug '00

03 Aug '00

I am having problems with Zope 2.2 and ZODBCDA 3.1.0b2. When I start Zope manually with the start.bat my ZSQL methods work fine. When I start Zope as a service, every ZSQL method returns a SQL error that states that the table I am looking for does not exist. Anybody out there know what's going on?

Batchpeocessing with multiple selection
by vikas 03 Aug '00

03 Aug '00

Hello, I am using Zope sine last couple of months. I have been using zope from source version Zope-2.1.6-src. My operating system is Turbolinux6.0 and my database is MySql. I have to make an search on a column having multiple selection i.e take for example I have a column for city in one of my tables which also contains many other columns. Now i make a search on multiple city along with the state in which that city belongs. The search is working fine I get all the data i want, But my problem is that i wan to display only 10 rows on the page.For this i am using batch processing. But it is giving me errors Such as key error [city],[state] and gives the url of my page where i m using batchprocessing. Can someone help me out how to overcome the problem this problem as this is very urgent for me. I think the varibles are not geting passed again when i click on next sequence. Thanx in anticipation of a reply and warm regards to all. Hope I am able to explain what my probelm is ? Vikas Mahajan

Not having sufficient documentation makes it a recipe for insanity. (Save yourself, it's too late for me!) > I'm a bit fuzzy on this, though. Shouldn't there be an > easy way to generalize databases for this purpose? Why do > we need PostgreSQL, Oracle, Gadfly, ... versions? I'd > like to be able to just choose a connection ID and go. The gist of it is this: First you create (or use the default) UserSource. It's basically an empty box that is used to contain the various methods used to authenticate a user. You can have more than one UserSource, meaning you could have US's validating against SMB, LDAP, UNIX passwd, NIS, etc. (i.e., pretty much anything that Python will talk to) all running in conjunction. If validation fails against the first US, LM will simply drop through to the next and so on, until it either validates the user successfully, or drops out the bottom and denies access. You will first need to create a method for determining if a user exists. If the user exists, return 1, otherwise 0. A second method is required to take the entered username and actually look up a password, validate it against the password entered by the user and return success (1) or failure (0). A third method is used to look up the user's roles and return them as a list. These roles should match up against either default Zope roles, or preferably roles you've created for the purpose. You then lock down permissions on the desired folders/objects so that only users with the correct roles can access those objects. And lastly, a forth method is needed to return a list of valid net domains from which the user is allowed to log in. If you don't want to restrict logins by domain, then simply return an empty list. So, regarding your question about why should it matter which database, it doesn't. Not much anyways. US covers a much broader spectrum than just databases. As I indicated above, pretty much anything you could conceive of to store user data in, LM can interface to it. For some US's you may need to craft one or more external methods in Python. If it's a DBMS like Postgres, Oracle, MySQL, MSSQL, you will need a database connection method, and you will need SQL methods to fulfill the above four validation steps. Which brand of database you connect to is likely only going to affect minor issues of SQL syntax within your methods, if that. The way your user data is *structured* will have more impact than which database you use. That leaves out a ton of detail, but should hopefully answer your immediate questions and then some. Feel free to drop me a note at cwilkins(a)boinklabs.com and we can further discuss getting your LM up and running. -cw-

Confusing aq - I don't get it, anyone know why?
by Brad Clements 02 Aug '00

02 Aug '00

I've lost my Zope zen, why doesn't this work? My folders and documents / (folder) strader (folder) FormatDate (external method) outbound (folder) PackagInfo (dtml document) FormatColumnTable (dtml method) PackageInfo has code like this: <dtml-with "GetDB().Package.TrackingNumber_index.select(trackingnumber).fetchone()"> <dtml-var FormatDate> <table width="100%" border="0"> <dtml-var "FormatColumnTable(columnlist=packagecolumns,obj=GetSelf(),notable=1)"> </dtml-with> FormatColumnTable has code like this: <dtml-let value="something "> <dtml-var "FormatDate(date=value)"> </dtml-let> However this FormatDate raises a NameError in DT_Util.py, line 335 (version 2.1.6 of Zope) Is PackageInfo's use of dtml-with blocking acquisition of FormatDate? The object returned for use with dtml-with in PackageInfo raises an AttributeError when trying to find FormatDate as an attribute, this is correct... what gives?

You have hit on exactly the reason why we didn't implement DAV level 2 locking yet :^) It would have been relatively simple to do so, but it would have been in a way that only DAV clients would respect locks. In an environment where people may be changing content via HTTP, FTP, DAV, xml-rpc, in versions, etc., it seemed like it would be better to think harder about the 'locking problem' and what would make the most sense given all the things going on. Unfortunately we haven't been able to get back to thinking about that yet. I'd love to see someone take up the mantle for this on dev.zope.org though :^) Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

boolean property bug
by Aleksander Salwa 02 Aug '00

02 Aug '00

Probably I found a bug in handling boolean properties in Zope 2.2.0. I can only set them "on", and then can't turn "off". I can have default value "off" (in ZClass definition), but after first switch to "true", it can't be changed. It only refers to handling properties via Zope's management screens. API functions manage_changeProperty, manage_editProperty work fine, so maybe it's an error in generated HTML forms, or in processing of these forms. ololo

RE: [Zope] LoginManager UserSources

Hi Danny, I don't think the question applies, as you are prettymuch free to build a UserSource to anything you want. Of course, with that freedom comes aggrevation. ;-/ There is ready documentation on the Zope site for interfacing LM to SMB for authentication. I've gotten it working with Postgres (with crypted passwords no less!) It took me a couple of weeks on and off to finally get that going. Yes, it was painful, especially having no prior experience with GUF (or much experience with Zope, for that matter...) I've not made it a very high priority, but I'm working on a LoginManager/PostgreSQL walkthrough hoping that I might save someone else some grief. That info should be easy to translate for any other datasource full of users you might have in mind.
