Re: [Zope] "indirection" problem
by David Coe 03 Aug '00

I *think* you've stumbled upon the way _.getitem behaves by default: (from the DTML reference) getitem(name,flag) Lookup a name in the namespace. If the value is callable and the flag is true, then the result of calling the value is returned, otherwise the value is returned. flag defaults to false. so "_.getitem(file, 1)" will probably do what you want. But that's also basically the same as <dtml-var file> -- did that not work for you?

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

(This is one of the first things > I built into Apache so many years ago.) LM is a fantastically versatile product, which also makes it a potentially major PITA. 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.

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-
