We are working on a consulting engagement developing a suite of Zope applications centered around authentication/access control info from an LDAP server. We are very hopeful that LDAP will continue to congeal as the lingua franca for directory services. It might mean we've had to invent something for the, dare I say it, last time? :^) --Rob

Calling SQL methods in external methods with passed parameters?
by Michael Collins 16 Jul '99

16 Jul '99

HI, I want to call a Z SQL method in an external method and pass to it the relevant parameters. Any clever hints on how to do so? I was under the impression that something akin to rendering DTML pages might work. So I tried: REQUEST.form['level_id']=10 sqlvals = sqlcall(sqlcall,REQUEST) And I'm getting empty data back. Am I missing a field in the request?

Re: ZClass Meta Types

Jason, I discovered that my CVS was actually, in fact, not updating anything :( I just installed 2.0a4 from the tarball and everything looks good now. Kevin Jason Spisak wrote: Kevin, As of 10:00 AM PST the CVS update seems to still hold the original meta_type name in the add menu and all other mate_type menus. If you changes it in the ZClass Basic tab, it changes on the Basic tab page, but not anywhere else. Is this still a problem for you? Jason Spisak webmaste-(a)mtear.com

Kent, > Plese report back with how you use things like this. It's only neat > to see one's ideas be used, but what's really cool is when someone > comes up with something I can learn from. :^) Well I don't know if you can learn from me, but here's how I've used it. Each user can create objects that have a calendar_date property, which means that they have some scheduling significance. I use the ZCatalog to show me the things that occur on the day that the Calendar is set to. In month mode I munged a way to make the date red if they have things occuring on that day. Also, the owner is just a property where I store the user name when the ZClass instance get created. I index them by owner, and calendar_date. This way all users log on to the same page, and all of them see "thier" calendar. Not pretty, but it works-->  <center>   <a href="">     </a>     <a href="">: </a>   <form> <center> <table> <tr> <td> An Appointment is something other than an Interview or Offer, or anything else in the system related to recruiting. To create the appointment click "New Appoinment" <input value="New Appointment" type="submit"> </td> </tr> </table> <center> </form>  <a href="">     </a>   <a href=""></a>     </center>  Of course in Zope 2 it's giving me the error about the tuple, but it worked like a charm with the early version of the Catalog and Zope 1.10.

BTW: CalendarTag

Kent, >They are getting > set, but the new values aren't always being retained in the object. > They are reverting back to an earlier value with each bobo_traverse > call except the very first one... As in I can only set the variable > one time and have it retained. Truly strange. Sounds like a caching effect of some kind. I'm not that with traversing. It's get me caught up. I ask, "where the heck is it getting that from the namespace?" Oh, BTW, I was futzing with the CalendarTag and found this. Just a heads up. I love the CalendarTag, I thought you should know :). With the ZCatalog it makes for a powerful scheduler. Anyway, I test to see if the day on the calendar is the same as a the day value of a calendar_date property. It worked like a charm in Zope 1.10, but I get a 'tuple' object AttributError in Zope 2. I'm not sure if this is the DateTime module, or the CalendarTag so I sent it to the list as well. Error Type: AttributeError Error Value: 'tuple' object has no attribute 'dayOfYear' <snip> File /home/mike_weltz/Zope/lib/python/DocumentTemplate/DT_In.py, line 689, in renderwob (Object: Catalog(recruiter=AUTHENTICATED_USER.getUserName())) File /home/mike_weltz/Zope/lib/python/DocumentTemplate/DT_Util.py, line 315, in eval (Object: calendar_date.dayOfYear()==date.dayOfYear()) File <string>, line 0, in ?

Kent, > Thanks for the info. You bet. >I can probably fix, > but it would be with the new TinyTables, which is utterly and > completely different than the old stuff. I use it just to store long select lists, so that probably wouldn't be affected. I'm sure the Zope world would love a Zope 2 compatible TinyTables, since I know everybody uses it for something ;) It's just so perfect for so many little jobs!

DA Update: BLOBs
by Christopher Petrilli 16 Jul '99

16 Jul '99

Gang, A few people have brought up the support, or lack of support, for BLOBS in the Zope DA products. This is something we're acutely aware of, and we have a customer now who will probably require support for a project we are doing for them. This means we're beginning to deal with the issues surrounding implementing support, which include: * Support for statement handles * Passing data by reference * Extensions to the sqlvar tag These are all interrelated because of some quoting rule issues. One of the details you will probably see introduced at the same time, is a couple of new fmt options for sqlvar: <dtml-sqlvar foo fmt=varchar> <dtml-sqlvar foo fmt=varbin> These are taken from the ODBC standard, and are probably the most agnostic of options available. It is important to distinguish between text and binary BLOBs because of the nature of statement handles. What are statement handles you ask? Well, quite simply, they are pre-digested SQL queries that are held on the server side (somewhat like anonymous stored procedures, but they don't survive connections). You can then call them, substituting data in by reference. This allows you to pass in large quantities of data in a clean manner. It also allows you to go through the query parser and optimizer once, rather than each time. What is the implication of this? Well, it means that there will probably be some new options on ZSQLMethods that you can set. One of them will be "hold as statement handle" which will only be possible on methods which have SQL components which have *nothing* but <dtml-sqlvar> statements in them. Anything else, any OR or AND processing and it no longer becomes feasible. The check-box will be a suggestion to the connection to hold it, but the connection can choose to ignore this if it isn't supported, or if by some reason, the number of handles allowed is already exceeded.
